This study takes a critical perspective that current vertical regulatory framework for broadcasting, telecommunications, films and games cannot cope with media development in the age of convergence. Changes in media environment mitigate the uniqueness of terrestrial television causing doubts as to why television contents should be treated more strictly than the rest of media contents. Consensus is being reached that horizontal regulation would be the appropriate regulatory measure for media contents. However, which content should be aligned to what level of regulations have not been fully dealt with. The paper shows that the current regulatory framework which is established according to each delivery platform is no longer valid in convergent media environment. It shows why all content regulation should be applied in platform neutral manner. Then it also suggests both short and long term regulatory changes that need to be made in order to meet the future challenges in media convergence era.

This study provides an in-depth analysis of the impact of the deepening reform and opening-up policies announced at the 20th CPC Central Committee's Plenary Session, particularly focusing on the <Foreign Investment Law> and its effects on the tax decisions and organizational restructuring of Korean companies operating in China. Using a comprehensive literature review and policy analysis, the study compares the dual legal structure and tax differences before and after the implementation of the law, assessing how legal unification has influenced the organizational forms and tax strategies of Korean companies. The findings indicate that the <Foreign Investment Law> has played a crucial role in enhancing legal consistency and tax equity between foreign-invested enterprises and domestic enterprises, thereby enabling Korean companies to manage their operations in the Chinese market more stably and efficiently. Additionally, in the context of the ongoing U.S.-China trade conflict, the law's provision of national treatment and tax benefits has proven to be a significant factor in the survival strategy of Korean companies in China. Future research should focus on empirically examining the long-term effects of this law and its impact on actual corporate performance.

Purpose: In every time radiation therapy set up errors occur because internal anatomical organs move due to breathing and change of patient's position. These errors may affect the change of dose distribution between target area and normal structure. This study investigates the usefulness of body-fix in clinical treatment. Materials and Methods: Among 55~60 aged male patients who has hepatocellular carcinoma in area of liver's couinaud classification, we chose 10 patients and divided two groups by using body-fix or not. When applying body-fix, we maintained a vacuum of 80 mbar pressure by using vacuum pump (Medical intelligence, Germany). Patients had free breathing with supine position. After working to fuse and consist MV-CT (megavoltage computed tomography) with KV-CT (kilovoltage computed tomography) obtained by 5 times treatments, we compared and analyzed set up errors occurred to (Right to Left, RL) of X axis, (Anterioposterio, AP) of Z axis, (Cranicoudal, CC) of Y axis. Results: Average Set up errors through image fusion showed that group A moved $0.3{\pm}1.1\;mm$ (Cranicoudal, CC), $-1.1{\pm}0.7\;mm$ (Right to Left, RL), $-0.2{\pm}0.7\;mm$ (Anterioposterio, AP) and group B moved $0.62{\pm}1.94\;mm$ (Cranicoudal, CC), $-3.62{\pm}1.5\;mm$ (Right to Left, RL), $-0.22{\pm}1.2\;mm$ (Anterioposterio, AP). Deviations of X, Y and Z axis directions by applying body-fix indicated that maximum X axis was 5.5 mm, Y axis was 19.8 mm and Z axis was 3.2 mm. In relation to analysis of error directions, consistency doesn't exist for every patient but by using body-fix showed that the result of stable aspect in spite of changes of everyday's patient position and breathing. Conclusion: Using body-fix for liver cancer patient is considered effectively for tomotherapy. Because deviations between group A and B exist but they were stable and regular.

This study was executed to evaluate the utilization and efficiency of the ceramic biocarrier as the promoter of decomposing on the organic matters for the composting using with pig manure by analyzing of the physico-chemical properties during composting. The treatments of this experiment were consisted of the control(C),microorganism(M), M with natural zeolite(M+Z), M with synthesized zeolite(M+SZ), and M with ceramic biocarrier(M+CZ). The process term of composting was conducted for 30days in the rapidly fermented machine(as pilot system). The results of the physico-chemical properties of the composts were as follows. The changes of temperature during composting was not relative with the microorganism and zeolite materials used in the composts. At all of the treatments were similar to changing of temp. from the initial stage to the final stage. But the added microorganism treatments were higher than control. And the entire pH value of treatments were appeared the same that above temperature result, also the M+CZ and M+SZ treatment among the treatment were higher. At the results of T-C, T-N and C/N ratio, in case of T-C value, the M+CZ treatment was highly more decreased than others. However at the T-N value, there were not the differences from the each treatment. And the C/N ratio was changed according to the changes of T-C and T-N value. Especially, at the M+CZ aud M+SZ treatments were remarkably reduced by about 21.4-23.3 value. In the result of G.I for evaluating of the compost humidity, the M+CZ and M+SZ treatments were close up approximately 110 value compared with the control(G.I value 100). Therefore, the examined ceramic biocarrier amended with compost-promoting-bacteria could be applied to the production of many high quality fertilizers. It is also expected that the results of this researches could be applied to the recycle of the organic wastes based on the experimental results of ceramic biocarrier and compost-promoting-bacteria application.

