This study was conducted to reveal the effects of local climatic conditions on the vegetative growth in a mature stand of Korean white pine based on climatic estimates. For this, the annual increments of stand variables such as DBH, height, basal area and volume were measured and estimated for seven years from 1974 to 1980. The local climatic conditions in the study site were also estimated by both a topoclimatological method and a spatial statistical technique. The local climatic conditions were then correlated with and regressed on the growth factors to reveal the relationships between the climatic estimates and the growth. It is found that relatively high temperatures had positive effects on the diameter growth. The yearly diameter growth increased when each of mean, maximum, and minimum temperature during the growing season was high. Height growth showed positively significant correlation with three climatic variables. The most important variable influencing height growth was the average of maximum temperature for 10 months from January to October. It means that the higher the average of maximum temperature for 10 months from January to October is, the more height growth of Korean white pine increases. Other climatic variables related to height growth were average of minimum temperature for 3 months in the early growing season and mean relative humidity for the growing season. Six climatic variables related to temperature had effects on basal area increment and all of them were positively correlated with basal area increment. Especially, temperatures from January to March were important factors affecting the basal area increment. In volume increment, high correlation was also recognized with most of temperature variables. This tendency was the same as the results in diameter and hight increments. This means that the volume growth increases when temperatures during the growing season are relatively high.

This study compares body types among the Korean, Northern Chinese and South Chinese women in their thirties. The subjects of this study are 30-39 year old females that consisted of 200 people from Southern China, 200 people from Northern China, and 202 people from Korea. The results are as follows. There are differences among Northern Chinese, Southern Chinese and Korean women. Korean women are taller than both regions of Chinese women, hip height measurement and waist height measurement of Korean women's are higher than Chinese women, it means that Korean women's lower body parts are longer than Chinese women. Northern Chinese women have the highest circumference measurements and depth measurements; however, Southern Chinese women have similar measurements with Korean women. The body type classification according to the GB/T 1335.2-2008 shows that Northern and Southern Chinese women have different body types. Southern Chinese women are mainly in "A body type" and Northern Chinese women are mainly in "B body type". The body type classification according to the KS K 0051 shows that Chinese women are all mainly "H body type", Korean women are mostly in "A body type". This study articulated specific differences in body types among Southern Chinese, Northern Chinese, and Korean women, especially between Northern and Southern Chinese women. This study provides basic data for Chinese female somatotype research and Korean fashion brands.

Objectives : This study mean to confirm the antibacterial activity of a garlic extract widely culturing in our region and was to determine the effect of dentifrice containing 0.1% extracts of garlic on dental plaque and gingivitis in a double blind and clinical studies in 50 healthy adults aged from 20 to 22 years who provided a consent for their participation. Methods : The antibacterial activity was evaluated using triple distilled water and the Kirby-Bauer disk diffusion method and the minimal inhibitory concentration(MIC) against various pathogens for periodontal disease, such as P. gingivalis 381(ATCC33277), was estimated. The experimental groups classified according to the concentration of garlic extract used: 10,000ppm(A), 5,000ppm(B), 2,500ppm(C), 1,000ppm(D). Oral examination of subjects was performed through clinical periods and on day of baseline, 6, 12, 19, 25 days plaque index and gingival index were scored by Turesky' modified index and Loe & Silness index. After 12, 19, 25 days use of their respective dentifrices, statistically decreases of plaque index, gingival index were shown in both the experimental and the control group, respectively. Results : There was significant antibacterial activity in the "2,500ppm(C)" group against P. gingivalis 381. Experimental group exhibited significantly the lower plaque levels and the higher levels of gingival health by the use of the dentifrices contained extract of garlic from 6 days compare with control group(p<0.05). The degree of decrease was more significant on gingivitis level of the experimental group than the control group(p<0.05). Conclusions : This findings indicated that the oral products containing a garlic extract is effective in preventing and treating periodontal diseases, and has potential value in inhibiting periopathogens.

The seasonal variations of digestive diverticula in the scallop, Patinopecten yessoensis culturing by sowing method were studied by microscopic observations and individual measuring of the shells collected monthly from Abashiri Bay located in Hokkaido, Japan. Digestive diverticula index revealed the seasonal variations which showed the highest value in May and July, and the lowest value in December through April. The highest number of tubules per $mm^{2}$in the preparation of digestive diverticula was counted in March. But, in September and October the number of tubules decreased to the lowest value. The relationship between gonad index(X) and percent of lipid tubule(Y) as an indicator for the transference of lipid in digestive diverticula into the gonad was expressed by an exponential equation, $Y=145.6X^{-0793}$. It was suggested that the lipid in digestive diverticula showed the seasonal variations might be transferred into the gonad.

The present study surveyed 300 adults who completed orthodontic treatment to determine their oral health-related quality of life and changes in oral health behavior in orthodontic patients. The collected data is analyzed using the spss 22.0 program. Before orthodontic treatment, social factors (4.68) had the lowest associated quality of life score, and after orthodontic treatment, socially related quality of life showed the highest increase at 3.72 points. Changes in oral health behavior showed that many phosphorus scaling increased by 1.28 points after correction compared to before correction. As oral health quality of life and oral health behavior have changed through orthodontic treatment, dental professionals need to take appropriate management of each patient's individual quality through health education. Appropriate management needs to be developed.

A computeized least-cost formulation program was applied to process emulsion-type sausages. The input data in formulation were utilized with the database which had been established in the previous study. The formulation results may provide Korean meat processors with actual examples. Meat-grade system made these examples more useful. The results of manufacturing test were as follows. The actual cohesiveness from manufactured sausages didn't correspond to the predicted values, but increased as the predicted values increased. These gabs caused by the different processing conditions between the model system and the actual processing. Hardness as well as cohesiveness could be used as the desirable index of a sausage texture. Comparing the cohesiveness and hardness of commercial frankfurters with those of test sausages, bind value constraint of $0.16{\sim}0.17$ in this test formula can be utilized for an actual formulation.

We note that the dynamics of realized volatilities (RVs) are near the boundary between stationarity and non-stationarity because RVs have persistent long-memory and are often subject to fairly large outlying values. To forecast realized volatility, we consider a new method that adaptively use models with and without unit root according to the abnormality of observed RV: heterogeneous autoregressive (HAR) model and the Integrated HAR (IHAR) model. The resulting method is called the IHAR-O-HAR method. In an out-of-sample forecast comparison for the realized volatility datasets of the 3 major indexes of the S&P 500, the NASDAQ, and the Nikkei 225, the new IHAR-O-HAR method is shown superior to the existing HAR and IHAR method.
