  • This study did quantitative comparative evaluation of changes in generation consequent on reflectivity of the protruding wall near the widow in case of application of PV window system to an apartment house. To be concrete, this study did comparative analysis of the generation of (B) through the process of composing Mock-up (A)comprising the protruding window near the window and Mock-up(B) free of nearby wall interference, and giving change to the reflectivity of the wall (Case_1~3). The analysis result showed that the difference in generation was slight in case solar radiation was less than 10,000Wh in all three conditions. On the contrary, in case solar radiation was more than 10,000 Wh, the generation as against Module(B), was analyzed to be 87~91% in Case_1(5% reflectivity), 18~60% in Case_2(85% reflectivity), and 16~71% in case_3(93% reflectivity), respectively.

  • Late talkers are young children who are delayed in their expressive language skills despite normal nonverbal cognitive ability, adequate hearing and typical personality development. The purpose of this study is to investigate the sentence interpretation strategies used by Korean-speaking late talkers and age-matched normal children. Nine late talkers and nine normal children matched by age at 30-35months were participated in this study. 27 simple noun-noun-verb(NNV) sentences were generated by factorial combination of case-marker [nominal case-marker on the first noun and accusative on the second (C1), accusative on the first noun and nominative on the second (C2), and no case markers on both nouns (C0)], and animacy of the nouns [animate-inanimate(AI), inanimate-animate(IA), animate-animate(AA)]. All the children were asked to "act out" their interpretation of the given sentence. For each type of sentences the percentage of choices of the first noun as the agent was calculated. The results of group (2) ${\times}$ animacy(3) ${\times}$ case-marker(3) mixed ANOVA showed a significant main effect for 'animacy', 'case marker' and 'group(2) ${\times}$ case-marker (3)'. The late talkers relied on semantic (animacy) cues in their interpretation of the sentences, while the normal peers utilized both animacy and grammatical morpheme (case-marker) cues. The results indicated that the late-talkers' comprehension skills were also delayed.

  • Purpose: The purpose of this study was to develop a substantive theory of case management (CM) practice by investigating the experience of nurse case managers caring for Medical Aid enrollees in Korea. Methods: A total of 12 nurses were interviewed regarding their own experience in CM practice. Data were recorded and analyzed using grounded theory. Results: Empowerment was the core category of CM for Medical Aid enrollees. The case managers engaged in five phases as follows, phase of inquiring in advance, building a relationship with the client, giving the client critical mind, facilitating positive changes in the client's use of healthcare services, and maintaining relationship bonds. These phases moved gradually and were circular if necessary. Also, they were accelerated or slowed depending on factors including clients' characteristics, case managers' competency level, families' support level, and availability of community resources. Conclusion: This study helps understand what CM practice is and how nurses are performing this innovative CM role. It is recommended that nurse leaders and policy makers integrate empowerment as a core category and the five critical CM phases into future CM programs.

  • A vehicle's differential gear is a device designed to allow the vehicle's outer wheels to turn faster than the inner wheels when turning on a curve. The differential gear case is the main component of the differential gear system, which is composed of ring gear, pinion gear and side gear, and is fastened by pinion shaft pins. The differential gear case rotates when the vehicle is running, so balancing calibration is very important. In this study, a balancing machine that can diagnose and correct the differential gear case and mass imbalance of various rotating bodies was designed. The differential gear case was rotated at high speed to accurately diagnose the location and value of the unbalanced mass, and it was designed to be balanced and corrected by removing the unbalanced mass by drilling. After calibration, it was confirmed that the unbalanced value of all the measured samples was reduced to less than 180g.mm, and the unbalance reduction ratio was improved to 60~70%.

  • Purpose: This study was conducted to identify effects of Medicaid Case Manager's communication competence and stress on their job satisfaction. Methods: The current work is descriptive research, and the participants were 154 medicaid case managers. Data were collected between May and July, 2017 through Embrain, a specialized research organization. The data were analyzed using independent t-test, ANOVA, and multiple regression. Results: The mean communication competence of the medicaid case managers was 3.61, stress 1.76, and their job satisfaction 2.74. Age and average monthly compensation brought significant differences in their job satisfaction. Their communication competence was correlated with stress (r=-.35, p<.001), but not with their job satisfaction. The stress was the most influential factor in job satisfaction (${\beta}=-.45$). Conclusion: The results of this work show that the medicaid case managers' communication competence was not an influence factor of their job satisfaction, which is different from implications from the previous studies and needs confirmation through future research. In addition the results of this study also suggest that stress management can be a useful approach to the improvement of medicaid case managers' job satisfaction.

  • This study suggested how to apply it decision-making of product development rapidly by design evaluation process to objectify and the result to quantify with viewpoint of design evaluation sets to marketability. Coverage of this method limited to the evaluation stage of design concept. The procedure of study, first of all, referred to some type of design evaluation method and their feature. And next, referred to some kinds of demand forecasting for marketing. Above an, this study focused on the method of demand forecasting by buying intentions surveys proper to the marketability evaluation of new product design. On a case study, I had investigated preference survey and buying intentions surveys about the design proposal of "language master audio". I selected the best design proposal through the conjoint analysis and also investigated demand forecasting. First, on the basis of buying intentions surveys, choose population and had produced buying demand, awareness demand, potential demand. I could estimate some profit to take out expense and cost from the buying demand. This estimated profit is marketability judgement data of product design at the design concept stage and can be utilized to measurable data for decision-making of product development. Through the case study, this method could forecast a target demand, and even if it is some difference between real sales volume, but the case study could verified that this method is effective to the evaluation of marketability in case of completely new product got on the typical category and the product category could be set up the population clearly.

  • Purpose: In the meantime, studies on the measurement methods of service quality have mainly been conducted in views of the service recipients. In this study, we introduce a co-orientation model that compares the perceptions of service provider and recipient and examine the applicability in service quality field. Methods: In this study, we conducted a case study on the specific service called 'National R&D Project Plan Evaluation Service' to examine the applicability of the co-orientation model in the service quality field. Results: We could identify the phenomenon of how service providers and recipients perceive differently about specific services introduced in the case study. This study confirms that it can be used to identify problems in mutually oriented service quality activities and to take practical measures to improve them. As we have seen in this case study, the co-orientation model is expected to be of great help in exploring opportunities for quality improvement in the area of service quality. Conclusion: The service quality co-orientation model allows the service provider to distinguish between what they think of differently with the service recipient and what they have in common, so the service provider will be able to find the agenda of service quality improvement.

  • This study aims to investigate the possibility of Investor-State Dispute under Korea US FTA in relation to Korean environmental impact assessment scheme. The study analyzes the Investor-State Dispute case between Bilcon of Delaware and the government of Canada. The case study shows that Bilcon challenged Canada with violations of NAFTA 1102, 1103 and 1105, arguing that Canada treated Bilcon in an arbitrary and discriminatory manner. The study analyzes two different scenarios that Korea could face with arbitration for alleged breach of its obligations under the Korea US FTA in relation to EIA scheme. From analyzing the case study in relation to two different scenarios, the study finds that problems previously identified and associated with EIA scheme in Korea could directly or indirectly cause Investor-State Dispute Settlement process between Korea and American investors. The study concludes that the risk of violating Korea US FTA related with Korean EIA could be reduced by creating Korean EIA scheme in a transparent and unarbitrary manner which guarantees fair public participation and elaborating the concrete meaning of sustainable development in EIA law.
