The purpose of this study is to analyze the landslide susceptibility, containing the process, which reveals spatial relationships between landslides and geospatial data sets, which occurred in Janghung area in 1998. Landslide locations were detected from remotely sensed image and field survey and topography, soil, forest, and land use data sets were constructed as a spatial database in GIS. As the landslide occurrence factors, slope, aspect, curvature and type of topography, texture, material, drainage and effective thickness of soil, type, age, diameter and density of wood and land use were used. To extract the relationship between landslides and geospatial database, likelihood ratio was calculated and compared with the result of Yongin area. Also, the landslide susceptibility index was calculated by summation of the likelihood ratio and the landslide susceptibility map was generated using the index. As a result, it is expected that spatial relationships between landslides and geospatial database is helpful to explain the characteristics of lilndslide and the landslide susceptibility map is used to reduce associated hazards, and to plan land use and construction.

We examined the developmental characteristics of dream, daydream, and hope of elementary school students in their 1st, 3rd, and 5th grades, and studied the correlation between three variables. We summarized the results of this study as follows. 1) The contents of dream developed with the cognitive development and socialization process. In detail, appearance of animals, family members, and known persons gradually decreased, and appearance of self, same-sex peers, and strangers gradually increased. These results are comparable with the previous studies of dream. 2) Daydream, hope, and current state also developed with age. In detail, frequency of daydream increased, and the contents of daydream and hope changed toward more self-centered and more realistic. The changes of current state are thought to reflect the specific situation of Korea. 3) There are some correlation among dream, daydream, and hope. Especially happy mood and fearful mood had positive correlation with the relevant contents of dream, daydream, and hope. Also the contents of dream showed positive correlation with the same contents of daydream. This study is the first trial which investigate the developmental characteristics of dream, daydream, and hope of normal children in Korea. We verified that dream and daydream are on the continuous line of ‘reality-imitation-play-daydream-dream’ Finally, considering the facts that dream developed with age；responded to meaningful emotional experiences；and had the correlation with daydream, hope, and current state, the results of this study support the psychological meaning of dream.

GIS의 국가적 틀을 이루는 공급주체에는 중앙정부 이외에도 지방자치정부가 있다. 현실적으로 지방자치정부는 행정 일선에 위치하고 있으며 각 지역의 특수성을 고려하여 지역 주민들의 수요를 충족시키고 행정서비스의 질을 향상시키기 위하여 GIS를 도입할 수 있는 대표적인 기관들이다. 학계의 전문가들은 공공 부문 업무의 80%가 지리적 연관성을 갖는 것으로 보고 있기 때문에 향후 GIS가 정부의 서비스 제공과 관리자들의 의사결정에 필수적인 요소로 자리잡을 것으로 예측된다. 본 연구의 목적은 국내 기초지방자치정부가 정부의 행정효율을 향상시키기 위하여 그리고 국민을 위한 서비스의 질을 높이기 위하여 GIS를 얼마나 도입하여 활용하고 있는지를 알아보고자 했다. 또한 이러한 조사분석을 통하여 얻은 결과들을 정리하여 국가적으로 GIS의 활용을 촉진할 수 있는 방안들을 담고자 하였다.

In this paper, an image-based luminance measurement system(LMS) is proposed to measure the luminance of outdoor signboards. We design the LMS that can improve disadvantages of efficiency of the point-luminance meter and portability of face-luminance meter using the image of DSLR camera and print out the luminance value by using the proposed luminance analysis algorithm in real time. Outdoor signboards have various size and shape, and are also installed on the various place. Luminance of the signboard is influenced by measurement location, angle, color, etc. Therefore, we measure the change of luminance value in accordance with measurement location for accurate luminance measurement and then consider the luminance value according to the measurement distance. We obtain a numerical relation between luminance value and measurement location. The proposed LMS is verified through comparative experiment with point-luminance meter.

