이철진 ( Chul Jin Lee ),최재우 ( Jae Woo Choi ) 대한관광경영학회 2015 觀光硏究 Vol.30 No.3

본 연구는 국내 관광자를 둘러싼 최근 관광환경의 가장 큰 특성이라고 할 수 있는 SNS를 통한 관광정보 활용의 중요성 지각을 기초로 하여, SNS를 통한 관광정보가 관광자 개인 및 사회적 여건과 관련한 제약의 인식을 통해 관광행동의도에 미치는 영향을 검증하기 위한 것이며, 이러한 연구의 목적을 달성하기 위하여 SNS관광정보를 경험하고 활용하여 국내관광을 체험한 관광자 302명을 대상으로 분석한 결과로 다음과 같은 시사점이 도출되었다· 첫째, SNS관광정보가치의 기능성은 관광자의 내재적 제약에 완전매개하여 관광행동의도에 영향을 미치는 결과가 도출되었으며, 둘째, SNS관광정보가치의 상징성은 관광자의 인간상호적 제약에 완전매개하여 관광행동의도에 영향을 미치는 결과가 나타났고, 마지막으로 전체적인 분석과정에서 SNS관광정보가치와 관광행동의도 간 관계에서 관광자의 지각된 제약요인의 부분적매개효과가 나타났다· 관광정보와 관광자의 제약, 행동의도 간 관계를 통해 SNS관광정보의 효용성과 가치를 검증하고, 정보와 제약, 행동 간 단계적 구조를 기초로 하여 분석모델을 수립하였다는 점에 시사하는 바가 크다고 사료된다· 이에 후속하여 SNS관광정보가치와 관광자의 심리적 체계 간조절역할 규명의 필요성과 국내 외 관광을 포괄하고 표본의 한계 등을 극복한 일반화된 연구가 필요하다고 사료된다· This study was conducted to verify how the tourist information on SNS influences the tourists`` behavioral intentions through the perception of Constraints related to the individual tourists and the social circumstances, based on the perception of importance of use of tourist information on SNS, which is the biggest characteristic in the latest tourism environment surrounding the local tourists in Korea. In order to achieve this purpose, 302 local tourists who viewed and used the tourist information on SNS and the following were the findings: First, the functionality of tourist information on SNS completely mediated the tourists`` Intrapersonal Constraints to affect their behavioral intentions. Second, the symbolism of tourist information on SNS completely mediated the tourists`` Interpersonal Constraints to affect their behavioral intentions. Finally, in the overall process of analysis, the tourists`` perceived Constraints factors showed partial mediated effect in the relation between the value of tourist information on SNS and tourists`` behavioral intentions. The usability and value of tourist information on SNS were verified through the relation between tourist information and tourists`` Constraints and behavioral intentions. This study is significant in that it established an analytical model based on a hierarchical structure of information, Constraints, and behaviors. Follow-up studies would need to clarify the control between the value of tourist information on SNS and the tourists`` psychological systems and generalize the information by including local and international tourism and overcoming the limitation of samples.

The purpose of this research was to develop a flat panel display device’s glass etchant which can replace hydrofluoric acid. The glass etchant was composed of 18~19% wt% of ammonium hydrogen fluoride, 24~25 wt% of sulfuric acid, 45~46 wt% of water, 4~5 wt% of sulfate and 7~8 wt% of fluoro-silicate. By replenishing the etchant which has the amount of 5% of initial solution’s mass, it was possible to reuse the etchant continuously. The developed etchant showed 5μm/min of etching rate at 30 ℃. The reusable etchant, with replenishing 5% of initial etchant mass showed the stable etching rate, which has the deviation of less than 0.1 μm/min etching rate. The glass surface of flat panel display device created from our etching process was in good condition with any defects such as pin hole and dimple.

