This study was conducted to investigate the response of the human body to stress induced by wall recording of subway stations in the city center. The experiment was conducted as a simulation exercise, and six images were selected and produced based on Subway Line 2, a representative underground space in Seoul. The study participants included 24 male and female college students. A three-minute experiment was conducted, during which the participants were shown the control image and green wall image once each. To measure psychological status, the following measurement indicators were used: Semantic Differential, Positive Affect and Negative Affect Schedule and State-Trait Anxiety Inventory. Physiological changes were investigated by tracking participants' heart rate and blood pressure. Results showed that parasympathetic and sympathetic nerves were activated in the presence of the green wall in the subway station. The psychological evaluation analysis revealed that negative affect toward underground space decreased, while positive affect increased. This study found that the green wall in subway stations has a stable effect on the human body, both psychologically and physiologically. In the future, green walls in underground spaces can be used to reduce psychological stress and increase physiological relaxation.

Objective: The purpose of this study is to evaluate the usefulness of infrared thermography in patients with carpal tunnel syndrome by comparing with electrodiagnostic and ultrasonographic findings. Method: From January 2014 to October 2017, electrodiagnosis, ultrasound, and digital infrared thermal image (DITI) of unilateral carpal tunnel syndrome diagnosed in a single hospital were retrospectively analyzed. The subjects with bilateral symptoms of carpal tunnel syndrome, peripheral vascular disease, diabetes, thyroid disease, fibromyalgia, rheumatic disease, systemic infection, inflammation, malignant tumor, and other musculoskeletal disorders such as finger osteoarthritis, peripheral neuropathy, cervical radiculopathy, and the previous history of surgery were excluded. Results: Of 53 patients diagnosed with carpal tunnel syndrome, 11 were male and 42 were female. The visual analogue scale was 4.9 ± 1.9, and the duration of symptom was 11.8 ± 12.5 months. There was no statistically significant difference in the body surface temperature between the unaffected and affected sides. The severity of symptoms, electrodiagnostic findings, and cross-sectional area of the median nerve significantly correlates to each other. The temperature difference between the second fingers of the affected and unaffected sides showed a weak correlation with the amplitude of sensory nerve action potential and onset latency of compound muscle action potential, when there was no significant correlation with the other parameters. Conclusion: The difference in temperature on the surface of the body, which can be confirmed by DITI, is little diagnostic value when DITI is performed in unilateral carpal tunnel syndrome patients, especially when compared with ultrasonography.

본 연구는 광주 전남지역 중학생 732명을 대상으로 BMI 수준에 따른 식습관, 식행동, 체형인식 및 체중조절 실태에대해 조사하였으며 이에 대한 연구 결과를 요약하면 다음과 같다. BMI 수준에 따른 조사대상자의 분포는 남학생이 저체중군 27.8%, 정상체중군 45.9%, 과체중군 26.3%이었으며, 여학생은 저체중군이 26.2%, 정상체중군 53.6%, 과체중군 20.2%이었다. 남녀 중학생의 평균 BMI는 각각 $20.7{\pm}1.0$과 $20.6{\pm}0.2$이었다. 점수로 평가한 식습관과 식행동에서 남자중학생은 과체중군이 저체중군에 비해 빨리 먹는 점수가 높으며, 저녁식사의 양과 야식섭취 및 식품선택 시 기호보다 영양을 고려하는 점수는 낮았다. 여자 중학생은 과체중군이 과식과 스트레스 시의 음식 섭취와 식품선택 시 가격보다 영양을 고려하는 점수는 높았고, 야식 점수가 낮았다. 조사대상자의 신장은 남자 중학생 저체중군이 정상체중군과 과체중군에 비해 유의적으로 낮았으나, 여자 중학생은 그룹간 차이가 없었으며, 남녀 중학생 모두 실측한 신장보다 더 크기를 원하였다. 조사대장자의 체중은 남녀 중학생 모두 그룹간의 차이가 유의적이었다. 남자 중학생은 과체중군에서만 체중감소를 희망한 반면, 여자 중학생은 과체중군뿐아니라 정상체중군에도 체중의 감소를 희망하였는데, BMI가 클수록 원하는 체중과 실측체중간의 차이가 컸다. 본 연구대상자들의 인지체형은 남녀 중학생 모두 해당 군별 체형에 근접하였으나, 정상체중군에서 인지체형에 대한 왜곡경향이 높았으며, 희망체형과 인지체형의 차이가 과체중군에서 가장 컸다. BMI가 높을수록 체중조절에 대한 관심과 경험이 높았는데, 남자 중학생은 건강을 위해서, 여자 중학생은 날씬한 외모를 갖고 싶어서가 체중감량의 이유로 가장 많았다. BMI가 클수록 체형만족도가 낮으며, 희망체형과 인지체형간의 차이 값이 컸으나 스트레스는 BMI가 낮을수록 컸다. 또한 희망체중과 체형에서 실측체중 및 인지체형을 뺀 값이 클수록 체형만족도가 낮았다. 본 연구의 결과, 과체중군은 정상체중군과 저체중군에 비해 과식, 스트레스 시의 음식섭취에서 보다 바람직하지 않았으며, 스트레스와 체중 조절관심도 및 경험이 더 많아, BMI 수준에 따라 식생활 양상에 차이를 보였는데, 과체중군의 식행동과 태도가 보다 바람직하지 못하였다. 따라서 남녀 중학생을 대상으로 올바른 체형인식과 더불어 체계적인 영양교육의 필요성을 제시하는 바이다.

