The importance of citation measures has been increasing in the evaluation of scholarly journals and it becomes a major issue for Korean Citation Index (KCI) journals. The Journal Impact Factor (JIF), a widely used measure for academic journals, has a problematic issue that it does not include the number of citations for a paper immediately made in the year in which the cited paper was published. On the contrary, the Diachronous Impact Factor (IMP) includes the number of citations made in the published year, but IMP is a measure for papers published a few years ago, not in the last year. It does not represent the recent value of journals effectively. To overcome these problems, Total Impact Factor (TIF) and Mean Impact Factor (MIF) are proposed as new journal citation indicators. This study calculated the performance of proposed indicators experimentally on KCI data. The result shows that TIF is a promising measure for the multidimensional evaluation of humanities and social sciences journals in Korea because it has high stability by year and includes the immediate citations of the published year.

The Korea Port Economics Association was established in 1985 and has been operated for academic research on port economics and research on port logistics. Marking the 35th anniversary of its establishment, it is necessary to establish a new development strategy for academic societies and academic journals. This study analyzed the current status of publication of the Journal of Korea Port Economic Association, from the first issue of 2017 to the December issue of 2019, the utilization and systematic nature of this journal, and the efforts implemented to improve the quality of the journal. The recognition, utilization, and subject inconsistencies were analyzed to determine the academic value of the journal. The findings suggested the journal's academic excellence, as evidenced by its highest ranking by Journal Impact Factor among agro-oceanography journals (among 77 journals) and marine transport journals (among four journals). Further, the direction of development for this academic journal was presented with reference to research characteristics and specialization efforts.

This study analyzes types of primary sources cited by South Korean civil engineers. The results are as follows: 1) primary sources by preference are academic journal (55.7%), book (15.6%), seminar contents (10.2%). 2) documents published within last 10 years (26.1%) are cited most often. 3) domestic journal is the primary academic journal cited, and the finding is similar in preference of top-ranked primary reference (domestic and foreign combined). 4) In terms of time, domestic sources are preferred for up-to-date publications, and foreign sources for relatively non-recent publications. 5) The indices of influence and extemporaneity for both domestic and foreign sources do not show high numbers simultaneously.

This study started from the awareness of the issue if the citation index newly introduced to evaluate the quality of papers satisfies the proper timing matter, which is a component of performance indicators for the evaluation of government-funded R&D institutes. Accordingly, the study will propose improvement ways to shift the previous evaluation system to quality evaluation for mission-oriented R&D institutes by analysing and using the periodical characteristics such as citation half-life and immediacy index of papers. As a result, it turned out that the speed of academic change is getting faster in proportion to the dependency on the technological development but that the citation speed in the field of public technology is relatively slower and the speed of knowledge transfer in the fields related to industry is faster. In addition, the citation index among the R&D fields showed no differences, and the minimum period for citation index measurement with validity should be over 6 years. The problems of evaluation for mission-oriented R&D institutes were deducted based on the technical and statistical analysis results of the temporal characteristic of citation necessary for quality evaluation of performance among R&D fields. To solve the problems, policy alternatives for object and valid quality evaluation were proposed from the points of evaluation period and evaluation criteria.

With emergence of Internet, social media, and mobile service, the consumers have actively presented their opinions and sentiment, and then it is spreading out real time as well. The user-generated text data on the Internet and social media is not only the communication text among the users but also the valuable resource to be analyzed for knowing the users' intent and sentiment. In special, economic participants have strongly asked that the social big data and its' analytics supports to recognize and forecast the economic trend in future. In this regard, the governments and the businesses are trying to apply the social big data into making the social and economic solutions. Therefore, this study aims to reveal the capability of social big data analysis for the economic use. The research proposed a social big data analysis model and an online consumer sentiment index. To test the model and index, the researchers developed an economic survey ontology, defined a sentiment dictionary for sentiment analysis, conducted classification and sentiment analysis, and calculated the online consumer sentiment index. In addition, the online consumer sentiment index was compared and validated with the composite consumer survey index of the Bank of Korea.

