The Purpose of this study is to Identify and analyze the factors that determine the survival or success of internet-based companies in the start-up phase. The reason why we focus on companies which are in the early stage of development is because internet business is still at its early stage, and statistics indicate that many internet businesses have failed during the start-up phase. Using the model of new product outcomes proposed by Cooper(1979), we have formulated a conceptual model for more successful internet business ventures. On the basis of this model, the relationship between the financial and non-financial performance and various variables in the model is analyzed. For collecting empirical data, a web-based survey questionnaire was designed. A total of 97 usable questionnaires were gathered from internet companies nationwide. The results showed that controllable variables such as the commercial entity and information acquired during the new business process are related to the non-financial performance, while environment variables such as the compatibility of the resource base of the firm with the business, including a few controllable variables, are related to the financial performance. Future research needs to explore more precisely how the success factors are different according to the types of internet businesses and/or the stages of growth of the business.

The study focuses on the relationship between SB, corporate social responsibility (CSR), and the emerging economy. Thereafter it highlights the types, principles, and funding cycle of SB with the evidence from Grameen Bank, which is a globally well-recognized microfinance venture in Bangladesh established by the Nobel Laureate Dr. Muhammad Yunus. This study employs qualitative analysis to illustrate an architectural overview of the SB model by collecting secondary data from various publications related to the topic and published data of Grameen Bank. Finally, this paper illustrates the SB model along with specified characteristics, systematic framework, and main approaches for sustainable context, which could be applied as a conceptual framework for SB in any context of the emerging economy. The findings of this study suggest that the SB model is the workflow having a hierarchy of five phases namely need identification, goal setting, solution-based business plan, business plan assessment, and business plan execution. Analyzing a range of social business interventions in a developing country, Bangladesh, through the lens of five key aspects demonstrates that social business is the most efficient way to sustainably maximize the social benefits and minimize specific social issues poverty of the people affected.

Purpose: This study aimed to identify factors affecting the mental health status of children from multicultural families in South Korea. Methods: This study was based on Dahlgren and Whitehead's (1991) rainbow model as a conceptual framework and used data from the second phase of the multicultural adolescents panel study conducted by the National Youth Policy Institute. Multiple logistic regression analysis was performed using SPSS version 26.0, with p<.05 considered to indicate statistical significance. Results: In the final model, stress (odds ratio [OR]=0.53, p<.001), life satisfaction (OR=2.09, p=.004), self-esteem (OR=1.73, p=.032), and peer support (OR=1.46, p=.019) affected the mental health status of children from multicultural families. The living and working conditions and general socioeconomic, cultural, and environmental conditions did not significantly influence the mental health status of children from multicultural families in the final model. Conclusion: As components of Dahlgren and Whitehead's model, individual hereditary and lifestyle factors, as well as social and community networks, affected the mental health status of children from multicultural families. Therefore, in order to improve the mental health of children from multicultural families, efforts are needed to alleviate their stress, increase life satisfaction and self-esteem, and strengthen their social support.

Purpose: The purpose of this study is to construct and test a structural model for the Post-traumatic Growth (PTG) of police officers. The conceptual model is based on Calhoun and Tedeschi's PTG theory. Methods: Data were collected from 269 police officers working at 10 police stations in Seoul from September 26 to October 9, 2017. The exogenous variable was traumatic experiences, and endogenous variables were pain perception, self disclosure, social support, deliberate rumination, and PTG. The collected data were analyzed in order to calculate the direct and indirect effects of factors affecting PTG using SPSS/WIN 23.0 and AMOS 21.0. Results: The hypothetical model showed a good fit to the data: 𝑥²/df=2.57, GFI=.90, CFI=.95, TLI=.91, RMSEA=.07, SRMR=.07. The hypothetical model showed a similar result with the data, and out of 10 paths, 7 were statistically significant. The model explained 36% of the variance in the PTG of police officers. The model confirmed that social support and deliberate rumination had a direct effect, and that self-disclosure had an indirect effect on police officers' PTG. Conclusion: Nursing intervention programs to increase PTG of police officers should focus on deliberate rumination, social support, and self-disclosure. In addition, they should be accompanied by various crisis managements and consultations that can promote PTG.

