The purpose of this study is to understand the daily lives of adolescents during the COVID-19 pandemic and to provide educational implications for enhancing the competencies of adolescents living in rapidly-changing environments. To this end, the photovoice method, consisting of orientation, documentation, discussion, and analysis, was employed to study nine adolescent participants, who were interested in sharing aspects of their daily lives. The results yielded four themes and nine sub-themes. The first theme is "home life", which is composed of two sub-themes: most comfortable to be alone and EA (eating alone) for lunch. The second theme is "leisure life", which consists of two sub-themes: the virtual world of playing with friends and exercise is the only way out to breathe. The third theme is "school life", which consists of three sub-themes: time for inner exploration and reflection, cracks in daily life due to excessive autonomy, and pros and cons of virtual classes. The fourth theme is "the voice of adolescents", which consists of two sub-themes: requiring adults to set a golden example and anxious voices due to an uncertain future. This photovoice method of study is meaningful in that it explores the daily lives of adolescents during the COVID-19 pandemic and provides valuable educational implications.

Many cities in the world have increased initiative to realize smart tourism. There are unexplored challenges for the people which lead and manage smart tourism projects and realize its value in tourism (we call them as 'Smart tourism initiatives'), such as orchestrating of tourism complexity, developing and sharing tourism strategy, sustaining tourism projects and innovation. Concerning these challenges, we aim to design a holistic capability maturity model for sustainable and smart tourism governance enabling sustainable tourism innovations via tackling the challenges above. We adopted Dynamic capability theory as a theoretical lens and introduced Design science research methodology in order to develop a new capability maturity governance model as a design artifact. As a result of the study, we could synthesize findings from iterations of the design research cycle based on the IT Capability Maturity Model. Our result proposes a potential capability maturity model supporting effective communication and strategic alignment for the initiatives with illuminating future paths with evaluation methods on tourism capabilities for the initiatives. Throughout this study, we contribute to the body of knowledge as well as practice by proposing a new tourism capability governance model.

지식근로자가 증가하고 정보의 종류가 다양해지며, 조직 간 정보의 교환이 빈번해질수록 기업 내부 정보관리시스템에 의존한 분석은 더 이상 효과적이거나 유용하지 않다. 이와 관련하여, 내부 지식정보시스템 뿐만 아니라, 외부의 정보공유시스템을 활용하는 방안이 최근 더욱 중요한 화두로 떠오르고 있다. 하지만, 조직 내외부의 정보공유시스템 사용에 대한 학문적 연구가 많지 않을뿐더러, 그 정보를 이용하는 사용자의 심리상태나 의도를 파악하는 연구는 거의 전무한 상황이다. 본 연구는 조직 내 지식관리시스템은 물론, 외부의 정보공유시스템을 이용하는 사용자 집단을 대상으로 심층 인터뷰 및 키워드 분석을 실시하여 그들이 가진 정보를 공유하려는 의도와 그 요인을 관찰하였다. 조사 결과, 내부 정보공유의 경우, 조직 내부에서의 업무와 관련된 정보를 공유하고 내부 구성원들 간의 소통을 원활하게하기 위한 목적이 대부분인 반면, 외부 정보공유시스템을 사용하는 목적은 자신이 보유한 정보를 공유함으로써 얻는 자기 만족감과 가치 있는 정보를 제공했다는데서 타인으로부터 얻는 신뢰감, 정보를 공유하는 행위로부터 얻는 순수한 희열과 같은 내재적 동기가 주로 반영되었음을 확인할 수 있었다. 본 연구를 통해 사용자들의 관심분야, 업무 관련성, 사용자 맞춤UI, UX의 개발, 구성원 간의 다양한 소통을 위한 커뮤니케이션 도구의 개발 등이 매우 중요하다는 실무적 함의를 도출하였다.

When a channel is vertically separated, there can be inefficiencies, double marginalization. Channel coordination to amend this inefficiency has been an important issue in marketing and economics. Channel coordination deals with maximization of joint profit and achieving proper profit sharing among participants. In this paper, a manufacturer and heterogeneous multiple retailers with exclusive territory are assumed, and channel coordination with two-part tariff is considered. When multiple heterogeneous retailers are assumed, profit sharing can be an issue even though the tariffs based on marginal cost can maximize joint profit. In case of multiple heterogeneous retailers, the manufacturer earns the same profit (fixed fee) from each retailer. This means that a large retailer occupies all the gaps of channel profit between small and large markets. Then, the manufacturer, which generally plays the role of Stackelberg leader, will consider increasing fixed price or marginal price to earn more profit from large retailer. Those reactions can sacrifice maximization of joint profit by making small retailer withdraw or by changing the sales quantities. In this paper, to maximize joint profit and achieve proper profit sharing, two kinds of optional tariffs are considered. The first is an optional two-part tariff based on marginal cost and the second is an optional modified two-part tariff in which marginal prices are higher than the manufacturer's marginal cost. In both types of optional tariffs, maximization of joint profit in each market can be achieved. Moreover, optional tariffs alleviate the problem of profit sharing. Optional tariffs can provide a manufacturer more profit from a large retailer when profit from a small retailer is given. However, the analysis shows that the maximum share of manufacturer from a large retailer is restricted by the condition for self-selection. In case of optional two-part tariffs based on marginal cost, if the gap between demands is large, the maximum share of the manufacturer is sufficient to achieve proper profit sharing. If the gap between demands is not sufficiently large, the manufacturer cannot earn sufficient share from increased profit. An optional modified two-part tariff where marginal price is more than marginal cost of manufacturer is considered because of this scenario. The marginal price above the marginal cost may additionally control the distribution of the increased profit. However, the analysis shows that a manufacturer's maximum profit from a large retailer with given profit from a small retailer is the same as or lower than the maximum profit when optional two-part tariffs based on marginal cost are applied. Therefore, it can be concluded that the optional modified tariffs do not have additional contribution to profit sharing relative to the tariffs based on marginal cost. Although this paper does not cover all kinds of optional tariffs that are different from tariffs based on marginal cost, it shows the advantage of optional tariffs based on marginal cost and has important theoretical implications. The result of this paper also gives guide for channel coordination. Optional two-part tariff based on marginal cost can increase efficiency in channel coordination.

