Objectives: We aimed to evaluate the effect of geographic units of analysis on measuring geographic variation in medical services utilization. For this purpose, we compared geographic variations in the rates of eight major procedures in administrative units (districts) and new areal units organized based on the actual health care use of the population in Korea. Methods: To compare geographic variation in geographic units of analysis, we calculated the age-sex standardized rates of eight major procedures (coronary artery bypass graft surgery, percutaneous transluminal coronary angioplasty, surgery after hip fracture, knee-replacement surgery, caesarean section, hysterectomy, computed tomography scan, and magnetic resonance imaging scan) from the National Health Insurance database in Korea for the 2013 period. Using the coefficient of variation, the extremal quotient, and the systematic component of variation, we measured geographic variation for these eight procedures in districts and new areal units. Results: Compared with districts, new areal units showed a reduction in geographic variation. Extremal quotients and inter-decile ratios for the eight procedures were lower in new areal units. While the coefficient of variation was lower for most procedures in new areal units, the pattern of change of the systematic component of variation between districts and new areal units differed among procedures. Conclusions: Geographic variation in medical service utilization could vary according to the geographic unit of analysis. To determine how geographic characteristics such as population size and number of geographic units affect geographic variation, further studies are needed.

Studies in key account management (KAM) have identified the importance of cross-functional coordination in firms to effectively implement KAM. However, these studies have ignored how companies integrate KAM and other customer management (non-KAM). This paper explores coordination design between KAM units and non-KAM units by analyzing a case study through three dimensions: front-end coordination, back-end-coordination, and organizational translation at the beginning of research. The case study shows that non-KAM conditions can require a modification of the coordination design. This research performs an in-depth analysis of changes in the implementation of sales reforms for an IT-related machinery and system vendor in Japan. Data sources include interviews with KAM units and non-KAM sales units and an analysis of secondary data. This paper suggests that studying the coordination between KAM units and non-KAM units will further our understanding of internal coordination in KAM research.

A reliability model of Level II AFDA is developed to analyze the stability of armor units on the sloped coastal structures. Additionally, the partial safety factors of random variables related to armor units can be straightforwardly evaluated by applying the inverse-reliability method in which influence coefficients and uncertainties of random variables, and target probability of failure are combined directly. In particular, a design equation for armor units is derived in terms of the same criteria as deterministic design method in order to apply the reliability-based design method of Level I without some understanding to the reliability analysis. Finally, it is confirmed that several results redesigned by the reliability-based design method of Level I have satisfactorily agreement with results of CEM as well as those of Level II AFDA.

The purpose of this study is to provide a basic data for energy efficient apartment designs by analyzing electricity and gas usage according to horizontal locations of dwelling units in apartment buildings. The data for this research are collected from J-apartment complex, located at 'Wolbae' district in Daegu City. The data are sorted into several groups according to inner and outer locations, East-West locations, and the size of units. By the performance efficiency analysis, the study derives the result as follows: 1) generally inner units are more efficient than outer units. 2) West units are more efficient than East units. 3) The group that is most efficient in overall energy consumption is West-inner units (Group-D) and the least efficient group is East-outer units (Group-A1). 4) However, as units are getting bigger, inner units consumes more energy than outer units because of the gas usage patterns. The study also established cost analysis that shows the cost differences of usages for 30, 40, 50 years between each group. The result says Inner-outer location with East-West location affects a significant amount of the management costs. In terms of economic and social life of an apartment building, energy design standards need to be tuned and make the least efficient units perform as efficient as the most efficient units to optimize the social life of an apartment building.

The purpose of this study was to examine the consistency and balance of learning objectives of units and instructional units according to grades and educational domains. Educational domains were cognitive(scientific knowledge), scientific inquiry(inquiry process skills), affective(scientific attitude), and science-technology-society(STS). Learning objectives of life field of the 7th elementary science curricular teaching guidebooks were analysed. Scientific inquiry process skill objectives(43.5%) were most dominant in units, but cognitive objectives(53.9%) were most dominant in instructional units. STS objectives were most recessive in both units and instructional units. Especially, objectives of units and instructional units were shown no consistency by grade. The results of this study suggested that the textbooks and teaching guidebooks should be developed consistently by considering learning activities and contents on the basis of background and properties of science curriculum.

The purpose of this study is to unveil the characteristics of residential space organizations in dementia units. Observation, interview, and drawing analysis of the sample units were used to collect the data for new dementia unit plans. The findings revealed the lack of minimum requirement of residential spaces per person in some sample units, the necessity of consideration of group units, and the change of units based plans to each floor based plans. However, insufficient recreation rooms and the lack of caregivers' resting spaces in the sample units were uncovered. Thus, various recreation rooms such as a reading room, flower room, pottery room, bakery room, or game room should be provided in the sample units. The conclusion is that asylum oriented residential types should be changed to each floor based units having privacy and high satisfaction of residential life. The study of floor oriented residential units focusing on minimum spaces of the floor, space numbers, number of elderly persons on each floor should be studied in the near future.

Modular construction is an economical and efficient construction that reduces time and costs by manufacturing units in factories and constructing them on site. Currently, the demand for modular construction is increasing not only abroad but also domestically. As the demand for modular construction increases, a lot of development and research on connections between modular units are being conducted. Connections between modular units should be quick and simple to assemble when assembling units on site, and should be in a form that allows each unit to be connected regardless of direction. In addition, it must be able to exert sufficient strength against external loads. In this study, a connection between modular units using connecting steel plates and bolts was proposed, and the nonlinear behavior of the connection to external lateral force was analyzed through finite element analysis, and resistance performance was evaluated.

In this paper, we proposed comparison of software education units according to 2015 Revised National Curriculum. Comparative analysis of 6 Practical Arts textbooks was conducted especially on the software education units. The analysis criteria were decided to be unit system, unit structure, learning objectives, the way of placing contents, activities, supporting materials, providing resources, and evaluation. As a result, the software education units have secured a lot of quantity compared to the total number of units. And the affective domain of the learning objectives is shown to be lacking. All the textbooks were uniformly arranged the component of contents described in 2015 revised national curriculum. Cooperative activities are strengthened compared to the previouse curriculum. On the other hand, evaluations have a large variation among textbooks and some have fewer types.
