To illuminate the state and countermeasure of soilless cultural production and marketing in Korea, the survey of soilless cultural production through Agricultural Agent Center, questionnaire, field investigation, and literature analysis were performed. Soilless cultural farm-houses were 82 and area was 11.1 ㏊ on September, 1992. But its area of chief producing district and kind of crops are rapidly being changed. To solve the problems of soilless culture in Korea; old age and low education of farmers, small cultural area, financial difficulty, none standardization of facilities material and none specialization of varieties for soilless culture, it must be actively put in practice for soilless cultural improvement of Korea that the technical education strengthenning, financial support by government, standardization of facilities material and variety specialization. Poor sales network and policy, poor marketing intelligence network and activities, negligent selection and packing of products become the major cause of soilless culture's failure. Therefore, spontaneous sales network organization, marketing support of Horticultural Cooperative Association and Agricultural Cooperative Association, elevation of marketing intelligence power, and continuous effort of farmer for successful selection and packing of products are essential factors for soilless cultural development of Korea. Soilless culture is a royal road to change from primary agriculture to secondary agriculture for agricultural innovation, but there are many problems in this system and it is difficult to solve that problems by only farmer's effort. Therefore, not only farmer but also researcher, scholar, related groups and government concentrate their effort on solution of soilless cultural problems.

Authors have conducted a study on 442 infants participated in Kyungpook regional wellbaby contest, held in 1982. After through investigation of several parameters including physical growth (body weight, height, chest and head circumferences), nutritional status (Kaup index, serum protein, hematocrit and signs of vitamin C deficiency), and feeding history, along with comparing this with data obtaind from past 5 years (1976-1980), the following results were obtained. Comparing their body weight, height, chest and head circumferences with Korean children's growth standard(K.S.) and Japanese children's growth standard(J.S.), their body weight were superior to those of K.S(2.11-3.19kg) and J.S(1.25-2.25kg), their height superior to those of K.S(4.29-6.75cm) and J.S(2.46-2.73cm) but no remarkable diference between these data and those obtained from past 5 years. Triceps skin fold thickness and scapular thickness were superior to those of Hong(0.4-1.93mm,2.29-2.83mm), the arm circumference were superior to those of Hong(2.19-2.77mm), too. But no remarkable difference between these data and those obtained from past 5 years were found. Total mean serum protein was 7.0gm% in male infants and 7.08gm% in female infants. Kaup index was over 20 in 7.8% in male infants and 6.3% in female infants. Compared to past 5 years, obesity was found less frequently. Breast milk feeding was the most common form of the infant feeding comparing 50.2%, followed by mixed feeding 29.8%, and bottle feeding in 20%. Weaning was started between 4-6 months of age in 56.6% of infants and the vast majority within 12 months of age (98.9%) About 5% of those infants showed anemia, using the cirteria of anemia as being hematocrit less than 33%. They were found in 3.4% of infants with iron-supplemented group, and 5.4% of infants without iron supplementation. In 12.7% of the infants, there were signs of the vitamin D deficiency including Harrison's groove, rachitic rosary, and pigeon chest. They were found in 10% of infants with vitamin D supplementation and 13.6% of infants without supplementation. Compared to past 5 years, anemia and vitamin D deficiency were found less frequently.

