This study examined the effects of wildlife or wildlife species on national park visitors' perception of place attributes and recreational experiences. Data were collected from 502 users of Seongsamjae Rest area and Nogodan Shelter area in Jirisan National Park and 173 college students during May-June 2014 using survey questionnaire. Some simulated photographs of water deer and Asiatic black bears were used for the college student survey. Overall, awareness about wildlife inhabiting in Jirisan National Park (AW) was not related with one's perception of place attributes (PPA) (i.e., crowdedness, naturalness, safety) and types of visitors' recreational experiences. Respondents with higher awareness about the presence of Asiatic black bear (AABB), however, tended to perceive Jirisan National Park as a place that provides 'wild' or 'natural' recreational opportunities compared to those with lower AABB. Differences in PPA (i.e., crowdedness, naturalness, safety) and types of recreational experiences were also found to be influenced by wildlife species. Respondents exposed to bear or water deer tended to perceive their recreational experiences as more 'wild'. Existence of wildlife in Jirisan National Park had a positive effect on the quality of visitors' recreational experiences. Different wildlife species showed different levels of effectiveness to quality enhancement of recreational experience. Some practical implications of the study were discussed from a managerial point of view.

In the major operation section of urban railway, there has been occurred habitual delay, and delay propagation and spread to consecutive trains. Therefore, this delay cause the increase of operation time and irregular operation, also the increase of crowd and inconvenience to passengers. The railway operation plan is a promise to passengers and must have reliability. In the case of high frequency urban operation, dwell time have considerable influence on operational headway, so it is very important to efficiently plan and control the dwell time at stations. In this paper, the survey of the research on dwell time for urban railways is presented. The practical estimation model for minimum required dwell time, and the numerical example and validity are proposed.

The environmental conditions in smallholder dairy farms especially the effects of dairy wastes on waters and soil were the main objectives of this investigation. Forty-three dairy farms from an older dairy cooperative (Nongpho Dairy Cooperative, NP) were compared with four dairy fauns from relatively new dairy cooperative (Kamphaengsaen Dairy Cooperative, KS) for the quality parameters of water and soil samples during a 12-month period. Forty-three farms at NP were from three geographical areas and three levels farm crowdedness. The results from this study clearly showed that the waste waters from older dairy barns contained much higher levels of organic and inorganic substances which could create environmental pollution if not properly managed. The differences in waste water qualities due to areas and seasons were not significant, while waste water samples from crowded farms tended to contain higher averages of waste water parameters such as COD and BOD. Highly significant correlations between pairs of waste water parameters indicated that certain parameters can be used without the need for chemical analysis of some other parameters. The qualities of well water on dairy farms as well as water samples from public waterways nearby indicated some contamination of dairy wastes such as manure. Storage and sun-drying of dairy manure on bare soil surface could result in the contamination of underground water and nearby water sources. Some recommendations from this study if implemented can prevent environmental pollution in smallholder dairy farms.

This study was conducted during a period from July 4 to 30 to investigate the effect of restaurant environment upon customer's satisfaction and crowdedness awareness. Total 800sets of questionnaire were distributed among major food service corporations. They were 16 restaurants from McDonald, Burger King, Popeyes, KFC, Rits Carlton, Intercontinental, The Westin Chosun, Hilton, Merriot, Outback Steak House, Bennigans, VIPS, Pizza Hut Pul-hyanggi(Scent of grass), Nolboo Co.,, and Our Story, and received 50 see each to hand out to their customers. Out of total 800 sets of questionnaires, 592 sets (74.25% were retrieved and underwent a Multiple Regression Analysis. We found the following results from the study. First among each variable of restaurant environment that had a significant effect on the crowding, 'pTast service' and 'responsiveness to customer complaints' sooted a regression coefficient value 0.381 and 0.325 respectively. Second, among each restaurant environment factor that had a significant effect on crowding, 'quality of facility' sooted the highest regression coefficient value 0.423 with a standard error score 0.1074, fellowed by 'status of waiting', 'overall ambience' and 'service quality' in ascending order. Third, in the analysis of the effect of each environmental factor upon the satisfaction rate, 'status of waiting' showed the highest regression coefficient value 0.3821 with a standard error score 0.4565, followed by 'cleanliness', 'service quality' and 'conveniency', in ascending order.

