Air exclusion test which is the way to assess the quality of the concrete is a part destructive test for minor damaging and accurate measurement. it has been well known but the test process is complexed, so it has been well known in foreign country but it is not usable in our country. For this experiment, it analyze its special quality through the inspection for the factor which effect to the result or accuracy for the Air exclusion test, and it examine through the experiment for the Non destructive test and cylinder compressive test which is different from the air exclusion test. We suggest the suitable classified table for the domestic concrete condition through the comparative analysis against the overseas result that has been suggested before.

The ratio of suicide among the elderly in Korea has nearly tripled within the last 20 years. With this in mind, this study examined the effects of social exclusion on depression and suicidal ideation among the elderly living in elderly-only households with a focus on gender differences. Social exclusion is composed of economic, health, housing, education, social participation, and relational aspects. For this study, data were gathered from 527 participants aged 65 years and over. The statistical methods used for data analysis were descriptive statistics, chi-square test, t-test, and hierarchical regression analysis with the SPSS Win 20.0 program. The results of this study are summarized as follows: First, more than 80% of the elderly experienced social exclusion. Women were shown to be more vulnerable than men in terms of housing exclusion, educational exclusion, health exclusion, and multiple exclusion, whereas men were more vulnerable than women in terms of social participation exclusion. Second, social exclusion had significant effects on suicidal ideation among the Korean elderly. We also observed gender differences in the results. Regression analysis of suicidal ideation showed that relational exclusion had a significant effect on suicidal ideation in men, whereas health exclusion had a significant effect on suicidal ideation in women. Results of the study show that stronger social support networks and policies focusing on the elderly are needed in order to reduce elderly suicide in Korea.

Purpose: This study explores how cognitive impairment caused by social exclusion experience can be explained through cognitive narrowing and how it influences consumer's judgment and reasoning and results pseudodiagnosticity bias towards distribution brands. This study examines the characteristics of cognitive narrowing, which is one of the strategies for overcoming the negative emotions resulting from social exclusion, and how cognitive errors called pseudodiagnosticity bias occur due to cognitive narrowing in the evaluation of distribution brands. Research design, data and methodology: Present study was performed with 77 college students in Seoul. Participants were randomly assigned to the group who experienced social exclusion and the group who did not experience social exclusion. The analysis has been made of how the degree of bias of pseudodiagnosticity differs according to the experience of social exclusion by t-test. Results: The group who experienced social exclusion had a higher level of pseudodiagnosticity bias towards distribution brands than the group who did not experience social exclusion. Conclusions: This study confirmed what characteristics of cognitive narrowing, which is one of the strategies for overcoming the negative emotions resulting from social exclusion, and how cognitive errors called pseudodiagnosticity bias occur due to cognitive narrowing. Implications and future research directions were discussed and suggested.

기존 연구들은 사회적 배제가 친사회적 행동에 미치는 영향에 대해 엇갈린 결과를 보고했다. 일부 연구들은 사회적 배제가 부정정서를 유발하고 친사회적 행동을 감소시킨다고 제안했으나 다른 연구들은 친사회적 동기와 행동의 증가를 보고했다. 이러한 상반된 결과는 친사회적 행동이 항상 관계회복과 사회적 재연결(social reconnection)로 이어지지는 않기 때문일 것이다. 친사회적 행동은 소속감 획득의 주요 수단이지만 배제상태에서 관계회복을 기대할 수 없다면 친사회적 행동은 불필요할 것이다. 배제 혹은 소속의 이분법적 상태만을 규정한 기존 연구와 달리 본 연구에서는 사회적 재연결 가능성이 존재하는 배제 위기 상황에서 친사회적 행동을 검증했다. 아울러 집단에 대한 기여 가능성을 보여주는 개인의 능력을 추가적인 독립변인으로 사용했다. 사회적 배제 위기와 참가자의 능력을 조작하기 위해 '조합원 되기'라는 시뮬레이션 게임을 실시했다. 참가자들은 인성검사로 지칭한 설문에 응답한 결과를 참고하여 상호 예비투표를 실시했고, 득표수로 배제 위기를 조작했다. 이후 조합원 능력검사로 지칭한 지각검사 결과를 공개하여 능력수준을 조작했다. 실험 1, 2에서 모두 배제 위기가 높고 능력이 낮은 참가자들이 더 많은 기부금을 약정하는 친사회적 행동을 보였다. 이 결과들은 사회적 배제 위기 상황에서 재연결 가능성이 친사회적 행동을 설명하는 핵심 변인임을 보여준다.

본 연구는 사회적 배제의 잠재유형을 구분하고 노후의 경제적 불안에 미치는 영향을 실증적으로 분석하였다. 또한 주관적 계층의식에 따라 그 영향력이 달라지는지를 함께 살펴보고자 하였다. 이를 위해 2016년 한국종합사회조사(KGSS) 14차 자료를 사용하여, 조사 당시 기준 만 18세의 성인남녀 1,041명의 응답지를 분석하였다. STATA14와 MPLUS 7 통계프로그램을 이용하여 기술통계분석과 t-test, 잠재계층분석(LCA), 잠재집단에 대한 다항로지스틱분석을 실시하였다. 마지막으로 다중회귀분석을 실시하여 변수 간 영향관계 및 조절 효과를 확인하였다. 연구결과 사회적 배제의 유형은 3집단으로 나타났으며, 사회활동배제집단(49.3%), 다차원적 배제집단(30.9%), 사회 활동 적극집단(19.7%)의 순으로 나타났다. 사회활동배제집단은 경제, 고용, 건강 배제의 가능성이 가장 낮지만, 공식/비공식 사회활동의 배제가 두드러진 집단이며, 다차원적 배제집단은 모든 영역에서 배제를 경험할 가능성이 50% 이상인 집단으로 나타났다. 사회활동 적극집단은 비공식 사회활동에 매우 적극적으로 참여하는 것이 특징인 집단이다. 다항로지스틱 분석결과 사회활동배제집단은 다른 집단에 비해 청년층이 많이 포함되었으며, 다차원적 배제집단에는 배우자가 없는 여성노인이 많이 포함되어 있는 것으로 나타났다. 마지막으로 다중회귀분석 결과 사회적 배제 유형은 주관적 계층의식과 상호작용하여 노후의 경제적 불안에 영향을 미치는 것으로 나타났다. 이러한 연구결과를 바탕으로 노후의 경제적 불안을 예방하기 위한 정책적·실천적 방안을 제언하였다.

