Since diplomatic relations with China in 1992, many Korean companies have entered into China and that expansion is currently continuing. But now, many of Korean enterprises tend to withdraw and return to the domestic, this is because that major factors are too much fast increasing in labor costs and the difficulty of local workforce management. In this study, it is researched that the type of human resource management of Korean firms entering into Heilongjiang Province, Harbin and the similarities and differences were investigated by comparing the form of personnel management of existing areas and Harbin area, and then this study was conducted the survey and interview of domestic companies operating in Harbin, to pursuit the efficient way to manage the workforce development and management strategies. The result of researches and workforce development strategies of entering firms are as follows; First, it is required to establish a human resource discovery system for entering companies in focusing on managerial work ability and on blue-collar which is separated by professional and technical experts and a simple blue-collar people. Second, it is required to entering companies that they have to grow up the promotion and exchange of the Department of Korean Studies in Harbin and have to build the industry and universities training programs to promote needed experts, and have to establish the expert pool systems to support the flexible labor supply.

The regeneration of lost periodontal tissue is a major goal of therapy. Periodontal ligament cell(PDL) is a specialized connective tissue that connects cementum and alveolar bone to maintain and support teeth in situ and preserve tissue homoeostasis. Bone morphogenetic proteins(BMPs) have shown much potential in the reconstruction of the periodontum by stimulate new bone and new cementum formation. Limitiations of BMP administration to periodontal lesions is high dose delivery, BMP transient biological activity, and low bioavailability of factors at the wound site. Gene delivery method can be alternative treatment strategy to deliver BMPs to periodontal tissue. The purpose of this study is to investigate efficiency of BMP-2 gene delivery with cell-based therapy using PDL cells. PDL cell were transduced with adenoviruses encoding either BMP-2 or Lac-Z gene. To evaluate osteogenic activity of expressed BMP-2 on PDL cells, we investigated secreted BMP-2, cellular activity, ALPase, produced mineralized nodules. To evaluate collagen scaffold as carrier for transduced cell delivery, we examined morphology and secreted BMP-2 of transducd PDL cells on it. BMP-2 transducd PDL cells produced higher levels of BMP-2, ALPase, mineralized nodules than non transduced cells. Cellular activity of transduced cells was showed similar activity to non transduced cells. Transduce cells attached on collagen scaffold secreted BMP-2 at 7day and was showed similar morphology to non transduced cells. These results demonstrated that transduced PDL cells produced biologically active BMP-2 and collagen scaffold could be carrier of transducd cells.

Essential hypertension, one of the leading primary cause of death in Korea, is a typical chronic disease requiring adequate and continuous management. Though these hypertensives need to maintain desirable health practice by themselves for their life time, many previous studies indicated that most of the essential hypertensives have no specific symptoms and thus, reluctant to follow appropriate medical regimens causing the condition further aggravated and complicated. Thus the comprehensive self-regulation program was conducted as a nursing intervention on the promotion self-care 'performance and improvement in physical parameters of hypertensives. For this purpose, a one group quasi -experimental research with pre and post test design was used. And the whole program was carried out from October, 1993 to February, 1994. Self-regulation program was consisted with group education on hypertension and self-care, self-regulation including the blood pressure self-monitoring and recording, recording of daily self-care activities, and encouraging and reinforcing self-efficacy through verbal persuation and enactive attainment. The subjects were asked to measure their own blood pressure by themselves twice per day and to record blood pressure and the daily self-care performance according to the instructions provided during the whole period of 9 weeks. The data was analyzed by experimental stages: the first week, the fifth week, and the ninth week since the experimental imput began. Data were analyzed by the SPSS PC+ program with paired t -test and F-test, and multiple correlation to determine the variables affecting the effect of program. The results were as follows : 1) Subjects in J company were significantly lower diastolic blood pressure than K company after the program (t=2.39, p=.024). Level of cholesterol was significant difference according to position(t=2.23, p=.034), family history (t=-2.66, p=.013), diagnosis duration, and career(t=2.88, p=.055). Perceived self-efficacy was more significantly increased among the group with family history(t=-3.00, p=.013). 2) Before the program, there were significant positive correlation among the variables: internal-LOC and self-efficacy(r=.3952, p=.015), external-LOC and barriers (r=.6515, p=.000), chance-LOC and Barriers(r=.4133, p=.012). However there were significant negative correlation between internal-LOC and barriers (r=-.3236, p=.041, external-LOC and self -efficacy(r=-.3517, p=.028), self-efficacy and barriers(r=-.6654, p=.000). 3) There were significant relationships between changes in self - care performance and self-efficacy at 5th week (r=.5313, p=.001) and changes in self-efficacy at 9th week(r=.4586, p=.005). 4) After the program, internal health locus of control and perceived benefits showed significant correlation(r=.5673, p=.001, but perceived barriers was negative correlation with perceived self-efficacy (t=-4242, p=.01). From the above results, it can be concluded that the self-regulation program is an effective nursing strategy through the change of variables to promote self-care performance of hypertensives and to increase the self-efficacy. Thus this program can be recommended in the management of the hypertensives in workplaces and community settings.

The raise of the acceleration can be one of possible methods to increase the scheduled speed of the metropolitan railway system. It is possible to raise the acceleration to the some point by increasing the traction power of the motor. However, there is a limit of the acceleration because the traction power over some level related to the adhesion causes a slip, which prevents from accomplishing the target acceleration. The running resistance is also an important factor to consider. Both the adhesion and the running resistance as well as the traction power vary according to the velocity. Therefore, the standardization of the acceleration needs the analysis of these factors as a function of velocity. In this study, we focus on the advanced urban transit unit(AUTS) for the standardization. We derive a novel equation of the adhesion suitable for the AUTS by investigation of the traction and adhesion equation as well as the experiment data. And finally we propose the standard of the acceleration based on this analysis.

