This study was made to find out how health practice affect on nutrition status of the college freshmen in male and female. 400 freshmen students in 4year colleges were surveyed. Questionnaire and blood analysis were made. The contents of questionnaire contained general characteristics, health practice behavior, and food intake. The physical measurement included height, weight and blood pressure. The questions for health practice were about drinking, smoking, BMI, skipping breakfast and sleeping. Nutrient intake was expressed by DDS(Dietary Diversity Score by 5 food groups) and DVS (Dietary Variety Score) and 24-hrs recall method was used to find out the quantity of daily food intake. EAR% was calculated and NAR and MAR were produced. The results are as follows: 1) BMI was $22.77kg/m^2$ for males and $20.42kg/m^2$ for females. The ratio maintaining normal weight indicated by BMI of 18.5-23 was higher(p<0.001) for female students(63.2%) than males(56.5%). The ratio of overweight with over $23kg/m^2$ of BMI was 28.5% for males and 8.8% for females(p<0.001). 2)The ratio of drinking students was 59.4% for males and 40.6% for female(p<0.001). And the ratio of smoking students was 95.2% for males and 4.8% for females(p<0.001). 3) The ratio of poor health practice group was 35.7% for males and 25.5% for females, and that of excellent one was 25.4% for males and 33.1% for females(p<0.05). 4) In NAR, the lowest ratio was observed for the intake of Ca, Fe, Vitamin C and Vitamin $B_2$. The intake of Fe, Vitamin $B_2$ and phosphorus were different significantly according to sexuality. For Fe, female students showed lower level than male students(p<0.001). For Vitamin $B_2$, and phosphorus female students showed higher level(p<0.001). 5) In MAR, there was no difference according to sexuality in almost all of the ingredients. 6) For energy intake, male and female students showed 59% and 66% of EAR and it was insufficient for them. 7) For protein, more than 100% was obtained. The lowest ratio was observed for the intake of vitamin C 50.8%, Ca 53.6% and Fe 65.1% of EAR were obtained. The lowest intake ratio and for the intake of Fe female students obtained just 37.5% of EAR showing high risk of anemia. The intake of energy(p<0.001), phosphorus(p<0.01), niacin(p<0.05), Fe(p<0.001), and Vitamin $B_2$ (p<0.001) were different significantly according to sexuality. For Fe, female students showed lower level than male students(p<0.001). For energy, phosphorus, niacin, and Vitamin $B_2$ female students showed higher level(p<0.001) than male students. 8) For blood pressure, male students showed normal level of 120.7/79.1 mmHg, however, female students showed 114.5/75.4 mmHg lower than male (p<0.001). 9). In blood, for hemoglobin female students showed significantly lower level than that of male(p<0.001). T-Cholesterol and HDL-Cholesterol female students showed higher level than males (p<0.001), And for triglyceride male students showed higher level than females(p<0.001). Ca and Fe female students showed lower level (p<0.001).

암환자의 방사선 치료기술은 3D-CRT, IMRT, Tomotherapy로 발전해 가고 있으며 이 3가지의 치료법은 임상에서 가장 많이 쓰이는 방사선 치료기술이다. 본 연구에서는 3D-CRT, IMRT(Linac Based) 그리고 Tomotherapy 치료시 정상조직과 종양조직의 선량분포를 비교해 보고자 한다. 실험방법으로는 조직 등가물질로 이루어진 인체모형팬톰 (Anthropomorphic Phantom)을 대상으로 CT simulation을 실시(Slice Thickness : 3mm)하여 획득된 영상에 GTV를 비인두 부위로 정하고 PTV는 GTV에 2mm정도의 영역을 포함시켜 치료계획용 장비(ADAC-Pinnacle3. Tomotherapy Hi-Art System)으로 전송한다. 치료계획은 PTV의 처방선량을 7020 cGy로 설정한 후 PTV에 부여되는 선량값과 정상조직인 이하선, 구강, 척수에 흡수되는 선량값을 산출하였다. 실험결과 PTV에 분포된 선량값은 Tomotherapy, Linac Based - IMRT, 3D-CRT가 각각 6923 cGy, 6901 cGy, 6718 cGy의 선량분포를 보여 종양조직 처방선량값인 7020 cGy의 95%이상 부여되어 종양제어측면(TCP)에 부합하였으며 정상조직(이하선, 구강, 척수)은 각각 1966 cGy (Tomotherapy), 2405 cGy(IMRT), 2468 cGy(3D-CRT)[이하선], 2991 cGy(Tomotherapy), 3062 cGy(IMRT), 3684 cGy(3D-CRT)[구강], 1768 cGy(Tomotherapy), 2151 cGy(IMRT), 4031 cGy(3D-CRT)[척수]의 선량이 분포되었으며 이는 정상조직 합병증발생율(NTCP)의 선량을 넘지 않았다. 모든 치료기법에서 종양조직과 정상조직이 선량분포측면에 부합하였다. 3D-CRT의 치료법이 선량분포 면에서 가장 양호하지 않았지만 종양조직제어율(TCP)과 정상조직합병증율(NTCP)을 고려해 볼 때 기준치를 벗어나지 않는 선량이 분포 되었다. 상대적으로 선량분포가 우수한 Tomotherapy, IMRT는 오랜 치료시간 때문에 폐쇄공포증환자나 호흡불량 환자가 치료받는데 어려울 수 있다. 특히 토모테라피의 경우 치료 전에 고에너지 컴퓨터 단층촬영을 매일 실시하기 때문에 불필요한 방사선 피폭을 초래할 수 있다. 결론적으로 Tomotherapy가 선량분포에서 가장 우수한 치료기법으로 평가되었으며, IMRT, 3D-CRT의 순으로 방사선치료의 적합성을 보였다. 하지만 실제 치료시 환자의 상태에 따라 제한적으로 3차원 입체조형치료를 시행하여도 무방하다고 사료된다.

