In this study, we examined how the United States, Chinese, and Japanese viewers perceive the morality of the main characters in the family drama 'Take Care of Mom' and the influence of the perceived morality has on drama enjoyment and quality evaluation. Results show that the viewers from all three countries evaluated 'Hoonjae' favorably and evaluated selfish older brother, 'Hyung Kyu', unfavorably. This means there are common norms that exist in all three countries for judging the good and evil in a drama. However, the main female characters that played opposing characteristics were evaluated differently from all three countries. This is because the relationship between parents and children, and the role of mother and woman were perceived differently from each country. These results support the argument that consumption of drama may differ by viewer's cultural background. Additionally, the research hypothesis that 'moral evaluation of major characters will influence the drama enjoyment and evaluation of the drama quality' was not supported in China and Japan, and was only supported by the U.S. viewers.

This study was a descriptive correlational study investigating the mediating effects of resilience in the relationship between depression and rehabilitation motivation in middle-aged stroke patients. There was a total of 185 middle-aged patients aged 40 to 64 years, who were diagnosed with stroke at a university hospital and rehabilitated at three local hospitals located in S city and four hospitals in U city. The data were collected using a self-reported questionnaire between the 1st and 31st of December in 2016. The data were analyzed using t-test, ANOVA, Pearson's correlation coefficient, and step-wise causal method using SPSS/WIN 22.0 statistical program. To test the statistical significance of the mediation effect, PROCESS and bootstrapping were used. The mean age of the subjects were $56.26{\pm}6.37$ years. There were 70.3% male subjects, an average depression level was $21.21{\pm}7.09$, an average resilience was $25.52{\pm}9.63$, and rehabilitation motivation was $47.44{\pm}5.87$. Depression was negatively related to resilience and rehabilitation motivation. However, resilience and rehabilitation motivation have a static correlation. These results confirmed that resilience appears to be a complete mediating effect in the relationship between depression and rehabilitation motivation. Therefore, it is important to develop a resilience enhancement program to improve the motivation of rehabilitation for stroke patients.

Objective : The purpose of this study was to assess the complications, duration of admission, cost effectiveness, radiologic stabilization of the anterior cervical bone fusion in the treatment of cervical disc disease with and without plating. Materials and Methods : Fifty-two surgically treated patients for cervical disc disease were reviewed. Group I consisted of consecutive treated patients with iliac auto-bone graft without instrumentation after anterior cervical discectomy. Group II consisted of consecutive treated patients with iliac autologous-bone graft with CASPER cervical plate fixations. Radiologic fusion was decided when loss of end plate boundary between graft bone and vertebral body and immobile, maintenance of the disc space were evident on simple dynamic plain films. The patients were discharged after the stabilization of cervical motion by films was of tained. These groups were analysed multiple variably with Mann-Whitney U-test. Results : Group I consisted of 18 patients, group II consisted of 34 patients. Mean age was $49.0{\pm}8.1years$, mean duration of admission was $17.27{\pm}10.51days$, mean costs for treatment was $1,970,000{\pm}475,000won$. In group I, mean age was 47.7(34-60) years, 16 patients had undergo on one-level operation, 2-patients had undergo on two-level operation, mean duration of admission was $28.7{\pm}10.4days$, mean costs for treatment was $2,194,473{\pm}561,639won$. The periods of stabilization was $6.6{\pm}3.36weeks$ on radiologic study. Mean periods of out patient follow up was 16.8(6-64) weeks after discharge. Mean period of radiologic follow up was 17.3(4-6) weeks after surgical operation. In group II, mean age was 49.7(37-62) years and 18 patients one-level operation, 14- patients had undergo on two-level operation and 2-patients three-level operation. Mean duration of admission was $11.24{\pm}3.29days$, mean costs for treatment was $1,850,823{\pm}389,372won$. The periods of stabilization was $5.88{\pm}7.07weeks$ on radiologic study. Mean period of out patients follow up was 16.7(4-60) weeks after discharge. Mean period of radiologic follow up was 12.4(3-52) weeks after surgical operation. The duration of admission showed statistical significance in Group II but other items showed no significant difference between two groups. Conclusions : The more economic, early life return and effective method of cervical disc disease in our series were evident in patients who had undergone, iliac bone graft and plate fixations after anterior discectomy.

