This study aims at analyzing the characteristics of muscular men's somatotype to develop their clothing pattern. The body sizes of 168 men categorized as the muscular type according to the Somatotype Classification by Sheldon and Heath-Carter, were compared with the 5th Korean body size measurement (KBSM) conducted by SizeKorea in 2003, to analyze the characteristics of muscular men's somatotype. The results are as follows: 1. Compared to the 5th KBSM, the subject's body size is higher in the Chest, Upper Arm, Calf, Hip, and Thigh Circumference, and Thigh Thickness, and Waist Back and Biacromion Length, but lower in the Waist Circumference. 2. The subject group shows the characteristics of a wedge-shaped somatotype which has a broad chest and a slim waist, and of having a back more developed, longer and more curved, compared to the non-muscular men. 3. The study shows the subject group has the characteristics of both the wedged somatotype with wide chest and slim waist, and the X somatotype with projected hips and thighs.

PURPOSE: The study aimed to analyze the effect of pillow height on upper trapezius and sternocleidomastoid (SCM) muscle activity and overall human body comfort to determine the optimal pillow height. METHODS: The study included 32 healthy college students, of both genders, who provided prior consent. It examined three pillow heights (flat, 6cm, 12cm) and measured the upper trapezius and SCM muscles using ultrasonography, myotone, and electromyography(EMG). Muscle activation, thickness, and fatigue were assessed. RESULTS: The study found significant differences in muscle thickness and muscle tone based on the pillow heights (flat, 6cm, and 12cm) with a p < .05. The SCM and upper trapezius muscles were thinnest at a pillow height of 6cm. Muscle tone in the SCM was lower at both 6cm and 12cm pillow heights. Post-hoc measurements showed significant differences in both the SCM and upper trapezius muscles thickness at the 6cm pillow height (p < .05). Also, significant differences in muscle tone were observed only in the SCM, particularly between the 6cm and 12cm pillow heights. CONCLUSION: The ultrasonography and myotone measurements showed a significant difference in muscle thickness and muscle tension, both of which were above 6cm, while there was no difference in muscle activation. Based on the strong correlation between muscle tension and muscle thickness with pillow height, this study concluded that the human body feels comfortable with a 6cm pillow height. Therefore, it is recommended to use a pillow height of 6cm when lying in a supine position.

The purpose of this research is to investigate how obesity and eating behavior are related to the concentration of serum insulin and lipids and blood pressure of middle-aged men The sample for this study utilizes 240 middle-aged men between th4 age of 40 and 60 living in the city of Kumi. Through a process of anthropometry and categorization by relative body weight, the sample is devide into two groups, the obese group (51 men) and the normal group (129 men). The results of the study were as follows : 1111111. The men from the obese group with the exception of height, subs-capular/triceps skinfold girth ratio(STR) had a higher level of body mass index (BMI), waist and hip circumference, waist/hip girth ratio(WHR), subscapular and triceps skinfold thickness than the normal group (P=0.0001). 2. In comparing the serum insulin and lipids between the obese and normal group, the obese group had a higher level of insulin and triglyceride (P=0.016, P=0.050) but a lower concentration of HDL-cholesterol and HDL-cholesterol/total cholesterol (P=0.034, P=0.004). Also, the obese group had a higher level of systolic and diastolic blood pressure (P=0.001, P=0.029). When looking at the relationship between the serum insulin and lipids and anthropometric measurements, the relationship between waist/hip girth ratio(THR), the concentration of fasting serum insulin and lipids were stronger than the obesity index, body mass index(BMI). 3. Men who exercised regularly had a lower total cholesterol and systolic blood pressure 9P=0.049, P=0.041), and a higher level of HDL-cholesterol/total cholesterol (P=0.004). There was no observable relationship between the food habit score, the preference for fiber foods, and the concentration of serum lipids. Also, the concentration of serum lipids had no apparent effect on the preference for salty, sweet, and greasy foods.

This study was conducted to evaluate the nutritional status and diabetes management of diabetic patients in the Health Center. General characteristics, food habits, food intakes and the knowledge about diet therapy were investigated from ninety one diabetes subjects. Anthropometric assessment such as weight, hight, triceps skinfold thickness, and biochemical measurement of fasting blood glucose(FBG), post prandial 2 hours blood glucose(PP2), and hemoglobin A1c(HbA1c) were obtained form the subjects. The results were summarized as following : 1. The average of age was 60.9 years old and 83.5% of subjects was illiterate and primary school graduated. 2. Relative Body Weight(RBW) and % body muscle were 96.18${\pm}$13.6 and 33.56${\pm}$7.01%, respectively. Obese subjects whose body weight exceeded 120% of the ideal values were 3.3%. 3. The 86.8% of subjects were managed by oral hyperglycemic agents. 4. The mean of FBG, PP2, HbA1c were 140.75${\pm}$44.43mg/㎗, 7.60${\pm}$1.88%, respectively. 5. The mean daily intake of calorie was 1407㎉, and 73.6% of subjects lower caloric intake than prescribed calorie. when the degree of dietary compliance was expressed as Tunbridge score, 18.7% of total subjects was grouped as satisfactory, where as 20.9% and 60.4% could be considered as tolerable and hopeless, respectively. The nutrients intake were lower than RDA except for Vitamin A and Vitamin C and the ratio of carbohydrate : protein : fat was 72 : 14 : 14. 6. The mean score of knowledge test about diet therapy was 3.52${\pm}$2.19 out of possible 14.00 points. The above results suggested that the most of diabetic patient showed the poor nutritional status and they faced the lack of knowledge about diabetes management.

