본 연구의 목적은 DEA를 사용하여 지방해양수산청의 생산효율성과 경쟁력을 측정하고자 하는 것이다. DEA를 사용한 분석 결과에 따라 비효율적 지방해양수산청은 항만행정과 공공기관의 생산 효율성을 강화하기 위하여 수범 지방해양수산청을 벤치마킹할 것이 권고된다. 생산효율성에 관한 자료는 모든 활용영역에서 정책 입안자에게 방법론을 제공하고 다양한 체제에서 운용할 수 있는 기초가 될 것이다.

한국특산종인 Colitis rotundicuudutu의 지리적 변이를 전국 5개 집단 132개체를 대상으로 조사하였다. 4개 집단의 계측형질로 본 다변량분석 결괴 산청집단은 타 집단과 형태적 차이가 있었다 전기영동으로 조사된 5개 집단의 평균 유전적 변이 정도는 A=1.48, P=37. IpA, HD=0. 139, 및 H6=0. 124로 변이 정도가 타 어류에 비하여 비교적 높았다. 5개 집단의 평균 유전적 근인치(S)는 0.83으로 낮았으나 산청집단을 제외한 4개 집단의 근연치는 0. 91로 매우 가까웠다. 반면 산청집단은 나머지 집단과 형태적으로나 유전적으로 유의한 차이가 나타나는 것으로 보아 산청집단의 별종 가능성이 매우 높음을 시사한다. 앞으로 보다 면밀한 연구로 산청집단의 별종 여부를 명백히 구명하여야 할 것이다.

Acer tegmentosum Maxim (AT) is a species of the maple genus, which is native to North-Eastern China and Korea. Traditionally, AT has been already used for pain relief in Korea. On the other hand, its antidepressant-like activity and related molecular mechanisms is not completely understood. Using the Forced Swimming Test (FST), the effects of a subacute treatment with AT(100, 200, and 400 mg/kg, p.o.) on the immobility and FST-induced changes to the immune parameters, cortisol, ACTH, and cytokine, in rats were investigated. The tendency of immobility showed a dose-dependent decrease in FST. The levels of cortisol, IL-6 and $IL-1{\beta}$ in the peripheral blood were increased significantly after FST exposure. Overall, these results suggest that AT treatment can decrease the immobility time and the release of pro-inflammatory cytokines in the FST, suggesting that the anti-inflammatory effects of AT might be involved in the antidepressant-like effect.

지방해양수산청은 항로표지 관리운영시스템을 운영하고 있다. 이 시스템을 활용하면 항로표지에 설치된 장비 상태를 현장에 직접 가지 않아도 알 수 있어서 관리가 편리하고 장비고장을 미리 예방할 수 있다. 이 연구에서는 관리운영시스템을 적극 활용하여 항로표지 점검 정비를 실시하는 등 항로표지 현장 디지털화를 목표로 하고 있다.

Sr isotopic compositions are determined from the syenite of Sancheong area, yielding age of $211{\pm}23(2\sigma)$ Ma and $^{87}Sr/^{86}Sr$ initial ratio of $0.70598{\pm}0.00060$. Such result confirms that Sancheong syenite was emplaced during the Mesozoic around the Triassic-Jurassic boundary. Rather low initial $^{87}Sr/^{86}Sr$ ratio suggests insignificant influence of old crustal materials. There are strong contrast in rock types of plutonic associations between Sancheong-Macheon area and adjacent Hamyang-Geochang area to the north, i.e. syenite-diorite-gabbro and granite-granodiorite respectively. $^{87}Sr/^{86}Sr$ initial ratios also show distinction between these areas. Such differences suggest regional contrast in tectonic environments between them.

The purpose of the present study is to explore the significance of the Commentaries on Pavilions (樓亭記) from the Sancheong-gun area. To achieve this purpose, the study analyzes the works handed down in Sancheong-eup, Chahwang-myeon, Obu-myeon, and Geumseo-myeon, focusing on the two characteristic themes: the discipline and enlightenment of heart and mind (in Chapter 2) and the succession of integrity and the tradition of ancestor worship (in Chapter 3). The first characteristic theme "the discipline and enlightenment of heart and mind" is explicated in Chapter 2 by reviewing the Commentary on Hwanajeong Pavilion (Hwanajeonggi) written for the namesake building located in Sancheong-ri, Sancheong-eup, and the Commentary on Gyeongjeonjae Pavilion (Gyeongjeonjaegi) in Maechon-ri, Geumseo-myeon. The second theme "the succession of integrity and the tradition of ancestor worship" is examined in Chapter 3 based on the Commentary on Sulgojeongsa Pavilion (Sulgojeongsagi) from Jangwi-ri, Chahwang-myeon, and the Commentary on Maeranjeong Pavilion (Maeranjeonggi) from Yangchon-ri, Obu-myeon.

The study area is located in the western part of the Precambrian stock type of Sancheong anorthosite complex, the Jirisan province of the Yeongnam massif, in the southern part of the Korean Peninsula. We perform a detailed field geological investigation on the Sancheong anorthosite complex, and report the characteristics of lithofacies, occurrences, foliations, and research formation process and its mechanism of the Sancheong anorthosite complex. The Sancheong anorthosite complex is classified into massive and foliation types of Sancheong anorthosite (SA), Fe-Ti ore body (FTO), and mafic granulite (MG). Foliations are developed in the Sancheong anorthosite complex except the massif type of SA. The foliation type of SA, FTO, MG foliations are magmatic foliations which were formed in a not fully congealed state of SA from a result of the flow of FTO and MG melts and the kinematic interaction of SA blocks, and were continuously produced in the comagmatic differentiation. The Sancheong anorthosite complex is formed as the following sequence: the massive type of SA (a primary fractional crystallization of parental magmas under high pressure)${\rightarrow}$ the foliation type of SA [a secondary fractional crystallization of the plagioclase-rich crystal mushes (anorthositic magmas) primarily differentiated from parental magmas under low pressure]${\rightarrow}$the FTO (an injection by filter pressing of the residual mafic magmas in the last differentiation stage of anorthositic magmas into the not fully congealed SA)${\rightarrow}$the MG (a solidification of the finally residual mafic magmas). It indicates that the massive and foliation types of SA, the FTO, and the MG were not formed from the intrusion and differentiation of magmas which were different from each other in genesis and age but from the multiple fractionation and polybaric crystallization of the coeval and cogenetic magma.