This study reviewed the examples on analyses of the potential impacts to waste management, due to the recent trends of waste trade regulation, and summarized an analysis strategy of the impacts. As a result, a desirable analysis may begin with reasonable estimation of recent waste amounts and flows, and reasonable prediction of the future trends of waste amounts. Then, it is effective to list various key factors and derive future scenarios of the impacts, as well as employ the traditional viewpoints focusing on waste material flow or environmental regulations. The applicable analyses for each scenario can be largely divided into qualitative and quantitative methods. Due to a high uncertainty in the recent international situations with entailing possible innovative economic changes, qualitative methods may be considered in advance, and then quantitative techniques may be utilized to predict gradual changes at relieved uncertainty of the situations. Based on this review so far, proper methodology and procedures for the impact analysis were suggested on recent waste trade conditions in Korea. Given existence of the recent uncertainties such as the health and economic crises, the analysis preferably focused on deriving strategic scenarios with respect to various aspects, and suggested analysis methods applicable to each scenario.

This study explores an initial framework for online product categorization by examining the relationships among Internet motivations, buying tendencies, and online purchase intentions for product categories. A total of 217 usable questionnaires were obtained from respondents in a southwestern state in the United States. A path model using a correlation matrix with maximum likelihood was estimated using LISREL 8.53. Findings indicated that Internet motivations consisted of four factors: Diversion, Economic, Information, and Social motivations. In addition, online products were classified into three categories based on purchase intentions: Sensory, Cognitive, and Search products. Estimated path model showed that diversion and economic motivations affected impulse buying tendency, whereas economic, information and social motivations influenced planned buying tendency in the online context. Also, the buying tendencies were significantly related to online purchase intentions for the product categories. Purchase intentions for sensory products were more strongly affected by impulse buying tendency, whereas purchase intentions for cognitive and search products were more strongly affected by planned buying tendency. Theoretical and managerial implications were discussed for devising an appropriate e-market strategy for specific product categories.

This study is a literature analytical process for studying the drawing teaching methods considering the professional characteristics of animation and a principle analytical process for studying the perspective that when teaching methods that consider the function, learning and creative mechanisms of the brain are applied, the animation drawing ability will be effectively increased. In recent years, as an alternative discussion on the educational method of each field, study results applied with brain-based learning principles are being presented. This is not only being applied and implemented for art and drawing education but as overall educational alternatives. On the other hand, animation drawing requires artistic literacy and at the same time requires comprehensive teaching methods that can train the structural knowledge, cognitive sensation and communication method but such professional teaching methods are insufficient. Therefore, the principle of effective education is seen through the brain mechanism and the principle of demonstrating the creativity and learning by the brain is analyzed. In addition, through the fundamental relationship on the picture drawing and the function of the brain, the relationship of the drawing and the brain is identified. As a result, not only for the left brain that observes the cognitive information which can draw the structure and shapes but the right brain which is directly related to the drawing should be developed, but in order to express the creativity, teaching methods that can understand the mechanism of comprehensive brain where physical and psychological factors are expressed should be also developed. It is because the animation drawing education is teaching the methods for demonstrating the characteristics of artistic creativity required for the drawing ability. This process will not only be a foundation for identifying the difference against the previous animation drawing teaching methods, and the brain-based principles will be selected as the core strategic definition for designing the strategy and methodological model of future education.

Survey on plant diseases occurring on cucumber cultivated in plastic film house of experimental farm in Suwon was conducted. Through the survey, occurrence of damping-off, downey mildew, powdery mildew and Fusarium wilt was observed. Especially downey mildew caused by Pseudoperonospora cubensis was the most severe foliar disease of cucumber. To control the disease effectively, effects of installation of ventilation fan and optimal spray timing of a chemical, dimethomorph+copper oxychloride WP, were investigated. Two ventilation fans installed at the front and at the back of plastic film house reduced air relative humidity by about 6.4% and downey mildew incidence by 55.7%. Downey mildew incidence on cucumber from untreated chemicals plot in plastic film house installed with ventilation fan was on a equal level with that from treated chemicals plot with three times application of dimethomorph+copper oxychloride WP in plastic film house without ventilation fan. Meanwhile in order to select optimal chemical application time, dimethomorth+copper oxychloride WP was treated three times at 7 days-interval from three days before the disease occurred, right after the disease occurred, and two days after the disease occurred, respectively. The result showed that dimethomorth+copper oxychloride WP applied to cucumber leaves and stems from three days prior to, right after, two days after occurrence of downey mildew reduced downey mildew incidence by 72.9, 61.8, and 23.7%, respectively. The above results showed that regulation of environmental factors like air relative humidity and preventive application of chemicals should be considered to establish control strategy to downey mildew.

This study analyzed the current situation of medium and small-sized hospital nursing staff and related policies, and identified the factors that affect staffing level to provide evidence for planning and adopting policy. By analyzing the statistical data published by public institutions such as the Ministry of Health and Welfare and Health Insurance Review and Assessment Service, the result was viewed based on the understanding of various internal and external health care environments. The number of active nurses was less than 50% of the number of licensed nurses and has decreased every year. This means that the cost-effectiveness of increases in nursing college enrollment should be reconsidered. Inpatient nursing fees by staffing grades has caused nurses to move from medium and small-sized hospitals, where there is a severe lack of staff, to more advanced general hospitals. As a result, the lack of nursing staff in medium and small-sized hospitals has worsened. In conclusion, reexamination is needed to improve effectiveness of inpatient nursing fees by staffing grades as a policy to secure the workforce of medium and small-sized hospitals. Furthermore, the tracking management system of licensed nurses must be able to solve the imbalance between demand and supply of nursing staff.