Submarine cable installation is essentials for grid connection between existing power grid and newly produced electricity which will be from offshore wind farm in Southwest sea area of Korea. Especially, submarine cable route and protection method is designed in order to ensure the economical efficiency, workability and stability of submarine cable installation. On this paper, we will give the basic information about the submarine cable route and protection method of offshore wind farm which will be built in Southwest sea area of Korea. For this, we have a numerical simulation at high and low tide based on the third-generation wave model SWAN(Simulating WAves Nearshore) using the long term wave data from Korea Institute of Ocean Science and Technology(KIOST). The results of the study, year mean Hs is 1.03m, Tz is 4.47s and dominant wave direction is NW and SSW When the incident wave direction is NW(Hs: 7.0 m, Tp: 11.76s), the distribution of shallow water design wave height Hs was calculated about 4.0~5.0m at high tide and 2.0~3.0m at low tide. When the incident wave direction is SSW(Hs: 5.84 m, Tp: 11.15s), the distribution of shallow water design wave height Hs was calculated about 3.5~4.5m at high tide and 1.5~2.5m at low tide. The wave direction on a dominant influence in the section of longitude UTM 249749~251349(about 1.6 km) and UTM 251549~267749(about 16.2 km) in the submarine cable route are each NW and SSW. Prominently, wave focusing phenomenon appears between Wi-do and Hawangdeung-do, in this sea area is showing a relatively high wave hight than the surrounding sea areas.

Nuclear power plants(NPP) are constructed and operated to ensure safety against natural disasters and man-made disasters in all processes including site selection, site survey, design, construction, and operation. This paper will introduce a series of efforts conducted in Korea Hydro and Nuclear Power Co. Ltd., to assure the safety of nuclear power plant against earthquakes and other natural hazards. In particular, the present status of the earthquake, fault, and slope safety monitoring system for nuclear power plants is introduced. A earthquake observatory network for the NPP sites has been built up for nuclear safety and providing adequate seismic design standards for NPP sites by monitoring seismicity in and around NPPs since 1999. The Eupcheon Fault Monitoring System, composed of a strainmeter, seismometer, creepmeter, Global Positioning System, and groundwater meter, was installed to assess the safety of the Wolsung Nuclear Power Plant against earthquakes by monitoring the short- and long-term behavioral characteristics of the Eupcheon fault. Through the analysis of measured data, it was verified that the Eupcheon fault is a relatively stable fault that is not affected by earthquakes occurring around the southeastern part of the Korean peninsula. In addition, it was confirmed that the fault monitoring system could be very useful for seismic safety analysis and earthquake prediction study on the fault. K-SLOPE System for systematic slope monitoring was successfully developed for monitoring of the slope at nuclear power plants. Several kinds of monitoring devices including an inclinometer, tiltmeter, tension-wire, and precipitation gauge were installed on the NPP slope. A macro deformation analysis using terrestrial LiDAR (Light Detection And Ranging) was performed for overall slope deformation evaluation.