BACKGROUND/OBJECTIVES: Studies have indicated that university students majoring in nutrition and dietetics or sport sciences may have more obsessions associated with eating attitudes and body shape perception compared to other disciplines i.e. social sciences. Therefore, this study aimed to assess and compare the risk of eating disorders and body shape perception. MATERIALS/METHODS: Data was collected from 773 undergraduate students at the Departments of Nutrition and Dietetics (NDD) (n = 254), Physical Education and Sports (PESD) (n = 263), and Social Sciences (SOC) (n = 256).A socio-demographic and personal information questionnaire, Eating Attitudes Test (EAT-40), Body Shape Questionnaire (BSQ-34), Perceived Figure Rating Scale (FRS) were applied; and body weights and heights were measured. RESULTS: Mean EAT-40 scores showed that, both male and female students of PESD had the highest scores ($7.4{\pm}11.6$) compared with NDD ($14.3{\pm}8.3$) and SOC ($13.0{\pm}6.2$) (P < 0.05). According to EAT-40 classification, high risk in abnormal eating behavior was more in PESD (10.7%) compared to NDD (2.9%) and SOC (0.4%) students (P < 0.05). Students of PESD, who skipped meal, had higher tendency to the risk of eating disorders (P < 0.05). In parallel, body shape perception was found to be marked with higher scores in NDD ($72.0{\pm}28.7$) and PESD ($71.5{\pm}32.8$) compared with SOC ($64.2{\pm}27.5$) students (P < 0.05). Considering BSQ-34 classification, high concern (moderate and marked) for body shape were more in PESD (7.4 %) compared to NDD (5.2%) and SOC (1.9%) students (P < 0.05). The body size judgement via obtained by the FRS scale were generally correlated with BMI. The Body Mass Index levels were in normal range (Mean BMI: $21.9{\pm}2.8kg/m^2$) and generally consistent with FRS data. CONCLUSIONS: Tendency to the abnormal eating behavior and substantial body shape perception were higher in PESD students who have more concern on body shape and were not well-educated about nutrition. In conclusion, substantial concern on physical appearance might affect eating behavior disorders in PESD students.

