Clouds are an important factor in aircraft flight. In particular, a significant impact on small aircraft flying at low altitude. Therefore, we have verified and characterized the low level cloud prediction data of the Unified Model(UM) - based Local Data Assimilation and Prediction System(LDAPS) operated by KMA in order to develop cloud forecasting service and contents important for safety of low-altitude aircraft flight. As a result of the low level cloud test for seven airports in Korea, a high correlation coefficient of 0.4 ~ 0.7 was obtained for 0-36 leading time. Also, we found that the prediction performance does not decrease as the lead time increases. Based on the results of this study, it is expected that model-based forecasting data for low-altitude aviation meteorology services can be produced.

Enzymes involved in catecholamine synthesis are present in the highest concentration in the adrenal medulla, however they were found also in other, mainly nervous tissues. Increased transcription of genes for catecholamine biosynthetic enzymes is an important mechanism to increase the capacity for epineprine/norepinephrine biosynthesis with stress. Gastrodia elata(Chinese name: Tienma), are very important Chinese herbal medicines used for the medical treatment of headaches, migraine, dizziness, epilepsy, rheumatism, neuralgia, paralysis and other neuralgic and nervous disorders. Immobilize stressed rat markedly increased tyrosine hydroxylase (TH) mRNA and dopamine-${\beta}$-hydroxylase (DBH) mRNA transcriptior level more than control group. But treated Gastrodia elata extracts in immobilized stressed rat slightly increased TH mRNA and DBH mRNA transcription level more than normal group. In addition, we are obtained identical results in PC12 cell line. Decrease of transcription level of TH mRNA and DBH mRNA is indicating that Gastrodia elata have a anti-stress effects which decrease the transcription level of TH and DBH mRNA on catecholamine biosynthesis pathway.

Recently the recongnition of Logistics becomes important to enterpries as a means for improving their competition, but the Korea enterpries falls for far behind in management techniques for analyzing realities and problems in the Logistics compare to the advanced countries. Especially the function of inventory control which is most undeveloped in them should be improved in Korea. Inventory is very important in Logistics, but there exists trade-off between inventory level and customer in the service level. It is difficult to coordinate both the reduction in the inventory level and the enhancement in the service level. Its effective technique is a DRP system. In general, it deals with arborescent distribution network in which a given channel member has a single source of supply. This article aims to present a DRP system, and more a DRP system which is flexible and responsive in the multisourcing, multi-echelon distribution network. Related research issues are discussed. Finally, using a DRP system on logistics and the management performance. So we can help the physical distribution improvement of the Korean enterprises.

Evaluation indices for products or services are important to improve the internal process of the company and to compare those with competitive ones. The sigma level in Six Sigma management does important role to evaluate the core characteristic, CTQ(Critical To Quality), derived in the considered product/service or process. In this research, we propose an overall evaluation index for the product/service or process with multiple characteristics, in other words, multiple CTQs. The proposed overall evaluation index is useful for the cases that the single CTQ is not enough to evaluate the practical interests, for example, the final products and services with complex procedures and relatively large scaled processes. This approach is discussed with sigma level for applying Six Sigma Projects, however, it is applicable to indices based on proportion or percentage as well. The practical examples with a manufacturing process and a customer survey based on focus group interview are given for illustrations.

This study examined the impact of attachment styles on the size and the level of functions of social networks. 270 mothers of school children responded to the questionnaire and were classified into secure avoidant and anxious attachment groups. Findings indicated that three continuous attachment indexes security avoidance anxiousness and the size and the level of functions of social networks were not affected by mother's age educational level and employment status. However singnificant attachment style effects were obtained for the size and the level of functions of social networks. Secure subjects perceived their husbands closer and more important and listed more nonkin members in their netoworks than anxious subjects. important and listed more nonkin members in their networks than anxious subjects Also secure people perceived receiving more assistance from network members including household tasks money information and advice Secure and anxious subjects reported more emotio al support from networks than avoidant people.

