  • Purpose: The purpose of this study was to explore the health-illness transition of patients with Young-Onset Parkinson's Disease (YOPD). Methods: From June to November 2011, 17 patients with YOPD who visited a neurologic clinic in a tertiary hospital participated in the study. Data were collected through in-depth interviews and analyzed using the grounded theory of Strauss and Corbin. Results: The core category of the participants' health-illness transition emerged as 'reshaping identity following uncontrollable changes'. The participants' health-illness transition process consisted of six phases in sequence: ego withdrawal, loss of role, frustration, change of thought, modification of life tract, and second life. Although most participants proceeded through the six phases chronologically, some returned to the frustration phase and then took up the remaining phases. Conclusion: The study results provide an in-depth understanding of health-illness transition experiences in the participants. These findings suggest a need to develop appropriate nursing intervention strategies according to the different phases in the health-illness transition of patients with YOPD.

  • This article attempts to examine the well-known law that the increasing returns to scale(IRS) is effective in the Internet business. The effect of IRS is one of the hottest issues in the Internet business sector. Many cases and survey studies support the fact that the IRS phenomenon exists in the Internet business. Executives in Internet business generally give a deep trust on this theory. As the Internet business grows, however, the boundary of the business becomes widened and complicated. And each category of Internet business is characterized with a different business style and economic behavior. It may, therefore, be dangerous to accept that the phenomenon of IRS is applied to all areas of Internet business. For this reason, the research for the close look into the IRS phenomenon should provide significant implications for the managers in the Internet business industry. This article divides the internet business into four sub-areas, and analyzes the IRS phenomenon using AHP/DEA-based full ordering technique. Interpretations are given, based upon the research results, for each sub-area of Internet business, as a guideline of setting business strategies for practical managers.

  • Purpose: The Purpose of this study was to investigate how elders in rural communities maintain their sexual life. Methods: Data were collected through in-depth interviews with 20 participants who were 65 years old or older, and either were married couples or were continuing the sexual relationship though widowed. Data were analyzed based on Strauss and Corbin's (1990) Grounded Theory Methodology. Results: The core category of experiences of the elderly's sexual life was identified with 'changeable sexual life at husband's mercy'. This process could be divided into 3 stages, which were the stage of recognition of sex difference and obstacle in sexual life, the stage of observation of partner's attitude and the stage of husband's lead in sexual life. Conclusions: This study found that sexuality was an important aspect for the elderly although their sexual interests and activities declined along with aging. In addition, the husband's sexual and economic capabilities and sexual difference were very important factors in the elderly's sexual life. It is suggested to consider sexuality as a normal aspect of life for the elderly when nurses plan for their care.

  • Except the time when the relics of the museum are exhibited or loaned to the public, they are stored in a storage. Therefore, the environmental condition of a storage is a important factor. But in Korea, the appearance of the building and exhibition design are emphasized more than any other factors in planing museums, so the preservation technology has not yet reached the appropriate level and leaded to some environmental problem in the museum storage. The purpose of this study is to suggest guideline for an apt storage system by reconsidering practical notes in planning storage and give a efficient long-term plans examinable category. So this study based on the research had been stated from the recognition that the relics should be planned and placed differently in sorts, and developed this by researching the theory related to the matter throughout documents and to cope with the low efficiency in its essential role compared to the massive investment and through on-the-spot surveys emphasizing on the storage of the domestic museums in progress since 1995. Hereafter it compares the actual condition and problems of the domestic museum planning with the ones abroad, and analyzes the characteristic and difference between the two, and then establish an organized storage system.

  • Chomsky(1986b)가 제안한 장벽이론은 하위인접조건과 공범주원리를 장벽 이라는 하나의 개념으로 통합하려는 시도이다. 그럼에도 불구하고 그의 장벽 이론은 의도한 목적을 달성하지 못하고 있다. 본고는 공범주원리가 이접적으로 적용되도록 하고, 어휘지배를 핵인가조건으로 재정의하고, 선행어지배를 선행어 조건으로 대치함으로써, 후자가 하위인접조건과 선행어지배를 동시에 포괄할 수 있도록 하였다.이러한 시도는 의문사구 섭제약, 복합명사구제약, 주어조건, 부가어조건 등을 적적하게 설명해준다. 이러한 시도에 전제되는 것은 IP와 함께 VP가 의문사구이동에서 뿐만아니라 명사구이동에 있어서 예외적 범주로 취급되는 것을 막기 위해 Chomsk가 제안한 이동이론을 수정하여 통사부의 이동규칙은 부가를 허용하지 않는 것으로 보았다.

