If we eat long time foods that don't suit our constitution, health is broken and we take a disease. Therefore, care of foods and taking medicine by constitutional notion have a object that is normal control of constitution. It is attained when we maintain an adequate balance of Jang and Bu(臟腑) organs functional deflection. Theory of SaSang constitution by Lee-Jae Ma provides us a proper base of theory. But, later foods and drugs classified by constitution, that is suggestied by many scholars, is some different. Therefore, it is doubtful whether choice of foods and drugs suitable to constitution is right. If we use foods and drugs suitable to constitution exactly, we can decrease a side effect arisen from unsuitableness. On this, I study by literatures in order to provide foundational data. Lee-Jae Ma classified four species constitution, I compared twelve literatures by constitution, classified profit and harmful foods, and arranged and classify drugs that literature writer suggests in common. On base of this study, I suggest that foods and drugs classified by constitution is as follows. 1. Lee-Jae Ma made SaSang constitution medicine, but didn't suggestied use of foods, therefore, commoness of foods constitutional classification must be arranged. 2. Also commoness of drugs constitutional classification must be arranged. 3. Other literatures must be compared and analyzed except those of this study, because I didn't analyze many SaSang literatures.

The recent global economic crisis has resulted in increased discussion and attention on the sharing economy, a form of economic activity where individuals share currently available products. This study investigates consumer sharing economy usage attitudes and usage intentions by applying rational choice theory. For this study, an investigation that had 400 adult consumers from across Korea answer a structured questionnaire was conducted. A statistical approach using SPSS ver. 22.0 was used to analyze the data. The study found that the consumer's sharing economy value and participation levels were higher than usual. Higher than usual consumption patterns were seen for the construct of rational behavior theory. An analysis of the relative influence of variables regarding sharing economy usage intention also found that usage intention was higher for those who had experienced using a sharing economy services rather than those who did not have experience. In addition, the sharing economy usage intention also increased along with the values for subjective norms, sharing economy usage attitudes, sharing economy participation, sharing economy emotional benefits, and increased values. This study found that fundamental materials for consumer education should be made to eliminate difficulties that consumers have when they use sharing economy services. It is also expected that economic policy will develop to stimulate the sharing economy in a stable manner, that sharing economy-related information will be provided to consumers, and that consumer policies will be prepared to prevent consumer problems before they occur.

This paper attempts to investigate the determinants of capital structure of Vietnamese firms and also shed light on some of the factors of the modern theory of capital structure which is relevant for explaining the capital structure in advanced countries which are also relevant in the context of Vietnam. Using panel data from more than 1000 Vietnamese listed enterprises census 2017-2020, the paper finds that leverage ratio of Vietnamese firms is significantly related to probability. The firms have high level of fixed assets which they use as collateral, resulting in higher debt ratio, which is in line with the pecking order theory. The result also confirm that highly targeted debt ratio is positively correlated with the industry characteristics (using real estate firms as a benchmark), in which firm operates. Furthermore, consistent with the trade-off hypothesis, the leverage ratio is positively affected by non - debt tax shield. The result confirms that a large number of companies are state - owned, will have an insignificant impact of firm's size (as reverse proxy for bankruptcy cost) on leverage ratio. We also find that there is no distinction between state-owned enterprises and private enterprises due to strict adherence to the rules set by the Vietnamese government. Distinct from other countries, corporate income tax has slight impact on capital structure in Vietnamese firms.

This study identified types of online retail internationalization in the fast-fashion context and proposed driving factors of retailers' choices in online-based market entry following the logic of the Uppsala model and the eclectic theory. In particular, this study proposes three types of online-based internationalization: 1) entering a host market with a physical store first, and then expanding with an online store, 2) entering a foreign market with an online store, then expanding to physical stores, and 3) entering only with an online business. In addition, this study investigated the causal factors, ownership-specific and location advantages, that influence the choice of the type of developmental process of online-based internationalization. To develop theoretical and managerial insights into the issue researched, this study employed a qualitative research design involving case studies of three European fast-fashion retailers, H&M, TOPSHOP, and ASOS. This study suggested that fast-fashion retailers that enter a host market with high ownership-specific advantages are likely to choose to enter the market with physical stores and then expand with online stores. On the other hand, when faced with uncertainties attributable to low ownership-specific or location advantages, fast-fashion retailers are likely to choose to enter with an online store first and then expand with physical stores as conditions change. Consequently, this study provides a better understanding for fast-fashion retailers who are willing to expand their businesses to foreign markets via online stores.

This study analyzed the decision-making process in ship finance for the choice between fixed and floating interest rates using behavioral finance theories. Results confirmed that causes and background of decision-making processes could be explicitly explained by the framework of behavioral finance theories. This study also determined whether decisions were irrational. A case-study research was applied as the methodology. Decision-making data on ship finance collected through narrative and questionnaire responses were analyzed and evaluated using behavioral finance theories. Theories of behavioral finance used in the analysis and research of this study included availability heuristic, anchoring effect, and opportunity cost theory. Narrative and survey responses were clearly explained by theories of behavioral finance. It was found that a shipping company suffered additional losses owing to decisions that included behavioral finance errors. Behavioral finance theories largely influenced the decision-making process of choosing between a fixed interest rate and a floating interest rate. Shipping finance decisions related to interest rate selections could be clearly explained by behavioral finance theories. Errors related to behavioral finance could result in irrational decisions. Thus, managers who are responsible for shipping finance should remain vigilant toward any behavioral finance errors when making shipping finance decisions.

