The purpose of this study was to develop and validate the Food frequency questionnaire (FFQ) for dietary studies of Koreans. One hundred and five food items for the Food frequency questionnaire were selected based on information of frequently consumed foods from National Nutrition Survey Reports and on raw data from a dietary survey on diabetic patients. Frequency of consumption was determined through nine categories ranging from more than three times a day to almost never to indicate how often the specified amount of each food item was consumed during the past month. Three portion sizes were given for each food item(small, medium or large) with respect to a stated medium portion. Seventy-three healthy women served for the validation study. They completed both the FFQ and a 3-day diet record. The FFQ estimate of mean nutrient intake was higher by 10-20% than that of the 3-days diet record and the Spearman correlation coefficients between the two methods ranged from 0.26 to 0.59 . The degree of agreement was from 36% to 38% when nutrients intake assessed by the FFQ and 3day diet record were classified within the same quintile. On the whole , the result of this study seemed to be in good agreement with other studies. Therefore the FFQ developed in this study is considered to be a reliable tool in assessing the dietary habits of Korean.

Cell mediated immunity is depressed following surgical procedure and the degree of immunosuppression is directly related to the magintude of the procedure, blood transfusion, and length of operation. So we would expect cardiac operations to be highly immunosuppressive, although little is konwn about their immunosuppressive effect. The nearly complete consumption of complement factors and decreased levels of IgM and IgG resulting in an impaired opsonizing capacity. Additionally, peripheral blood mononuclear cell counts including T-and B-lymphocytes and T-cell subsets are reduced. Depression of cell-mediated immunity following open-heart surgery is potentially detrimental because it could increase the susceptability of patients to viral and bacterial infection. We reviewed 20 patients after cardiac operation to search for changes in peripheral blood lymphocyte subsets. Lymphocyte subsets were measured by flow cytometer and the preoperative values of lymphocyte subsets were compared with those from the first, fourth, and seventh days after operation. After cardiac operation, total mumbers of T lymphocyte was severely depressed on the first postoperative day and returned to the preoperative level by the seventh day after operation. CD3, CD4, and CD8 lymphocytes were decreased on the first postoperative day and returned to the preoperative level by the seventh day also. There was four cases of wound infection and these patients had increased CD4 lympocyte and more decreased CD19 lymphocyte compared with the non-infected group. It is concluded from these data that cell-mediated immunity is significantly depressed for at least one week following open-heart surgery and this result was closely related to the postoperative infection.

This study investigates daily stock market anomalies in Chinese stock market, using nine most representative stock indices over an eleven year time period spanning from pre-financial crisis era to six years into the financial crisis. This research is the first to test the presence of the day of the week effect on stock returns in the Chinese stock exchanges during the financial crisis. We find that the day of week effects have been strongly significant in Chinese stock exchanges since 2004. However, unlike the previously found negative Monday effect and positive Friday effect in the U.S., Chinese stock market shows positive returns on Mondays and negative returns on Tuesdays. More importantly, the negative Tuesday effect is only significant after the inception of financial crisis. The results indicate a positive effect on Mondays and a negative effect on Thursdays. More importantly, we find a negative Tuesday effect during the financial crisis, which suggests a spillover of the Monday effect from the U.S. stock market. Our results shed some light on the degree of market efficiency in the largest emerging capital market in the world, and its increasingly close relationship with the U.S. capital market.