An experiment was conducted to determine the effects of soybean oil supplementation replacing tallow in pig diets at different stages of growth. One hundred and twenty crossbred (Landrace${\times}$Yorkshire${\times}$Duroc) pigs weighing 18 kg on average were selected. Pigs were randomly allotted to 12 pens of 10 pigs (5 pigs of each sex) each. Three pens were assigned to each of the four treatments: TA; tallow diet, TA-SO-80; switched from tallow to soybean oil diet at 80 kg average body weight, TA-SO-45; switched from tallow to soybean oil diet at 45 kg average body weight, and SO; soybean oil diet. Treatment SO was significantly lower in ADG than tallow diets (TA, TA-SO-80 and TA-SO-45) during the grower period (18 to 45 kg). However, treatment SO showed greatest compensation in ADFI and ADG during the finisher-2 period (after 80 kg body weight). ADFI and ADG and Gain/Feed for the total period were not significantly different among treatments. Loin area, back fat thickness, firmness and melting point of back fat were not significantly different. The levels of total cholesterol and low density lipoprotein+very low density lipoprotein cholesterol in serum were significantly lower in treatment SO than in treatments TA-SO-45, TA-SO-80 and TA. The level of serum triglyceride linearly increased as the length of the tallow feeding period increased. Serum immunoglobulin-G (IgG) level was significantly higher in the soybean oiltreatment than in other treatments. Major fatty acid composition of short rib muscle and back fat were significantly influenced by treatments. Contents of ${\alpha}$-linolenic acid (C18:3) and docosahexaenoic acid (DHA, C22:6) linearly increased as the soybean oil feeding period increased. In conclusion, soybean oil can be supplemented to the diet of pigs without significant effects on growth performance and carcass characteristics. The level of polyunsaturated fatty acids (PUFA), especially $\omega-3$ fatty acids in the carcass was increased by soybean oil supplementation.

Objective: Due to current selection practices for increased egg production and peak persistency, the production profile, age at maturity, and body weight criteria for commercial layers are constantly changing. Body weight and age at the time of photostimulation will thus always be the factors that need to be adequately addressed among various production systems. The current study was carried out to determine the effects of pullets' body weight (low, medium, and heavy) on their performance, welfare, physiological response, and hormonal profile. Methods: With regard to live weight, 150 16-week-old pullets were divided into three groups using a completely randomized design (CRD) and held until the 50th week. One-way analysis of variance was used to evaluate the data under the CRD, and the least significant difference test was used to distinguish between treatment means. Results: In comparison to the medium and light birds, the heavy birds had higher body weight at maturity, an earlier age at maturity, and higher egg weight, eggshell weight, eggshell thickness, egg yolk index, breaking strength, egg surface area, egg shape index, egg volume, and hormonal profile except corticosterone. However, the medium and light birds had lower feed consumption rates per dozen eggs and per kilogram of egg mass than the heavy birds. Light birds showed greater body weight gain, egg production, and egg specific gravity than the other categories. At 20 weeks of age, physiological response, welfare aspects, and catalase were non-significant; however, at 50 weeks of age, all these factors-aside from catalase-were extremely significant. Conclusion: The findings of this study indicate that layers can function at lower body weights during photostimulation; hence, dietary regimens that result in lighter pullets may be preferable. Additionally, the welfare of the birds was not compromised by the lighter weight group.

Cardiovascular disease (CVD) is one of the most common causes of death in elderly Koreans, and HDL-cholesterol is known to have a pivotal role in protecting against CVD. This study was undertaken to study the relationships between plasma HDL-cholesterol levels and dietary, anthropometric, and biochemical factors in elderly Koreans. The 102 subjects, who were over 60 years old, were classified into two groups based on their plasma HDL-cholesterol levels: a risk group with plasma HDL-cholesterol < 40mg/dl in men or HDL-cholesterol < 50mg/d1 in women, and a control group with higher HDL-cholesterol levels. The subjects' mean intakes of energy, calcium, zinc, vitamin A, vitamin $B_2$, vitamin E, and folate did not meet the Korean RDA for elderly people. Vitamin $B_2$ and folate intakes were significantly lower (p<0.l) in the risk group compared to the control group. The consumption of seaweed was significantly lower (p<0.05), and fish intake was 33% lower, in the risk group compared to the control group. Subjects in the risk group showed a higher BMI, waist/hip ratio, triceps skinfold thickness, and % body fat, compared to control subjects. Plasma triglyceride levels and values of the atherogenic index were significantly higher (p<0.00l) in risk group subjects. Significant negative correlations between HDL-cholesterol level and plasma triglyceride level (r= 0.37), and values of the atherogenic index (r=-0.74), were found. In summary, subjects with low levels of HDL-cholesterol were found to have relatively low intakes of vitamin B$_2$, folate, and seaweed, and higher levels of the CVD risk factors: body fat, plasma TG, and AI. These results suggest that plasma HDL-cholesterol levels can be modified by dietary, anthropometric, and hematological means.