Purpose: Understanding the distribution channel is a foundational element of successful hotel revenue management. This study aims to assess hotel distribution network partnerships and develops a model that can be utilized to ensure hoteliers are not becoming increasingly reliant on a single channel, optimize their market exposure, and maximize their portion of the overall worth of the network. Research design, data and methodology: This study utilizes a grounded theory approach to form a theoretical model by analyzing and examining the current practice of hotel distribution management through interviews with 15 stakeholders in Indonesia, such as hoteliers, online travel agents, wholesalers, and connectivity managers. Results: Based on data analysis, we describe hotel distribution elements, revenue team, managed channels, and channel prioritization for a different type of hotel. Finally, we propose a distribution channel model that comprises hotel teams, customer types, indirect channels, and direct channels. Conclusions: The model contributes to the literature by exploring the options of distribution channels for various hotel types to support hotel revenue management practice. By utilizing our model, practitioners can have a complete picture regarding the strategic choice of the channel by considering their hotel capacity and market target.

기존 연구에서는 이산화탄소의 한계저감비용을 추정할 경우 쌍대성 이론에 근거하여 임의로 설정된 하나의 방향성 벡터(directional vector) 설정하였으나 본 연구에서는 이러한 한계를 극복하고자 다양한 형태의 방향성 벡터를 사용하여 이산화탄소의 한계저감비용을 추정하였다. 기존의 방법론에서는 임의로 설정된 방향성 벡터가 한계저감비용 추정에 결정적인 역할을 하여 선택된 방향성 벡터에 따라 한계저감 비용 추정치가 상당한 차이가 있음을 알 수 있다. 그리고 $45^{\circ}$의 방향성 벡터를 설정하는 경우에는 실제 이산화탄소 배출량 수준과는 다른 배출량 수준에서의 한계저감비용을 추정하게 되지만 본 연구에서 제안한 방법론에 의하여 추정된 한계저감비용은 실제 이산화탄소 배출량 수준에서 한계저감비용을 추정하여 보다 더 현실을 정확하게 반영하는 추정치이다. 새로운 방법론을 서유럽 국가에 적용하여 추정한 이산화탄소의 한계저감비용은 기존 방법론을 사용하는 경우에 비하여 적은 것으로 추정되었다.

Rock is a heterogeneous material, which introduces complexity in the analysis of rock slopes, since both the existing discontinuities within the rock mass and the intact rock contribute to the degradation of strength. Rock failure is often catastrophic due to the brittle nature of the material, involving the sliding along structural planes and the fracturing of rock bridge. This paper proposes an advanced discretization method of rock mass based on block theory. An in-house software, GeoSMA-3D, has been developed to generate the discrete fracture network (DFN) model, considering both measured and artificial joints. Measured joints are obtained from the photogrammetry analysis on the excavation face. Statistical tools then facilitate to derive artificial joints within the rock mass. Key blocks are searched to provide guidance on potential reinforcement measures. The discretized blocky system is subsequently implemented into a discontinuous deformation analysis (DDA) code. Strength reduction technique is employed to analyze the stability of the slope, where the factor of safety can be obtained once excessive deformation of slope profile is observed. The combined analysis approach also provides the failure mode, which can be used to guide the choice of strengthening strategy if needed. Finally, an illustrated example is presented for the analysis of a rock slope of 20 m height inclined at $60^{\circ}$ using combined GeoSMA-3D and DDA calculation.

이 연구는 남북 공유하천의 바람직한 관리 비전과 목표를 수립하기 위해서 북한강의 임남댐 사례를 통해 합리적인 관리 전략을 세우는 것을 목적으로 한다. 방법론적으로는, 게임이론의 접근 방법을 통해 남북한 공유하천 문제의 해법을 찾아보았다. 기존의 논의가 주로 남북 간의 비협조적인 상황 하에서의 대응전략을 주요한 관심으로 한 데 비해 본 연구에서는 보상을 연계시킨 협조게임의 접근방법으로 남북 간의 협력의 가능성을 시나리오를 설정하여 분석하였다. 또 남북이 최선의 이득을 얻을 수 있는 협력과 보상의 조건을 계량화하여 평가할 수 있는 방법론을 제시하였다. 남북한이 모두 최선의 편익을 누리는 방법은 북한이 남한에게 유량을 할당해주고, 남한은 그에 대한 보상으로 남북 공동의 이익을 가져다 줄 수 있는 공동개발 사업(임진강 유역의 공동개발 등)에 적극적인 투자를 하는 방법이라고 할 수 있다.