This paper empirically examines factors that potentially influence the success of a Web-based semantic search engine. A research model has been proposed that shows the impact of quality-related factors upon the effectiveness of a semantic search engine, based on DeLone and McLean's(2003) information systems success model. An empirical study has been conducted to test hypotheses formulated around the research model, and statistical methods were applied to analyze gathered data and draw conclusions. Implications for academics and practitioners are offered based on the findings of the study. The proposed model includes three quality dimensions of a Web-based semantic search engine-namely, information quality, system quality and service quality. These three dimensions each have measures designed to collectively assess the respective dimension. The model is intended to examine the relationship between measures of these quality dimensions and measures of two dependent constructs, including individuals' net benefit and user satisfaction. Individuals' net benefit was measured by the extent to which the user's information needs were adequately met, whereas user satisfaction was measured by a combination of the perceived satisfaction with search results and the perceived satisfaction with the overall system. A total of 23 hypotheses have been formulated around the model, and a questionnaire survey has been conducted using a functional semantic search website created by KT and Hakia, so as to collect data to validate the model. Copies of a questionnaire form were handed out in person to 160 research associates and employees working in the area of designing and developing semantic search engines. Those who received the form, 148 respondents returned valid responses. The survey form asked respondents to use the given website to answer questions concerning the system. The results of the empirical study have indicated that, of the three quality dimensions, information quality was found to have the strongest association with the effectiveness of a Web-based semantic search engine. This finding is consistent with the observation in the literature that the aspects of the information quality should serve as a basis for evaluating the search outcomes from a semantic search engine. Measures under the information quality dimension that have a positive effect on informational gratification and user satisfaction were found to be recall and currency. Under the system quality dimension, response time and interactivity, were positively related to informational gratification. On the other hand, only one measure under the service quality dimension, reliability was found to have a positive relationship with user satisfaction. The results were based on the seven hypotheses that have been accepted. One may wonder why 15 out of the 23 hypotheses have been rejected and question the theoretical soundness of the model. However, the correlations between independent variables and dependent variables came out to be fairly high. This suggests that the structural equation model yielded results inconsistent with those of coefficient analysis, because the structural equation model intends to examine the relationship among independent variables as well as the relationship between independent variables and dependent variables. The findings offer some useful implications for owners of a semantic search engine, as far as the design and maintenance of the website is concerned. First, the system should be designed to respond to the user's query as fast as possible. Also it should be designed to support the search process by recommending, revising, and choosing a search query, so as to maximize users' interactions with the system. Second, the system should present search results with maximum recall and currency to effectively meet the users' expectations. Third, it should be capable of providing online services in a reliable and trustworthy manner. Finally, effective increase in user satisfaction requires the improvement of quality factors associated with a semantic search engine, which would in turn help increase the informational gratification for users. The proposed model can serve as a useful framework for measuring the success of a Web-based semantic search engine. Applying the search engine success framework to the measurement of search engine effectiveness has the potential to provide an outline of what areas of a semantic search engine needs improvement, in order to better meet information needs of users. Further research will be needed to make this idea a reality.

