Software maintainers try to comprehend software source code by intensively using source code identifiers. Thus, use of inconsistent identifiers throughout entire source code causes to increase cost of software maintenance. Although participants can adopt peer reviews to handle this problem, it might be impossible to go through entire source code if the volume of code is huge. This paper introduces an approach to automatically detecting inconsistent identifiers of Java source code. This approach consists of tokenizing and POS tagging all identifiers in the source code, classifying syntactic and semantic similar terms, and finally detecting inconsistent identifiers by applying proposed rules. In addition, we have developed tool support, named CodeAmigo, to support the proposed approach. We applied it to two popular Java based open source projects in order to show feasibility of the approach by computing precision.

This study began with the problem of establishing the identity of the region through tourism storytelling and the need for economic and cultural recovery. Thus, we analyze the attributes of tourist-aware tourism storytelling, authenticity through experience in tourist attractions, and structural and causal relationships between behaviors. Studies have shown that the attributes of tourism storytelling's sensibility, educationality, ease of understanding, interest and theme have a significant impact on tourists' authenticity experiences. And it was confirmed that the authenticity experience of tourists has a positive impact on tourists' intentions of visiting and oral intentions. This study is of high academic significance in that it applied the attributes of storytelling, which had been studied in the existing linguistics and humanities, to Namwon, a representative cultural tourist destination in Korea. In addition, in order for Namwon to grow into a global cultural tourist destination, it is necessary to develop tourism storytelling using unique storytelling attributes and local resources, and furthermore, it is meaningful to suggest that various contents and services should be developed.

OECD등 국제기구와 현재 국회에 계류 중인 물 관리기본법 제정(안)등에서 물 이용자에 대한 수익자 부담 원칙을 요구하고 있어, 농업용수의 대부분을 관리하고 있는 한국농어촌공사 관리지역의 농업용수 이용료(구 조합비) 면제에 대한 문제점이 제기되고 일부 전문가들 사이에서도 농업용수 이용료 부과의 필요성이 지속적으로 제기되고 있는 실정이다. 이러한 시점에서 과거 농업용수 이용료(구 조합비) 부과 및 면제의 역사를 살펴보고, 농업용수 및 농업 농촌의 특성을 고려한 농업용수 이용에 따른 수익자 부담원칙에 대하여 검토하였다. 농업용수 이용료는 1908년 수리조합이 시작된 이후 1999년까지 조합비 형태로 부과하다가 2000년 농업용 수관련 3개 기관이 공사로 통합하면서 면제가 되었고, 지난 10년 동안 외부(OECD 등)의 요구뿐만 아니라 내부적으로도 농업용수관리 비용증가로 인한 이용료 부과가 필요하다는 주장이 제기되었다. 한편 이용료 부과시 농업인 경제적 부담증가, 농업용수관리 정책의 혼선, 농업인 반발로 인한 사회문제화, 이용료 징수의 실효성 및 실익성에 대한 문제가 발생될 수 있다. 따라서 농업용수이용에 대하여 단순히 수익자 부담원칙 준수를 요구만 할 것이 아니라 면제에 대한 역사적, 사회경제적인 배경과 농업 농촌의 특성을 이해하고 국내외적으로 대두되는 수익자 부담원칙에 대하여 어떻게 합리적인 방법과 사회적인 합의를 이끌어 낼 것인가 장기적인 연구와 검토가 필요하다. 또한 비용부담측면만이 아니라 농업인의 물 관리 참여(PIM, Participatory Irrigation Management)등을 통한 수익자부담 원칙 달성 및 비용절감을 유도할 수 있는 제 3의 방안을 찾아야 한다.

Purpose: The purpose of this study was to assess characterize overseas company's Cellulose acetate glasses frame sheets (overseas company's CA sheet) Also, the optimum content of plasticizer and melt extrusion condition of industrial CA resin were established for appropriate glasses frame. Methods: Overseas company's Cellulose acetate glasses frame sheets (overseas company's CA sheet) were characterized by $^1H$-NMR, GPC, and TGA. Also, the optimum content of plasticizer and melt extrusion condition of industrial CA resin were established. Results: The plasticizer of overseas company's CA sheet measured by $^1H$-NMR was diethyl phthalate, and its content was measured 30 wt% by TGA. Also, industrial CA resin showed enough melting behavior in the range of 190~200$^{\circ}C$. Compared to overseas company's CA sheet's tensile strength value of 2.2~2.8 kgf/$mm^2$, industrial CA resin exhibited sufficient tensile strength value of 2.3 kgf/$mm^2$ for glasses frame. Conclusions: Industrial CA resin with 30 wt% plasticizer content would be a promising material for glasses frame prepared by melt extrusion to replace China CA sheet.

The main purpose of this study is to suggest the spatial statistical approach suitable for the delimitation of Busan CBD. For this purpose, Getis-Ord $G_i^*$ and both of IDW (Inverse Distance Weight) and FDB(Fixed Distance Band) were applied to delimit the CBD boundary. And then, the results of the CBD boundary were compared and verified with the methodologies of the previous studies. The result of IDW accorded with the previous study relating to the delimitation of the boundary of CBD, and the result of FDB was reflecting the characteristics of the mixed-use residential of a transition zone. As a result of the land use quotient, the mixed land use of residential and commercial was highly specialized in the boundary of FDB. These results will be able to support the understanding of urban spatial structure and the effective CBD management.

This paper introduces a simulator to assess the impacts of the wind and the airframe vibration on the performance of the Active Electronically Scanned Array (AESA) radar mounted in an aircraft. The AESA radar is mounted on the nose cone of an aircraft, and vibration occurs due to the drag force. This vibration affects the behavior of the AESA radar and can cause phase errors in signal. The simulator adopts the geometric model for nose cone, the mathematical models on the rigid-body dynamics of the aircraft, the average/turbulent winds, and the mode/ambient vibrations to compute the position and the attitude of the radar accurately. Numerical studies reflecting a set of test scenarios were conducted to demonstrate the effectiveness of the developed simulator.

This paper studied the effects of service quality and system quality that affect customer's satisfaction and continued usage intention regarding mobile network conditions. The hypotheses and research models were completed using research factors of service quality(reactivity, empathy) and system quality(connectivity, ease of use, channel-mobility) borrowed from previous studies on DMB and IPTV. The hypotheses and research models were verified through experiments and surveys. The key finding showed that customer's expectation on service quality and system quality under fast network(Wifi) was higher than that of under slow network(3G). Furthermore, it showed that users react more sensitive to service quality than to system quality such as network speed. Based on the results, this study has the implication for expanding the understanding of the factors used in previous DMB and IPTV studies by applying them in N-screen domain.
