The experiment was carried out to investigate the adaptability of freezing process with thirteen strawberry varieties cultivated in Suwon, Pusan and Chunju area. Six of these were local varieties and the others were varieties imported from the United States of America. Each strawberries variety was analysed chemically to determine value of soluble solids, acidity (calculated as citric acid) and deepness of color. Frozen products were prepared by a general method adding sugar to $28^{\circ}\;Brix$. Local varieties Haengok, Bokuh, Keikwan and Daehak No. 1 were not suitable for making into frozen products because of excessive white color in their centers. Blakemore, an imported variety, was best as to color. Chemical analysis showed that imported varieties have higher acidity, and lower content of soluble solids. In a sensory test conducted by fifteen members of Agriculture and Fishery Development Corporation, deeper colors of strawberries did not receive a generally favorable response, and it was found that strawberry colors favored by the America were not liked by Korean well.

This study analyzed the relationship between mother-child communication and the self-concept of young children. The subjects were 93 three-, four-, and five-year-old kindergarten children and their mothers in the city of Chunju. The self-concept test, mother-child communication inventory for children and the mother-child communication questionnaire for mothers were used. The data were analyzed by T-test, General Linear Models analysis, Duncan's Multiple Range test, Paired T-test, and Pearson's correlation coefficient. The major findings were that (1) the children perceived mother-child communication more intensively than mothers, (2) the more positive communication the children perceived they had with their mothers, the higher their self-concept, (3) the self-concept of 5-year-olds was more highly correlated with perception about mother-child communication than the self-concept of the younger children, and (4) boys' self-concept was more highly correlated with perceived mother-child communication than girls'.

2,2'-bipyridyl crown ether에 관한 allosteric 효과를 분자진동연구방법을 사용하여 연구하였는데, 방법으로는 mass-weighted-cartesian 좌표방법을 사용하였다. Crown ether의 pore opening 운동에 관여하는 모드로는 235, 234, 188 그리고 178cm$^{-1}$에 해당되는 파수가 얻어졌고, biphenyl축을 통한 회전운동이 crown ether에 영향을 미치는 rotational vibration 운동은 168, 104 그리고 67cm$^{-1}$에서 파수가 얻어졌다. 특히 178cm$^{-1}$의 모드는 allosteric효과를 가장 많이 포함한 것으로 생각되어 진다.

This study aims to analyze the parking demand in general hospitals in Chunju. The survey is done to examine the capacity of parking, the time of parking, the frequency of parking, and the actual condition of parking space. As a results of analysis, the conclusion was derived that the parking space is not satisfactory compared to the desired level. Consequently, this study aims to represent the improved parking based on characteristics of parking systems and the practical uses of the parking space in general hospitals.

In order to estimation the optimum PID parameter of the turbine speed controller, the response cure of the object plant was compared with the reference pattern and then the magnitude peak value error and peak time error was calculated. With the calculated errors as input into the Fuzzy inference Method was introduced to propose the tuning method for each parameter. And the computer simulation was performed with the above Fuzzy inference method in which the Chunju hydro power plant turbine governor system was used as a model. This Study also aims to develop the exclusive tuner for govenor using industrial computer.

Deep learning models require high computing power due to a substantial amount of computation. It is difficult to use them in devices with limited computing environments, such as coastal surveillance equipments. In this study, a lightweight model is constructed by analyzing the weight changes of the convolutional layers during the training process based on MobileNet and then pruning the layers that affects the model less. The performance comparison results show that the lightweight model maintains performance while reducing computational load, parameters, model size, and data processing speed. As a result of this study, an effective pruning method for constructing lightweight deep learning models and the possibility of using equipment resources efficiently through lightweight models in limited computing environments such as coastal surveillance equipments are presented.

유동층 연소로에서 압력 요동의 통계적 처리 방법을 이용하여 충전물질의 유동층 거동에 대한 영향을 분석하였다. 실험은 내경이 6.7cm인 유동화 장치에서 수행하였고, 실험변수는 입자크기 및 분포, 유동화가스, 유동층의 aspect ratio(L/D), 충전물 등이다. 충전물질은 스크린 충전물질을 사용하였고, 압력 요동 특성은 차압 전달기로 측정하였다. 측정 압력 요동 특성치는 평균값과 표준편차, power spectral밀도 합수의 주진동수 등이다. 압력요동의 표준 편차는 압력 측정 tap의 반경 방향에 거의 영향을 받지 않았으며, 압력 측정 tap의 축방향에서는 충전물이 없는 경우 가스분산판 약 4.5cm 이상에서는 거의 일정하다. 충전물의 크기가 증가할수록 주진동수는 감소하는 경향이 나타났으며, 충전물의 양이 10% 부근에서 주진동수가 가장 큰 변화값을 나타내었다. 압력 요동의 표준 편차는 유동층 연소로의 거동을 해석하고 유동화 현상을 설명하는데 효과적이며, 압력 요동의 특성들은 충전물질에 많은 영향을 받았다.

We had studied the relationship between the difference of average temperature of Meridian points of left and right face taken by DITI on 1st hospital day and the improvement degree of facial mucles on the patients of Bell's palsy after 10 days treatment. The clinical data and thermographic imaging were analyzed on the 42 cases of Bell's palsy who were treated in the Chunju Oriental Medicine Hospital of Wonkwang University from May to November 1999, and we selected 29 cases within 10 day-onset and the following results were obtained. 1. Assuming the difference of the muscle scores' sums very attending day from after 10 days treatment is improvement degree, and presuming the improvement degree is y, and the mean difference of average temperature between normal and abnormal facial side is x, we can infer the equation of the first degree as following [ y = 2.62 + 2.16 x ]. 2. This means that the higher temperature of nerve falsy side than normal side, the better consequence of treatment we can obtain.

This study has been conducted to investigate the amount of residual sulfur dioxide for herbal medicines of 30 species which are purchased in 13 different regions (Bonghwa, Busan, Chunju, Jecheun, Kwangiu, Keumsan, Seoul, Taeku, Cheungdu, Xian, Beijing, Tokyo and Osaka). The sulfur dioxide residues were determined in the collected 386 samples by the modified Monier-Williams method. The residues of sulfur dioxide in 386 samples ranged from ND (under detection limit) to 2808 ppm. The sulfur dioxide in Cassiae Semon, Cinnamomi Ramulus, Cervi Cornu, Hoelen, Crataegi Fructus, Artemisiae Argyi Herba, Scolopendrae Corpus, Schizandrae Fructus and Cyperi Rhizoma were detected under the detection limit regardless of the collected regions. The sulfur dioxide residues in herbal medicines collected in domestic regions were relatively lower than those in foreign regions. There are no standards for sulfur dioxide residual limits of herbal medicines in Korea. This results will provide the scientific basis for the standardization of sulfur dioxide residues in Korea Pharmacopoeia.

We have Investigated dielectric properties depending on bias voltage in organic lightemitting diodes using 8-hydroxyquinoline aluminum($Alq_3$) as an electron transport and emissive material. We analyzed the dielectric properties of organic light emitting diodes using impedance characteristics measurement by the auto-balancing bridge technique and equivalent cirrcuit of ITO/$Alq_3$/Al. Impedance characteristics was measured complex impedance Z and phase ${\theta}$ in the frequency range of 40 [Hz] to $10^8$ [Hz]. We obtained complex electrical conductivity, dielectric constant, and loss tangent ($tan{\delta}$) of the device at room temperature. From these analyses, we are able to interpret a conduction mechanism and dielectric properties contributed by an interfacial and orientational polarization.