The influence of normal late pregnancy on insulin action and insulin secretion was studied in the Sprague-Dawley female rats. On 20th day after mating, intravenous glucose tolerance test(IVGTT) was performed in non pregnant control and pregnant rats. As results of IVGTT, glucose disappearance rate was not significantly different in both groups, but secretory response of insulin was significantly(p<0.05) increased in pregnant rat. And the ratio of insulin/glucose was significantly higher in pregnant rats, which means existence of insulin resistance. These insulin resistance was overcomed by increased secretory response of pancreatic insulin. Insulinogenic index(${\Delta}$ insulin/glucose - 5 min) was highly significantly (r=0.62, p<0.01) correlated with progesterone concentration. Glycogen level and amounts of $^{14}C$-glucose incorporated into glycogen after IVGTT were significantly(p<0.05) decreased in the liver, but were not changed significantly in soleus. Glycogen synthase activity of soleus and liver was not differ significantly in the both groups. Insulin binding at varying concentrations of insulin to crude membrane of pregnant liver was not significantly different from control. In conclusions, although these pregnant rats were normal glucose tolerance due to increased secretory response of insulin, that was correlated with progesterone concentration, pregnant rat had insulin resistance. The mechanisms of insulin resistance were not related to defect of insulin binding phase and glycogen synthase, but suggest pre-receptor and/or postreceptor phase.

Estimates of genetic gain (in volume growth) and diversity (expressed as status number, $N_s$) were determined in a clonal seed orchard of Pinus koraiensis. The genetic thinning was based on clonal breeding values (represented by general combining ability) obtained from progeny tests, clonal fertility estimated by strobilus production, and clonal size variation determined by the ramet numbers per clone. Parental GCA values for volume growth were calculated, based on height and diameter at breast height measured from field trials. Clonal fertility was estimated from the assessments of strobilus production over twelve years from 1991 to 2003, and used for the calculation of status number. There are 179 clones and 5,268 ramets in 12ha area of P. koraiensis clonal seed orchard. Genetic gain and diversity estimates were determined under assumptions of 30% pollen contamination and inferior genetic value of contaminating pollen. Genetic gain increased as thinning rates were set from 10% to 60%. However, for the higher thinning intensities, the increase of genetic gain was not remarkable. Genetic thinning by means of truncation selection resulted in a greater genetic gain but a large decrease in status number. Status number was represented around 40 clones for 10% through 60% thinning intensities, but for the higher thinning intensities, it was a bit fluctuated. Based on the present results, it could be concluded that thinning rate should not be stronger than 60% to optimize genetic gain while conserving genetic diversity. Consequently 50% or 60% thinning rate might be appropriate for genetic thinning in the clonal seed orchard of P. koraiensis. The effect of pollen contamination on the genetic gain and the consequence of genetic thinning for seed production in the clonal seed orchard, and seed orchard management scheme were also discussed.

Thermal mixing by steam jets in a pool is dominantly influenced by a turbulent water jet generated by the condensing steam jets, and the proper prediction of this turbulent jet behavior is critical for the pool mixing analysis. A turbulent jet flow induced by a steam jet discharged through a vertical upward single hole into a subcooled water pool was subjected to computational fluid dynamics (CFD) analysis. Based on the small-scale test data derived under a horizontal steam discharging condition, this analysis was performed to validate a CFD method of analysis previously developed for condensing jet-induced pool mixing phenomena. In previous validation work, the CFD results and the test data for a limited range of radial and axial directions were compared in terms of profiles of the turbulent jet velocity and temperature. Furthermore, the behavior of the turbulent jet induced by the steam jet through a horizontal single hole in a subcooled water pool failed to show the exact axisymmetric flow pattern with regards to an overall pool mixing, whereas the CFD analysis was done with an axisymmetric grid model. Therefore, another new small-scale test was conducted under a vertical upward steam discharging condition. The purpose of this test was to generate the velocity and temperature profiles of the turbulent jet by expanding the measurement ranges from the jet center to a location at about 5% of $U_m$ and 10 cm to 30 cm from the exit of the discharge nozzle. The results of the new CFD analysis show that the recommended CFD model of the high turbulent intensity of 40% for the turbulent jet and the fine mesh grid model can accurately predict the test results within an error rate of about 10%. In this work, the turbulent jet model, which is used to simply predict the temperature and velocity profiles along the axial and radial directions by means of the empirical correlations and Tollmien's theory was improved on the basis of the new test data. The results validate the CFD model of analysis. Furthermore, the turbulent jet model developed in this study can be used to analyze pool thermal mixing when an ellipsoidal steam jet is discharged under a high steam mass flux in a subcooled water pool.