저출산과 고령화 이슈는 우리사회의 경제적 문제뿐만 아니라 공적연금의 재정지속가능성 여부와도 맞물려 있다. 실제로 우리나라 모든 공적연금은 사회보험역설(social insurance paradox)이 지속되기 힘든 새로운 도전에 직면하였다. 즉, 재정지속가능성은 제도 내적 연금개혁 혹은 제도 외적 재정지원이 없다면 항시적 수지불균형 상태가 누적될 것으로 예측된다. 이에 정부는 직접 고용과 관련된 공무원연금과 군인연금에 대해서만 연금충당부채를 산출하도록 규정하고 있다. 발생주의회계를 채택한 국제회계기준(종업원급여)을 참조하여 연금충당부채 산출을 위한 연금회계준칙(2011.8.3. 제정; 2011.1.1. 시행) 그리고 '연금회계 평가 및 공시 지침(2011.8.3. 고시 : 이하 편의상 연금회계지침이라 함)'을 신설하였다. 사학연금에 적용성 여부 논의에 앞서, 이들의 산출방법상의 문제점을 먼저 살펴보았다. 첫째, 공적연금은 공통적으로 세대 간 합의에 의해 운영되는 사회계약에 해당하므로 제도의 연속성을 전제로 한다. 하지만 연금회계준칙 및 지침은 제도의 청산을 전제로 현재 가입자(연금 미수령자, 연금 수령자)에 대해서 연금충당부채를 산출하는 폐쇄형측정(closed group valuation)을 채택하고 있다. 즉, 폐쇄형은 제도의 연속성 속성을 반영하고 있지 못하고 있어 기본 전제와 모순된다. 둘째, 공무원연금과 군인연금은 이미 기금 소진(최소한의 유동성기금만 보유함)이 되었고 정부의 보전금에 의해 수지 균형이 유지되는 순수부과방식 체계로 전환되었다. 따라서 연금충당부채는 해당 적립기금의 과소 여부를 판정하는 재정상태 기준 값에 해당하므로 기금소진이 진행된 현 상황에서는 산출의 목적, 필요성을 찾기가 힘들다. 부언하면, 제도 외적 재정지원(보전금)에 의한 수지균형방식이라면 발생주의회계보다는 현금주의회계가 회계의 목적적합성이 높다. 마지막으로 연금충당부채 산출에 있어 가장 민감한 할인율 설정 권한을 기재부장관에게 위임한 내용은 산출의 객관성, 일관성을 확보하기 힘들다고 판단된다. 이를 해소하기 위한 방안으로 본 연구에서는 5년마다 실시하고 있는 장기재정계산에서 예측된 명목 기금투자수익률을 연도별로 적용할 것을 권고하고 있다. 현행 정부회계기준을 사학연금제도에 그대로 적용하기에는 상당한 무리가 있다. 그 이유와 공시방안에 대해 살펴본다. 현재 사학연금은 기금소진 이슈로부터 상당부분 벗어나기 위해 2015년 연금개혁을 단행한 바가 있고 이를 통해 상당기간 부분적립방식 체계가 유지될 것이다. 물론 제도 외적 재정지원은 사학연금법 제53조의7에서 정부지원의 가능성만을 열어 놓은 상태이므로 미래기금소진의 가능성은 상존한다고 볼 수 있다. 먼 미래에는 순수부과방식 체계로 전환될 개연성이 높다. 이러한 재정의 양면성을 본 연구에서는 이중재정방식(dual financing system)이라고 한다. 이러한 속성을 고려하여 연금충당부채(연금채무라는 표현이 적합할 것으로 사료됨)를 산출하고 공시하여야 한다. 그 주요 연구 결과는 다음과 같이 요약된다. 먼저 현행 부분적립방식의 재정상태 검증을 위해 연금채무를 산정할 필요성이 있다. 이를 위해 본 연구에서는 기발생주의(예측단위방식 적용)에 근거한 폐쇄형 측정I(제도 종료를 전제로 현 가입자의 잠재연금채무(IPD) 산출에 초점을 둠) 그리고 미래발생주의(가입연령방식 적용)에 근거한 폐쇄형 측정II(추가적으로 현 가입자의 일정기간 급여 및 기여 발생 허용)을 제안하고 있다. 이를 통해 미적립채무의 규모 그리고 이를 해소하기 위한 상각부담률을 산출할 수 있다. 최종적으로 미래 가입자들까지 포함하고 기금소진 가능성까지 고려하는 개방형측정(open group valuation)을 다루고 있다. 단, 본 연구에서는 공무원연금처럼 기금부족분에 대해서 향후 정부보전금이 있다는 가정 하에 공시 방법을 제시하고 있다. 요약하면, 현행 사학연금제도는 현재와 미래의 재정 양면성을 모두 고려하여 연금채무 및 미적립채무를 공시하여야 한다. 부언하면, 현재 부분적립방식 재정상태를 반영하는 연금채무는 발생주의회계를 적용하고 미래에 도래할 순수부과방식 재정상태는 현금주의회계를 적용할 것을 최종 결론으로 도출하고 있다. 마지막으로 본 연구의 한계는 정부보전금의 가능성에 대한 법률적 해석과 병행하여 책임준비금 범위의 안정적 확대를 전제로 한 공시 논의 그리고 보전금의 책임한도 범위에 따른 공시 논의 등은 다루고 있지 않다는 점이다. 이러한 논의 사항은 향후 연구과제로 두고자 한다.

