Purpose - Alliance members have constantly revised market strategies over time by withdrawing membership from a current alliance, joining another alliance, or constructing a new alliance. From the perspective of the signaling effect, the purpose of this study is to analyze the impacts of partner volatility (new member, old member, and new group) on firm value. Design/methodology - To analyze the impact of partner volatility on firm value, companies in strategic alliances are classified into the three groups of new partner, existing partner, and new alliance, and the effects on company value are verified through an event study and the signaling effect analysis. Findings - This study proved that new partners and newly formed strategic alliances have higher expectation effects than old partner company groups, and have a more positive effect on the relevant firms' stock prices. In addition, the result of the study showed the same valid results as the alliance levels, and showed that investors' expectations were higher with new partners and new alliances than with old partners. Research Implications - A new perspective on the signaling effects of strategic alliances among shipping lines was presented in this study by grouping alliance types including new member, old member, and new group. The results provide useful insights for selecting partners and firm values of alliance announcement times. Originality/value - This study analyzed partner volatility on relevant companies' stock prices from the perspective of investors from the global shipping conference reorganization in 2017. Strategic alliances were classified into the three categories of new partner, old partner, and new alliance, and the effects on firm value were verified.

목조건축물로부터 해체된 고목재를 해당 건축물의 복원이나 새로운 건축물에 재사용하기 위해서는 열화 및 부후 부위를 제외한 건전재의 재질 및 강도성능에 대한 평가가 필요하다. 트러스 현재로 사용된 부재와 사찰에 사용된 부재에 대해 현미경으로 수종식별을 행하고 KS 기준에 따라 각종 물성 및 강도 시험을 행하여 문헌에 의한 결과와 비교 검토하였다. 잎갈나무(Korean larch)는 재질 및 강도 성능이 기존 문헌값보다 높게 나타났으며, 소나무(Korean red pine)와 가문비나무(Yezo spruce)의 경우 해체재의 강도성능이 대체적으로 낮게 나타났다. 육안에 의한 건전부위의 시험편 내의 조직적 열화는 현미경적으로도 관찰되지 않았다. 인장시험편의 중앙부 두께가 5 mm에서 3 mm로 변함에 따라 인장강도가 증가하여 시험편 치수에 대한 검토가 필요한 것으로 판단되었으며, 압축 및 휨 시험법은 현행 기준으로도 적합한 수준이었다. 고목재류에 대한 구체적인 기초 강도 성능평가를 위한 시험방법 및 철물접합부의 접합성능에 대한 차후 연구 검토가 필요한 것으로 평가되었다.

This is the basic study for being activated rural area through charged old folk's home as the rural facilities. In Korea, it was recognized legalistically from 1993, and 15 homes are operated at present by personal social worker and public-welfare service corporation. The first of 2000's, Korea will be changed aged society and a member of each family will be smaller than 3.5 persons. At that time, the many of aged korean have to live separately from their sons and daughters. And some of them will live only with their wives/husbands or alone in the charged old folk's home. Therefore, the importance and the demand of charged old folk's home will be increasing rapidly in Korea. And so we, all the rural architect have to develope it for aged person.

Introduction : In patient with ankylosing spondylitis, when bone formation progresses, spinal fusion occurs and joint motion is severely limited. We performed Medical Gi-gong and Korean medical therapies in patient with advanced ankylosing spondylitis with spinal fusion. Case : 46-year-old male with extensive spinal fusion at the cervical and lumbar spine complains of back pain, hip pain, joint stiffness, eye pain, and digestive problems. HLA-B27 (+), mSASSS is 70. Medical Gi-gong was done 311 days for 340 days. Acupuncture, cupping, and manual treatment were performed once every 5.9 days for one year. BASDAI improved from 5.3 to 4.3, BASFI from 4.3 to 3.7, and BASMI from 6.8 to 5.8. mSASSS did not change. Conclusions : Patients with advanced ankylosing spondylitis were treated with Medical Gigong and Korean medical therapies to achieve a slight improvement.