The purpose of this study is to investigate how the lifestyles of food habits of college students relate to constipation. The results were as follows 1) All the total respondents were 541 college students.220 (40.8%) respondents were male and 321 (59.2%) respondents were female. Based on their BMIs, 55.5% of the female respondents were under-weight (BMI < 20), 16.8% of the male respondents were under-weight, as well. These results point out the fact that a high percentage of female college students are under-weight, compared to male of students. 2) Of the respondents, 59.0% reported having 1 or 2 meals per day, but their eating patterns were irregular. Of the respondents, 71.2% preferred white rice with their meals. Of the respondents,51.2% reported that they skipped breakfast. The main reasons why these respondents skipped breakfast were either that they were in a busy (44.7%), or it was their habit (38.4%). The response that their meals were nutritionally balanced was 34.6%, and the student who thought that their own meal pattern was healthful was 8.0%. 3) This research also focused on body image among female college students, and the results indicate that the majority of female respondents (62.5%) felt that they were overweight (very fatty or fatty) and 90.1% of the female respondents indicated they were interested in dieting (interest or very interest). Most of the students were involved in light or medium activity (94.2%) or no exercise (75.6%). The ratio of those who exercised was everyday only 33.6%.4) Of the respondents,48.7% reported that they had difficulty evacuating (every time very difficult, every time difficult and sometimes difficult) and 50.3% of the students reported that their bowel movements were irregular. 5) Of the females,8.2% and Of the males,0.5% were regarded as constipated.6) The life habit factors that influenced constipation were skipping breakfast, the amount of water intake and exercise.

Chromatin configuration and microtubule assembly were determined in porcine maturing and activated oocytes following intracytoplasmic sperm injection. Microtubule localization was confirmed using a mouse monoclonal antibody to $\alpha$-tubulin and detected using a fluorescent labeled goat anti-mouse secondary antibody. DNA was stained with propidium iodide. The image of microtubules and chromatin was captured using laser scanning confocal microscope. In germinal vesicle stage oocyte, sperm chromatin remained condensation and sperm derived microtubules were not observed at 8 to 12 h after sperm injection. At 24 h after injection, the sperm nucleus developed to the metaphase chromatin along the metaphase structure of female nucleus. In some metaphase I stage oocytes, sperm chromatin decondensed at 8 h to 12 h after injection, sperm aster was seen soon after sperm injection. At 24 h after sperm injection into metaphase I stage oocyte, male chromatin developed to the metaphase chromatin while female chromatin extruded first polar body and formed the metaphase chromatin. At 12 to 15 h after sperm injection into preactivated oocytes, condensed sperm nucleus was located in close proximity of female pronucleus. However, the condensed nucleus did not fuse with female pronucleus. In preactivated ocytes, injected sperm remained condensation, a few sperm organized small microtubular aster. Instead, maternal derived microtubules were organized near the female chromatin, which seem to move condensed male chromatin near to the female pronucleus. These results suggest that sperm nuclear decondensing activity and nucleation activity of centrosome during fertilization are cell cycle dependent. In absence of male functional centrosome, female origin centrosome takes over the role of microtubule nucleation for nuclear movement.

The purpose of this study was to employing MRI in the estimation of the biomechanical body segment parameters of Korean adults. for this purpose MRI study on 19 Korean living subjects were used to measurement. All the parameters that was concerned were inertial characteristics of human body mass of each segment, center of mass of them and the length of radius of gyration of them. The cross sectional images and saggital images of every 1cm interval were got using the 0.5 Tesla MRI from the top of head to the bottom of foot, whole body. And then, by tracing the images of the film and scanning them, got the area which the several tissues occupied in the image of slice. By summing the area of slice of each segment which were calculating and by multipling the density of the tissues, got the mass of segment and other inertial characteristics. The ratios of radius of gyration in both transverse axis and longitudinal axis though the segmental mass and segment length are as follow: male A : head($0.229\pm0.0029$), neck($0.256\pm0.0095$), thorax($0.374\pm0.0059$) abdomen($0.245\pm0.0020$), pelvis($0.368\pm0.0106$), thigh($0.288\pm0.0030$) shank($0.280\pm0.0043$), foot($0.277\pm0.0195$), upperarm($0.311\pm0.0074$) forearm($0.286\pm0.0051$), hand($0.253\pm0.0095$) female A : head($0.214\pm0.0032$), neck($0.254\pm0.0112$), thorax($0.295\pm0.0061$) abdomen($0.289\pm0.0021$), pelvis($0.329\pm0.0108$), thigh($0.288\pm0.0036$) shank($0.280\pm0.0047$), foot($0.243\pm0.0206$), upperarm($0.279\pm0.0083$) forearm($0.286\pm0.0048$), hand($0.229\pm0.0097$) male B : head($0.532\pm0.0006$), neck($0.533\pm0.0006$), thorax($0.658\pm0.0008$) abdomen($1.350\pm0.0022$), pelvis($0.875\pm0.0002$), thigh($0.213\pm0.0001$) shank($0.160\pm0.0001$), foot($0.152\pm0.0002$), upperarm($0.136\pm0.0002$) forearm($0.202\pm0.0002$), hand($0.273\pm0.0006$) female B : head($0.198\pm0.0002$), neck($0.335\pm0.0011$), thorax($0.238\pm0.0001$) abdomen($0.888\pm0.0001$), pelvis($1.318\pm0.0117$), thigh($0.095\pm0.0001$) shank($0.075\pm0.0001$), foot($0.181\pm0.0006$), upperarm($0.0.062\pm0.0001$) forearm($0.083\pm0.0001$), hand($0.105\pm0.0007$).

