On the conflict factors in using community fishing ground and their solutions, some conclusions are derived with the survey for fishing villages, residents, tourists as follows: Jeju Island has beautiful sceneries with seas in all the directions and so remarkable potential as personal experience fishing village. For sustainable development of ecological tourism in each fishing village, systematic, long-term development plans and management systems through decision making with residents in fishing and non-fishing villages are demanded. For tourist development of fishing village, protection management systems for marine and swampy land are needed first of all. Next, economical profit and the participation of resident have first priority, and also individual standards for each village are urgently prepared based on the results of basic research on each village. Finally, educations on environment and fishing village with professional tourist guide are needed. Ecological protection, environmental education, resident participation, local government's concern, and financial support could solve residential conflicts and make Jeju Island a Mecca of local fishing village tourism.

복수 설비입지 문제의 한 유형인 컴퓨터 시스템 설치문제는 설치위치의 결정, 서비스 지역의 할본, 각 시스템의 규모 결정 등 복합적인 의사결정 과제를 안고 있다. 이 세가지 의사결정 문제는 상호 밀접하게 연결되어 있으므로 세 문제를 동시에 고려하여 전체적으로 최적화할 수 있는 해를 구하도록 해야하는 데 이는 매우 어려운 일이다. 그러므로 지금까지는 각각의 최적해를 독립적으로 구한 후 이를 적당히 결합한다거나 또는 아예 최적해를 구하기 보다는 만족할 만한 적정해를 구함으로써 만족할 수 밖에 없었다. 본 연구에서는 이러한 한계를 극복하기 위해 컴퓨터 시스템 설치에 있어서의 location-Size결정모형을 구축함으로써 이러한 의사결정 문제의 수리적 최적해를 구하고자 했다. 이 모형은 선형 및 비선형의 제약조건을 갖는 non-linear programming 문제로 수식화 되었으며, penalty function method, feasible conjugate, direction methods, branch & bound technique등의 algorithm들을 단계적으로 사용함으로써 최적해의 도출이 가능하게 되었다. 실제 문제에 적용한 결과 유용성은 충분한 것으로 보여졌으나 해법상의 개선을 통해 계산노력을 줄이도록 함이 요구 되었다.

This study focuses on the application of multi-criteria performance measures based on the concept of equifinality to the calibration of the rainfall-runoff model TOPMODEL in a small deciduous forest catchment. The performance of each parameter set was evaluated by six performance measures, individually, and each set was identified as a behavioral or non-behavioral parameter set by a given behavioral acceptance threshold. Many behavioral parameter sets were scattered throughout the parameter space, and the range of model behavior and the sensitivity for each parameter varied considerably between the different performance measures. Sensitivity was very high in some parameters, and varied depending on the kind of performance measure as well. Compatibilities of behavioral parameter sets between different performance measures also varied, and very few parameter sets were selected to be used in making god predictions for all performance measures. Since different behavioral parameter sets with different likelihood weights were obtained for each performance measure, the decision on which performance measure to be used may be very important to achieve the goal of study. Therefore, one or more suitable performance measures should be selected depending on the environment and the goal of a study, and this may lead to decrease model uncertainty.

Purpose: The purpose of this study was to identify university students' willingness to write advance directives and factors related to this willingness. Method: A cross-sectional survey design was used and 400 nursing students and 287 non-nursing students participated in the study. Data were collected by convenience sampling using self-report questionnaires. Data were analyzed with descriptive statistics, t-test, ANOVA, correlation, and multiple regression. Results: The mean score for willingness to write advance directives was 4.09. From the multiple regression analysis, predictors of willingness to write advance directives were found to be majoring in nursing, awareness of advance directives, preference for autonomous decision making related to the end of life care, family preference related to the end of life care, and self esteem. Conclusion: The study results indicate that various factors are related to willingness to write advance directives and nurses need to consider client characteristics, knowledge, and own values when taking care of issues on advance directives.

External fire spread has the potential to breach vertical compartmentation and violate the fire safety strategy of a building. The traditional design solution to this has been the use of non-combustible materials and spandrel panels but recent audits show that combustible materials are widespread and included in highly complex systems. Furthermore, most jurisdictions no longer require detailing of spandrel panels under many different circumstances. These buildings require rapid investigation using rational scientific methods to be able to adequately classify the fire risk. In this work, we use an extensive experimental campaign of material-scale data to explore the critical parameters driving upward flame spread. Two criteria are outlined using two different approaches. The first evaluates the time to ignition and the time to burnout to assess the ability for a fire to spread, and can be easily determined using traditional means. The second evaluates the preheated flame length as the critical parameter driving flame spread. A wide range of cladding materials are ranked according to these criteria to show their potential propensity to flame spread. From this, designers can use conservative approaches to perform fire risk assessments for buildings with combustible materials or can be used to aid decision-making. Precise estimates of flame spread rates within complex façade systems are not achievable with the current level of knowledge and will require a substantial amount of work to make progress.