Quinoa (Chenopodium quinoa Willd.) is one of the ancient crops cultivated in the Andes region at an altitude of 3,500-4000m in Chile and Bolivia from 5000 BC. It contains a large amount of protein, minerals and vitamins in comparison with other crops. The cultivation area has been increasing worldwide because of its excellent resistance to various abiotic stress such as salinity, drought and low temperature. ${\gamma}$-Ray radiation of high dose is often used as a tool to induce mutations in plant breeding, but it has a deleterious effect on organisms. However, the radiation may have a positive stimulatory effect of 'hormesis' in the low dose range. This experiment was carried out to investigate the optimum dose range for creating the quinoa genetic resources and to investigate the hormesis effect at low dose on the quinoa. This experiment was performed for 120 days from November, 2016 to February, 2017 in the greenhouse of Gyeongsang National University. ${\gamma}$-Ray radiation was irradiated to seeds at 0 Gy, 50 Gy, 100 Gy, 200 Gy, 300 Gy, 400 Gy, 600 Gy, 800 Gy and 1000 Gy for 8 hours. (50 Gy) using the low level radiation facility ($Co^{60}$) of Cooperative Research Institute of Radiation Research Institute, KAERI. Fifty seeds were placed on each petri dish lined with wet filter paper and germination rate was measured at a time interval of 2 hours for 40 hrs. The length of the root length was measured one week after germination. Each treatment was carried out in 3 replicates. The growth of seedlings were investigated for 10 days after transplanting of 30 day-old seedlings. The plant height, NDVI, SPAD, Fv/Fm, and panicle weight were measured. The germination rate was highest at 50Gy and 0Gy and the rate of seeds treated with 400Gy or higher rate decreased to 25% of the seeds treated with 50Gy. The emergence rate of seedling in pot experiment was higher at the dose of 200 Gy, 300 Gy and 400 Gy than at 0 and 50Gy. However, the rate was lower at strong radiation higher than 600Gy at which $1^{st}$ leaf was not expanded fully and dead due to extreme overgrowth at 44 days after treatment (DAT). The highest value of panicle weight was observed at 50Gy (6.15g) and 100Gy (5.57g). On the other hand, the weight at high irradiated dose of 300Gy and 400Gy was decreased by about 55% compared to low dose (50 Gy). NDVI measurement also showed the highest value at 50 Gy as the growth progressed. SPAD was the highest at 400 Gy and showed positive correlation with irradiation dose except 0 Gy. Fv/Fm was high at 50 Gy up to 30 DAT and no difference between treatments was observed except for 400 Gy from 44 DAT. The plant height was the highest in 50Gy during the growing period and was higher in the order of 50Dy, 100Gy, 0Gy, 200Gy, 300Gy and 400Gy in 88 DAT. In this experiment, the optimal radiation dose for hormesis was 50Gy and 100Gy, and the optimal radiation dose for mutagenesis seems to be 400 Gy.

감시림프절 검사에는 $^{99m}Tc$-ASC, $^{99m}Tc$-Tin colloid, $^{99m}Tc$-HSA 등이 사용되었으나 공급 제한으로 간 스캔에 사용되고 있는 $^{99m}Tc$-phytate를 대체 방사성의약품으로 사용하고 있다. 이에 저자들은 phytate의 입자 크기 분포를 알아보고 200 nm 필터 사용유무에 따른 영상을 획득 분석하여 감시림프절 검사 시 필터 사용의 적절성을 판단하고자 하였다. Photal사의 ELS-8000 장비를 이용하여 phytate kit의 입자크기 분포를 측정 하였다. 동물 실험은 생후 12~15주령, 체중 250~300 g 암컷 백서를 사용하였으며, 전신 마취 후 앙와 위로 고정시켜 영상을 획득하였다. 비교군으로 여과시키지 않은 $^{99m}Tc$-phytate를 실험군으로는 200 nm 필터를 이용하여 여과시킨 $^{99m}Tc$-phytate를 백서의 발가락 사이에 피하주사 하였다. 6마리의 백서를 3~4일 간격으로 비교군과 대조군으로 그룹을 나누어 2회씩 실시 하였으며, 주사 후 1시간 지연영상을 얻은 후 서혜부에 관심영역을 설정하였으며 비정상적인 집적이 없는 부위를 선별하여 픽셀당 카운트를 얻었다. 세포 실험은 RAW 264.7 세포를 이용하여 비교군과 실험군에 $^{99m}Tc$-phytate를 넣어주고 30분 동안 배양시켜 감마카운터를 이용하여 각각의 분 당 카운트 값을 측정하였다. 이 값들은 SPSS 12.0 프로그램을 이용하여 통계 검정하였다. Phytate를 생리식염수에 용해시킨 후 측정 결과 평균 직경은 130~650 nm가 $85{\pm}5%$ 정도였으나 200 nm 필터를 이용하여 여과시킨 후의 입자 크기는 용매 내 phytate 입자의 농도가 너무 낮아 측정할 수 없었다. 획득한 영상을 분석한 결과 비교군에서는 $60.2{\pm}4.88$ count/pixel, 실험군에서는 $58.3{\pm}5.97$ count/pixel 값을 보였다. 세포 실험에서 실험군의 카운트 값은 $17,152{\pm}1,165$ cpm이고 비교군은 $16,908{\pm}1,075$ cpm을 보였다. 동물 실험과 마찬가지로 세포 실험에서도 통계적 차이는 보이지 않았다. 이번 실험을 통하여 phytate의 사이즈가 매우 분산적이며 균일하지 못 하다는 사실을 확인하였으며, 동물 실험과 세포실험을 통한 필터 사용의 적절성을 판단한 결과 phytate를 이용한 감시림프절 검사에서 필터를 사용하는 방법은 결과에 큰 영향을 미치지 않는다는 것을 확인하였다.