산림휴양은 야외에서 하기 때문에 날씨의 영향을 많이 받게 된다. 기온이 산림휴양에 미치는 영향은 연구되었으나 강수요인의 영향은 아직 연구되지 않았다. 이 논문은 산림휴양이 가장 많이 이루어지는 장소인 산악 국립공원의 탐방객수에 강수량과 강우일수가 영향을 미치는지를 파악하였다. 강수량과 강우일수를 설명변수로 설정한 산림휴양 수요함수의 추정 결과에 의하면 국립공원 탐방객수에 강우일수는 영향을 미치고 있다. 즉 일정 기간 중에 비나 눈이 온 날씨가 많았는지를 나타내는 강우일수는 탐방객수를 감소시키며 그 정도는 비탄력적이다. 한편 일정 기간 중에 비나 눈이 온 양을 나타내는 강수량은 통계적으로 유의하지 않고 계수부호가 예상과 다르게 나왔다. 이와 같은 결과에 근거하여 국립공원 관리를 포함하는 산림휴양 관리를 효율적으로 하기 위하여 사회경제적 변수뿐만 아니라 기상변수에 대한 체계적인 모니터링이 필요하다.

The purpose of this study was to assess the nutrition education and training needs as a basis for program planning for day care children. Nutrition achievement test developed by American National Dairy Council and Iowa state University was modified and used for measuring the level of basic knowledge of food and nutrition for day care children. The results of this study can be summarized as follows 1. Over 70% of mothers indicated their children had a certain degree of food behavior and feeding problems in terms of unbalanced food habit, irregular meal period. 2. Mean score for the nutrition achievement test for day care children was 9.3. 3. The nutrition achievement test score for children with high socio-economic status was significantly higher than those of children with middle and lower group. 4. Inspection of the difficulty difference indices showed that over the 50% of the children had more items that were easier in the content of physiological facts than in the food handling and social psychological aspects of foods.

The aim of this survey is to investigate the occupational musculoskeletal disease and stress levels of restaurant cooks and to provide a basic data of programs in order to prevent occupational diseases. A questionnaire survey was conducted on 220 subjects in Gangwon province. The results show that there was no significant difference in the degree of occupational musculoskeletal disease between male cooks and female cooks. However, western cuisine cooks were more likely to have a higher degree of occupational musculoskeletal disease than other cuisine cooks and showed a higher degree of occupational stress from work overload as well as irregular meal stresses. Cooks aged from 30 to 40 years showed a higher level of occupational musculoskeletal disease in the neck, shoulder, and hand/wrist compared to those in other age groups. The job tenure was related to the degree of musculoskeletal disease in knee. Additionally, the hours of working per day were statistically significantly related to musculoskeletal disease in the knee and to the occupational stress levels in irregular meals stress. The findings of this study suggest that it is essential to design customized education for cooks to lessen their occupational musculoskeletal diseases and stresses in order to ensure the health and safety of the culinary workers.

This study was investigation of the change of fine structure of hemp cellulose at different growing stages. The samples collected about every eight day were divided into seven groups based on plants height, then they were numbered from 1 to 7 in the order of their height. For this, the degree of crystallinity, orientation and crystallite size were measured by wide angle X-ray diffraction method. The results of this experiment were summerized as follows ; 1) The degree of crystallinity was increased by growth of hemp celtilose to be maximum in sample 5$\~$6. At this stage, the stability of crystals was showed in good states. In addition to, crystallinity index by Segal, Turley and area method showed same tendency as Ruland's. 2) The change of orientation was gradually increased by growth of hemp cellulose. This result was correlated with the degree of crystallinity. Therefore, the change of orientation depend on the degree of crystallinity. 3) On the other hand, the crystallite size was decreased by growth of hemp cellulose. But, increased after sample 4. By the way, crystallite size was interrelated with growth rate.

In this study, we conducted a comparative analysis of the effects of resuscitation after the re-application of mortar with much FA replacement on the degree of resuscitation. Results When NaOH was applied to the top of the mortar where 90% of FA was replaced, and maintained for 24 hours, the degree of resuscitation at $40^{\circ}C$ was completely improved. However, when medium curing was carried out, it showed a higher degree of compression than water or lapping curing at 10 MPa in 28 days. The degree of resuscitation on the 28th day was revived from around 10% of the normal level to about 20~30%, and it was analyzed that it was difficult to achieve the OPC reduction by any method.