The main purpose of the research was to prove, in a practical sense, the relationship among perceived equity, role stress and life satisfaction of employed wives working in sales departments. The subjects were employed wives working in sales departments who have at least one child and a spouse, living in Seoul and the Metropolitan area. The final data analysis used 487 out of 668 questionnaires. Statistical analyses were carried out using SPSS/PC WIN which included frequencies, mean, percentages, Pearson's correlation, Cronbach's ${\alpha}$, factor analysis, multiple regression analysis. The findings of the study were as follows: 1) As their education level was low, the education level of their spouse was high, the communication level between couples was high, and the self-oriented perfectionism was low, their perceived emotional relationship was equal. As they were old, the communication level between couples was high, and the self-oriented perfectionism was low, their perceived position in sharing household chores was equal. On the other hand, as they were younger, the education level of their spouse was high, the reason for getting a job lay in supporting the family, and overtime hours worked, there was a higher level of role stress. 2) The influential variables which affect the life satisfaction, in order of importance, were communication level between couples, mother's role stress, age, non-financial reason of getting a job, and sharing household works. For relative contribution degree about life satisfaction, psychological variables among independent variables were revealed as the most influential ones. Thus, efficient communication between couples affected the life satisfaction to a great degree. Furthermore, the study proved that not only role stress variables but also perceived equity variables contributed to the life satisfaction.

TThe cooperation on disaster prevention between the two Koreas has been mostly focused on cooperation at the recovery stage, such as emergency relief supplies and equipment support. This study aims to articulate future practical development plans by analyzing disaster cooperation between North and South Korea in accordance with the changing paradigm of international disaster cooperation. Considering the specificity of inter-Korean cooperation, the Framework for Inter-Korean Disaster Prevention Cooperation was established centering on the Sendai Framework for Disaster Risk Reduction. The framework consists of understanding and sharing disaster risks, building back better, strengthening community resilience, and supporting regional disaster action plans for continuous action. Inter-Korean disaster prevention cooperation requires sharing information about North Korean disasters. It is necessary to accurately identify and support social vulnerability to North Korean disasters. Above all, it is supporting the development of disaster action plans from a humanitarian perspective needs. A medium-to-long term resilience reinforcement plan that North Korea can resolve on its own is also needed. Since North Korea is also deeply interested in international disaster cooperation, it should be based on the direction of the Sendai Framework. Considering the uniqueness of inter-Korean cooperation, a path for North Korea to actively participate in international disaster cooperation should be established.

Changes in marketing environment have made it feasible for functions and roles of marketing subjects who participated in marketing routes to be changed. However, there has not been a study to prove it or to deal with newly required functions. Hereupon, this study has specifically investigated and analyzed marketing functions and performance on marketing associates for seafood in Busan in order to identify how marketing functions influenced on marketing performance. Marketing function might differently influence on the performance depending on the difference of business type. Results of verifying the hypothesis are as follows. As for variables that influenced on wholesaler groups, marketing, product development+investment, information-sharing, and trade functions turned out to be influential. Among wholesaler groups, marketing, sorting, collection, market frontier+product development, integral distribution, information-sharing, and finance functions turned out to be influential. In addition to these basic results, another difference industries, restrictive range of activities, the differences in handling goods, such as by correspondence of the results to changes in the distribution environment, from the results of the present study it is possible to guess.

The minimum royalty should have two objectives. One is to guarantee the minimum license payment and the other is to screen the eligible licensee to prevent the licensee`s strategic behavior. In the licensing contract for public-to-private technology transfer, the latter plays more important role than the former in viewpoint of the successful technology transfer and commercialization. However, the minimum royalty falls into a dilemma to increasing the risk on the part of licensee in case of failure in technology transfer and commercialization. In our study, ex-post option contract will be suggested as a risk sharing mechanism to overcome above dilemma. The ex-post option contract means the contract which the licensee has the option whether to go or not at the time of manufacturing stage. To proof the usefulness of ex-post option contract, it is shown in the study that expected utility of a licensor and a licensee can increase with a certain constraint, which depends on degree of uncertainty and licensee`s risk aversion, after introducing the ex-post option contract. In spite of this constraint, the usefulness of ex-post option contract may be highly appreciated because its constraint is quite normal case in the real world.