Purpose : To analyze the anterior stability and functional results after the arthroscopic ACL reconstruction and meniscectomy based on meniscus status at the time of surgery. Materials and Methods : From October 1997 to October 2002, 78 patients (male 64 female 14) were treated by arthroscopic ACL reconstruction and meniscectomy and followed more than 12 months (range, $12\~72$ months, average: 32 months). Average age was 32 years old (range, $18\~57$ years old). We divided the patients into 4 groups; Both menisci was intact (BMI, control group), lateral meniscus removed (LMR), medial meniscus removed (MMR) and both menisci removed (BMR). Anterior passive displacement (objective stability) was estimated using KT-2000 arthrometer under the loading of 15lb,20lb and 30lb and evaluated anterior drawer test, Lachman test, range of motion, thigh circumference. Functional evaluation system of IKDC, OAK and Lysholm knee score was used. Results : Average anterior displacement under the loading of 30lb were 2.47 mm, 2.96 mm, 2.96 mm and 3.57 mm in each group(BMI, LMR, MMR, BMR) and it was statistically significant difference (p<0.05). There is no statistically significant difference in average anterior displacement under the loading of 15lb and 20lb in each group but it has showed decreasing tendency in meniscal removed groups. The mean anterior displacement was within 3 mm in 21 cases, 15 cases, 24 cases and 12 cases (total 72 cases, $94\%$) under the loading of 15lb and 20 cases, 15 cases, 24 cases and 11 cases (total 70 cases, $91\%$) under the loading 20lb of in each group and postoperative knee joint stability has showed increasing tendency (p>0.05). The mean score was 94.5, 93.2, 92.2 and 90.4 points in each group and 71 cases $(91\%)$ were more than excellent or good with a OAK score and fair results were noted 4 cases in both meniscal removed group. There were 65 cases $(83\%)$ with a Lysholm knee score more than excellent or good, and IKDC grading were more than normal or nearly normal in 74 cases $(95\%)$ except 4 cases (2 cases in MMR group and 2 cases in BMR group). Conclusion : Long-term anterior stability and functional results of a successful ACL reconstruction affected by tile status of the menisci at the time of surgery and KT-2000 arthrometer was good for estimation of objective follow up.

In this study, we analyzed the effects of regional hydrologic variability during warm season (June-September) in South Korea due to ENSO (El $Ni{\tilde{n}}o$-Southern Oscillation) pattern changes over the Tropical Pacific Ocean (TPO). We performed composite analysis (CA) and statistical significance test by Student's t-test using observed hydrologic data (such as, precipitation and streamflow) in the 113 sub-watershed areas over the 5-Major River basin, in South Korea. As a result of this study, during the warm-pool (WP) El $Ni{\tilde{n}}o$ year shows a significant increasing tendency than normal years. Particularly, during the cold-tongue (CT) El $Ni{\tilde{n}}o$ decaying years clearly decreasing tendency compared to the normal years was appeared. In addition, the La $Ni{\tilde{n}}a$ years tended to show a slightly increasing tendency and maintain the average year state. In addition, from the result of scatter plot of the percentage anomaly of hydrologic variables during warm season, it is possible to identify the linear increasing tendency. Also the center of the scatter plot shows during the WP El $Ni{\tilde{n}}o$ year (+17.93%, +26.99%), the CT El $Ni{\tilde{n}}a$ year (-8.20%, -15.73%), and the La $Ni{\tilde{n}}a$ year (+8.89%, +15.85%), respectively. This result shows a methodology of the tele-connection based long-range water resources prediction for reducing climate forecasting uncertainty, when occurs the abnormal SSTA (such as, El $Ni{\tilde{n}}o$ and La $Ni{\tilde{n}}a$) phenomenon in the TPO region. Furthermore, it can be a useful data for water managers and end-users to support long-range water-related policy making.