Models of traditional Chinese medicine (TCM) are still difficult to grasp from the view of a Western-cultural background. For proper integration into science and clinical research, it is vital to think "out of the box" of classical sciences. Modern sciences, such as quantum physics, system theory, and information theory offer new models, that reveal TCM as a method to process information. For this purpose, we apply concepts of information theory to propose a "Chinese black box model," that allows for a non-deterministic, bottom-up approach. Considering a patient as an undeterminable complex system, the process of getting information about an individual in Chinese diagnostics is compared to the input-process-output principle of information theory and quantum physics, which is further illustrated by Wheeler's "surprise 20 questions." In TCM, an observer uses a decision-making algorithm to qualify diagnostic information by the binary polarities of "yang" (latin activity) and "yin" (latin structivity) according to the so called "8 principles" (latin 8 guiding criteria). A systematic reconstruction of ancient Chinese terms and concepts illuminates a scattered scientific method, which is specified in a medical context by Latin terminology of the sinologist Porkert [definitions of the Latin terms are presented in Porkert's appendix [1] (cf. Limitations)].

The vehicle routing problem is one of the vibrant research problems for half a century. Many studies have extensively studied the vehicle routing problem in order to deal with practical decision-making issues in logistics. However, developments of new logistics strategies have inevitably required investigations on solution methods for solving the problem because of computational complexity and inherent constraints in the problem. For this reason, this paper suggests a simulated annealing (SA) algorithm for a variant of vehicle routing problem introduced by a previous study. The vehicle routing problem is a multi-depot and multi-trip vehicle routing problem with multiple heterogeneous vehicles restricted by the maximum permitted weight and the number of compartments. The SA algorithm generates an initial solution through a greedy-type algorithm and improves it using an enhanced SA procedure with three local search methods. A series of computational experiments are performed to evaluate the performance of the heuristic and several managerial findings are further discussed through scenario analyses. Experiment results show that the proposed SA algorithm can obtain good solutions within a reasonable computation time and scenario analyses show that a transportation system visiting non-dedicated factories shows better performance in truck management in terms of the numbers of vehicles used and trips for serving customer orders than another system visiting only dedicated factories.

This study investigates the effect of chief executive officers (CEO) demographic characteristics such as age, functional experience, education, and gender, on corporate leverage decisions. This study investigates the independent commissioner's role in moderating the relationship between CEO demographic characteristics and leverage decisions. The data used is panel data with a sample of 283 non-financial companies listed on the Indonesia Stock Exchange (BEI) from 2010-2017. Moderated regression analysis is used as an analytical technique, with the selected model fixed effects model. The results showed that male and young CEOs were more risk-averse, so they tended to use debt more. However, this study found no evidence of the effect of CEO experience and education on leverage. This study finds evidence that independent commissioners reduce the influence of CEO age and gender on leverage decisions. It shows the role of independent commissioners in controlling risk-taking from male and young CEOs related to leverage decisions. These results become input for companies to consider demographic characteristics in choosing a CEO. Also, companies need a board (in this study seen from independent commissioners) that is strong enough to control the CEO regarding risky decision making, such as leverage decisions.

This research empirically analyzed whether the foods which came from a non-Muslim majority country, such as South Korea, could play an important role in affecting the consumer intention in a predominantly Muslim country. Online survey methods were used to investigate the proposed hypothesis. 318 responses were used for further analysis. Forty-six reflective constructs were adapted from literature and designed by using a five-point Likert scale to facilitate measurement. Estimation models and structural models were examined through SEM-PLS analysis techniques using SmartPLS 3.0 application as the data processing tool. The results showed that religiosity and halal awareness had a positive and significant effect on attitude toward halal labels, including the mediating effect from consumer attitudes towards halal labels which had a positive but insignificant effect on purchase intention. Halal awareness plays an important role for Muslims in the decision-making process for purchasing food. In contrast to the initial hypothesis, the country of origin actually did not have a positive effect on attitudes towards the halal label. In a Muslim-majority country like Indonesia, findings halal food is not difficult, so this research basically is a reminder to marketers to follow those halal principles in implementing their marketing strategies.
