The regional infrastructure industries of Gwangyang City, the subject of this study, are Gwangyang Port and Gwangyang Steel Mill. Therefore, it is necessary to analyze the regional economic ripple effects of the port logistics industry in Gwangyang City. In this study, a multi-stage approach using the RW and the LQ methodology using the national input-output tables in 2015 and 2019 is used to prepare the regional interindustry analysis chart in Gwangyang City, and an exogenous demand induction model that reclassified the port logistics industry was applied. Through this, the purpose of this study was to provide policy implications by figuring out the regional economic ripple effects of the port logistics industry quantitatively in Gwangyang City. As a result of the analysis, the industries with high production inducement effect and forward/backward linkage effect of the port logistics industry in Gwangyang City were analyzed as manufacturing, transportation, land and air logistics sectors. And the industries in which the added value inducement effect and the employment inducement effect were analyzed as an industry related to the service industry. Therefore, it is necessary to prepare support measures to foster the port logistics industry as a way to promote these industries and revitalize the local economy of Gwangyang City. To this end, it is desirable to improve policies and systems for the vitalization of the Gwangyang port maritime cluster and provide various policy support for the port logistics industry in Gwangyang City. This study is meaningful in suggesting policy implications for the regional economy of Gwangyang City based on the results of exogenous analysis of the port logistics industry in small and medium-sized cities. However, It seems that further studies related to this will be needed in the future.

Surgery first approach in orthognathic surgery is to proceed the orthognathic surgery without preoperative orthodontic treatment. This approach has many advantages, which include a shorter total treatment period, a high level of patient satisfaction due to immediate post-surgical facial improvement, easy postoperative orthodontic treatment due to early normalization of skeletal muscle, and the rapid tooth movement reflecting the regional accelerated phenomenon. However instability due to transient occlusal interference after surgery make worse of long-term skeletal stability. Especially increasing of vertical occlusion caused by interference of interbicupid and molar happen postsurgical skeletal change. Until now, there is no common consensus about treatment protocol of surgery first approach in orthognathic surgery. The purpose of this paper is to introduce our treatment protocol of the surgery first approach and to evaluate indication and limitation with case analysis.

무선 네트워크를 통해 인터넷에 접속하려는 이동노드 수가 늘어남에 따라 다수의 이동노드에게 무선 서비스를 제공해야하는 HA(Hone Agent)와 FA(Foreign Agent)에서의 부하도 함께 증가하고 있다. 특히 지역적 등록(Regional Registration)에서와 같이 투선 네트워크 도메인의 최상위 FA가 현재 도메인에 로밍한 모든 이동노드의 COA로 동작함으로 인해 발생하는 부하는 최상위 FA에서 혼잡 및 지연의 원인이 된다. 이에 본 논문에서는 최상위 FA에서 발생말 수 있는 부하를 하위 FA에게 분산하기 위하여 두 가지 접근방법인 Passive Approach와 Active Approach를 제안한다 Passive Approach는 부모 FA가 부하 분산 시점을 결정하여 자식 FA에게 분산해주는 기법이고 Active Approach는 임의의 FA가 스스로 분산 시점을 결정하여 상위 FA에서 발생할 수 있는 부하를 완화시켜주는 기법이다. 시뮬레이션을 통해 Active Approach의 한 형태를 띠고 있는 기존 연구인 LNSP 기법과 성능을 비교하여 가장 효율적인 부하 분산 방법을 제시한다.

This study applies grounded theory to develop an emic substantive theory of regional integration in Greater East Asia. The role of norms and policies is explored through discursive content analysis of a wide theoretical sample of official elite policy statements dealing with regionalism and related policy areas. A resulting model of regional integration titled "Harmony through Holistic Engagement" is then discussed in relation to the etic consensus on the phenomenon. The study concludes that the etic consensus on the nature of regional integration in Greater East Asia greatly differs from the results of an emic approach and thus reflects a normative consensus rather than a descriptive reality.

In estimating the azimuth of regional earthquakes with single -station three - component data, in some cases the result is dependent on the selection of waveforms, making the measurement subjective and inconvenient in automatic detection. In this paper an alternative approach is proposed in which the azimuth is measured from quite a long wave train by time - direction stacking technique. Test with digital waveform data from Korean seimic stations shows that the simple algorithm seems to be able to give a better estima- tion of azimuth of earthquakes at regional distances.

The complex regional pain syndrome(CRPS) is a painful and disabling disorder that can affect one or more extremities. Unfortunately, knowledge concerning its natural history and mechanism remains very limited. Many current rationales in treatment of CRPS are mainly dependent on efficacy originate in other common conditions of neuropathic pain. This article introduces various treatments for CRPS, but few studies of high methodological quality have been carried out into the effects of those treatments. I think early recognition and a multidisciplinary approach to management seems important in obtaining a good outcome.

In 1996, China, Japan and the ROK all became the party to the 1982 United Nations Convention on the Law of the Sea (UNCLOS). Since then, the UNCLOS has been a fundamental basis for the resolution and management of maritime disputes amongst them. However, there still remain acrimonious disputes in the region. Resources nationalism and the revival of geopolitics aggravates the disputes particularly on sovereignty over disputed islands, maritime delimitation and the legal nature of military activities in other States' Exclusive Economic Zones. Under the circumstances, why have the demands for the conclusion of a regional agreement been raised in this region? A desirable regional agreement regarding ocean affairs should be compatible with the rights and obligations under the UNCLOS, a universal norm regarding ocean affairs. This paper will propose a desirable regional agreement by adopting an incremental approach.

In this paper, we propose an approach that efficiently builds regional hazardous weather prediction models based on past weather data. Doing so requires finding the proper weather attributes that strongly affect hazardous weather for each region, and that requires a large number of experiments to build and test models with different attribute combinations for each kind of hazardous weather in each region. Using our proposed method, we reduce the number of experiments needed to find the correct weather attributes. Compared to the traditional method, our method decreases the number of experiments by about 45%, and the average prediction accuracy for all hazardous weather conditions and regions is 79.61%, which can help forecasters predict hazardous weather. The Korea Meteorological Administration currently uses the prediction models given in this paper.

The framework of "blue ocean strategy (Kim and Mauborgne, 2005)" applies to not only business firm level but also region or regional industry level. The paper suggests an approach of survey-based blue ocean strategy formulation. The result from survey on customer group and non-customer group gives information on positions of value curves for regions on strategy canvas and hints on how to reposition the focal region's value curve for both increases in value for customers and decreases in cost for local government, i.e., value innovation. In the context of rafting industry in Korea, this study shows the process how blue ocean strategy can be formulated with results from the survey on customers and business people in rafting industry. Relative positions of value curves on strategy canvas and importance scores for strategy elements provides the local government in region A with implications on which elements to raise or to reduce to create "blue ocean" in rafting industry under fierce inter-region competition.

A GIS-based regional risk analysis program to interactively study the vulnerability of bridges in a regional highway network is described. The analysis utilizes three major components. The use of a GIS system as the integrating environment to display geographic data, to handle inquiries and to display the results of a query. A risk model for bridges which can predict the level of damage due to a particular intensity of ground motion at a bridge site. A ground motion attenuation model to predict the intensity of ground motion at a particular bridge. The interactive components are supported by data files which encode characteristics such as potential earthquake sources and magnitudes, and characteristics of the bridges which are important for damage and failure analysis.
