  • Purpose: This study aims to obtain basic data for conceptual establishment of sports participation and perceived benefits by considering prior research on the effects of sports participation to derive variables for perceived benefits of sports participants. Research design, data, and methodology: This study used an integrated literature review. A conceptual model is designed with reference to a prior study by adopting a guiding theory. Based on the key words. The literature collection was conducted online, and the reference period for the literature collection was for studies published between 2015 and 2020. Results: First, a total of seven related variables were derived from the literature analysis related to sports participation and physical benefits. Second, a total of six variables were derived from the literature analysis related to sports participation and mental benefits. Third, a total of four related variables were derived through a literature analysis related to sports participation and social benefits. Conclusions: Health fitness, objectified body consciousness, and social body shape anxiety, including body composition, approach physical benefits among perceived benefits through sports participation, and physical self-efficacy and physical self-concepts are related to physical benefits but are also shown to be related to mental benefits. And successful aging is seen to be close to social benefits and related to some mental benefits. Mental and social benefits can be seen as the variables derived from the results being related to the benefits, and more in-depth exploration of perceived benefits is needed.

  • With the rapid development of computer technology and communication networks in modern society, human economic activities in the almost every field of our society depend on various electronic devices. The huge amount of digital data generated in these circumstances is refined by technologies such as artificial intelligence and big data, and its value has become larger and larger. However, until now, it is the reality that the digital data has not been clearly defined as an economic asset, and the institutional criteria for expressing its value are unclear. Therefore, this study organizes the definition and characteristics of digital data, and examines the matters to be considered when considering digital data in terms of accounting assets. In addition, a method that can objectively measure the value of digital data was presented as a quantitative calculation model considering the time value of profits and costs.

  • Objectives: This study investigated how income, duration of illness, social stigma, quality of sleeping, ADL and social participation related to Parkinson's disease(PD) predict depression in a conceptual model based on the International Classification of Functioning(ICF) model. Methods: The sample included 206 adults with idiopathic Parkinson's disease(IPD) attending D university hospital in B Metro-politan City. A structured questionnaire was used and conducted face-to-face interviews. The collected data were analyzed for fitness, using the AMOS 18.0 program. Results: A path analysis showed that the overall model provided empirical evidence for linkages in the ICF model. Depression was manifested by significant direct effects of social stigma(${\beta}=.20$, p<.001), quality of sleeping(${\beta}=-.40$, p<.001), ADL(${\beta}=-.20$, p<.01), and social participation(${\beta}=-.12$, p<.05), indirect effects including income(p<.05), duration of illness(p<.05). These variables explained 45.9% of variance in the prediction model. Conclusions: This model may help nurses to collect and assess information to develop intervention program for depression.

  • We, clinical nurse specialists practising and guiding student practice in a Community health nursing clinic, wanted to develop a family pattern appraisal consistent with Rogers' conceptual system, the nursing model guiding our practice. We use Rogers' model because it is harmonious with the traditional Korean view of the one human, natural and cosmic world. The purpose of our research was to contribute to science - based nursing practice, not only, one helpful model, but also a model of how to use, in guiding practice, a conceptual system which reflects nurse practitioners' philosophy of nursing, is intellectually satisfying, and enriches meaning in daily nursing life. The research objectives were to review the literature on Rogers' model and analyse it according to Kim's five - level analytical framework, to explore Rogers' definition of family, to review appraisals based on Rogers' model, and to develop a family appraisal which is culturally appropriate for use in our community. This work including the use of the appraisal and its refinement with families in our practice which was done during 1994 and 1995, in Seoul, in the Capital of the Republic of Korea. At the highest level of analysis, Rogers conceptual system emphasizes acausality and multidimentional meaning ; the world view is characterized by process, movement and wholeness. The epistemology Is one of holism and the knowledge base includes all forms of experience, from sensory to mystical, objective, and subjective. At the metaparadigm level, nursing focuses on the unitary human being and the environment. At the level of nursing philosophy, the model identifies human being, nursing, nurse, and illness and health. At the paradigm level the model assumes the irriducibility of the human to parts, noncausality and continual change. Rogers' practice methodology consists of pattern manifestation appraisal and deliberative mutual patterning. Under-standing patterns and patterning of people is the key to helping them achieve their potential. At the theory level, the basic assumptions, key concepts, and homeodynamic principles were identified. Rogers states the family energy field is an undividable, four-dimensional negentropic energy field which is in a larger envircinmental field show-ing such characteristics as cannot be predicted by knowledge of individual family members. Based on the word of Rogers scholars, we chose Rogers' correlates of patterning to understand the family unit as a whole-frequency, rhythms, motion, time perception, sleeping-waking beyond waking, pragmatic -imaginative-visionary to develop the appraisal. We, also used some of Barrel's (1988) criteria including interpersonal network and professional health care access and use, and Cordon's (1982) criteria including self perception - self concept modified to fit the family. Our family Pattern appraisal included 1. Influencirg data, 2. Professional health care access and use, 3. Family self perception-self concept, 4. Family interpersonal network, 5. Sleep-wake-be-yond waking, 6. Pragmatic-imaginary-visionary, 7. Family frequency and rhythm, 8. Family motion, 9. Family time perception. The appraisal was used with four families and modified to eliminate overlap and to make it possible for the family member to express themselves more easily. We plan to gain more experience with the appraisal toward further development of the tool.