Shopping malls in Korea have grown in size and number, and their one-stop convenience has expanded to include various retail stores, service outlets, and entertainment providers. This study closely examines the shoppers' experience in a shopping mall. Using the photo elicitation interview (PEI) method, this study aims to provide deeper understanding of the subjective perceptions and context of shopping mall users. Ten shopping mall users participated in this study. They visited a shopping mall and took photos from their points of view about the shopping experience, and later participated in a personal interview. Convenience, excitement, relaxation, and socialization are the major themes of a pleasant shopping mall experience. Crowdedness and ineffective store design are the major themes of an unpleasant shopping mall experience. Core contents of each pleasant and unpleasant theme are presented. Given the current retail environment where shopping malls are continuously expanding, understanding the behavior and perception of consumers related to shopping malls is important in designing and providing a compelling experience in shopping malls.

To compare the physical quantity of students circulation along the moving path during recess of a variation type operation middle school, five points were actually observed. The flow coefficient for these points was calculated, and the change in flow coefficient was verified and tracked over time. During the operation of the classroom, the characteristics of crowdedness and congestion time depending on the physical conditions of the frequently moved paths were shown. Even in the same corridor, the difference between the flow coefficient and the congestion time of the corridor facing the open space and the blocked space was noticeably different. As a result, detailed factors such as free walking speed, the degree of freedom of passing and the possibility of collision were also identified. This means that detailed countermeasures for the student's path should be considered first when planning the moving space of a variation type school, and identifying the characteristics of these factors could be used as useful basic materials for developing various models of classroom space.

Vertical growth is viewed as the solution to the problem of urban housing. The present study aims to be multifocal in approaching the phenomenon of apartment living in Lahore, Pakistan. The primary focus of the research was to evaluate the satisfaction with and favorability of vertical living among the dwellers; however, the research was extended to include the in-depth experiences of adolescents regarding privacy because it was observed that this age group was being neglected severely in the distribution of privacy in apartments, as well as in research. The data was first collected from 150 respondents through a survey, and then interviews of 10 adolescents were conducted to explore notion of privacy. The findings highlight that, despite being satisfied with the infrastructural aspects of the building, the residents do not prefer vertical living over horizontal housing. The adolescents in apartments also prefer horizontal housing over vertical living to avoid the feeling of crowdedness that is associated with vertical growth due to shared space and proximity. The utilization of spaces within apartments is associated with certain elements of development of the personality during this age. The findings of the present study can be helpful for sustainable vertical housing policy development and implementation.

This paper proposes a novel two-tier optimization approach for decision making in many-objective problems. Because the Pareto-optimal solution ratio increases exponentially with an increasing number of objectives, simply finding the Pareto-optimal solutions is not sufficient for decision making in many-objective problems. In other words, it is necessary to discriminate the more preferable solutions from the other solutions. In the proposed approach, user preference-oriented as well as diverse Pareto-optimal solutions can be obtained as candidate solutions by introducing an additional tier of optimization. The second tier of optimization employs the corresponding secondary objectives, global evaluation and crowding distance, which were proposed in previous works, to represent the users preference to a solution and the crowdedness around a solution, respectively. To demonstrate the effectiveness of the proposed approach, decision making for some benchmark functions is conducted, and the outcomes with and without the proposed approach are compared. The experimental results demonstrate that the decisions are successfully made with consideration of the users preference through the proposed approach.

Objectives: Students in elementary schools usually wash their hands in a washstand. However, little attention is paid to the washstand itself. Today, the importance of personal sanitation and hygiene is greatly emphasized. Therefore students' parents and the public are growing increasingly interested in accessibility to washstands by elementary school students in their schools. Methods: With respect to this study, a survey of students and teachers inelementary schools was performed on the installation of washstands in order to determine the proper number of washstands per school. Results: The results show that 1.1 boys (per class) need a washstand, while 1.8 girls (per class) do so in order to maintain a 50% level of crowdedness. By of the regression equation, to maintain 50% congestion (50% of all students feel congestion) there should be 18.5 boys, and the 15.76 girls per washstand. Table 3 is based on the above results, the number of students per washstand (x) and congestion (y), separated by gender according to the results of regression analysis, the correlation of male models in the linear regression analysis and correlation of girls in the regression equation can be obtained. The linear regression fit of less than 0.7 determines that the coefficients of determination are 0.5399 and 0.4195, respectively. Significance was much smaller. Also, according to the simulation using the diffusion model, with 29 students per class more than one washstand should be provided in a school. Girls (per class) need 0.7 more washstands than boys (per class). Conclusions: More washstand facilities for girls than boys are needed. If the target is based on school class size two washstands should be installed. Finally, guidelines and/or standards in the Schools Health Act of Korea forin elementary school washstands is considerably needed.