As men in their 30s are spending more money on clothing, it is becoming increasingly important to first conduct an anthropometric study and then develop garment patterns accommodating the changes found in body sizes and types of men in their 30s, in order to effectively address their fit dissatisfaction. Thus this study aims to explore changes in upper body sizes and body types of men in their 30s, which provide basic measurements for designing major garment items including jackets and shirts. To this purpose, key anthropometric dimensions of the upper body of men in their 30s, taken from the 6th (2015) and 7th (2016) surveys conducted by Size Korea, were analyzed using SPSS 24.0 for Windows. Independent sample t-tests were conducted on major upper body sizes to track changes with measuring time. Factor and cluster analyses were used to classify body types. By comparing the two surveys, it was found that the overall body sizes of men in their 30s were increasing in height-related items, circumference, thickness, and width, -as well as body weight and BMIs. Upper body height-related items, in particular, showed a higher average value in the 6th survey than in the 7th, indicating that the overall body types of men are becoming "westernized" with longer legs and shorter torso. Finally, five factors were derived to determine the typical upper body types of men in their 30s and the body types were classified into three categories according to the cluster analysis. First, those with a relatively small build with short stature and torso. Second, those with the highest stature and vertical dimension with the smallest torso volume and least body fatness. Third, those with the biggest torso volume and most body fatness with bigger width between armpits and shoulders. The distributional pattern analysis showed that men in their 30s tend to have increasingly higher stature but lower body weight and BMIs than in the past, implying that their body types are becoming close to those of men in their 20s.

최신 방사선 치료 및 수술 기법에는 복잡한 3차원적 선량분포를 정확히 측정하는 실용적 선량분석 기기 및 기술이 필요하다. 본 연구에서는 실험실에서 제작한 겔을 방사선 치료 영역에서 선량계로 활용하기 위해 최적화된 자기공명영상 변수 조건에 대해 연구하였다. 이를 위해 각 자기공명영상 획득 조건에서 TE 시간 TR 시간, 영상 두께, 코일 등을 달리하여 조건 별로 획득한 영상을 이용하여 비교 평가하였고, 선량불확도 및 선량 분해능을 도입하여 본 연구에서 찾은 조건에 대해 평가하였다. 8% 젤라틴(300 bloom, Sigma-Aldrich, USA), 8% MAA (Metaacrylic acid, Sigma-Aldrich, USA), 10 mM THPC (tetrakis hydroxymethyl phosphonium, Sigma-Aldrich, USA), 그리고 0.05 mM HQ (Hydroquinone, Sigma-Aldrich, USA) 농도의 조성비를 가진 정상산소 중합체 겔을 실험실에서 합성하였다. 방사선 선량 전달은 Co-60 감마선 조사기 (Theratron-780; AECL, Ottawa, Canada)를 사용하였고 고체 팬텀을 사용하여 중합체 겔에 각각 0, 2, 4, 6, 8, 10, 12, 14 Gy의 선량을 전달하였다. 자기공명영상 장치의 특성상 T2 시간을 얻기 위해서는 fast spin echo 파형을 사용하였다. 일반적으로 Head Coil이 SNR이 Body coil 보다 낮아 선량 불확도가 우수할 것으로 예측하였으나, 일부 문헌에서는 Body coil이 영상 균일도가 우수하다고 하였다. 하지만 본 연구에서는 Head coil이 선량 불확도 및 선량 분해능이 모든 선량 영역에서 Body coil 보다 우수한 것을 확인하였다. TR 시간 연구에서 TR 1,500 ms와 TR 2,000 ms 간의 차이는 선량분해능에서 모두 큰 차이가 없으나 TR 1,500 ms가 조금 낮은 선량 불확도 값을 갖는 것을 보았다. MR 영상 두께가 2.5 mm일 경우 모든 TE 시간에 대해 4 Gy에서 가장 낮은 선량 불확도 값을 가졌다. 특히 TE 12 ms 경우 4 Gy 이후에는 가장 낮은값의 결과를 얻었다. 선량 불확도의 경우 6 Gy까지는 TE 시간에 따른 차이는 없으나 이후에는 TE 12 ms가 가장 나은 결과를 얻었다. 선량 불확도의 겨우 6 Gy까지는 모든 TE 시간에 대해 차이가 미미하나 8 Gy 이상에는 20 ms가 가장 우수한 선량 분해능 값을 가졌다. 선량 분해능 값 역시 NEX 3에서 가장 우수한 값을 가졌고 2 NEX일 때 가장 높은 분해능 값을 가졌다. 본 연구 결과 영상 두께와 NEX의 결과는 영상 두께가 얇은 경우 NEX가 높을수록 우수한 결과를 얻었고 영상 두께가 두꺼워 질수록 NEX가 낮아야 함을 확인했다.