  • The demand for personalized products and service of apparel product has increased dramatically. In order to acquire a personalized apparel product, consumers may have to sacrifice more expense or time. The purpose of this study was to investigate various personalization strategies in apparel business and to identify antecedents that influence the process. Clothing involvement and two price related variables (clothing expense and willingness to pay more) were included in the study as antecedents. Four personalization strategies were included in the study: design selection, size customization, in-store service and promotion personalization. For an empirical study, a conceptual model was designed and research questionnaire was developed. A measure of personalization of apparel shopping was developed based on existing scale items of prior research and a pilot study. Data from 766 men and women in their twenties to forties were used for statistical analysis. Structural Equation Modeling was used for the data analysis. Results indicated that the conceptual model was a good fit to data. Structural paths indicated that there was significant influence of clothing involvement on design selection and sales promotion personalization strategies. Involved consumers spent more on chothing products and were likely to pay more on personalized products and services. Monthly clothing expense influenced size customization significantly. It also had negative influence on service related personalization strategies. Consumers were willing to pay more when it comes to product related personalization strategies such as design and size but not necessarily to service related strategies. This study was an attempt to provide an in-depth and synthesized approach on consumer attitudes toward personalization of apparel products.

  • 항행중인 선박은 GPS, AIS, ECDIS, ARPA Radar 등 다양한 해양 장비를 통해 선내 외 상황에 대한 여러 정보들을 전달받고, 항해사는 이러한 다양한 정보를 이용하여 자선박의 항행 안전 상황을 인식 및 예측한다. 하지만 그로 인해 항해사의 장비 주시에 대한 업무 부담이 이전보다 증가하였으며, 때로는 장비 간 정보의 불일치가 발생하여 항해사를 혼란시키기도 한다. 이전 연구에서 이러한 문제를 해결하기 위해 항해사를 보조할수 있는 지능형 항행안전 정보 시스템의 개념모델과 CF(Certainty Factor)전문가 시스템을 이용한 그 개념모델의 예를 보인 바 있다. 정보 융합 기술에는 다양한 추론 기술들이 요구되는데 CF전문가 시스템만으로는 항해사의 의사결정과 같이 애매하고 불명확한 요소를 반영할 수 없다. 이 연구에서는 불명확한 요소를 반영할 수 있는 퍼지 전문가 시스템을 이용한 항행 정보 융합 방법을 제안하고, 제안된 방법을 설계 및 구현한 후 특정 시나리오에 대한 실행 예를 보임으로써 항행 정보 융합 시스템에 퍼지 전문가 시스템을 활용하는 것의 타당성을 보인다.

  • 이 연구는 디지털 환경에서 데이터가 중심이 되는 전자기록의 출처에 새롭게 접근하기 위해, 데이터 출처 개념과 출처 모델을 검토하고 수용하여, 어떻게 전자기록을 대상으로 새롭게 출처 개념을 적용할 수 있을지의 가능성을 살펴보았다. 이어서 데이터 중심의 전자기록을 대상으로 한 출처 표현 모델을 개발하기 위해 기초 연구를 진행하였다. 특히 소급형 출처와 전망형 출처 개념으로 전환할 것과, 기록관리 메타데이터와는 별개의 모델을 통해 출처를 표현하고 기록과 연결할 수 있는 모델을 개발할 것을 제안하였다. 기록과 동적 관계를 맺으면서도 독립적으로 출처를 표현할 수 있는 모델을 개발할 수 있다면, 오히려 기록의 유동성을 보장할 수 있으면서도, 기록의 속성과 이를 지원할 출처의 역할을 더 충실히 수행할 수 있을 것이다. 결국, 이 연구가 제안한 기본적인 모델 개발 방향을 수용하는 출처 모델은 기록의 고정성과 활동의 재현성, 재현의 신빙성을 뒷받침할 수 있을 것이며, 디지털환경에서 적합한 출처 모델로서 역할을 할 수 있을 것이다.

  • Nitrogen pollution in urban and rural groundwater is a common problem and poses a major threat to drinking water supplies based on groundwater. In this work, the kinetics of nitrification-denitrification coupled reactions are modeled and new reaction modules for the RT3D code (Clement, 1997) describing the fate and transport nitrogen species, dissolved oxygen, dissolved organic carbon, and biomass are developed. The proposed nitrogen transformations and transport model showed very good match with results of a conceptual model. However, the model simulation results for the major reactive species should be tested for validation using experimental and field data.
