Although many studies have been conducted to extract buildings from airborne lidar data, most of them assume that all the boundaries of a building are straight line segments. This makes it difficult to model building boundaries containing curved segments correctly. This paper aims to model buildings containing curved segments as combination of straight lines and arcs. First, two sets of boundary points are extracted by adaptive convex hull algorithm and local convex hull algorithm with a larger radius. Then, arc segments are determined by average spacing of boundary points and intersection ratio of perpendicular lines. Finally, building boundary is modeled through regularization of least squares line or circle fitting. The experimental results showed that the proposed method can model the curved building boundaries as arc segments correctly by completeness of 69% and correctness of 100%. The approach will be utilized effectively to create automatically digital map that meets the conditions of the Korean digital mapping.

The expanded uncertainties calculated by the application of GUM -approximation and Monte-Carlo simulation were compared about the model equation of one-point calibration which is widely used for the measurements and chemical analysis. For the comparisons, we assumed a set of artificial data at the various level of concentration and dispersion of t or normal distribution. Mistakes of more then 50 % was revealed at the values calculated by GUM-approximation in comparison with those of Monte-Carlo simulation because of the excess dispersion from t-distribution and non-linearity by division in the equation. In contrary, the mistake of calculation due to non-linearity of the equation was not observed in the level of detection limits with the equation of one-point calibration, because of the relatively large values of uncertainty in response.

The purpose of this study was to investigate the effects of stress factors on fatigue and depression of aesthetician. The subjects of this study were 133 Aesthetician in Busan Metropolitan City. Analysis was done by frequency analysis, t-test, one-way ANOVA and regression analysis. The results of this study are as follows. First, the aesthetician showed an average 2.57 of job stress. Second, the aesthetician showed an average 2.45 of socio-psychological stress. Third, the aesthetician showed an average fatigue(4.16) and depression(1.54). Therefore, in order to reduce the duties and socio-psychological stress of the aesthetician, fatigue and depression are reduced through regularization of the employees, adjustment of legal working hours, and establishment of similar paying system. Finally, it is necessary to lower the turnover rate of the aesthetician and increase the job satisfaction.

This study analyzed 10,352 married women to find the correlation between marital equality felt by married women and additional childbirth intentions. Frequency analysis and chi-square test analysis were performed to analyze the general characteristics of the investigator, and studies were conducted through binary logistic regression analysis and interaction analysis to analyze the relevance between each variable and additional childbirth. As a result, the 4-point group based on the 0-point group that lowest marital equality had 2.01 times higher willingness to additional birth. And, the 3-point group and the 2-point group were 1.46 times and 1.41 times higher than 0-point group with marital equality and additional childbirth intentions. In addition, intention of additional childbirth was increased when the higher the number of children, if they own a house, and if wives are non-regular or unemployed. This study analyzed the relationship between married women's intention to give birth additionally, focusing on marital equality. It is suggested that specific and reasonable policies at the macro level are required to improve the fertility rate.

This practical study is to propose a model for efficiently implementing franchise management by Franchise Enterprise in franchise industry. Franchise system is established and mutual relationship is also fulfilled based on bilateral contract between franchisor and franchisee. After contract and opening the franchisee store, franchisees are continually supervised and administered according to mutually agreed process and procedures. In this regard, franchisor should have well-managed system for supervising and assisting franchisee efficiently and effectively. The purpose of this study is to set-up the concept of enterprise contract management(ECM) in Franchise Enterprise and to promote the systemization of franchise management, and also to present and propose the development tool for franchise-specific IT program which is called " Franchise Contract Management'Supervising System".

본 연구는 미래에 창업을 하고자하는 예비창업자에게 창업의도의 방향을 제시하기 위해 창업을 하기 전 자신을 알게 하고 정부지원과 교육의 필요성, 중요성을 일깨워주는 연구로 실증적으로 조사 규명하였다. 향후 예비창업자에게 창업준비를 충분히 하여 실패를 줄이고 정부지원제도의 지원체계가 복잡하지 않은 효율적인 제도가 되길 시사점으로 제시하였다. 실증 분석의 대상은 인천지역 직장으로 고용에 불안한 비정규직과 퇴직을 앞둔 남녀로 조사 258개 데이터로 사용 하였으며 창업을 하고 싶지만 자신감이 부족하고 실패에 대한 불안감으로 시작을 못하였다는 점으로 미루어보아 의미 있는 조사 분석이였다. 측정도구의 신뢰도 타당성을 검증하기 위하여 요인분석과 신뢰도 분석을 실시 카이저 (Kaiser Rule) 규칙이 있는 베리맥스(Varimax)직각회전을 이용한 주성분 요인분석을 사용하였다. 가설검증 결과 예비창업자의 심리적 특성, 창업준비 특성이 창업의도에 영향을 미치는 것으로 나타났으며 창업교육 조절효과 분석 결과는 창업준비 기간과 창업의도 간에 조절효과가 나타났다. 개인적 특성에 따른 창업의도는 창업준비 특성에서 차이가 보여 졌다. 본 연구는 예비창업자로서 창업의도에 창업자로서 특성을 갖추어 성공적인 창업을 준비하고 정부지원제도에 필요한 자료로 제시하고자 한다.

Since 2009, a new method of computing the percentage of victories is being used in the regular league of the Korean professional baseball. This method produced enormous results from the first year of application, and also had an effect on the team standings in 2010. In this paper, we have examined the effects this method had on the Korean professional baseball in 2009 and 2010. We also have discussed what the Korea Baseball Organization need to complement in using this method and suggested complementary measures.

In this paper a novel power converter for some notches generation in the point of common coupling is described. The magnitude, width, polarity, and position of the notches generated by the proposed scheme can be varied arbitrary with simple control. The scheme has good features of simple structure, high reliability, low cost, high efficiency, and the capability of arbitrary several notches generation. The converter can be used for the test of custom power devices such as UPS, DVR, active power filter, etc. The circuit operation is described and the usefulness of the scheme is verified through simulations.

We propose a new algorithm for reconstructing curves with self-intersections from sample points. In general, the result of curve reconstruction depends on how to select and order the representative points to resemble the shape of sample points. Most of the previous point ordering approaches utilize the Euclidean distance to compute the proximity of sample points without directional information, so they can not solve the non-simple curve reconstruction problem. In this paper, we develop a new distance estimating the adjacency between sample points, which is derived from the standard normal distribution of Brownian motion. Experimental results show that this approach is very effective to non-simple curve reconstruction.
