Skin color of Chinese women across different regions of China:An analysis based on both individual typology angle and hue angle

Skin color is considered an important beauty standard for women in China.The typical tool for skin color measurement,individual typology angle(ITA),was developed based on Caucasian skin features.The ITA effectively measures the brightness of facial skin,which is traditionally associated with beauty in Caucasian women.However,in Chinese women,whiteness is not the only determinant of skin esthetics,and other elements such as“yellowness”and“redness”are also important considerations.Thus,the hue angle system was developed based on the skin features of Chinese women,whose skin is typically on the“yellow-red”spectrum.Studies examining the skin color of Chinese women based on both the ITA and hue angle should be carried out.The skin colors of 4500 women aged 18–45 years across five different regions of China were measured using both the ITA and hue angle systems.The relationship of the“red pigment and melanin content”with the“brightness and redness of skin color”was also examined.Further,the different skin types of women across different regions were identified.Measurements based on the ITA system reveal a saddle-shaped distribution of skin brightness among Chinese women across five different regions,with skin brightness being high in the eastwest regions and low in the north-south regions.The ITA and hab values are not consistent in individual women,and thus,both need to be considered when evaluating skin color.Additionally,no correlation between the skin’s red pigment and melanin content and the skin’s ITA and hab values is identified.This study provides skin color data based on both the ITA and hue angle systems.The findings show that skin ITA/hab values cannot simply be explained by the red pigment/melanin content of the skin.Given the distribution of skin types across different regions of China,whitening ingredients causing little to no irritation should be used to formulate whitening cosmetics.

Effect of Hue Citadel on the Layout of Traditional Garden Houses Located in Its Area, Vietnam

In Hue, the city located in the middle region of Vietnam, the Citadel is known as the place of the last Dynasty in the history of Vietnam, Nguyen （1802-1945）. Whereas Nguyen Kings lived in the Purple Forbidden City （the third wall of the Citadel）, other members of royal families and high-ranking mandarins lived in Hue Traditional Garden Houses （HTGHs） constructed around and in the Citadel area. This paper is a part of the research that focuses on an approach for sustainable live conservation and application of HTGHs into contemporary use. In this paper, the study aims to consider effects of the Citadel on the layout and arrangement of HTGHs located in its＇ area by studying alteration in layout elements of those house. Based on field surveys of 91 HTGHs in the Citadel area, it is found that although those houses are altered into various configurations under the impacts of urbanization and modernization, several important traditional elements in layout such as Binh Phong （masonry screen）, Be Can （basin）, and facing orientation have been maintained, and their layouts reflect a miniature image of Hue Citadel, i.e., there is an integral relationship between the Citadel and HTGHs located in it. This relationship plays an important role for expressing one of unique characteristics of Hue cultural asset, which is unavailable in other regions of Vietnam.

Safe Vegetable Consumption in Hue City:A Case Study of Food Safety Situation in Vietnam

Food safety has become a growing concern for citizens in the modern society when consuming unsafe food that directly impacts public health,life quality and well-being of each country.People of Vietnam in general and specially in Hue city have been facing challenge of vegetable unsafety.A survey concerning the consumption of safe vegetables was conducted in Hue city,Vietnam.Data were collected by using a well-structured questionnaire from representative of 30 consumers,30 producers and 10 collectors.The results showed that lettuce,sweet potato and Chinese mustard were identified as the most important vegetables to consumers in Hue city.Most of the consumers purchased vegetable every day.The cost of vegetable in every transaction was about 30,000 VND.This expenditure has not created a great motivation for developing safe vegetable production.Most of the consumers in Hue city showed high interest,demand,trust and satisfaction for safe vegetable.However,50%of the consumers reported that the price of the safe vegetable was quite expensive and price was not matched with their quality.Moreover,there were some disadvantages in each stage of vegetable supply chain.For example,land,seed,capital,cultivation techniques,preliminary processing,preservation,brand name,trademark and place to consume have not met the requirement of high technology production for the supply chain of safe vegetables.The chain linking between the production and consumption of vegetables is not sustainable.Producers and consumers do not have closely links.Vegetable can not be traced to origin and there is no safe certificate.The consumers believe the quality of vegetables depending on the prestige suppliers,such as,the vegetable shops with foreign consultants.Safe vegetables of farmers are very difficult to be certified for safe vegetables.Solutions and suggestions to Hue city are proposed that it is necessary to establish the vegetable production area in Hue city.Vegetable growers should be supported with capital,knowledge,technology,vegetable preliminary processing and preservation.They should be supported to build a trademark and certificate of vegetable safety and establish the chains of effective safe vegetable consumption.

Soil Gas Radon Measurement for Identifying Active Faults in Thua Thien Hue (Vietnam)

The solid-state nuclear track detectors have long been applied to assess the activity of tectonic faults. We measured the Radon (Rn) concentration in soil gas on 09 profiles with a total of 245 measurement points in Thua Thien Hue area (Vietnam). Measurement results show that the Rn concentration in soil gas ranges from ~10 Bq/m3 to 144,570 Bq/m3. There is a clear difference in the Rn concentration on the granite rock of Dai Loc complex compared to the remaining rocks. The calculated background value and anomaly threshold of Rn concentration on the granite rock of Dai Loc complex and on the remaining rocks are 33,488 Bq/m3, 82,839 Bq/m3 and 5313 Bq/m3, 24,850 Bq/m3 respectively. Spatial distribution of Rn concentration in soil gas reflects the existence of faults since Rn concentration increases at the points above or near fault lines. The level of expression of fault activity is assessed by radon activity index (KRn), which is calculated by the ratio of anomaly value to background value of Rn concentration. According to KRn, in Thua Thien Hue area, only the Dakrong-Hue fault shows a strong expression of activity with high and very high KRn (the maximum KRn = 27.21). The Truong Son, Huu Trach River, Ta Trach River and Bo River fault zones do not show clear activity with low and medium KRn. There is no Rn anomaly value recorded on the Rao Trang fault, demonstrating that it is likely to be inactive at present. The study results indicate that the Rn concentration in soil gas is a strong evidence of the existence of faults or tectonic fracture zones as the Rn concentration always increases at the points above or near the fault line.

A color image tracking method based on target characteristic hue decision

Conventional correlation matching algorithms waste great time in invalid area search. This paper proposes a color tracking method based on correlation search area optimization on target characteristic hue decision. By quantifying and reducing dimensions of HSV（ hue saturation value） color space, a one-dimensional hue space is constructed. In the space, the target characteristic hue granule set is constructed, which contains attributes such as value, area and average distance between pixels and aiming center. By using granular computing method, the similarity between target and search blocks is obtained and the invalid search areas can be removed. The color tracking experiment has proved that the algorithm can improve real time performance for conventional matching algorithms without precision lost.