근래에 들어 자연환경의 복원은 우리나라의 하천 관리에서 중요한 계획과제의 하나이다. 계획과정에 있어서 경관의 분석과 평가는 보전 지역 및 개발 지역의 적지선정을 위하여 매우 중요한 단계이다. 이 연구의 목적은 생태경관 단위에 있어서 생태환경분야별 조사 특성을 반영할 수 있는 위계적 방법론의 수립과 이에 기초한 적지분석을 통해서 하천내 보전 지역을 설정하는 데 있다. 경관 평가 과정에서 경관 스케일은 광역스케일, 지역스케일, 국지스케일로 구분하여 적용할 필요가 있으며, 이에 따라 환경자료들이 수집, 분석, 종합된다. 이러한 3단계의 단위개념이 도입되어야 하는 것은 하천코리도에서 보전지 설정을 위해 생태 자료들의 다원적 성격을 평가하기 위한 것이다. 위계적 스케일에 따른 평가과정은 3단계로 구분되어 수행되었다. 첫 번째는 장거리 경관 단위로서 광역적 개념에서 하천폭을 기준으로 설정되었다. 두 번째는 각각의 장거리 경관 단위의 지역적 개념에서 경관의 동질성을 기준으로 2이상의 단위공간으로 구분되었다. 세 번째는 국지적 개념에서 교각, 다리, 보의 위치에 따라 세분적으로 분류되었다. 이 마지막으로 분류된 국지적 단위를 기준으로 하여 생태환경에 대한 자료를 재취합, 분석하기 위한 개념적 적지분석모형의 항목들을 선정하였다. 최종 결과에서는 하천 내 습지생태학습공간으로서 집중적으로 관리되어야 할 잠재력이 있는 장소로서 3개소의 보전 지역이 설정되었다. 적지분석과정이 내포하고 있는 많은 가정에도 불구하고, 이러한 방법론적 제안은 우리나라의 하천복원계획에서 다원화된 전문가들과의 공통적 토론을 통해 생태 정보들을 통합하여 실천적으로 적용할 수 있는 틀을 제공할 수 있으리라고 기대한다.

Existing models of knowledge processing do not feature a systemic meaning of knowledge management and ignore the role of leadership and social energy in the knowledge processing system (KPS). This conceptual paper introduces the Leadership Invigorating Flows of Energies, (LIFE) Model as an attempt to remedy that situation and provide a more useful description of the KPS. The LIFE Model highlights the role of emergent leadership and flows of social energies as forces encouraging knowledge creation and dynamic diffusion within an organization through the Knowledge Processing Cycle in eight activities interacting with its social knowledge base in a self-organizing system.

Purpose: This research aims to verify the role of mobile shopping attributes, trustworthiness, and cultural dimensions on mobile shopping intentions in Saudi Arabia. The originality of the model stems from the verification of the moderating impact of cultural variables, namely collectivism and masculinity, and from the integration of trustworthiness as a variable depending on mobile shopping attributes. Research design, data and methodology: A survey was distributed to 233 consumers with different nationalities living in the Kingdom of Saudi Arabia. Structural equation modeling and multi-group analysis were carried out to verify the conceptual model and the moderating variables. Results: The findings support the influence of several innovation attributes, namely complexity and trialability on behavioral intentions, while relative advantage has a direct impact on trustworthiness. A few paths are moderated by masculinity and collectivism. Conclusions: Culture and mobile commerce attributes need to be thought out by managers as factors influencing mobile commerce segmentation for expatriates and locals. Trustworthiness is also a key factor of mobile shopping adoption. Limitations and future research ideas are presented to enrich the proposed model and improve its predictive validity.

The relationship between areal total phosphorus(TP) and areal hydraulic loading was identified and used as defining the trophic state of the reservoir. And three simple, conceptual TP models were tested against the measured in-reservoir TP concentration. The analyses were based on water quality data measured in the Ki Heung reservoir for two years. The results showed that Ki Heung reservoir has undergone eutrophic state, and Dillon's and Vollenweider's TP models were in close agreement with the measured annual mean TP concentration. However, the OECD's model understimated the measured annual mean TP concentration in the Ki Heung reservor. A discussion is given for the hypothetical application of TP loading plot which might be useful for establishing the TP control program in the resavoirs/lakes.

Recently, Service Level Management(SLM) including SLA has been developing to manage the level of information systems service. Although previous SLA studies have provided the conceptual model and critical success factors, the studies have not tested the effectiveness of the SLA by way of the empirical study. In this study, we applied an innovation decision making theory to our model and tested an empirical study using of a firm survey data. We suggested a SLM model, which consists of SLA planning, application, management dimensions. We found that the SLM's management stage has an impact on performance, whereas SLM's planning and application has not. At each sub dimensional analysis, there are found that adequate SLA indicators in the application stage influences performance and change management and feedback & reporting in the management stage influence performance.