1. 버섯종균 개선 버섯의 품질과 수량을 좌우하는 주요 요인은 종균의 활력이다. 그러나 라오스에서는 종균의 활력이 낮아 조그마한 100cc 병에 배양완성하는데 14일이 소요되는 등 볍씨종균의 균사생장과 균사밀도가 매우 낮음을 확인하였다. 따라서 100cc 병을 1000cc 비닐봉지로 개선하여 입봉하는데 소요되는 시간을 10배로 단축 개선하였다. 또한 곡립종균을 액체종균으로 대처한 결과 균사생장속도가 2배가 빨랐으며 작업속도가 4배가 빨라졌다. 2. 버섯배지제조 방법 개선 미세하고 건조한 톱밥에 수분을 첨가하는데 50%이하의 수분함량을 유지함으로서 균사가 표면에만 자라고 있는 것을 확인하고 버섯 배지제조 시 물리성을 개선하기 위하여 볏짚을 잘게 잘라 10%~100%까지 혼합하는 실험을 실시하였다. 그 결과 톱밥 50%에 볏짚 50% 혼합하는 것이 균사생장 속도와 밀도가 좋았다. 또한 왕겨도 30%정도 혼합한 배지처리에서 가장 좋았다. 또한 수분함량도 65%로 향상하여 혼합하도록 지도하였다. 3. 버섯배지살균 방법 개선 라오스에서는 왕겨를 태워 살균을 실시하고 있다. 화력이 약하여 살균한 배지에서 볍씨의 새싹이 돋아나오는 경우를 발견하였다. 이는 살균이 제대로 되지 않았음을 의미한다. 그래서 이동식 직화식 살균을 권하였으나 시설자재값이 감당이 안되어 엄두를 내지 못하였다. 따라서 가스버너를 도입하여 단시간에 화력을 높여 살균을 실시하므로서 세균의 증식을 막아 균사생장속도를 빠르게 하고 균사량의 축적을 높이는데 교육을 하고 컨설팅을 실시하여 개선하였다. 4. 병뚜껑과 형성틀을 대체한 링을 이용한 입봉작업시간 단축과 비용절감 버섯봉지에 배지를 담는 입봉작업을 할 때 병뚜껑과 그의 형성틀을 끼우고 솜을 조금 뜯어 톱밥배지 위에 놓는 작업을 한다. 이는 아주 잘못된 방법이다. 왜 그렇게 하는가하는 것은 이해가 간다. 그렇게 하는 이유는 접종할 때 실내에서 그냥 접종하므로 뚜껑을 열때 보호막 역할을 할 것으로 생각하고 그렇게 하는데 천만의 말이다. 어떻든 뚜껑을 열면 잡균이 들어가는 것은 마찬가지이다. 그래서 이 솜을 배지표면에 놓으면 마른 솜이 그렇지 않아도 수분이 적은데 이 솜이 수분을 또 빼앗아 가버린다. 그래서 균사생장이 늘려 15일이면 다 자라야할 균사배양기간이 한달씩 걸려도 표면만 살짝 잘린 결과가 빗어진다. 이렇게 표면만 균사가 사탕 발림식으로 자라면 품질이 저하되고 수량이 적고 병해충에 저항력이 약해지게 된다. 따라서 뚜껑과 형성틀, 솜을 모두 없애고 봉지 상단부위를 U자형으로 꺽어서 링을 끼우는 방법을 실제로 실험으로 보여준 결과 작업능률이 5배로 빠르고 작업공정이 빨라짐으로서 세균번식밀도가 적어 균사생장 속도가 2배로 빨라졌고 수량이 배가됨을 증명하고 보급하여 많은 호평을 받았다.

The study consisted of a survey of the residential satisfaction level of the 3rd grade students and a survey of accessibility from farms for practical field training to public facilities. According to the geographical location of the farms on the map, the average distance to facilities related to convenience or safety and health that students complained was about 12km. And that to social and public facilities was about 4.4km. Students pointed out the convenience of using transportation, commercial and convenient facilities, and the safety of anti-crime security facilities as complaints during the practice session. Residential satisfaction levels in five realms, such as facility and structure, convenience, safety, comfort and sociality, were not all reached at the satisfaction level. In particular, the satisfaction level of female students was sub-normal in the safety and convenience realms. The average satisfaction levels reviewed by department were sub-normal for horse industry and floriculture departments. By residential patterns, satisfaction with sharing with the farmers was higher than with other patterns. And satisfaction level by housing structure was much lower in the assembly and container structures Since residential satisfaction level is determined by the inside and outside environment of the dwelling, college should provide students with accurate and vivid data using information communication technologies.