  • As the digital retail environement becomes prevalent, consumers are given greater opportunities to make purchases across physical and digital boundaries. Prior research emphasizes that the attractiveness of the digital or online channel is relatively determined by spatial specifics of physical locations. The overall market trend combined with prior research suggests that understanding spatial specifics becomes a key to managing both offline and online sales performance together. In this study, we focus on geographic variation in sales performance through offline and online channels and aim to investigate the channel-level sales difference between central and subsidiary areas. To this end, we obtain sales data of skincare and makeup products from a leading cosmetic company. Next, we examine spatial autocorrelations in data and then employ the spatial error models to study the effects of spatial specifics. The empirical findings are as follows. First, there are significant differences in category-specific and channel-level sales between central and subsidiary areas. Second, Moran's I statistics demonstrate the spatial autocorrelations of each variable. Third, spatial error models outperform simple regression models with lower AIC values. Finally, spatial specifics play a greater role in understanding online sales in subsidiary areas whereas they exert greater influence on offline sales in central areas. We believe our study advances the related theory and knowledge of multi-channel retailing and also contributes practically to location-dependent multi-channel strategies and sales data analytics.

  • The This study attempted to analyze what perception and attitude teachers have on corporal punishment. For these purpose, 458 writings about corporal punishment that 140 teachers loaded on web-site were collected and were analyzed using qualitative content analysis. : First, each writing was open-coded according to specific theme or meaning relating to corporal punishment using Nvivo program. Second, coded materials were classified as a high category when having similar theme or meaning. As a result of this process, 2 highest categories, 6 high categories and 24 subcategories were yielded. Teachers with positive view on corporal punishment tend to think that corporal punishment has some educational values or usefulness and their views were classified as very positive view, limited-permissive view, and inevitable view. They thought that corporal punishment were closely related to teachers' authority. Teachers have negative views on corporal punishment on the basis that corporal punishment causes side effects, is contrary to essentials of education, violates human rights etc. Negative views that teachers have on corporal punishment were classified as absolutely negative view and negative view focused on side effects. They thought that corporal punishment were not related to teachers' authority. Comments have been made on positive view on corporal punishment from the perspective of reflective analysis and implications of the results on theory and practice were discussed with comments on research limitations.

  • Purpose: The purpose of this study was to understand the adjustment process of middle-aged people in Korea with hemiplegia after a stroke. Method: For this study, the grounded theory method was utilized. Results: After constant comparative analysis, the core category emerged as 'rebuilding the body which was ruined'. In addition, the causal conditions were 'restriction of physical function', and 'loss of roles'. The adjustment process consisted of the 'facing reality phase', 'overcoming depression phase', 'overcoming physical limits phase' and 'reestablishing roles phase' The main strategies in the facing reality phase were 'holding on to a glimmer of hope', 'getting away from the harsh reality' and 'facing up to the reality'. The main strategies in the overcoming depression phase were 'soothing oneself', 'Self-introspection' and 'restoring self-esteem'. In addition, the main strategies in the self-initiative overcoming physical limits phase was 'discovering personal strategies and striving to recover'. The main strategies in the reestablishing roles phase were 'reestablishing a parents' role', 'reestablishing a spouse's role' and 'reestablishing social roles'. Conclusion: In conclusion, even though many middle aged stroke patients remained in the depression phase, most of them who overcame depression strived to conquer physical limits on their own initiative.

  • Purpose: This study was done to evaluate the experience of securing patient safety in hospital operating rooms. Methods: Experiential data were collected from 15 operating room nurses through in-depth interviews. The main question was "Could you describe your experience with patient safety in the operating room?". Qualitative data from the field and transcribed notes were analyzed using Strauss and Corbin's grounded theory methodology. Results: The core category of experience with patient safety in the operating room was 'trying to maintain principles of patient safety during high-risk surgical procedures'. The participants used two interactional strategies: 'attempt continuous improvement', 'immersion in operation with sharing issues of patient safety'. Conclusion: The results indicate that the important factors for ensuring the safety of patients in the operating room are manpower, education, and a system for patient safety. Successful and safe surgery requires communication, teamwork and recognition of the importance of patient safety by the surgical team.
