This study is aimed at empirically examining the Korean unionists' solidarity using the survey of 476 full-time workers employed at the unionized workplace. It also questions the determinants affecting the unionist' willingness to be united with the contingent workers. The Korean unionism has faced the biggest challenge, that is, the crisis-in-worker solidarity. Although prior literature has noted the crisis in Korean unionism, it lacks a solid investigation of individual workers' perception of solidarity which may play a key role in building up worker-solidarity in the union movement. This study first examines the three sources of solidarity allowing for the historical and theoretical approach to the modern solidarity; economic interests, worker-identification and empathy, which provide an emprical framework for this study. The empirical evidences shows dynamic aspects as of how the full-timers perceive solidarity with the non-regular workers in the three terms of solidarity. First, full-time unionists share rare willingness to be united with contingent workers in terms of economic solidarity. In addition, the KCTU (Korean Confederation of Trade Unions) with social reformative orientation has little influence on increasing their member's orientation towards solidarity. Second, it is found that full-time unionists have more willingness to identify themselves with the non-regular workers as a member of the labor class. The KTCU is also positively associated with their member's will of identification with contingent workers. Third, the unionists, however, show little empathy toward non-regular workers, which is contrast to the willingness to worker identification. No causality is also found between the KTCU and their members' empathy for the others.

지난해에는 문화관광부의 '도서관정보화추진계획' 발표, '학교도서관살리기국민연대'의 결성, '문화개혁을 위한시민연대'의 도서관 자료구입비 증액 캠페인, 남ㆍ북도서관협회 대표단의 역사적인 회합 등 도서관발전을 위한 각계 각층의 관심이 활발했던 한 해 였다. 하지만 '저작권법시행령' 개정공표로 도서관에서의 복제전송 문제가 불거지고 '도서관및독서진흥법'의 개정으로 '도서관및독서진흥위원회'와 '도서관및독서진흥기금'이 폐지되어 도서관계를 안타깝게 하기도 하였다. 그 어느때보다도 도서관의 사회적 역할이 증대되고 있는 지금, 우리 도서관계 각 단체의 올 한해 각오와 사업방향 등을 알아보았다. 편집자 주

Luminescence dating is based upon the premise that several commonly occurring minerals (e.g. quartz and feldspar) can be used as natural dosimeters, recording the amount of radiation to which they have been exposed. We report results of optical dating on quartz samples separated from archaeological remains (burnt soils and potteries), which were excavated at Myungam-Ri, Asan, and Chungnam province and at Sayang-Ri, Chinchun, Chungbuk province, considered as the cultural site of the early Bronze Age. The resultant dates were in good agreement with the ages derived by archaeological assessment. It is concluded that the optical dating introduced in here should contribute significantly to future archaeological dating work.

해외로 부터 대량의 방위장비 조달이라는 발상은 일본의 주식인 쌀의 수입 이상으로 약간은 당돌하게 느껴지는 사람도 있을 것이다. 그러나 일본으로서는 군사침략을 받는다고 가상한 최악의 사태에, 필요하고도 충분한 방위장비품이 자연스럽게 확보될수 있는 방안을 확립해두는 조치가 바람직하다. 그 구체적이고 실현가능한 처방전으로서 방위장비품을 해외에서 생산하는 구상은 그 의의를 평가받아야 한다. 또한 방위장비품을 국제조달함으로써 우호국간에 강력한 연대관계가 빚어지는 점에도 착안하여야 한다.

Terrestrial magnetism has left traces through residues such as fossils of the terrestrial magnetism as time went by. An analysis of archaeological terrestrial magnetism is an estimation of dates of archaeological remains where baked earth is exposed by measuring the change of the past terrestrial magnetism through thermo-remnant magnetization of baked earth. This paper attempts to apply an analysis of the archaeological terrestrial magnetism to archaeological remains using fourteen soil samples extracted from a charcoal kiln with side window located at the Area Ⅰ of Maegokdong. The date of A.D.440${\pm}$15 the analysis of archaeological terrestrial magnetism came up with gives solid evidence, while an archeological chronicle used arrangements of surrounding artifacts because of the absence of remains and assumed uncertainly that a charcoal kiln with side window was from the three kingdom periods. This analysis of archaeological terrestrial magnetism has come to anchor as a main natural scientific analysis because it relatively easily removes pollutants and comes up with highly reliable results owing to its considerably narrow error tolerance of assumed dates.

