In this study, 1 dependent variable and 9 independent variables were established to examine suitable illuminance by spaces in urban parks in consideration of night users' psychological reactions and activity types. Such fixed variables were evaluated by a series of experiments of changing illuminance, and correlation among those variables was verified by correlation analysis and multiple regression analysis to suggest suitable illuminance by spaces. The results of this study are as follows: 1) The independent variables influencing suitable illuminance by spaces in urban parks were directly influenced rather by the psychological reaction of night users than the activity types by spatial functions. 2) Securing suitable illuminance by spaces commonly increased spatial availability, created certain atmosphere, and provided safety in the psychological reaction of night users. 3) Suitable illuminance by spaces in urban parks is: Central square is 31.88lx, resting space 6.30lx, exercising space 33.14lx, children's playground 14.19lx, pedestrian road 12.29lx, entry space 16.30lx, and green space 7.03lx. That is, when a place had more positive activities, spatial illuminance was increased. 4) Though comparison by spaces with the illuminance standard for urban parks as mentioned in KS A 3011-1993 can not be made, such illuminance was relatively compatible with the permissible range of illuminance in the author's opinion. It is expected that this study investigating suitable illuminance by spaces for night use in urban parks, will provide necessary knowledge for securing suitable illuminance by spaces in urban parks through classifyingin detail the illuminance standard of KS A 3011-1993. Besides, by helping make us aware of the importance of illuminance in urban parks as well as of external space in the night, this study will contribute to academic research and development in the field of landscape architecture and associated fields and be utilized in establishing legal and institutional standards.

Competency-based medical education (CBME) is an outcome-oriented curriculum model for medical education that organizes learning activities and assessment methods according to defined competencies as the learning outcomes of a given curriculum. CBME emerged to address the accountability of medical education in response to growing concerns about the patient safety in North America in the 1970s, and the number of medical schools adopting CBME has dramatically increased since 1990. In Korea, CBME has been under consideration as an alternative curriculum model to reform medical education since 2006. The purpose of this paper is three-fold: (1) to review the literature on CBME to identify the challenges and benefits reported in North America, (2) to summarize the process and experiences of planning and implementing CBME at Inje University College of Medicine, and finally (3) to provide recommendations for Korean medical schools to be better prepared for the successful adoption of CBME. In conclusion, one of the key factors for successful CBME implementation in Korea is how well an individual school can modify the current curriculum and rearrange the existing resources in a way that will enhance students' competencies while maximizing the strengths of the school's existing curriculum.

Concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) were determined in marine sediments from Mokpo coastal water of Korea. Total and toxic equivalent (TEQ) concentrations of PCDD/Fs ranged from 19.4 to 175pg/g dry weight and ranged from 0.195 to 2.87 pg WHO-TEQ/g dry weight, respectively. These PCDD/F concentrations were below the safety sediment value (20 pg TEQ/g dry weight) of chronic toxicity. A highly significant correlation between the concentrations of PCDD/Fs and total organic carbon (TOC) in marine sediments was observed. Overall PCDD/F concentrations in the sediments were elevated in rivers and at inner locations close to harbors, indicating that these contaminants derived from local discharges of human activities. PCDD/F concentrations measured in our study were lower than those in several industrialized areas in Korea. Nonparametric multidimensional scaling (MDS) ordination showed that combustion processes from industrial complexes are the major source of PCDD/Fs in Mokpo coastal water.

It is not surprising that senior centers are widely used nationwide as Korea becomes an aging society. This study attempts to figure out senior citizens' needs and evaluations of senior centers in terms of characteristics of their usage and spatial composition. A face to face interview using a questionnaire was conducted on 255 senior citizens who has been using senior centers located in Jangyu new city apartment housing complex. The questionnaire is composed of questions asking characteristics of their usage, evaluations of spatial composition, and respondents' demographic data. Findings are: First, it is found that many respondents visit senior centers everyday and spend 4 to 6 hours a day. Their main activities are meeting friends, taking hobbies, and dining. That is, senior centers play a pivotal role in daily lives of senior citizens. Such characteristics should be taken into account in space design when planning to build a future senior center; Second, it is found that senior centers play a role of auxiliary space for building their sense of belonging and familarity. It is found that furnitures in senior centers are worn out and safety measures are not sufficiently considered; Third, it is found that they highly evaluate flexible spacial composition that could be partitioned or extended depending on occasions even though they prefer independent space; Fourth, it is found that kitchen facilities are not large enough considering the fact that more that half of the respondents have their lunches in senior centers. Even though they do not cook for themselves kitchen space should be large enough for preparing meals simultaneously for a large number people.
