Objective : This study was conducted to infer the effect of superficies-resolveing herbs by analyzing effect terms which have extracted and refined, based on four temperatures and five tastes. Method : Firstly, temperatures, tastes and effect terms were extracted from the 27 kinds of superficies-resolving herbs written in Herbology. Then, each effect terms was divided into single meaning term and refined as typical term, using the inclusive effect terms I established. After that, herbs were grouped by tastes and found the effect terms which are mentioned most frequently. And it could be supposed to be classified into each herb's new effects based on the relationship between properties and those effect terms. It is also inferred into new tastes from some herbs by analysing the representative effects group of each taste and finding which other tastes can be related to each herb's effect. Result & Conclusion : All the superficies-resolving herbs can have wind-dispelling effect and superficies-resolving effect, except Bulpleuri Radix. This herb is able to has just the wind-dispelling effect. And it's more appropriate to categorize Bulpleuri Radix to heat-clearing herb group than superficies-resolving herb group, considering its several, distinctly cold characteristics. Some effects are concentrated to wind-cold-dispersing herb group and others to wind-heat-dispersing herb group. Each tastes has its own representative effect group. And, according to its tastes' representative effect, some of herbs are reasonable to get new effect term. With not so feasible reason, 4 kinds of herbs are supposed to contain all of hot, bitter, and sweet tastes. Also It's needed to study much deeper whether Perillae Herba, Zingiberis Rhizoma Crudus and Elsholtziae Herba are belong to superficies-resolving herb group or to interior-warming or damp-dissolving aromatic herb group.

This study was performed to investigate what effect the taste and quality of drugs would have on the cold and heat mechanisms of human body. We administered Hwangryeunhaedok-tang composed of bitter-tasted, cold-qualified drugs and Gungangbuza-tang composed of spice-tasted. hot-qualified drugs, respectively to the mice 1 hr before exposure to heat stress or cold stress. Plasma corticosterone level of mice was measured. The results were as follows: 1. The elevated corticosterone level in the mice exposed to heat stress was significantly decreased after administration of Gungangbuza-tang but there was no decrease after administration of Hwangryeunhaedok-tang. 2. The elevated corticosterone level in the mice exposed to cold stress was significantly decreased after administration of Hwangryeunhaedok-tang but there was mild decrease after administration of Gungangbuza-tang. 3. When the doses, 3g/kg and 1g/kg were administerd to mice exposed to heat stress. both dose showed significant decrease of corticosterone level and the dose. 3g/kg was more effective. However, in the mice exposed to cold stress, the dose, 3g/kg showed mild decrease and 1g/kg showed significant decrease. These data suggested that HW decreased the plasma corticosterone level in the mice exposed to cold stress and GB also decreased the plasma corticosterone level in the mice exposed to heat stress. In conclusion, our study revealed that the taste and quality of drugs controled the cold and heat mechanism of human body.

Among OECD countries, Korea is the only country which has continuously recorded total birthrate below 1.3 person for over 10 years. Since 2006, the Korean government has promoted the population policy in full scale. But, the fertility rate which became low has not shown any sign to go up again. Thus, Korea can be understood as having fallen into 'low fertility trap'. Such a low fertility can cause serious problems such as weakening of national competitive power and even survival of the country. In Korea, due to studies and finding jobs among young women, their childbirths are kept being postponed. In some cases, poor working conditions where women work can cause physical conditions not appropriate for pregnancy. Thus, it is very important to let childbearing women, pregnant women take care of their health. Accordingly, conscious of this low fertility era, this study examined major international organizations and countries' health promoting strategies-with focus on motherhood and suggested some methods to effectively improve health for motherhood.

Deficiency of collagen regeneration, denaturalization of fibers, increased melanin synthesis and reactive oxygen species are important factors inducing deterioration of healthy skin function. They induce freckles and decrease in skin elasticity. Vitamin C, vitamin A and their derivatives have been used as cosmetic ingredients for improvement of these problems but they have various problems. We have been developing the various derivatives of these ingredients. In this study, we investigated whitening effect of 3-o-cetyl-L-ascorbic acid (VCCE), a new vitamin C derivative. The VCCE inhibited melanogenesis in a dose dependent manner(44 % at $20\;{\mu}g/mL $) and tyrosinase expression. For 8 weeks, we also investigated skin brightening effect of VCCE on pigmented spots in UV-irradiated human skin. In results, VCCE showed a statistically significant skin whitening effect by mechanical and visual evaluation. Taken together, our findings suggest that the VCCE has potential benefits as an active ingredient for whitening cosmetics.

Polychlorinated biphenyls (PCBs) has been widely used as plasticizer, insulator, lubricant, paint and ink. The persistence of PCBs in the environment and their bioaccumulation in living organism make a raise concerns regarding their toxic effects in immune system and subsequent effects on human health. However little has been known about effect of PCB, an endocrine disrupter, on splenocytes. In this study, for identifying the effect on the organs and immune cell of mice by the concentration and time of commercial PCB mixture (Aroclor 1254), each 3 mice were tested at the concentration of 3, 30, 300, 1,000 mg/kg respectively, and their organ's weight were measured in 4, 7, 14 days, respectively. Also according to concentration and time, PCB was evaluated for the effects on splenocyte viability and lipopolysaccaride (LPS) and concanavaline A (Con A)-induced splenocyte proliferation on mice spleen. In liver and lung, there were significantly defferent by concentration and time of PCB (p < 0.0001). In respect of concentration of PCB, no significant effects on mice's liver by Aroclor 1254 concentration below than 300 mg/kg were observed except at the concentration of 1,000 mg/kg doses (p < 0.0001). But there was not significant different change in mice spleen by concentration and time of PCB (p=0.2206) and the mode of weight change of spleen was different to of liver and of lung. Viabilities of splenocytes were decreased following treatment with high concentration of PCB. Also, LPS and Con A-induced cell proliferations were decreased by Aroclor 1254 at 1,000 mg/kg. These data suggest that Aroclor 1254 is the immunotoxic compound that may have an effect on mouse immune system.

Objective : To estimate the status of HIV infection and AIDS incidence using a back-calculation model in Korea. Methods : Back-calculation is a method for estimating the past infection rate using AIDS incidence data. The method has been useful for obtaining short-term projections of AIDS incidence and estimating previous HIV prevalence. If the density of the incubation periods is known, together with the AIDS incidence, we can estimate historical HIV infections and forecast AIDS incidence in any time period up to time t. In this paper, we estimated the number of HIV infections and AIDS incidence according to the distribution of various incubation periods Results : The cumulative numbers of HIV infection from 1991 to 1996 were $708{\sim}1,426$ in Weibull distribution and $918{\sim}1,980$ in Gamma distribution. The projected AIDS incidence in 1997 was $16{\sim}25$ in Weibull distribution and $13{\sim}26$ in Gamma distribution. Conclusions : The estimated cumulative HIV infections from 1991 to 1996 were $1.4{\sim}4.0$ times more than notified cumulative HIV infections. Additionally, the projected AIDS incidence in 1997 was less than the notified AIDS cases. The reason for this underestimation derives from the very low level of HIV prevalence in Korea, further research is required for the distribution of the incubation period of HIV infection in Korea, particularly for the effects of combination treatments.