Erroneous fission-track (FT) ages caused by an inappropriate calibration in the initial stage of FT dating were redefined by re-experiments and zeta calibration using duplicate samples. Revised FT zircon ages newly define the formation ages of Yucheon Group rhyolitic-dacitic tuffs as Late Cretaceous to Early Paleocene ($78{\pm}4$ Ma to $65{\pm}2$ Ma) and Gokgangdong rhyolitic tuff as Early Eocene ($52.1{\pm}2.3$ Ma). In case of the Early Miocene volcanics, FT zircon ages from a dacitic tuff of the upper Hyodongri Volcanics ($21.6{\pm}1.4$ Ma) and a dacitic lava of the uppermost Beomgokri Volcanics ($21.3{\pm}2.0$ Ma) define chronostratigraphies of the upper Beomgokri Group, respectively in the southern Eoil Basin and in the Waeup Basin. A FT zircon age ($19.8{\pm}1.6$ Ma) from the Geumori dacitic tuff defines the time of later dacitic eruption in the Janggi Basin. Based on FT zircon ages for dacitic rocks and previous age data (mostly K-Ar whole-rock, partly Ar-Ar) for basaltic-andesitic rocks, reference ages are recommended as guides for stratigraphic correlations of the Miocene volcanics and basements in SE Korea. The times of accumulation of basin-fill sediments are also deduced from ages of related volcanics. Recommended reference ages are well matched to the whole stratigraphic sequences despite complicated basin structures and a relative short time-span. The Beomgokri Group evidently predates the Janggi Group in the Eoil-Waeup basins, while it is placed at an overlapped time-level along with the earlier Janggi Group in the Janggi Basin. Therefore, the two groups cannot be uniformly defined in a sequential order. The Janggi Group of the Janggi Basin can be evidently subdivided by ca. 20 Ma-basis into two parts, i.e., the earlier (23-20 Ma) andesitic-dacitic and later (20-18 Ma) basaltic strata.

Affiliate marketing is classified as a type of online advertising, where merchants share a percentage of sales revenue generated by each customer, who visited the company's website via a content provider. Content provider, referred to as an affiliate, usually places an online advertisement at its website. For the past few years, there have been a lot of companies or individuals who participate in affiliate marketing. Generally speaking, most of them have websites and post the merchant's ads on their own websites. However, building and maintaining websites have some technology requirements. The widespread use of Social Network Service (SNS), especially microblog-based SNS such as Twitter and Sina Weibo, provides opportunities for individuals who want to be content providers of affiliate marketing. Since information spreads quickly on microblog-based SNS and the easy in targeting customers, it is both an effective and an efficient tool to do affiliate marketing. The relationship between a content provider and the potential customer, which is referred as "tie strength", is quite an important issue in such situation. This paper proved that service characteristics of the microblog-based SNS (security, community drivenness and navigability) and content quality all had positive influence on click-through intention, while tie strength played a moderating role. For the group with strong tie, tie strength is crucial in influencing click-through intention. While for the weak tie group, content quality was very important. Finally, we proposed some implications for both academics and practitioners.

최근 NGO의 급격한 성장과 위상이 높아지면서 정부정책과정에서의 NGO와 정부간 역할관계는 각 분야에서 활발하게 논의되고 있다. 그럼에도 불구하고 교통분야에 대한 NGO와 정부간 역할관계에 관한 관심이나 연구가 매우 미흡한 실정이다. 이와 같은 배경에서 수행된 본 연구는 현재 열악한 대중교통서비스를 개선하기 위해서 NGO와 정부간 정책연대 등 새로운 정책운용의 필요성을 제시한 탐색적 연구이다. 본 논문의 분석결과, 우선 대중교통정책 운용은 ‘공급자중심’에서 ‘이용자중심’으로 전환되어야 한다. 이를 위해서는 ‘서울시를 비롯한 자치단체들이 NCO와 정책연대를 통해 정책추진에 시민의견을 적극 반영하는 제도적 장치가 강구되어야 한다. 구체적으로는 서울시의 경우 교통·환경·소비자 등 관련분야의 NGO와 서울시 및 의회관계자, 전문가, 업계대표 등이 참여하는 가칭 ‘대중교통시민위원회’를 구성한다. 또한 지방자치단체는 대중교통 전반의 서비스 개선목표와 단계별 세부추진사항을 결정, 헌장으로 제정하고 이를 토대로 대중교통정책의 집행과정과 성과를 주기적으로 평가하고 시정 조치할 필요가 있다.