기존 의류 추천 시스템들은 사용자 자신의 신체 촬영 사진이나 신체 사이즈를 입력한 후, 사용자가 좋아하는 의류의 종류를 선택하면 그에 적합한 사진을 보여주는 수준에 머물러 있다. 이러한 추천 시스템을 이용하여 사용자가 의류를 구매할 경우, 사용자의 신체 사이즈에 맞지 않거나 어울리지 않는 경우가 다수 발생하게 된다. 본 연구에서는 기존 의류 추천 시스템들의 이런 문제점을 해결하기 위하여 사용자가 사이즈 뿐만 아니라 피부톤을 입력받아 사용자의 신체 사이즈 뿐만 아니라 피부톤에 알맞는 의류를 추천하는 시스템을 구현하였다. 본 시스템은 의류 추천을 위해 남성 상의 8가지를 대상으로 웹 크롤링을 통해 얻은 의류의 사이즈 정보를 주기적으로 데이터베이스에 저장하고, 해당 의류 이미지의 전체 픽셀을 분석하여 색감 텍스트 값을 추출하였다. 본 시스템의 성능을 확인하기 위하여 남자 대학생 100명을 대상으로 설문 조사를 실시하였으며, 70% 수준의 만족도를 보였다. 만족하지 않는 대부분의 이유는 추천 대상 의류가 한정되어 있다고 밝혀서 추후 대상 의류의 확대가 필요할 것으로 판단된다.

The purpose of this study was to investigate nutrient intake and food behavior according to the nutrition knowledge of middle school students residing in Seoul and Kyunggi-do, Korea. Anthropometric measurements and questionnaires, including 24-hr recall of dietary intake, were collected from 543 male and female middle school students. They were assigned to one of five groups according to their nutrition knowledge : very high group (VHG ; 90 - 100 score), high group (HG ; 80 - 90 score), normal group (NG ; 70 - 80 score), low group (LG ; 60 - 70 score) and very low group (VLG ; < 60 score), and comparisons were made. The mean age of the subjects was 13.7 years old. The mean height, weight, and BMI of male and female students were 161.9 cm, 52.6 kg and 20.2 kg/$m^2$, 157.0 cm, 50.4 kg, and 20.4 kg/$m^2$ respectively. Female students skip breakfast and dinner more frequently than male students do. Male students skipp lunch and eat fast foods more frequently than females do. Protein, calcium, vitamin B$_1$, vitamin B$_2$, niacin, vitamin C, fat, and animal protein intakes in females are shown to be related to their nutrition knowledge. Calcium, protein, animal protein, vitamin B$_2$and niacin intakes are significantly lower in the VLG than in the others. However, vitamin B$_1$and vitamin C intakes are significantly lower both in VHG and VLG. Fat intake in VHG is lowest. Nutrition knowledge of male students is correlated with mothers knowledge, nutrition attitude and nutritional status. On the other hand, in female students, nutrient consumption was lowest in subjects whose nutrition knowledge was highest and lowest. Therefore, nutrient consumption is affected by nutrition knowledge. However, in female students, possibly due to wrong information on diet or prejudice and outlook, nutrient consumption was low even when they scored high in nutrition knowledge. In conclusion, nutrition knowledge of male students is affected by the mothers nutritional knowledge and attitude. Therefore, nutrition education for mothers is very important. In male students, as their nutrition knowledge is low, their nutrient consumption is affect. These results indicate nutrition education and correct information for body image, balanced diet, regularity of meals and food selection for middle school students are required at both school and home.