선물시장이 개설된 이후 최근까지 약 2년동안 거래된 주가지수선물 8개의 최근월물에 대한 실제가격과 이론가격과의 괴리율을 분석한 결과 한개의 결제월물을 제외한 1개의 최근월물의 선물가격이 평균적으로 이론가보다 낮게 형성되어 주가지수선물시장이 개설된 이후 대부분의 기간동안 선물가격의 저평가상태가 지속되고 있는 것으로 나타났으며, 선물시장이 양적으로 성장한 97년 10월부터 괴리율의 편차가 더 심화되는 경향도 발견되었다. 가격괴리현상을 이용한 차익거래로 실제 수익을 올릴 수 있었는가에 대한 점증에서는 거래비용에서 유리한 위치에 있는 증권회사의 경우 분석대상 총거래일수 544일중에서 차익거래가 가능했던 거래일은 301일이었고, 거래비용측면에서 상대적으로 불리한 일반투자자의 경우에도 총 190일이나 차익거래가 가능했던 것으로 분석되었다. 이처럼 거래비용을 고려하고도 차익거래로 이익을 실현할 수 있는 기회가 즉시에 소멸되지 않고 상당기간동안 지속되는 것으로 나타났으며, 이는 기관투자가의 선물에 대한 인식 부족과 증권회사의 공매도 제약 둥과 같은 제도적 요인, 그리고 차익거래 수익의 불확실성 등에 따라 차익거래가 활발하게 이루어지지 못한데서 기인한 것으로 보인다. 가격괴리현상과 선물만기일까지의 잔존기간과의 관계는 유의적이어서, 선물만기일까지 잔존기간이 길수록 괴리율이 더 크고 만기일에 접근함에 따라 괴리율은 감소하였다.

펜타클로로페놀의 현재 직업적 노출기준은 $0.5\;mg/m^3$(TLV-TWA)으로 권고하고 있다. 이 수치는 눈, 점막과 상기도의 염증과 발한, 열, 위장 불만, 시각 장해, 중추 신경계와 심혈관계 장해를 유발할 수 있는 급성 독성의 가능성을 최소로 하는 것을 목적으로 설정하였다. Chloracne는 공업용 펜타클로로페놀을 사용하거나 펜타클로로페놀을 생산하는 근로자들에 대해서 보고하였다. 펜타클로로페놀은 피부를 통해서 즉시 흡수되는데, 이 물질의 조직 독성은 펜타클로로페놀을 포함한 용액이나 펜타클로로페놀로 오염된 의류와 접촉된 사람에게서 보고되었다. 따라서 피부경고주석은 적합한 것으로 판단되었다. 펜타클로로페놀의 발암성 잠재력에 대한 명확한 증거는 간세포성과 신장에 가까운 신생물이 관찰된 설치류 생물 검정에서 발견되었다. 그러므로 본 물질은 인간에게 불명확한 관련성을 가진 동물성 발암물질(A3)로 설정하였다. 충분한 자료가 확보되지 않아 감작성 (SEN) 경고주석 또는 TLV-STEL은 권고되지 않았다. 펜타클로로페놀은 생물학적 노출지수(BEIs)가 권고된 물질이다.

This paper presents a methodology for priority decision of performance evaluation of small-and-medium-sized highway bridges. This methodology could be used for establishing a maintenance strategy of those bridges which are not liable to the law of the Special Act on the Safety Control and Maintenance of Establishments and are thought laid under blind spot. The risk index are calculated considering vulnerability and social influence, then the bridges are classified as three types, one requiring immediate evaluation, the other one requiring evaluation within next year, and the third one observing, according to the index. The suggested method was applied to a small bridge under service and its field applicability verified. From this study, it was judged that this methodology could be used appropriately for establishing maintenance strategy and saving the maintenance budget.
