당밀의 첨가가 오적산박 사일리지의 품질 및 한국재래산양에 대한 기호성을 조사하기 위하여 두가지 실험을 수행하였다. 실험 I에서는 오적산박에 당밀을 0, 0.5 및 1.0% 첨가하여 사일리지를 제조하였고, 실험 II에서는 오적산박 사일리지의 기호성을 조사하기 위하여 9두의 우리나라 재래산양을 공시하여 당밀 첨가수준별 및 옥수수 사일리지와의 섭취량을 비교하였다. 실험 I에서는 당밀의 첨가에 의하여 젖산함량이 유의하게 많아지고, pH와 낙산은 낮게 나타났다. 당밀의 첨가로 사일리지액의 유산균배지 배양시험에 있어 총균수는 증가하였고, 곰팡이 균주는 감소하였다. 그리고 당밀의 첨가에 따라 체외 건물 소실율이 증가하였다. 실험 II에서는 당밀의 첨가가 사일리지 건물섭취량에는 유의한 영향을 미치지 못 하였으며, 오적산박 사일리지는 옥수수 사일리지에 비하여 기호성이 좋았다. 결론적으로 오적산박 사일리지에 대한 당밀의 첨가수준은 1% 정도면 품질을 향상시킬 수 있으며, 체외 소화율도 개선할 수 있다고 생각된다.

핵의학(nuclear medicine )이 란 방사성 및 안정 핵종의 동위원소표지 화합물을 인체에 투여하여, 관심장기의 형태 및 기능을 평가하여 해부학적 또는 생리학적 상태를 진단, 치료하는 의학의 전문 분야이다. 핵의학에 이용되던 방사성 핵종은 1960년대 까지만 해도 $^{131}$ I이 주였으나 1970년대 부터는 $^{99}$Mo -$^{99m}$ Tc 발생기와 $^{99m}$ TC으로 표지된 방사성의 약품이 활발히 이용되면서 $^{131}$ I을 대신하게 되었다. 원자로-생산핵종들의 특성은 중성자가 과잉이어 붕괴시 배타입자를 방출하는 점으로, 이것이 각종 질병의 치료에 이용되고 있다. 특히 각종 표시 화합물의 성질을 이용하여 원하는 부위에 방사선을 집중시킬 수 있음이 외부조사보다 유리한 점이다. 방사성핵종을 이용한 악성종양의 치료에 가장 성공적인 것은 분화된 갑상선 암환자에서 $^{131}$ I을 사용한 것이며, 갈색세포종 등에 $^{131}$ I-MIBG도 효과적이다. 악성종양의 골전이 치료에 베타선을 방출하는$^{32}$P, $^{186}$ Re, $^{153}$ Sm 등이 이용되었다. 종양의 동맥에 주입하여 세동맥이나 모세혈관에 걸리는 기름, 교진 또는 입자에 의한 치료에 $^{131}$ I-lipiodol, ethiodol, $^{32}$P 또는$^{90}$ Y흡사 ceramic resin 미소구 $^{166}$ Ho 유산중합체 미소구 등이 이용된다. $^{166}$ Ho, $^{198}$ Au, $^{32}$P, $^{90}$ Y, $^{169}$ Er, $^{186}$ Rc, $^{131}$ I, $^{211}$ At 등 의 방사성 핵종의 교질, 미소구 또는 단세포군 항체표지 형태로 직접 종양내 또는 공동이나 체강에 투여하는 치료법이 있다. 류마치스 관절염의 슬관절에 $^{165}$ Dy colloid를 주사하는 $^{166}$ Ho-MAA도 활발히 이용되고 있다.

The purpose of this study was to propose an effective field test for assessing the cardiovascular endurance of soccer players by comparing the shuttle run test and the Yo-Yo intermittent recovery test (Yo-Yo test), which are representative of the aerobic exercise performance test, with the VO2max and other sprint tests. The shuttle run test requires the subject to run continuously without a break interval, while the Yo-Yo test has a break interval, so that they run with the recovery period. Therefore, the Yo-Yo test can be used as an effective field test for evaluating the cardiopulmonary function considering the characteristics of the soccer players of intermittent training.

This study examined the Presence experience, resulting effects, and re-viewing intentions of visitors to experiential exhibition content. For this purpose a survey was conducted targeting 246 visitors to experiential exhibition content based on Hyecho's travel story and SilkRoad cultural heritage. As a result of the survey, understanding and interest in the content material and similar exhibition viewing experience did not affect Presence experience. In addition the higher the Presence experience of exhibition content, the greater the awareness and emotion that is the effect of Presence. And among the effects of Presence, emotion had a positive effect on revisiting intentions. Therefore, it was confirmed that future experiential exhibition contents require planning, production, and exhibition that allow users to experience Presence.