The purpose of this study was to investigate quantity food production practices in foodservices by analysing the menus of April, 1996. The questionnaire was developed and responded to by 96 dietitians in Sangju, Munkyung, Gumee, Kimchun, and Andong during November, 1996. The survey was performed by simple random samplings. The results were as follows; 1. Hospitals and industry served food for thirty days and schools for twenty days. Kimchi was a select-menu for hospitals and one side dish for industry and schools. The type of menu was a single use menu which consisted of cooked rice, soups and three side dishes. 2. The most frequently used ingredients were green onions, rice, carrots, onions, Korean radish roots, pork, eggs, glutinous rice, and milk. Kimchis were served most frequently in all food-services and cooked rices and soups were next. 3. The age of most of the respondents was 26 to 30. 54.2% of subjects were junior college graduates and 77.1% were single. Fifty-seven point three percent of the dietitians lived with family, relatives, or friends. 87.5% of the dietitians had been working for 1 to 5 years. 4. Most foodservices were self-operated. The number of meals served was determined by meal coupon counting in hospitals(37.5%), meal board counting in industry(29.2%), and attendance card counting in schools(41.1%). The cost of sales per meal was approximately 2,450 won in hospitals and was approximately 1,100 won in industry and schools. The average number of days per menu cycle was 7.4 in hospitals, 10.3 in industry and 25.5 in schools. Hospitals, industry, and schools held about 118, 265, and 263 recipes, respectively. The average number of dietitians was 2.6 in hospitals and 1.0 in industry and schools. Except for the number of recipes, the general practices of foodservices were significantly different(P<0.05). 5. In the general quantity food production, food and seasonings measuring was hardly done. The percentage of foodservices using chemical seasonings was higher in hospitals and industry than in schools. The most important concern was taste. Registered cooks were employed in 75% of schools but only 50.0% in hospitals and 20.8% in industry. Most of the dietitians responded that their cooks skill was not bad. The education of unregistered cooks was performed once or two times a month in hospitals and industry, and in schools performed everyday. The problem when educating cooks was the lack of cooking skill of the dietitians in schools, and the lack of time in hospitals, and the negative attitude toward education in industry. The method for improving cooking in all foodservices was OJT, or the extension of education facilities and the development and dissemination of standard recipes. The frequency of throwing away leftovers was higher in hospitals. But in industry, the frequency of saving leftovers was higher. 6. Though all foodservices have standard recipes, the number that used them was low. Another problem is that standard recipes resulted in leftovers. The inconveniences of using standard recipes were the difficulty of applying standard recipes to various numbers of customers the complication of use, or facility insufficiency.

The purpose of this study is to develop an air-passing soundproofing panel with more improved structure to reduce the CO2 emission and installation cost. To reduce the emission of CO2 ; it is suggested to choose low CO2 emission material relative to the aluminum and to reduce the materials by developing a specially designed air-passing soundproofing panel structure. First of all, we performed the flow analysis to predict the wind pressure according to the open angle of the air-passing soundproofing panel and the noise level analysis at the receiver point. To verify the simulation, a prototype of the soundproofing panel was made. The flow test in the wind tunnel and load test were performed. The economic evaluation for the installation of the air-passing soundproofing panel was performed and specifications of the installation was prepared. As the results of this research, it was verified that the wind load was reduced about 40% to that of the conventional one at 25m/s wind speed in the wind tunnel test. By applying the 4m span soundproofing wall with air-passing soundproofing panel and under the cost of 250 thousand won/m2 instead of the conventional 2m span panel, the installation cost will always be lowered than the conventional one in the combination of (60:40~50:50) conventional to air-passing soundproofing panel from the economic evaluation. The 20% reduction of CO2 was found by changing the 50% of aluminum soundproof panel to air-passing soundproofing panel.

Objective. Productivity loss was compared by 3-stage of disease activity and associations between higher disease activity and high productivity loss were identified. Methods. Data were extracted from Rheumatoid Arthritis (RA) Patient-reported Outcomes Research, which enrolled 2,000 RA patients (>20-year) on disease-modifying-antirheumatic-drugs (DMARDs) (≥ 6-month) from December 2012 to June 2013. This included 1,457 RA patients with the disease activity score (DAS-28-ESR) in their medical charts. Productivity loss in time and indirect cost was estimated using The World Health Organization Health and Work Performance Questionnaire (HPQ). Baseline characteristics and productivity loss outcomes were compared according to DAS-28-ESR groups. Results. 84.4% were females, 54.2% had low DAS-28-ESR (<3.2), and 38.2% and 7.6% had moderate (3.2∼5.1) and high DAS-28-ESR (>5.1). Patients with moderate to high DAS-28-ESR had higher lost productivity time (LPT) and monthly costs of LPT than those with low DAS-28-ESR (time in hours: 110.0±58.4 vs. 132.4±57.2 vs. 71.5±52.0, p<0.0001; monthly costs of LPT in 1,000 Korean won: 1,097±607 vs. 1,302±554 vs. 741±531, p<0.0001). Multiple regression analyses revealed significant associations with high LPT in high (adjusted odds ratio [OR]=3.87, 95% confidence interval [CI]: 2.18∼6.87) and moderate DAS-28-ESR (adjusted OR=1.88, 95% CI: 1.41∼2.52) compared to low DAS-28-ESR. In addition, positive associations with high monthly costs of LPT were observed in high (adjusted OR=3.45, 95% CI: 1.98∼5.99) and moderate DAS-28-ESR (adjusted OR=1.93, 95% CI: 1.43∼2.54) compared to low DAS-28-ESR. Conclusion. Timely therapeutic strategies should be taken into consideration given that the RA patients with moderate to high DAS-28-ESR showed strong associations with high productivity loss for effective management of RA.
