In South Korea, regulations on gambling have been implemented since the beginning of the Game Rating Board, and they have been improved, newly enacted or deleted according to the current game industry. For instance, regulations on arcade games include that no more than 10,000 KRW can be input per hour, automated operation is prohibited, results cannot be saved, money exchange is prohibited, etc. The study aimed to relieve excessive regulations on gambling arcade games in South Korea such as unnecessary regulations and duplicate regulations in a practical way. It is therefore expected to contribute to implementing regulation plans for gambling games suitable for the level of consciousness of the South Korean people.

This study examines the effect of environmental regulation considering the endogeneity on the productivity of Korean manufacturing industry based on the Porter hypothesis using data from the Mining and Manufacturing Survey, Survey of Research and Development in Korea, and Environmental Statistics Portal from 2003 to 2013 with fixed effect model. In order to eliminate the bias of the missing variables that may occur in the existing studies, we analyze factors affecting productivity such as market competition, R&D investment as explanatory variables. And, in order to eliminate measurement error and inverse causality, we use instrumental variable approach. The main results are as follows. First, our findings that the environmental regulation improve the productivity of Korean manufacturing in the long-run support the Porter hypothesis. Second, our findings suggest that measurement error and reverse causality are main sources of the endogeneity, while omitted variable is not. Finally, environmental technology R&D has reduced productivity in the short-run.

본고(本稿) 1981~92년의 부당한 공동행위(共同行爲) 및 사업자단체금지행위(事業者團體禁止行爲) 심결례(審決例)들을 통해 우리나라 사업자들의 담합(談合)패턴과 특징(特徵)을 살펴보고 이를 바탕으로 담합규제법제(談合規制法制)와 그 운용상(運用上)의 문제(問題)들을 검토하여 담합규제(談合規制)의 실효성(實效性) 제고(提高)를 위한 경쟁정책적(競爭政策的) 대안(代案)들을 제시하고 있다. 우리의 담합규제법제(談合規制法制)와 법시행방법(法施行方法)은 은밀하고 지속적인 담합(談合)보다는 담합(談合)의 직접적 증거를 남길 가망이 많은 명시적(明示的) 공모행위(共謀行爲)의 적발(摘發)로 기울어져 있는 것으로 보인다. 사실, 담합사건(談合事件)들이 경쟁적(競爭的) 시장(市場)에 편재(偏在)되어 있고 사업자간(事業者間) 및 사업자단체(事業者團體) 공동행위(共同行爲)의 평균공모기간(平均共謀期間)이 각각 8개월과 10.7개월에 지나지 않는다는 것은 적발 시정조치된 행위(行爲)가 주로 담합(談合)의 시도(試圖)였음을 시사하는 것이다. 또한 가격고정공모(價格固定共謀)의 평균가격인상율(平均價格引上率)이 18%임을 감안할 때 담합실행기간(談合實行期間) 매출액(賣出額)의 1%라는 현재의 최고(最高) 과징금액(課徵金額)은 부당이득환수(不當利得還收)나 행정제재(行政制裁)의 어떤 측면에서도 그 실효성(實效性)이 극히 의심스러운 적은 금액이며, 거의 모든 위법행위(違法行爲)에 대하여 시정조치(是正措置)만이 취해지고 담합사업자(談合事業者)들에게 과징금(課徵金)이나 형사벌(刑事罰)이 부과되는 경우도 극히 드물어 담합억지효과(談合抑止效果)가 의문시되고 있다. 담합규제(談合規制)의 실효성(實效性) 제고(提高)를 위해서는 경쟁(競爭)의 실질적(實質的) 제한성(制限性)이 아니라 경쟁제한(競爭制限)의 부당성(不當性)을 위법성(違法性) 판단기준으로 하여 가격고정(價格固定), 입찰조작(入札操作), 시장분할(市場分割) 등 '적나라한' 담합(談合)에 대한 당연위법원칙(當然違法原則)을 확립하고, 과징금(課徵金)을 담합기간(談合期間) 매출액(賣出額)의 20% 정도로 상향조정(上向調整)하여 담합(談合)에 대한 핵심적 제재수단(制裁手段)으로 활용하여야 한다, 또한 담합(談合)의 적발(摘發) 입증노력(立證努力)에 경제적(經濟的) 분석(分析)과 증거(證據)를 이용하고, 특히 입찰조작(入札操作)의 감시(監視) 적발체제(摘發體制)를 확립하여 공공조달분야(公共調達分野)에 대한 경쟁정책(競爭政策)을 강화해야 하며, 묵시적(默示的) 담합(談合)을 가능케 하면서도 합의(合意)로 간주될 수 없는 담합촉진(談合促進) 기도행위(企圖行爲)를 금지할 법적(法的) 근거(根據)를 마련해야 할 것이다.