배경: 최근 레이저를 이용한 경심근 혈류 재건술(TMR)이 말기 협심증 환자에게 협심증이 개선에 효과가 있는 치료 방법으로 보고되고 있으나 여러 동물 실험 연구들에서는 상반되는 결과들이 발표되어 왔다. 본 연구에서는 돼지의 만성 심근 허혈 모델에서 국소 심근 혈류량의 측정을 통하여 TMR 후 심근 관류 개선 여부를 검증하고자 하였다. 대상 및 방법: 14마리의 돼지에서 좌회선지 관상동맥에 ameroid ring을 거치하여 만성 심근 허혈을 조성한 후 4주 경과시 각 7마리씩 대조군과 실험군으로 나누어 대조군에서는 개흉과 심낭내 유착 박리만을 시행하였고 실험군에서는 Ho:YAG 레이저를 이용하여 좌회선지 영역에 TMR을 시행하였다. 이후 다시 4주가 지난후 동물을 희생시키고 심장을 적출하여 각 수술 시마다 주사된 각각 다른 색의 착색 미세구를 이용, 국소 심근 혈류량을 측정하였다. 심근 절편 내의 미세구 함유량을 측정하여 회선지 영역과 심실 중격간의 혈류량 비를 비교함으로써 대주군과 실험군 사이의 혈류량 변화의 차이를 분석하였다. 결과: Ameroid ring 거치 4주 후 좌회선지 영역의 심근 혈류량은 심실 중격 혈류량의 46∼89%로 감소되었다. 8주 경과시의 좌회선지 영역 심근 혈류량은 대조군 4마리 중 3마리에서 4주 경과 시에 비해 유의하게 증가되었으며 증가 폭은 14∼18%였다. 실험군 6마리 중에서는 2마리에서만 유의한 증가가 관찰되었으며 증가 폭은 7∼34%였다. 결론: 돼지 만성 심근 허혈 모델에서 Ho:YAG 레이저를 이용한 TMR 시행 4주후 허혈 영역의 국소 심근 혈류량 증가는 대조군과 비교하여 큰 차이가 나지 않는 것으로 판단되었다. 그러나 통계적 유의성을 검증하기 위해서는 더 많은 수의 동물을 대상으로 한 연구가 후속되어야 할 것으로 사료된다.

