We have developed solar observational system in the department of Astronomy & Space Sciences of KyungHee University, in order to monitor solar activities and construct solar database for space weather forecasting at maximum of 23rd solar cycle, as well as an solar education and exercise for undergraduate students. Our solar observational system consists of the full disk monitoring system and the regional observation system for H a fine structure. Full disk monitoring system is made of an energy rejection filter, 16cm refractor, video CCD camera and monitor. Monitored data are recorded to VHS video tape and analog output of video CCD can be captured as digital images by the computer with video graphic card. Another system for regional observation of the sun is made of energy rejection filter, 21cm Schmidt-Cassegrain reflector, H a filter with 1.6A pass band width and 375×242 375×242 CCD camera. We can observe H a fine structure in active regions of solar disk and solar limb, by using this system. We have carried out intense solar observations for a test of our system. It is found that Quality of our H a image is as good as that of solar images provided by Space Environmental Center. In this paper, we introduce the basic characteristics of the KyungHee Solar Observation System and result of our solar observations. We hope that our data should be used for space weather forecasting with domestic data of RRL(Radio Research Laboratory) and SOFT(SOlar Flare Telescope).

The purpose of this study was to investigate selected nutrient intakes, dietary atherogenesity, energy balance and activity level of college students. One hundred and thirty one students (61 males and 70 females) made their three-day dietary records and one-day activity records along with one-day dietary records. BMI of the surveyed students was 22.33 for males and 20.28 for females. Average calorie intakes of male and female students was respectively 2166.20㎉ and 1793.60㎉. Females had slightly higher fiber intakes than males in terms of fiber g/1000㎉. Carbohyrate, protein and fat ratios in energy composition of males and females were respectively 56.62 : 15.33 : 24.70 and 57.64 : 16.49 : 25.79. Average cholesterol intakes of male and female students were 295.66㎎ and 259㎎ respectively. The male showed higher saturated fat intake, and had higher atherogenic indices of diets such as cholesterol index(CI) and cholesterol-saturated fat index(CSI) than the female. Males spent an average of 1039.00㎉/day compared to females of 687.93㎉/day for all physical activities. Most students participated in light(100% of males and females) and moderate(33% of males and 3% of females) activities level. Few students spent time at severe and very severe activity level. Seventeen of the 131 students were in positive energy balance whereas 83% were in negative balance. Both genders with positive energy balance tended towards smaller weight and BMI, and larger food intakes than those with negative energy balance. Students with positive energy balance had higher saturated fat intakes and dietary atherogenic scores of CI and CSI than the counterparts with negative energy balance. Males with positive energy balance had decreased physical activity and daily energy expenditure whereas increased food and saturated fat intakes. Females with positive energy balance had significantly increased food, saturated fat and sugar intakes.

대전지역 대학생들에 의한 대학급식소의 급식평가를 조사하기 위하여 3개 대학의 남녀 대학생 309명에게 설문 조사한 결과를 요약하면 다음과 같다. 1. 학생들이 대학급식소를 평가한 것 중 음식 및 메뉴의 특성에 대해서는 음식의 양, 영양가는 대체로 적절하다고 평가되었으나 온도, 신선도, 계절음식의 이용성, 식단의 변화, 메뉴선의 다양성은 만족하지 못하고 있는 것으로 나타났으며, 학교별로는 B학교가 맛, 외관, 영양가, 신선도, 식단의 변화, 가격 등에서 낮은 점수평가를 하여 불만족한 것으로 나타났다. 2. 위생 및 종업원의 태도에 대한 평가에서는 전체적으로 종업원의 위생, 배식시 신속함, 용모의 단정함, 친절함은 보통으로 평가되었으나 음식의 위생, 식기의 청결은 만족하지 못한 것으로 평가되었으며 A, B학교는 음식의 위생에서 낮게 평가되었고 B학교는 식기의 청결에서 낮게 평가되었다. 3. 식당시설에 대한 평가에서는 전체적으로 식탁 및 의자배치, 반납구의 위치, 카운터의 위치, 메뉴판 사용, 환기시설 등은 보통 정도라고 평가하였으나 실내장식, 난방시설은 낮은 평가점수를 나타내었다. 학교별로는 A학교는 식탁 및 의자배치, 카운터의위치, 난방시설, 실내장식 등에서 낮은 점수를 보여 불만족한 것으로 나타났으며 B학교는 메뉴판사용에서 평가 점수가 낮았다. 4. 식당분위기 및 편리성에 대한 평가에서는 전체적으로 조용함, 편안함에서 불만족하게 나타났고, 식당의 위치, 식당 운영시간, 줄서는 시간은 적절하다고 평가되었으며, 휴식공간은 평가점수가 낮았다. 학교별로는 A학교가 줄서는 시간, 휴식공간에서 낮은 평가점수를 나타내 개선해야 할 것으로 생각되며 C학교는 줄서는 시간에서 낮은 평가점수를 나타냈다. 줄서는 시간이 길어 학생들에게 불편함을 주는 요인은 배식시간의 짧음, 식권의 제한 판매, 카운터의 위치, 강의시간표의 영향 등이 관계하고 있었다. 전체적으로 볼 때 음식의 온도와 신선도, 계절음식의 이용성, 식단의 변화, 메뉴선택의 다양성, 음식의 위생, 식기의 청결, 실내장식, 난방시설, 휴식공간 등은 낮은 평가점수를 나타내 대학급식에서 만족하지 못하고 있음을 알 수 있다. 이상의 결과를 살펴볼 때 대전지역 대학급식소에 대한 학생들의 급식평가는 전반적으로 만족하지 못하고 있는 것으로 나타났다. 이는 앞으로 더욱더 급식의 품질향상을 위해 노력해 나가야 할 것으로 보며 이를 위해서는 음식의 맛, 위생, 식단의 다양화, 급식시설 등에 더욱 개선을 하여 보다 나은 급식을 제공할 수 있어야 하고, 또한 급식 대상자들이 만족한 급식을 할 수 있도록 급식관리자들은 적극적이고 다양한 급식평가를 통해 문제점을 재검토하여 보다 효과적인 급식운영을 해야 할 것으로 사료된다.