This study is to evaluate clinical and arthroscopic second-look results of arthroscopic repairs of posterior root tears of medial meniscus which may cause loss of circumferential hoop tension and extrusion of meniscus. From October 2006 to May 2009, fifty-eight patients (59 knees) underwent arthroscopic pull-out repairs. Clinical results were evaluated using Hospital for Special Surgery (HSS) score and International Knee Documentation Committee (IKDC) score for 12-month follow-up. Second-look arthroscopy was done to evaluate meniscal healing in 21 cases. Magnetic resonance imaging (MRI) was performed to assess status of repaired meniscus and tibial tunnel position in 9 patients. Average preoperative HSS score and IKDC score of 59 cases were 69.5 and 36.0, respectively. Average postoperative HSS score and IKDC score of 59 cases had been changed into 90.3 (p<0.001) and 66.8 (p<0.001), respectively. Second-look arthroscopies revealed complete or incomplete healing except one case. Two patients showed increased one grade according to the Kellgren-Lawrence radiologic classification system and others showed no change. Of 9 patients who performed MRI, six patients showed complete healing. The average position of tibial tunnel was 4.8 mm anterior and 5.7 mm medial to center of posterior cruciate ligament. Arthroscopic pull-out repair technique using transtibial tunnel seems to be simple and effective procedure for posterior root tear of medial meniscus. Further evaluation of arthroscopic repair of posterior root tear of medial meniscus should be needed to prove the effectiveness on the prevention of osteoarthritis of knee.

청년고용촉진장려금 효과 분석

본 연구는 청년층의 고용촉진을 위한 재정투입 사업으로 2004년에 도입된 신규고용촉진장려금 사업의 효과를 탐색-매칭 모형의 틀 내에서 이해한 후, 준실험적 프로그램 평가 방법론을 실제 행정자료에 적용하여 분석한다. ①구직기간이 3개월을 초과한 청년근로자를 대상으로 구직 후 1년가량 사업주에게 최대 월 60만 원의 지원을 가능케 하는 본 제도의 구조는 기존 연구에서 다뤄지지 않았고, 또한 ② 재정지원 수준면에서 괄목할 만한 사업으로서 의의를 갖는다. 본고에서는 ③ 효과 추정에 그치지 않고 비용-편익 분석을 통해 제도의 총괄적 의의를 검토한다. 주요 분석 결과로서 대략 18일 정도 구직기간이 단축되었고, 임금수준이 3% 정도 향상되는 효과가 발생하였음을 얻었다. 보수적으로 설정된 상황 하의 비용-편익 분석의 결과 또한 표본기간 동안 본 사업의 효과성을 지지한다. 끝으로 본 결과의 해석에 관해 논의한다. This study examines the effects of the “youth unemployment bonus” program implemented in 2004. We view this program through the lenz of search-matching models and apply a quasi-experimental approach to an administrative unemployment insurance database of Korea. This episode is particularly useful because the program aims at long-term unemployed youths and the size of public assistance is large enough to subsidize employers for a year with a monthly subsidy of about $600. The main effects are found to be as follows: (i) the search period gets shortened by 18 days, (ii) the subsequent wage has increased by about three percents, and (iii) a conservative benefit-cost analysis reveals the validity of this program. We interpret these results in the context of general equilibrium models.

미국 작가계약의 주요 쟁점에 관한 연구

An writer’s contract is a contract that a writer enters with a production or broadcasting company. The contract guarantees an income for the writer based on the revenue that the company generates. The progress of information and communication technology (ICT) now causes the broadcasting environment to change at a rapid pace, and is transforming the structure of broadcasting companies’ revenue to include not only advertising fees, but also subscription fees and program/content sales. In the United States, the Writers Guild of America (WGA) has been making sure that changes in the broadcasting environment, such as the emergence of new media and platforms, are adequately reflected in authors’ contracts. The WGA engages in diverse activities to protect the rights and interests of writers, including collective bargaining with filmmaking and broadcast content production companies, arbitration over credit-related disputes, and collection and distribution of residuals. The WGA’s minimum basic agreement (MBA), whose terms are decided through collective bargaining, contains provisions on credits, minimum compensation, the payout of residuals, matters of separation of rights, arbitration, pension plans, medical care funds, location expenses and a host of other matters. Although the number and types of disputes between broadcasting companies and writers continue to increase in Korea, the author’s contract used in the Korean broadcasting industry today still contains only bare minimum and abstract provisions. The Ministry of Culture, Sports and Tourism (MCST) has recently started discussions with the Korea TV and Radio Writers Association, major broadcasting companies and production companies to make a standard author’s contract. Not much progress has been made, however, on important issues. It is crucial to establish an effective and fair standard contract on the basis of adequate feedback from diverse stakeholders and by finding the right balance between the MCST’s policy goals with stakeholders’ interests. In the process, stakeholders may need to refer to the experiences of the WGA and its MBA and find and design institutional measures that will provide sustainable and effective support for writers amid the rapid changes of the broadcasting environment.