This study analyzes the economic impact of the shipping and port logistics industry in Gwangyang Bay Area on the regional economy. For this purpose, the study constructs an input-output table of 29 sectors for 2010 in the area. The main findings are as follows. In terms of production, value added, and share of employment, the regional shipping and port logistics industry accounts for approximately 10.8 percent, 6.0 percent, and 2.9 percent of the national shipping and port logistics industry, respectively. Moreover, the economic impact of the industry on the regional economy is estimated to be an increase in terms of production of about 6 trillion Korean won), to be an increase in value added of about 2.5 million Korean won, and an increase of about 16,000 in employment. Furthermore, the industry is found to have strong inter-industry linkages with the main manufacturing as well as the main producer service industries.

The purpose of this study is to determine how the Korean diphthong /jo/ shows phonetic variation in various linguistic environments. The pronunciation of /jo/ is discussed, focusing on the relationship between phonetic variation and the distribution range of vowels. The location in a word (monosyllable, word-initial, word-medial, word-final) and word class (content word, function word) were analyzed using the speech of 10 female speakers of the Seoul Corpus. As a result of determining the frequency of appearance of /jo/ in each environment, the pronunciation type and word class were affected by the location in a word. Frequent phonetic reduction was observed in the function word /jo/ in the acoustic analysis. The word class did not change the average phonetic values of /jo/, but changed the distribution of individual tokens. These results indicate that the linguistic environment affects the phonetic distribution of vowels.

The importance of the hyoid bone lies in its unique anatomic relationships. It has no bony articulations but provides attachment for muscles, ligaments, and fascia of the pharynx, mandible, and cranium. Various studies have documented a variability of hyoid bone position in relation to changed mandibular position or head posture. The aim of this study is to investigate the hyoid bone position and inclination on cephalometric radiographs of three groups of patients exhibiting Class I, II, and III malocclusions. The conclusions obtained from this study can be summarized as follows ; 1. Class III malocclusion patients show a more anterior position of the hyoid bone and also less steep inclination of the hyoid bone. 2. The anteroposterior position of the hyoid bone relative to the cervical vertebra and mandible was very constant. 3. The hyoid bone represented the anterior bony boundary of the pharynx at a lower level than PNS.

가금산업은 국민소득 증가와 식생활의 서구화로 생산액과 소비량이 증가하여 우리 농업에서 매우 중요한 위치를 차지하고 있다. 그러나 세계 각지에서 나타난 고병원성 조류인플루엔자로 인하여 많은 경제적 피해가 발생하고 있으며, 질병의 인체감염으로 인간의 소중한 생명도 위협을 받고 있다. 우리나라의 경우도 예외가 아니어서 그동안 모두 3차례에 걸쳐 고병원성 조류인플루엔자가 발생하여 많은 피해를 입었다. 고병원성 조류인플루엔자의 발생으로 인한 경제적 피해는 가금생산농가에만 국한되는 것이 아니다. 질병 발생으로 인한 경제적 피해는 생산농가와 직간접적으로 연관된 사료업체, 부화업체, 가공업체, 유통업체, 외식업체, 및 기타 관련 산업에서 골고루 발생하며, 손실보전을 위한 정부의 재정지출 증가로도 이어진다. 이번 연구에서는 고병원성 조류인플루엔자(HPAI) 발생이 미치는 경제적 영향을 계측하고 이와 관련하여 현행 질병 방역체계의 개선 방향을 도출하였다. 근래 들어 고병원성 조류인플루엔자의 연중 발생 가능성이 우려되기 때문에 질병예방과 확산방지를 위한 방역체계의 검토에서 개선 방안에 이르기까지 포괄적으로 다루었다.

This study was performed to investigate the skeletal factors related to open lock of the temporomandibular joint(TMJ). We compared the skeletal measurements on the cephalogram and transcranial radiograph among 3 groups, open lock group consisting of consecutively filed 50 patients with at least one open lock episode within recent 1 year, temporomandibular disorder(TMD) group of 50 TMD patients without open lock diagnosed by Research Diagnostic Criteria for TMD (RDC/TMD) Axis I, and normal group of 50 patients without TMD or open lock. The patients of TMD and normal group were randomly selected in an age-and-gender-matched way with ones of open lock group. Open lock group showed smaller saddle angle than normal group on cephalograms and steeper inclination of the articular eminence than TMD and normal groups on transcranial radiographs. These results imply that the patients with the joint located more anterior and the articular eminence with steeper inclination might be riskier to TMJ open lock.
