This study was conducted in order to investigate the effect of diet therapy on over weight and obese humans in Korea Subseng Research Institute from January 1, 1994 to August 31, 1997. The constitutions of subjects were classified mild negative, strong negative, mild positive and strong positive respectively by ecology and O-ring test. These results were obtained from the subjects who practiced at least 75% diet therapy recommended for over weight and obese human for 14~400days. The constitutions of over weight and obese human by Relative Body Weight (RBW$\geq$110%) were 89 mild negative humans, 62 strong negative humans, 56 mild positive humans and 30 strong positive humans. The constitutions of over weight and obese human by Body Mass Index(BMI$\geq$25) were 77 mild negative humans, 50 strong negative humans 46 mild positive humans and 23 strong positive humans. The negative subjects were higher than the positive subjects on over weight and obese humans. The diet therapy related to constitiution on over weight and obese humans showed RBW reduction of 6.73$\pm$0.53 on mild negative human, 7.78$\pm$1.69 on strong negative human, 6.94$\pm$0.76 on mild positive human, and 7.80$\pm$1.15 on strong positive human at p<0.001 by student paired t-test. The diet therapy related to constitution on over weight and obese humans showed BMI reduction of 1.47$\pm$0.12 on mild negative humans, 1.24$\pm$0.11 on strong negative humans, 1.59$\pm$0.17 on mild positive humans, and 1.66$\pm$0.30 on strong positive humans at p<0.001 by student paired t-test.

The negative weight can be ofter seen in Hopfield neural network, which is difficult to implement negative conductance in circuits. Usually, the inverted output of amplifier is used to avoid negative resistors for expressing the negative weights in hardware implementation. However, there is some difference between using negative resistor and the inverted output of amplifier for representing the negative weight. This difference is discussed in this paper.

Seven flue-cured tobacco(Nicotiana tabacum) varieties and their 21 progenies in Fl and F2 generation, half diallel crosses(no reciprocal), were tested for the degree of heterosis and combining abilities in sucker producing character according to topping and suckering treatment. Significant difference in number and weight of sucker was observed among seven cultivars. The values of general combining ability(GCA) were greater than those of specific combining ability(SCA) in weight and number of sucker in F$_1$ generation. In topping and suckering plot, Cocker 86, McNair 944, and Va 115 revealed the significant negative GCA effects for number and weight of sucker, but By 104 and Speight G-28 did positive GCA. Without topping and suckering, GCA effects for sucker weight in Cocker 139 and Cocker 86 were negative and those for sucker number in Va. 115 were also negative. Negative SCA values in sucker weight could be observed in F$_1$ generation of Cocker 86 X BY 104 and Speiht G-28 X Cocker 86, in F$_2$ of Hicks $\times$ Speight G-28 and McNair 944 $\times$ BY 104 in topping and suckering plot. SCA in F$_1$ of McNair 944 X Cocker 86 and Speight G-28 X Cocker 139 was negative without topping and suckering. The value of heterosis in sucker producing character of F$_1$ hybrids was positive

The purpose of this study was to investigate eating behavior and the attitude about weight control of the High School Girls. The questionnaires were completed by 519 girls’ high school students.(lived in city ; 269, in mine region ; 250) The results were as follows: 1. The average stature of them was 159.01${\pm}$5.09cm, the average weight was 51.64${\pm}$6.76kg. 2. In the present body structure of them, the underweight structure was 26.2% the normal weight structure was 58.4% the overweight structure was 15.4%. The present body structure was very different from the recognition of their own body structure. 3. The average point of the eating behavior was 52.07 and that of city(53.62 point) was higher than mine region(50.01 point). 4. The rate of going without breakfast(P<0.05) the frequency of snack(p<0.001) the eating rate of stimulus foods(p<0.05) the interest healthy food life(p<0.05) in two regions showed the significant difference. 5. The point of eating behavior in two regions showed the positive correlation in the economic level, the contentment degree of the present body structure, the conscious healthy condition. But it showed the negative correlation in the rate of going without of breakfast. On observing the difference of the tow regions, it showed the positive correlation to mother’s education career on the negative relation to the experience of the weight control in the city. In the other hand it showed the negative correlation to the recognition on degree of the present body structure in the mine region. 6. The contentment degree of the present body structure showed the negative correlation to the experience of the weight control. Also it showed the negative correlation to the rate of going without breakfast in the city.

Effect of Rolling factor on the growth and thatch accumulation in tall fescue was studied from the viewpoint of estimate the rolling factor to obtain the highest values of growth characters and analysis of thatch accumulation. Rolling factors were 1.82, 3.33, 4.29 and 4.85, respectively. The results are may he summarized as follows ; 1. Rolling factor was affected to obstructive on the growth of tall fescue. Thus, the rolling factor ( RF) had significant negative correlated with the dry weight of plant ( DW ), leaf weight (LW), stem weight (SW), dry weight of thatch (Th), number of tillers (NT) and C / F ratio. 2. Rolling factor of 1.82 was an adequate rolling factor for the growth. 3. The dry weight of thatch(Th) had significant positive correlated with DW, LW, and NT, but negative correlated with the dry weight of thatch per a tiller ( th / NT). 4. Thatch accumulation system can be shown in following diagram. yield compnents - DW ~ Th - Rf (LW, SW, NT, C/F) th/NT 5. The dry weight of thatch per a tiller(th / NT) was a concerning factor for the losses of thatch.

The combined estimator of inter- and intra-block estimators in incomplete block designs can be expressed as a weighted average of two location estimators. The weight should be between 0 and 1. However, the negative variance component estimate could result in the weight being negative or larger than 1. In this paper, we show that if two location estimators have symmetric unimodal distributions, truncating the weight to 0 or 1 accordingly improves the combined estimator under an arbitrary convex loss function.

In this study, in terms of the exercise vehicles of the weapon systems having negative buoyancy, the analysis on the operation concepts was performed and the new methods of floating to surface were proposed. In case of having negative buoyancy, the additional methods for recovering the exercise vehicle have to be considered. As parts of recovering the exercise vehicle, for floating to surface the new methods of weight discharge, weight separation and sea water discharge were proposed. The conceptual design about sea water discharge method was performed. It was confirmed that those methods could be applied to the design of the exercise vehicle having negative buoyancy.

Purpose: The study investigates the degree of maternal self-esteem, postpartal depression, and family function in mothers of normal and of low birth-weight infants. Method: A retrospective cohort design was applied to compare the variables of interest between a group of 73 mothers with normal birth weight infants and a group of 45 mothers with low birth-weight infants, using the maternal self-report inventory(MSRV), Edinburgh Postnatal Depression Scale(EPDS) and Family APGAR(FAPGAR). Result: The total mean score was 82.57 for MSRV, 8.45 for EPDS, and 6.83 for FAPGAR with no differences between two groups. A positive correlation was found between MSRV and FAPGAR, while a negative correlations between MSRV and EPDS, and FAPGAR and EPDS. Regardless of the direction of the relationship, the degrees of the correlations were stronger in low birth-weight mothers group than in normal group. Conclusion: No differences in MSRV, EPDS and FAPGAR between the normal and the low birth-weight group considered as beneficial effects of the follow-up management which low birth-weight group was engaged in. This suggested the early intervention(follow-up) for the family with risk factor(low birth-weight) could reduce negative outcomes such as the impaired maternal self-esteem and family function, and the occurrence of postpartal depression, retrospectively.