This study was carried out to investigate on several factors, which contaminative the water quality through the water pipe during feeding water, in 42 largescaled apart-ments(total 84 cases) and assayed the Volatile Organic Compounds(VOCs) and concen-tration of heavy metals that inflow and outflow in reservior water in Jeonnam area(Mokpo, Suncheon, Yeosu) from January 1999 to December 1999. The results obtained were summarized as follows ; 1. The quality of the water pipe composition in the order of frequency in the quality of water pipes were Copper(45.2%)> Zinc(38.9%)> Stainless steel(9.5%)> PVC(4.8%)> PM(2.4%) in observing 42 sites. All of the drain pipes were used the cast iron quality. 2. The result of certification curve from 12 items(17kind) of VOCs was $1.0-4.0{\mu{g}}/{\ell}$ range, a coefficient of correlation was shown 0.99 over. A MDL of each substance range was within $0.1-1.0{\mu{g}}/{\ell}$. 3. The result of the assay, 5 kinds(Viny chloride, Dichloromethane, Ethylbenzene, M,P-xylene, Styrene) of the VOCs of 14 kinds was not detected and the other items were detected slightly. The detection rate of one item and over in total VOCs samples, were 25.9% in inflow and 27.9% in outflow. And frequency of detect in inflow/outflow of THM(Chloroform, Bromodichloro-methane, Dibromochloromethane, Bromoform) were shown higher than 94.1%, 97.0% each stages. It comes to the conclusion that all of the samples were reason able for drinking water standards. 4. The coefficient of correlation were reasonable, it shown 0.999 over in $0.1-1.0{\mu{g}}/{\ell}$ of a measuring range conditions of 4kinds in organic substance(Zn, Cu, Fe, Mn). 5. The results were showed suitability in 78 cases(92.9%) and unsuitability in 6 cases (7.1%), in 84 cases of in organic substances. Compare to inflow stage, mean concentrations of heavy metal, were increased slightly in Zn, Cu, Fe except Mn than outflow stage. The result of the mean concentration in organic substance inflow and outflow in the apartment water tank using Pair-compared T-test, in 95% reliance index, were $0.179mg/{\ell}(0.151-0.307mg/{\ell})$ in Zinc, $0.136mg/{\ell}(0.113-0.230mg/{\ell})$ in Copper, $0.052mg/{\ell}(0.048-0.098mg/{\ell})$ in Fe, and there was a bit growing tendency but there was no differece in Mn. 6. The mean concentration of Copper which used Cu pipe as a water supply pipe in apartment were $0.216mg/{\ell}(0.161-0.338mg/{\ell})$ in case of the Zine pipe were $0.286mg/{\ell}(0.204-0.435mg/{\ell})$. It shows that the detection rate was more higher than the other material used in Cu or Zn as the water supply pipe. We supposed to Cu and Zn substance were gushing out water supply pipe.

This study was conducted to determine physiological responses rice cultivars to glufosinate-ammonium. Changes of total protein content, protein population, glutamine synthetase activity, accumulated ammonia content and free amino acid composition were examined in both tolerant and susceptible rice cultivars. Tamjinbyeo and Fukei 126 showed relatively tolerant response to glufosinate-ammonium while Namyeongbyeo, Palgongbyeo and Youngdugbyeo were susceptible to it. Total protein content of two tolerant cultivars was 93.2 of the untreated control in average but three susceptible cultivars showed 76.5 of the untreated control in average, showing 16.7 difference. Protein profiles of the tolerant cultivars seemed to be not affected by glufosinate-ammonium treatment. However, in susceptible cultivar like Namyeongbyeo, 10ppm of glufosinate-ammonium application resulted in decrease of band density or disapperance of spot density in near 20kD and in between 45kD and 66kD on 2D-PAGE. Glutamine synthetase activity in susceptible cultivars was markedly inhibited by glufosinate-ammonium treatment, accompanying remarkable increase of ammonia content by three times greater than tolerant cultivars, and markedly increase of glutamic acid, showing 430% of the untreated control.
