This study was carried out using rats weighing $40{\sim}50\;g$ which were devided into seven groups with various diet compositions emphasizing fat levels of perilla seed oil for the period of 41/2 weeks. The levels of fat in the diet were 5%, 10%, 15% and animals were fed ad libitum. The results are as follows : 1) Yellow pjgmentation of both neck and tail was clearly observed in groups fed 10% and 15% level perilla seed oil without vitamin I supplementation (IV and VII). 2) The growth rate in groups fed 15% level perilla seed oil was reduced as compared to that in groups fed 5% or 10% level perilla seed oil. 3) The mean hematocrit values of 15% level perilla seed oil groups tended to be lower than those of control group, tut the differences were not significant. 4) The serum vitamin I concentration showed different value in various groups, the values of control group were significantly higher than those of perilla seed oil groups-15% level with or without vitamin E supplementation (VI and VII) and 10% level without vitamin E supplementation (IV). According to the results, 10% level-perilla seed oil in the diet can be considered safe if vitamin E is not omitted from the vitamin mixture ana the group fed 15% fat with P/S ratio of 1 appeared to be safe during the experimental period. Finally the long-term studios have to be persued in many aspects by using perilla seed oil in the experimental diet. Because rats are known t4 be quite resistant to the experimental diets, comparative studies using various animal species have to he conducted.

This study was designed to elucidate the effects of mugwort powder supplemented to high fat diets on blood components levels in rats. The levels of mugwort content in the experimental diets were divided into 12, 21, 28% and the fat levels in high fat diet was 30% of total caloie intake. Forty-nine male Sprague-Dawley rats weighing 72.5$\pm$0.3g were divided into group I(add mugwort during 8 weeks), group II(add during 4 weeks) andcontrol group. The results of this study were summarized as follows : 1. There were no difference in body weight gain and FER throughout eight weeks of experiment. The organ weights were somewhat higher in control group, but not significant. 2. The mugwort groups(I, II) were significantly higher than control group in RBC. This result showed that the mugwort affect the content of RBC. Author would like to conclude this result that the RBC content of experim-ental animal was affected by the iron in the mugwort. There were no difference among experimental groups in Hb, Hct. 3. It was noteworty that the concentration of serum glucose and triglyceride in the mugwort groups(I, II) was significantly lower than the control group. This result concluded that concentration of serum glucose and triglyceride which had become high by high fat diet were affected by the calcium or dietary fiber in the mugwort. There were no difference among experimental groups in albumin, total cho-lesterol, HDL-cholesterol.

Purpose: This study examines the impact of individual reciprocal preferences on coalition formation. The reciprocal model considers a player's own payoff, the player's perception of others' payoffs, and others' perceptions of the player's payoff. Research design, data and methodology: A reciprocal model is built to illustrate how reciprocity influences individual decisions in a coalition game and its formation. The prediction is examined with experimental evidences from a dictator game and a membership game. Results: The theoretical result suggests that the coalition formation could be unstable due to negative reciprocal kindness. The experimental findings support that negative reciprocal kindness could lead players participating in a coalition, no matter their dominant strategies are. When subjects were essential to make contributions to a coalition, they were more likely to cooperate if they were treated badly. In contrast, when subjects were unnecessary, the reciprocal kindness could enhance cooperative tendencies. Conclusions: This study reveals that the reciprocal behavior could influence individual decisions and reshape the coalition formation. In terms of policy implications, this study has shown that coalition formation could be reshaped by reciprocal prefe rences. Due to the strategic and complicated decision process in an interactive environment, a comprehensive investigation of factors would be required in a climate coalition in practice.

An attempt was made to determine individual thermal resistances of 2-lining fabrics ad 4-outer fabrics for Korean-styled clothes, and 4-lining fabrics ad 5-outer fabrics for Western-styled clothes at $19^{\circ}C$ and $24^{\circ}C$. The thermal insulation effects for different lining fabrics in Korean and Western-styled clothes were deduced in determining heart rate, rectal temperature, mean skin temperature and microclimates of subjects. The subjects were dressed experimental clothing which were made of lining and outer fabrics in question, and seated in an environmental chamber during the experiment. 1. Thermal resistances of lining fabrics : For Korean-styled clothes. nylon sheer is larger than unzosa. For Western-styled clothes, rayon, acetate, nylon(taffeta) and kalkali in that order. 2. Thermal resistances of lining fabrics combined : with outer fabrics: For Korean-styled clothes. the measured value is larger than the one of simple aggregate value. But in the case of Western-styled clothes, the measured value is smaller than simple aggregate value. 3. The effects of lining on the thermal insulation of the whole clothing: In case when subjects wore unlimited number of underwear, no matter what lining fabrics were used in Korean and Western-styled clothes less thermal insulation effects were indicated. For the case, however, if subjects wore only limited underwear, there are significant differences of thermal insulation between experimental clothings.

This research aims to examine the model of investor herding behavior in making investment decisions in the Indonesian capital market, which is influenced by social and information impacting on the value of the Book Value Per Share (BVPS). The latest stock market conditions show that most investors make the same error pattern in making investment decisions that result in losses. The experiment involves two independent variables, namely, information about BVPS and social influence. This study used a 2×2 factorial design laboratory experimental method. Data collection was carried out through treatment of a sample of 100 individual investors listed on the Indonesia Stock Exchange. Univariate Two-Way Analysis of Variance (ANOVA) statistical tool was used to test the independent variable on the dependent variable. Research results showed that the social influence originating from expert investors is more influential than the Book Value Per Share (BVPS) information on the behavior of herding investors in making investment decisions. These findings suggest that investors know their psychological factors, thereby increasing self-control and investment analysis skills. Further research can use psychological bias and other indicators of accounting relevant information such as Earning Per Share (EPS) to test herding behavior in investment decision making in the capital market.

The small number of fusion research that addresses fear-appeal and self-efficacy in the effectiveness of warning labels cause the label is not clear, then the purpose of the study is the first to examine the effect of the combination of the message. With the experimental method, a total of 240 participants were smokers consist of Indonesian university students in the age range 18-23 years. Data obtained then processed with ANOVA statistical methods and Test T. The results are consistent with previous studies that the visual warning labels more effective than the textual warning labels alone. Results also suggest that a warning label should be both visual and textual messages combined with self-efficacy. Limitations, this study does not differentiate among smokers and non-smokers, in addition to the images are used only one type of disease, so that the research needs to be done to distinguish these factors.