The variable message sign(VMS) is a facility to smoothen traffic flows and enable safe passing by providing real-time necessary information on roads, weather, transportation, and traffic regulations. The VMS also solves a feeling of uneasiness and gives a sense of psychological security by providing information to drivers. However, the VMS has a strong character of being a non-market product but a public product, so it has not normally been evaluated for its value. This research has evaluated a value of satisfaction level for traffic information users, using a contingent valuation method(CVM). As a result of evaluating the value of satisfaction level for users through division into an urban roadway and an urban highway for the cities where an intelligent transportation system(ITS) has been established, the urban highway had a value of 96.7 won/system and the urban roadway had a value of 76.3 won/system.

Analysis of the economic impact on Korean bioindustry companies was approached after Korea access to the Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization to the Convention on Biological Diversity (hereinafter 'the Protocol') enters into force. Cost analysis of the economic impact is based on the size of bioindustry market, dependency ratio on genetic resources abroad, ABS (Access and Benefit Sharing) ratio for royalty ratio. Korean bioindustry companies would have had to pay extra ABS cost around 1.3-6.0 billion won for using genetic resources abroad, if the Protocol had entered into force in 2009. And this cost is estimated to be around 13.6 - 63.9 billion won in 2015. All ABS costs account only about less than 0.01% of total Korean bioindustry volume of target years. These show us that joining the Protocol will not significantly impact the bioindustry market in Korea. If the Protocol enters into force, genetic resources users have to pay PIC (Prior Informed Consent) and MAT (Mutually Agreed Terms) cost before accessing the genetic resources outside of their country, regardless of the accession status of the country. This ABS costs and terms on provided genetic resources will be determined by compliance between genetic resources users and providers. As a genetic resources provider, Korean bioindustry companies will have advantage over technology transfer agreements, royalties, licensing agreements, and taxes on profits from patents including traditional knowledge. Also, Korean bioindustry companies are expected to get various socio-economic benefits such as patent litigation and regulatory proceedings as a genetic resources provider. Considering the advantages and disadvantages of the Protocol that Korean bioindustry companies will face together, the socio-economic impact of the Nagoya Protocol on Korean bioindustry companies is negligible regardless of the accession status of Korea to the Nagoya Protocol.

This paper purports to analyze the economic rationale of compensating balance requirements and its impact on money supply. This practice has recently been severely criticized for artificially increasing the money supply and, therefore, limiting the nation's aggregate lending policy under the tight constraint of the given money supply target. A review of the existing literature implies that compensating balance requirements is a banking practice which leads to corrections in the distortion of financial resource allocation due to the imperfection of financial market stemming from asymmetric information and/or financial regulations on deposit and lending rates. Therefore, the economic rationale of this practice is deemed to improve the efficiency of financial resource allocation. On the other hand, the macroeconomic impact of compensating balance requirements on the money supply depends on the impact on the money multiplier, which in turn depends on the desired ratio of deposit that people wish to maintain on the money borrowed from the banking system, and on the desired reserve ratio that the banking system would like to hold for deposit withdrawal. If the compensating balance requirements could increase the desired ratio of deposit to borrowing (bank lending), it will increase the available amount of total reserve within the banking system and, in turn, the money multiplier. However, this channel has not been fully analyzed in the literature, and the direction of the effect is ambiguous. If the practice could reduce the turn-over rate of deposit and, thereby, reduce the desired reserve ratio of the banking system, then it will also increase the money multiplier. While this channel operates unambiguously toward increasing the money multiplier, this effect will be limited by the extent that the banking system holds the excess reserve over the required reserve because the excess reserve will set the maximum amount for the desired reserve to fall. This paper tries to determine the effect on the money supply by empirically estimating the multiplier and the desired ratio of deposit to lending equations as functions of the ratio of compensating balance to the related lending, which is not observable and is estimated for the regression purpose. The results suggest that the effect of compensating balance requirements on the money supply in Korea does not exist or is very tenuous even if it could operate. Therefore, this paper concludes that the well publicized policy of cross cancelling the compensating balance and the related lending will not be effective at controlling the money supply and increasing the amount of loans without expanding the money supply.