In our society today, a variety of medical caring system, along with a scientific development in the area of oriental medical science plus national demand, has increased the augmentation and the opening of oriental wards and hospitals (Han Bang), which has come to create an additional requirement of nursing activity at oriental medicine wards should be different from that of the general wards or the same as the other. In view of this, various studies need to be made in this connection. The purpose of this study is to comprehend the number of nurses who want to work at oriental medicine wards and measure job satisfaction in nursing as compared with those working at general wards so as to provide basic materials for future assignment and supplementary training for the nurses. An attempt was made to contribute toward nursing administration on the one hand improving nursing training course on the other hand. A total of 72 nurses currently working at two oriental medicine hospitals available in Seoul and 82 general nurses were selected for this study using the questionaire from December 1993 to January 1994. An instrument for the study was based on the measurement of work satisfaction developed by Paula L. Stamps including 37 questions complemented by Kim for revision (1993) and 14 questions regarding general characteristics and oriental medicine wards. The instrument to test dependability showed Cronbach's=0.7711. The collected data have been processed by computer package SPSS. General characteristics of the two groups and the matters involved in oriental medicine wards were calculated into real figure and percentage an similarities between the two groups were analyzed by t-test and F-test according to the characteristics of variables. The comparative test on work satisfaction among the two groups including general characteristics and work factors were conducted by t-test and F-test. The major findings as a result of the study are as follows : 1. As general characteristics, age group of $26{\sim}30$ years are more than any segment of age. As to marital status, the number of those in single status is slightly higher than the married. Approximately 80% of them are graduates of nursing schools and nursing colleges. They are mostly in service for one to three years. There is no significant difference between the two groups. 2. The number of those who want to work at oriental medicine wards represents 40.3% against 58.4%, being in favor of general wards. 3. The reason for service at oriental medicine wards is that "there is room for potential research" which happened to rank first, followed by "easy job," "good working atmosphere" and "growing interest in oriental medicine." 4. Work satisfactions among nurses who work at oriental medicine wards prove greater than that of nurses who work at general wards. 5. Work satisfaction between the two groups by work factors is reflected with significant difference statistically on task requirement, interaction and doctor-nurse relationships. 6. The general charcateristics and the work satisfaction by work factors prove that there are significant difference in age, marital status, education and the period of work. They tend to be more satisfied with the work as they grow in age. Significant differneces are found in the work factors such as autonomy, adiministration and professional job in the relationship with doctor-nurse. As to marital status, the married are more satisfied than the unmarried. There are significant differneces in the factors respecting administration and doctor-nurse college graduates are highly satisfied with task requirement. However, satisfaction with the professional level has proven the highest degree for those having master degree. The period of work and satisfaction : There are significant differneces in task requirement, administration, interactions, professional level and doctor-nurse relationships. As a general rule, the degree of satisfactions is in proportion to the lengrh of service. The following conclusions are drawn based on the fndings mentioned above. Even though the work satisfaction of the nurse who work at oriental medicine ward is relatively high, it is desired that personal consultation be given as to disposition of nurses when they are assigned to oriental medicine wards. It is also recommended that lectures on oriental medicine be conducted through supplementary training and/or basic nursing course in order that they may be motivated for ingenious activities with an increasing sense of self-esteem which will eventually enhance positive changes for the patients who are in need of oriental medicine nursing and for the medical teams. In addition, joint reseaches involvingclinical care and education should be in constant process for unique and scientific development for those who are subject to oriental medicine nursing care.

최근 tactile sensor 를 사용하여 근육의 경도와 탄성도를 조사하는 방법이 저작근의 새로운 평가방법으로 제시되고 있다. 본 연구의 목적은 촉각센서를 이용하여 일정시간 껌씹기를 시행전, 중, 후의 저작근의 경도와 탄성도를 조사하여 향후 턱관절 장애 환자의 저작근 평가를 위한 기초자료를 확보하는 데 있다. 건강한 성인 8명을 대상으로 양측 전측두근(anterior temporalis), 하교근(inferior masseter)의 경도와 탄성도를 촉각센서 (Venustron II, Axion Co., Japan)를 이용하여 다음과 같이 측정하였다. 피검자들을 unit-chair에 바로 앉힌 상태에서 양측 교근 및 측두근 부위를 촉진을 통해 전 측두근(temporalis anterior), 하 교근(masseter inferior) 두 부위를 펜으로 표시하였다. 실험의 재현성을 위하여 투명한 종이에 ala-tragus line을 표시한 후 두 부위를 투명종이 위에 표시하였다. 편안한 상태에서 촉각센서를 사용하여 양측 하 교근 및 전 측두근의 경도와 탄성도를 측정한 후, 껌(Excellent Breath, Taiyo Co., Japan)을 양측으로 씹게 하여 1초당 2회의 속도로 씹게 하였다. 껌을 40분동안 저작하는 동안 10분, 20분, 30분, 40분에 양측 하 교근 및 전 측두근의 경도와 탄성도를 측정하였다. 그 후 껌을 뱉게 하고 하악의 안정위 상태에서 10분, 20분, 30분, 40분 후 양측하 교근 및 전 측두근의 경도와 탄성도를 각각 측정하였다. 측정치들을 반복측정 이원분산분석과 다중비교를 통하여 비교하였다. 실험결과 측두근과 교근을 비교 시 탄성도, 경도 모두 교근의 변화가 유의하게 크다. 또한 저작하면 서서히 경도는 증가하며 탄성도는 반대로 감소한다. 탄성도 및 경도는 저작 시 신속히 증가하나 저작 종료 후에는 탄성도만 신속히 회복되나 경도는 약 10분 이상의 일정시간이 지나야 회복된다. 이상의 결과들을 보아 임상적으로 좀 더 다양한 연구와 기초자료가 확보된다면, 저작근의 근육 상태를 평가하는데, 근육의 탄성도와 경도를 조사하는 tactile sensor system은 유익한 기기로서 활용될 수 있을 것이다.