This study is aimed to estimate market integration of wild caught fish species on the Korean market, using both multivariate and bivariate cointegration analysis. For the analysis of market integration between wild caught fish species, major four fish species those are most popular fish in the market and caught by the large purse seine fishery-chub mackerel, jack mackerel, hairtail and spanish mackerel-were selected as analytical target fish species. And their real monthly price data from January 2000 to December 2011 were used in the analysis. The results of the multivariate cointegration test for four wild caught fish species showed that there would be long-term equilibrium relationships among prices of four wild caught fish species, and consequently, the markets for wild caught fish species were estimated to be integrated. The results of exclusion test and bivariate cointegration test also supported that there would be a clear evidence to suggest that all target wild caught fish species were cointegrated each other.

This article intends to analyse some features in Exclusion Clauses of the Institute Cargo Clauses 2009 and the results of analysis are following. First, the insufficiency of packing or preparation exclusion under the revised Clause 4.3 is now more limited than before and the Clause suggest the test of sufficiency or suitability "to withstand the ordinary incidents of the insured transit". Secondly, the word "proximately" was deleted under the revised Clause 4.5 for the insurer to be identified more easily as a cause, but it remains to be seen whether that re-drafting will be successful. Thirdly, The exclusion under the revised Clause 4.6 does not apply unless the insurer can prove that, at the time the subject-matter insured is loaded on board the vessel, the assured was aware, or in the ordinary course of business should have been aware, that the relevant insolvency or financial default could prvent the normal prosecution of the voyage, and to a person who purchase the goods from the assured in good faith under a binding contract. Fourthly, the exclusion in respect of unseaworthiness of vessel under Clause 5.1.1 applies only where the assured is privy to the unseaworthiness, whereas the exclusion in respect of unfitness of container or conveyance under Clause 5.1.2 includes the privity of the employee. Finally, Clause 7 establishes the definition of terrorism, and adds ideological and religious motive to political motive.

This study is aimed to estimate price interactions between wild caught fish and farmed fish on the Korean seafood market, using multivariate cointegration analysis. Major commercially important four wild caught fish (chub mackerel, hairtail, yellow croaker and spanish mackerel) and two farmed fish(oliver flounder and black rockfish) are selected as analytical target fish species. Between 2000 and 2013, monthly production and price data are used in this study. The results of cointegration test showed that there would be a long-term equilibrium relationship among 4 wild caught fish and 2 farmed fish. However, the results of exclusion test indicated that farmed fish might not contribute significantly to the long-run relationship, suggesting that farmed fish might be only a weak substitute for wild caught fish, but no significant interaction could be found.

KSNPs(Korea Standard Nuclear Power Plant) have been applied the break exclusion criteria to the high energy lines passing through containment penetration area to ensure that piping failures would not cause the loss of containment isolation function, and to reduce the resulting dynamic effects. Systems with the criteria are the Main Steam system, Feed Water system, Steam Generator Blowdown system, and Chemical & Volume Control system. In accordance with FSAR(Final Safety Analysis Report), a 100% volumetric examination by augmented in-service inspection of all pipe welds appled the break exclusion criteria is required for the break exclusion application piping. However, it is difficult to fully satisfy the requirements of inspection because 12", 8" and 6" weldolet weldments of Main Steam pipe line have complex structural shapes. To resolve the difficulty on the application of conventional UT(Ultrasonic Testing) technique, realistic mock-ups and UT calibration blocks were made. Simulations of conventional UT were performed utilizing CIVA, a commercial NDE(Nondestructive Examination) simulation software. Phased array UT experiments were performed through mock-up including artificial notch type flaws. A phased array UT technique is finally developed to improve the reliability of ultrasonic test at main steam line pipe to 12", 8" and 6" branch connection weld.

To develop an efficient DNA typing system for Chinese Holstein cattle, 17 microsatellites, which were amplified in four fluorescent multiplex reactions and genotyped by two capillary electrophoresis injections, were evaluated for parentage verification and identity test. These markers were highly polymorphic with a mean of 8.35 alleles per locus and an average expected heterozygosity of 0.711 in 371 individuals. Parentage exclusion probability with only one sampled parent was approximately 0.999. Parentage exclusion probability when another parent' genotype was known was over 0.99999. Overall probability of identity, i.e. the probability that two animals share a common genotype by chance, was $1.52{\times}10^{-16}$. In a test case of parentage assignment, the 17 loci assigned 31 out of 33 cows to the pedigree sires with 95% confidence, while 2 cows were excluded from the paternity relationship with candidate sires. The results demonstrated the high efficacy of the 17 markers in parentage analysis and individual identification for Chinese Holstein cattle.