The purposes of this study were to examine effective variables influencing on adolescents' mobile phone addiction. The subjects were the 666 middle or high school students who had their own mobile phone in Gwangju. Data were analyzed with frequency, percentage, cronbach's ${\alpha}$, mean, SD, pearson's correlation and multiple regression using SPSS/PC WIN 14.0 program. The major findings were as follows: 1. The most frequently used function of student mobile phones was text message and they used text message more than 41 times a day. Mostly they were talking to the same sex friends on the phone and the monthly charges ranged from 20,000 to 30,000 won. In general, they called to their friends after school. Their parents' attitudes toward their mobile phone using showed that the most of their parents did not care about their children's mobile phone use. The restriction of using their mobile phone at school was normal. 2. The average scores of mobile phone addiction were lower than median(3.0) and self esteem, self control, family strengths, peer conformity and school life adaptation were higher than median. 3. The adolescence's mobile phone additions were influenced by peer conformity, school life adaptation, school levels, sex and self control. And these variables explained to the adolescence's mobile phone additions about 28%.

A frequent flyer program is a loyalty program offered by many airlines. Typically, airline customers enrolled in the program accumulate frequent flyer miles corresponding to the distance flown on that airline or its partners. There are other ways to accumulate miles. In recent years, more miles were awarded for using co-branded credit and debit cards than for air travel. Acquired miles can be redeemed for free air travel; for other goods or services, such as travel class upgrades, airport lounge access or priority bookings. The first modern frequent flyer program was created Texas International Airlines in 1979. This program was also adopted in Korean Air in 1984. Since then, the mileage programs have grown enormously. As of June 2009, the total member of two national airlines in Korea had been over thirty million. However, accumulated miles could be burden of airlines, because the korean corporations should record the annual financial report the accumulate mileage on a liability account by 'the international financial report standards(IFRS)' next year. The korean airlines need to minimize the accumulated miles, so that for instance Korean Airlines SKYPASS-miles expire 5 years after being earned. It means that miles earned on or after July 2008 will expire after five years if unredeemed. Thus, this paper attempt to analyze the unfairness of the mileage rules of korean airlines by examining a specific portion of the conditions relating to consumer protection, because many mileage users has difficulties using mileage programs and complained the amendment of the mileage rules. In conclusion, the contemporary mileage rules in Korea are rather unsatisfactory, because airlines is not only recognizing a mileage into a kind of benefit but also denying inheritance of mileage and the legal nature of mileage as a property right. It is necessary to amend relevant mileage rules in view of consumer protection, because air mileage is not simple benefit but a right of mileage user.

This study is conducted to evaluate economical value of Jeju grassland and validity of its preservation, and draw up several measures to support. To measure its economical value, this study examined its environmental value and social and cultural value. For environmental value, this study used replacement method while it applied CVM method, a widely used method, to assess social and cultural value and two-level two-best choice selection method, which ask questions by assuming virtual circumstances to avoid reflecting some biased opinions. Jeju grassland has multiple functions-environmental functions such as preventing soil corrosion and flood, handling animal excrement, and purifying air, and social and cultural functions such as promoting physical and mental health and providing recreation places. From the results of the feasibility study, Jeju grassland's annual multiple functions are assessed to have a total $397,115{\sim}418,995$ million won worth. In addition, it is found that Jeju visitors recognize Jeju grassland for its functions to contribute to public interests. That is, they think it can provide attractive views and educational and recreational places and promote emotional development. Especially, many people presented their ideas that it be continuously preserved since it is worthwhile for us and our next generations. To preserve grassland's cultural resource, which create a huge economic value like this, the Government has to support a certain amount of financial aid for turning to a better grassland environment and its maintenance to realize environment-friendly livestock farming on Jeju Island and promote its tourism industry and consequently, add more value to Jeju.
