  • We studied the management policy for Haliotis diversicolor fisheries in the coastal area of Sungsanpo using Yield-per-recruit model from 2004 to 2006. The age at first capture($t_c$) and fishing mortality(F) annually estimated during the study period decreased and increased, respectively. The maximum yield-per-recruit in 2004 was increased by increasing $t_c$ from the 2.012 year of current $t_c$ to 2.7 year or increasing F from the 0.574/year of current F to 0.800/year, and that in 2005 was increased by increasing $t_c$ from the 1.946 year of current $t_c$ to 2.5 year or increasing F from the 0.578/year of current F to 0.880/year. In 2006, the maximum yield-per-recruit was increased by increasing $t_c$ from the 1.926year of current $t_c$ to 3.1 year or decreasing F from the 1.088/year of current F to 0.810/year. Further, although the current F in 2004 and 2005 was lower than the estimated $F_{MAX}$, that in 2006 was higher than the estimated $F_{MAX}$. These results indicate that the likelihood of growth overfishing with increasing catch of smaller H. diversicolor in 2006 was greater than in 2004 and 2005. As action that could prevent growth overfishing in fisheries management of H. diversicolor, increasing for the current $t_c$ could be a more appropriate policy because the artificial decrease of the number of woman divers related F is actually difficult.

  • 광양지역에 자주 발생하는 해풍에 의한 대기오염물질의 농도분포 특성을 알아보기 위해, 2003년부터 2005년까지 3년간의 기상자료와 대기질 관측자료를 분석하였다. 해풍이 발생한 날은 총 231일 이었으며, 해풍이 발생한 날의 $SO_2$$O_3$의 농도는 비해풍일 경우보다 높게 나타나고 있어 광양지역의 대기질의 분포에 해풍의 영향이 중요한 인자임을 알 수 있다.

  • 2004년이후, 외국 업체들의 재고 광섬유 광케이블은 기본적으로 매진되었다. 동시에 중국 업체들고 신속히 자본통합을 진행하였으며 초고속 인터넷과 지역 네트워크 시장의 발전과 함께 전체 시장이 회복세를 보였다. 광섬유 광케이블의 시장평균가격은 3년이래 처음으로 안정적인 상태로 들어섰다. 현재 중국 국내에서 이미 생산에 들어선 광섬유 광케이블 생산업체들의 연간 생산능력은 3,000만 킬로미터 이상으로 수입을 고려하지 않은 상황에서 생산량은 이미 실수요의 2배 이상이다. 시장경쟁이 여전히 치열하고 국내 업체들의 생존압력은 비교적 크다.

  • The population and employment of Cheongju have increased rapidly since the 1970s. This study examines the industrial employment change of Cheongju City and performs a shift-share analysis for the employment growth. The data used in this study are mainly from the 1985, 2000 and 2005 Census of Population and Housing. This study first explained the population change and industrial structure of Cheongju, then reviewed the development of shift-share models. Location quotients and specialization coefficients resulted from this study revealed the diversifying tendency in the urban industrial structure. Shift-share analysis employing the modified Arcelus model elucidated the favorable industrial mix and the competitiveness of industrial sectors. As a whole, Cheongju has advantageous industrial structure in comparison with that of the nation. All sectors of Cheongju except several services sectors grew faster than those of the nation and showed positive competitive effects. It is suggested to utilize more disaggregated industrial data in more fractured subperiod in order to pinpoint the competitive industries.

  • Stink bug species and host plants occurred in fallow lands for rice product regulation were studied in Honam area from 2004 to 2005. A total of 26 bug species in 8 families were surveyed in the fallow lands. Population density of Cletus punctiger adult reached its peak in July and was higher in fallow lands close to mountain area in Muan. Population density of stink bug species occurred in plain area of Wanju were significantly low in 2004 and population density of C. punctiger adult reached its peak in July and August in fallow lands in 2005. Five species of stink bug including C. punctiger immigrated from fallow lands to rice fields in August, and three other species including Cletus schmidti in September. Eight stink bug species which were observed to feed on weeds in fallow lands were C. punctiger, C. schmidti, Eurydema gebleri, Pachygrontha antennata, Trigonotylus caelestialium, Aelia fieberi, Eysarcoris aeneus, and Nezara antennata.

  • Purpose: This study aimed to investigate the changes in the occurrence of rotavirus gastroenteritis (RGE) after the introduction of rotavirus vaccine and estimate rotavirus vaccine effectiveness in hospitalized children. Methods: We compared the retrospective data of 671 patients with acute gastroenteritis (AGE) admitted to the Department of Pediatrics, Hanyang University Seoul Hospital from January 1, 2014, to December 31, 2015, with retrospective data of 1,243 patients admitted to the same institution with AGE from January 1, 2004, to December 31, 2005. The vaccine effectiveness was estimated using a case-positive control test-negative study. Results: The proportion of RGE in AGE was significantly lower in 2014 to 2015 (9.0%, 48/531) than in 2004 to 2005 (22.7%, 282/1,243) (P<0.001). In particular, there was a significant decrease in the 6- to 11-, 12- to 23-, and 24- to 35-month-old groups (P<0.001), whose rotavirus vaccination rates were higher than the remaining age groups. The monthly distribution of patients with RGE in 2004 to 2005 was higher from November to May, peaked in January, followed by December and February. In 2014 to 2015, the monthly distribution of patients with RGE slightly peaked in January. In 2014 to 2015 study, the complete rotavirus vaccination rate was 66.0% (332/503) and incomplete vaccination rate was 6.2% (31/503). Presumed rotavirus vaccine effectiveness was 83.3% (95% confidence interval [CI], 60.5% to 92.9%) in the complete vaccination group and 27.4% (95% CI, -163.7% to 80.0%) in the incomplete group. Conclusions: The proportion of RGE in AGE has markedly decreased since the introduction of rotavirus vaccines, and improving vaccination coverage will further reduce the burden of RGE in Korea.

  • In Korea, currently 10 local governments have completed the construction of the 3D Land Geospatial Information, since the pilot project started in 2004 and many other local governments are additionally constructing the 3D Land Geospatial Information. Technical Guidance for the 3D Land Geospatial Information has made out the construction methodology and concept of the ordinances in 2006 by the basis of the research results of the pilot project for the 3D Geospatial Information construction in 2005. But the result that applied the existing 3D Land Geospatial Information of the local governments, many problems rearing up on the methods and expression accuracy of the 3D Land Geospatial Information. This research analyzed and derived problems of established guideline for the zero-defects construction of the 3D Land Geospatial Information and it is aim at the present standardized criterion of the reestablished and method of the 3D Geospatial Information construction items. Improvement scheme of the 3D Land Geospatial Information is considered to be contribute to the standardized good quality of 3D Land Geospatial Information construction and its application.