Not much attention has been paid to the characteristics of successful MIS in small business in Korea. This study compares the characteristics of successful MIS with those of less successful MIS of manufacturing industry in Korea in terms of micro level, macro level, and personal level. The micro level consists of those variables relating to the system development and maintenance while the macro level consists of the environmental variables relating to the information systems. The personal level measures a personal EDP experience. A mail survey was sent to small manufacturing companies to collect the data for the hypothesis tests. And 81 usable questionnaires were returned for data analysis. This study performs the validity of the categorization of variables in terms of three levels. The results shows that this categorization is appropriate but the personal level. As the personal experiences of EDP in Korea used to come up with those of the organization, the variables in the personal level have high correlations with those in the macro level in empirical testing. As the personal level, however, is different dimension from the macro level in theoretical aspect, the level is maintained separately throughout the study. The data were analyzed with MANOVA and two group discriminant analysis. The analyses reveal that the characteristics of successful MIS are different from those of less successful MIS in terms of three levels. And the micro level is more important than the macro level to develop successful MIS. That is because the organizations have relatively few experience in dealing with information systems, they have not developed unique information systems which are adjusted to their organizational characteristics. Those findings seems to be important determinants of success for the MIS in a firm.

This study analyzed the level of digital informatization and the level of human relationship satisfaction in the disabled group. The digital informatization level of the disabled refers to the level of smart access, smart capability, and smart utilization. For the sampling of persons with disabilities, the survey was conducted for persons aged 7 to 69 who were registered under the Welfare for Persons with Disabilities Act. Regression analysis utilized SAS 9.3.s through vitalization of local communities, and information education for the disabled is also important. The analysis results are as follows. First, the higher the digital access level of the disabled, the higher the level of interpersonal satisfaction. Second, the higher the digital information capability level of the disabled, the higher the level of interpersonal satisfaction. Third, the higher the level of digital information utilization of the disabled, the higher the level of interpersonal satisfaction. As a result, the higher the digital information level of the disabled, the higher the satisfaction level in the interpersonal relationship of the disabled. In addition, it was found that careful attention and policy review are needed to resolve the digital information gap of the government for the disabled who are marginalized groups. Therefore, it is necessary to provide the expansion of universal services of the marginalized groups including the disabled. In addition, it is important to form a culture in which the community embraces the marginalized class through vitalization of local communities, and information education for the disabled is also important.

Purpose: Asthma is the most common chronic disease of childhood. It's important mother's caring for management of children with asthma. This study was to provide the evidenced data for preparing an educational program by identifying the knowledge level and educational demand about pediatric asthma of mothers of children with asthma. Method: The subjects were 91 mothers of children with asthma who admitted at 3 hospital in Busan. The data were collected through a self-reporting questionnaire from Feburary to May, 2005. The data was analyzed by SPSS 10.0 program. Results: The total mean percentage of correct answer of knowledge about pediatric asthma was 55.6% and the total mean $score{\pm}SD$ of educational demand about pediatric asthma was $4.40{\pm}0.50$. The knowledge level was statistically different by recurrence number(F=3.08, p=.049). There was not correlation between knowledge level and eucational demand. Conclusions: The mothers of children with asthma had a medium knowledge level and a high educational demand. Based on the results, mothers' knowledge is an important part of children with asthma management. Therefore nursing intervention program for mothers of children with asthma should be developed and the mothers should cope with asthma effectively.

PISA 2012 showed that while Korean students achieved high-level math achievement in mathematics their levels are relatively lower in math self-efficacy. Students from Singapore, on the other hand, achieved high scores both in math achievement and in math self-efficacy. The results of the two countries differed although both countries has been sharing the same East Asian cultural sphere. This study analyzed the input and the process variables on the student- and school-level concerning math self-efficacy. The results were as follows. In Korea, math interest, instrumental motivation, elaboration strategies, applied and pure math tasks were the student-level variables that affected math self-efficacy. In Singapore, math interest, control strategies, elaboration strategies, applied and pure math tasks were the student-level variables that affected mathematics self-efficacy. Math club, teachers' low expectations were the school-level variables that affected math self-efficacy. For a higher-level of math self-efficacy in Korea, it is important to encourage students not only to use control strategies, but to participate in math clubs. It is equally important for teachers to have higher expectations towards students.
