This exploratory study analyses the factors, sources and effects of the regional competitive advantage of Jeju Island in Korea in global competition era. The competitive advantage of Jeju Province is analysed with the triple diamond model based on Porter's model for the competitive advantage of nations. The competitive advantage factors of Jeju Province are measured through the competitive advantage of the hospitality industry, which is one of the major industries of Jeju Island. These factors include outstanding natural landscape, domestic hospitality industry workforce, social overhead capital, massive domestic and international tourists, growth of related industries such as duty free shops and casinos, and coincidences such as Jeju Olle trail construction and Chinese government's international travel approval. Since these factors are based on local, domestic and international management resources, this study suggests that obtaining such resources is critical among Jeju hospitality industry in gaining the competitive advantage. Although the competitive advantage of Jeju hospitality industry is increasing, the organic connections with the regional economy are required for improvements on Jeju residents' quality of life. This study examines the factors and origins of competitive advantages on a regional level instead of a national level, and further investigates how the characters and origins of these factors affect the local economy. The results suggest that the triple diamond model is suitable for evaluating the regional competitive advantages.

Abundant spinel lherzolite xenoliths showing distinctively different textural types such as protogranular, porphyroclastic, and mylonitic texture are trapped in the basaltic rocks from southeastern part of Jeju Island. These xenoliths show the textural spectrum from coarse-grained protogranular through porphyroclastic with bimodal grain size to fine-grained and foliated mylonitic texture. They tend to decrease in grain sizes and show more linear grain boundaries and more frequent triple junctions from protogranular through porphyroclastic to mylonitic. Spinel has different occurrence mode according the textural type. Spinel is always associated with orthopyroxene in protogranular texture, whereas it is scattered and independent of orthopyroxene in mylonitic texture. Additionally, porphyroblast from porphyroclastic and mylonitic textures has internal deformation features such as kink band, undulatory extinction and curved lamella, whereas neoblast is strain-free. These textural features indicate increasing degree of static/dynamic recrystallization from protogranular through porphyroclastic to mylonitic texture. The mg#[$=100{\times}Mg/(Mg+Fe_t)$] of olivine, orthopyroxene and clinopyroxene is relatively constant (ol: 88-91; opx: 89-92; cpx: 89-92) regardless of textural differences. The mg# of constituent minerals, NiO content (0.3~0.4 wt%) and MnO content (0.1~0.2 wt%) of olivine are similar to those of mantle xenoliths worldwide, also indicating that studied spinel lherzolite xenoliths were mantle residues having experienced 20~25% partial melting. The geochemical and textural characteristics have close relations showing that LREE and incompatible trace elements content of orthopyroxene and clinopyroxene increases from protogranular through porphyroclastic to mylonitic. These observations suggest that the studied mantle xenoliths experienced metasomatism by LREE enriched melt or fluid after partial melting, indicating a close relation between deformation and metasomatism. The metasomatism was possibly confined to narrow shear zones from where porphyroclastic and mylonitic textured xenoliths originated. These shear zones might favorably drive the percolation of LREE-enriched melts/fluids responsible for the metasomatism in the lithospheric mantle below the Jeju Island.

최근 전 세계적으로 기상이변 현상이 과거에 비해 빈번하게 발생하고 있으며, 자연재해에 의한 피해도 증가하고 있다. 한국에서 주로 발생하는 자연재해로는 호우, 태풍, 대설 등이 있고 최근 10년(2008~2017) 동안 자연재해 피해액 약 3.4조 중 대설에 의한 피해액은 약 2,200억원으로 전체 자연재해 피해액 중 약 15%를 차지하고 있다. 과거 2014년 경주 리조트에서 폭설로 인해 지붕이 붕괴되어 10명이 사망하고 100여명이 부상당하는 사건이 발생하였고, 2018년 제주도 농가지역의 시설물 및 재배작물이 수십억의 피해를 입게 되는 등 대설로 인한 큰 피해를 입는 사례들이 나타나게 되어 대설피해에 대한 관심이 높아지고 있는 추세이며 겨울철 주요 자연재해 중 하나로 인식되고 있다. 본 연구에서는 취약성 분석을 위해 PSR구조인 압력지수(Pressure), 상태지수(State), 대응지수(Response)로 인자들을 나누고 엔트로피 방법을 이용하여 전라도 지역 41개 시군구를 대상으로 가중치를 산정하였으며 이에 따른 결과 값들로 전라도 지역 41개 시군구에 대한 취약성 분석을 실시하였다. 그 결과 대설에 취약한 지역들을 순위로 도출해낼 수 있었다. 본 연구에서 도출해낸 결과를 바탕으로 하여 대설에 가장 취약한 지역들을 중심으로 대응 방안을 마련하여 대설에 대비한다면 효과적인 도움을 줄 수 있을 것으로 판단된다.

This paper examines the provisions in the current law related to impeachment and proposes the direction for legislative improvement. For this purpose, this paper first analyzed the meaning of the provisions related to the impeachment system in the present law and examined the proposed legal theory in applying it to the case. The main purpose of this review is to identify deficiencies and uncertainties in the content of the regulation of law that arise in applying the regulation of law to the cases. The following problems are presented from it.: (1) the provisions on reasons for impeachment prosecution, (2) the distinction between causes of impeachment prosecution, (3) the duty of the National Assembly to investigate the reasons for impeachment prosecution, (4) Provisions concerning the sentencing of dismiss in the impeachment decision (4) "acts of betraying the credibility of the people" as a decision on discharge, (5) provisions on a fixed number for judgment for impeachment In order to solve these problems, this paper used a comparative method to examine cases in the United States and Germany. In addition, when the legal system is heterogeneous, the constitutional ideology or values of our constitutional system are considered and the direction for the legislative improvement is suggested.