This study examined the rates of spinal abnormal curvature and the correlation of the Body Mass Index (BMI), Low Back Pain (LBP) and spinal curvature by measuring scoliosis, kyphosis, and lordosis in university students. The study population included 67 male, 92 female university students, making a total of 159, in Wonju City. Spinal curvature was measured by an electrogoniometer in a computerized skeletal analysis system. Lateral curvature of spine of more than 10 degrees was considered as nonspostural scoliosis. The correlation of BMI, LBP and the spinal curvature was analysed by Pearson's correlation coefficient and t-test. The following results were obtained: 1. The overall incidence and rate of scoliosis in cases with a greater than 10 degree curve in males was an incidence of 8 and a rate of 11%. In females the incidence was 36 and the rate 39.2%. 2. The overall incidence and rate of kyphosis of less than 20 degrees in males was a rate of 9 and an incidence of 11.9%. In females, the rate was 5 and the incidence 5.4%. In kyphosis cases of more than 40 degrees, the male rate was 5 and the incidence 7.7%. For female the rate was 13 and the incidence 14.2%. 3. The overall incidence and rate of lordosis with curves of less than 20 degrees was a rate of 6 for males and an incidence of 9.0%. For females, the rate was 5 and the incidence 5.4%. In cases of more than 50 degrees lordosis, the female rate was 2 and the incidence 2.2%. There were no males in this category. 4. There was a negative correlation between kyphosis and BMI. The greater the kyphotic curve, the less the BMI in males (p<0.05). There was no significant BMI difference by gender in either scoliosis or lordosis. There was, however, a significantly decreased sacral angle in the female group with LBP. The results of this study cannot be generalized to the general population because the subjects were all from one university. The measurements were quite reliable because the angles determined by the Metrocom System were highly correlated with radiologic findings. This study shows the need for a regular screening system for spinal curvatures in university health examination procedures.

The purpose of this stud was to investigate the degree of recognition as well as the consumption pattern of convenience food products, and related factors among 700 mixed Korean college students using written questionnaire. Students of Seoul region showed the significantly lowest rate of recognition at 36.7%. Results also showed that lifestyles have a significant effect on the degree of recognition of convenience foods. The consumption patterns of convenience foods goes as follows: used frequently-18.2%, once in awhile-73.9%, doesn't use-7.9%. The higher the recognition rate, the higher the consumption rate for convenience foods. When compared in terms of residence, students living at home used more refrigerated foods compared to students living outside of the home. Among the total students living outside of the home, students living on their own scored highest of convenience food consumption. In the case of female students living outside the home, respondents living alone and in dormitories scored the highest. Female students living in dormitories were mainly using refrigerated and canned foods, while those living alone consumed more kimbap and 'sa-bal-myun' in convenience stores. Korean college students mainly consumed frozen food, retort food, and kimbap in convenience stores. The college student that believes that 'You eat to satisfy hunger' significantly used more convenience food while those that marked 'maintain health' consumed the lowest showing a great difference between groups. Results showed that the lower the food habit score, the higher the usage score of convenience foods. The food habit score had a negative correlation with the usage of frozen foods, instant food, and convenience store food. When compared individually, packaged 'ramen' and 'sa-bal-myun' scored the highest points of usage. Frozen fried rice and pre-packaged rice scored the lowest points indicating Korean college students do not consider rice a convenience food. Convenience food consumed in convenience stores ranked the highest among places of consumption, compared to places like home or outdoors; showing that convenience foods were used by people with limited time constraints.