From the K-Ar age determinations for the clay deposits and their surrounded rocks in southwest Korea, the ages of the ore formation in all clay deposits fall in very narrow range from 78.1 to 81.4 Ma. K-Ar ages of clay deposits are slightly younger than those of the Cretaceous volcanic rocks (Hwangsan Formation, 81.4 to 86.4 Ma) and are slightly older than those of the Cretaceous granitic rocks (77.1 to 81.5 Ma). These results indicate that clay deposits were formed with genetical relation to late Cretaceous felsic magmatism. Weolgagsan granite, which has been previously considered to be Cretaceous, is proved to be formed its age in Jurassic (140.9 and 144.8 Ma). The close relationships of K-Ar ages between the clay deposits and Cretaceous granitic rocks suggest that the clay deposits were formed during the hydrothermal alterations caused by the thermal effects (hydrothermal circulation) of the granitic intrusions rather than by the hydrothermal activities associated with volcanic activities.

The present study was carried out to investigate the improvement of major production traits with the published data of twenty-two years'random sample tests held in Korea from 1966 to 1988. Eight traits-roaring viability, laying viability, age of sexual maturity, hen day egg production, hen-housed egg production, egg weight, feed requirement, 500 days body weight-were dealt with in this study. The results obtained in this study are summerized as follows； 1. Total mean value for rearing viability was 99.4% in 1980s. Mean value for rearing viability of colored hen was 99.5% and white hen was 99.06% in 1980s. Mean value for laying viability was increased by 0.98%, 0.86% and 0.86% per year in pool data, white hen and colored hen, respectively. 2, Age of sexual maturity was decreased from 171.1 day to 160.8 day in pool data during 1960s- 1910s but increased to 162.4 day in 1980s； and decreased from 160.5 day to 1595 nay in white hen but increased from 163.7 day to 166.1 day in colored hen during 1970s-1980s. 3. Mean values for hen-day egg production were increased by 0.96%, 1.09% and 0.63% per year in pool data, colored hen and white hen, respectively. 4. Mean values for hen housed egg production were increased by 45, 5.37 and 4.23 per year in pool data, colored hen and white hen, respectively. 5. Egg weight were improved by 0.22g and 0.25g per year in pool data and colored hen but decreased by 0.03g in white hen. 6. feed requirement were improved by 0.04, 0.05 and 0.1 per year in pool data, white hen and colored hen, respectively. 7. 500 days body weights were increased by 0.38g per year in pool data but decreased by 14.95g and 10.37g in colored hen and white hen, respectively. 8. Estimate of correlation coefficient between age of sexual maturity and other factors such as hen day egg production. hen housed egg production, egg weight and 500 days body weight were -0.4512, -0.2876, -0.4376 and 0.2045 in pool data； -0.358, -0.1530 0.3475 and 0.1208 in white hen； 0.0989, 0.1181, 0.2885 and 0.2248 in colored hen, respectively. Estimates of correlation coefficient between hen day egg production and egg weight were 0.6233, -0.2259 and 0.2973 in Pool data, white hen and colored hen； between hen day egg production and 500 days body weight, 0.2417, 0.0774, -0.4787 ： between hen-housed egg production and egg weight, 0.6171, -0.2706, 0.4579： between hen housed egg production and 500 days body weight, 0.3082, -0.0792, -0.3368： between egg weight and 500 days body weight, 0.2742, 0.2205, 0.1354, respectively.