M82 is a famous starburst galaxy which is dominated by young stellar populations and ISM. Some previous studies indicated the existence of intermediate-age and old stellar population in this galaxy, but little is known about them. We present a study of old globular clusters in M82 using the Hubble Space Telescope archive data. From the cluster survey of M82 we found 650 star clusters. We divided them into disk and halo star clusters according to their position. The color-color diagrams show that all 19 halo star clusters are old globular clusters. The disk sample may include both reddened young clusters and geniune old globular clusters. We estimated their ages using spectral energy distribution fit method with six filter data covering from ultraviolet (F330W) to infrared (F160W), and found that 30 of them are older than 3 Gyr. These are considered to be disk globular clusters. Twelve of the halo globular clusters are found to be partially resolved into their member stars. The (B-V) color range of the halo globular clusters is consistent with that of the Milky Way globular clusters, but most of M82 globular clusters are bluer than (B-V)=0.7. The existence of these old globular clusters suggests that the starburst galaxy M82 has an old stellar halo that may be as old as the Milky Way halo.

In the case of a rail road bridge extension work, especially single track to double track, the foundation of new substructure which supports the extended part of superstructure could be interfered by the exist foundation of an old bridge. When these two foundations are jointed to prevent such fatal effects of the structure as unequal subsidence of soil foundations, it is important to prove the structural behaviour of the joining surfaces between new foundation and old foundation. 3-Dimensional Finite Element Analysis Method have been studied for the solutions of the structural behaviour of the foundations. In this analysis, 'Contact Element' which allows the sliding of each adjoining member is used for the joint of the boundary surface of the old and new pier foundations. Furthermore, Material Nonlinear Behaviour Analysis also supports the accuracy of the result in this study because the foundations consist of concrete main bodies and reinforced steel bars. These detailed analyses secure the verification of the structural safety of the foundations in the extension work more firmly.

Over the course of time, changes occur in family composition and members, and such changes impact housing life as well. In contrast to shared housing structures such as apartments, detached houses show a greater variety of changes to interior spaces such as family composition, rural area, natural environment, and modernization. The purpose of this study is to examine the change and factors in interior spaces in detached houses of rural area. Out of 40 houses studied in a 1995 survey, 23 showed changes when studied again in 2015, and 13 were selected for final analysis. This study indicated that at the time of the survey in 1995, two aspects of change occurred which showed in interior space only and internalization through interior-specific additions and improvements. An analysis of interior changes demonstrated there was significant change in kitchens, multipurpose rooms, and other spaces focused on housework and homemaking. Internalization through interior-specific is showed in balcony. As family member is increasing, it is intended to be increasing size of interior space; however, it is showed to increase size of interior space in the step that family member is reducing. It is reason that more spaces are needed when their children whose the old are living in detached houses of rural area are visited.

이 논문은 HMIPv6를 위해 효율적인 새로운 멀티캐스트 방안을 제안한다. 이동할 영역의 MAP이 멀티캐스팅을 지원하지 않는다면 그 영역으로 이동하는 그룹의 구성원은 그 MAP을 통해 멀티캐스트 그룹에 가입할 수 없게 된다. 따라서 그룹 구성원은 멀티캐스트 패킷을 계속 수신하기 위해, Mobile Ipv6를 사용하여 자신의 HA로부터 패킷을 수신한다. 그러나, 이것은 BU 메시지의 전달 지연 시간을 증가시키는 요인이 될 수 있다. 우리가 제안하는 방안은 새 영역의 MAP이 멀티캐스팅을 지원하지 않을 경우, HA에서 패킷을 받지 않고 이전의 멀티캐스트 MAP에서 수신하도록 한다. 제안하는 방안은 터널링 비용, 총 전달 비용, 핸드오버 지연 시간 등을 줄일 수 있다. 전달 비용과 핸드오버 지연 시간 등을 사용하여 M-HMIPv6 방안과 성능을 비교 측정하였다

How do party organizations respond to newly evolving social groups? Research on Indian party organizations reveals that in multiethnic societies with uneven modernization between social groups, internally competitive parties respond better to newly evolving groups. Moreover, it is claimed: the same dynamic works vis-$\grave{a}$-vis homogenous societies with cleavages based on economic differences; and, the pattern holds regardless of differences in electoral institutions. This study examines these claims by testing whether factional competition correlated with recruitment into Japan's Liberal Democratic Party in 1972 and 1983. Japan had a single-nontransferable-vote system with multi-member districts, while the research on India assumes a first-past-the-post system with single-member districts. This study conducts a difference of means test on the population of new and old politicians in the LDP in 1972 and 1983 with a pooled variance adjustment to account for differences in populations' size. The findings show that intra-party competition and recruitment are not correlated in Japan, thus tentatively rejecting both claims.