This study was conducted to create a digital archive for local cultural contents compiled from the records of westerners who stayed in Korea during the Enlightenment Period of Chosun. The compiled information were gathered from 22 records, and 10 main subjects, 40 sub-subjects and 239 mini-subjects were derived through the subject classification scheme. Item analysis was conducted through 38 metadata and input data types were classified and databased in Excel. Finally, a web-based digital archiving system was developed for searching and providing information through various access points. Suggestions for future research were made to expand archive contents through continuous excavation of westerners' records, to build an integrated information system of Korean digital archives incorporating individual archive systems, to develop standardization of classification schemes and a multidimensional classification system considering facet structure in cultural heritage areas, to keep consistency of contents through standardization of metadata format, and to build ontology using semantic search functions and data mining functions.

In order to investigate the method for extension of shelf-life of Kimchi, the effect of low temperature heating and addition of mustard oil on pH and total acidity of Kimchi during storage at $15^{\circ}C$ were studied. Mustard oil was found to have the antimicrobial effect on the major lactic acid bacteria of Kimchi such as Lactobacillus plantarum, Lactobacillus brevis, Leuconostoc mesenteroides and Pediococcus cerevisiae, Addition of 200p.p.m. mustard oil, 0.1% mustard powder and 0.01% $H_2O_2$ to Kimchi effectively reduced the fermentation rate of Kimchi. Low temperature heating of salted cabbage and addition of 200p·p.m. mustard oil and 0.01% $H_2O_2$ to seasonings extented the time reaching optimum ripening of Kimchi about 2.5 times longer than control. Combination of low temperature heating, addition of mustard oil and $H_2O_2$ to seasonings and post low temperature heating delayed fermentation time Kimchi about 5 times longer than control after 15 days storage at $15^{\circ}C$.

To investigate the effects of short-term treatment with tri-n-butyltin chloride (TBTCl) and bisphenol A (BPA) on the reproduction of striped field mice, the mice were intramuscularly injected with TBTCl or BPA immediately before the reproductive season and examined in the reproductive season after keeping them for 4 months. As a result, there were no differences between the control and the compound-treated groups regarding body weight in both sexes, the residual levels of the compounds in the adult males, and the gonadosomatic index (GSI) and the histological structures with LM and EM of the testes and epididymides in both the adult and young males. The infant mortality and abortion rate, however, were high in the TBTCl-treated groups and BPA-treated groups respectively, compared to the control group. Conclusively, it was suggested that short-term treatment with TBTCl or BPA in mice in the non-reproductive season might have inhibited the development of the uterine embryos or fetuses, although it did not induce accumulations of these compounds or affect the reproductive organs of adult and young (F1) males.

The purpose of this study was to investigate the effects of Pilates exercises on the improvement of blood pressure and respiratory function. 36 subjects which were randomly divided into Pilates exercises group(n=18) and control group(n=18). Subjects in the Pilates exercises group were regularly participated in Pilates exercise program for 8 weeks. We were measured the blood pressure and respiratory function such as blood pressure, VO2max, METs, and Anaerobic threshold at before and after the experiment. After 8 weeks, in Pilate exercises group, there were significant improvement on blood pressure and respiratory function except the diastolic blood pressure. And subjects participated in Pilates exercise group were significantly improved compared to control group on systolic blood pressure, VO2max, METs, and Anaerobic threshold. But in control group, there were no significant differences. In conclusion, regular participation in Pilates exercises improved the blood pressure and respiratory function. These results suggest that Pilates exercise is the method that replace aerobic exercise.

In this study, the normal group and possible sarcopenia(PS) group were divided by the criteria for sarcopenia diagnostic based on the 7th period data of the National Health and Nutrition Examination Survey. An independent t-test and logistic regression was performed for the difference between the two groups. As a result, the PS group was older, and height, weight, and BMI were all lower. The waist circumference was significantly lower in men but significantly higher in women. According to the quality of life by domain, the frequency of impairment in daily activities in exercise capacity was 8.28 fold in men and 15.52 fold in women. In addition, aerobic exercise regularity was 19% and 26% lower in the PS, and strength exercise regularity was practiced was 52% and 43% lower.
