이 연구는 국내 영화 온라인 부가시장의 활성화에 있어 장애 요인으로 작용하고 있는 유통구조의 문제점을 살펴보고 이에 대응하는 입법 및 정책 현황을 분석해봄으로써 부가시장을 정상화시키기 위한 대안을 제시하는 것을 목적으로 한다. 정보통신기술의 발달로 영화의 유통 창구가 다양화되면서 영화 수익의 극대화와 다양성영화의 유통 기회 확보 등 영화시장이 전체적으로 확대될 수 있는 기회를 맞았음에도 불구하고, 국내 영화산업의 구조는 전적으로 극장 매출에 의존하는 기형적인 형태를 띠고 있다. 전문가 자문회의 및 심층면접 결과, 이는 디지털 영화 콘텐츠사업자들 간의 수익구조의 불투명성으로 영화 부가 판권시장이 제대로 형성되지 못하는 데 기인한 것으로 보인다. 본 연구는 국내 영화산업의 지속가능한 발전을 위하여 온라인 상영관 통합전산망의 구축과 사업자의 가입을 법제화하고, 사업자 간 분쟁조정 시스템의 정비를 통하여 불공정 거래행위를 방지하는 데 정책적 관여가 필요하다는 점을 결론으로 제시한다.

In chlorine dioxide delignification and bleaching the formation of chlorate is undesirable because it does not react with lignin and is harmful to the environment. Chlorate is mainly formed from the in-situ generated hypochlorus acid which is also the main reason for AOX formation. In previous literature scavengers of hypochlorous acid such as sulfamic aicd, DMSO, and hydrogen peroxide have been added to bleaching stages to reduce AOX formation but less attention has been paid to chlorate reduction. This paper thus focuses on the reduction of chlorate content caused by the following additives, sulfamic acid, DMSO, hydrogen peroxide, and oxalic acid. The results show that only sulfamic acid and DMSO reduce chlorate formation under our chlorine dioxide prebleaching conditions. Results by UV spectroscopy and pH adjustment show that scavengers react with hypochlorous acid much faster than with chlorine. Hydrogen peroxide and oxalic acid react with HClO/$Cl_2$much slower than DMSO and sulfamic acid do. The reason for the ineffectiveness of hydrogen peroxide and oxalic acid is ascribed to their slow reaction rates with HClO compared to that of chlorate formation. The fact that only 30-35% of the chlorate can be reduced by sulfamic acid and DMSO when charged in same mole ratio to chlorine dioxide, suggested that the reaction rate of DMSO and sulfamic acid with hypochlorous aicd are of the same magnitude as that of chlorate formation.

The purpose of this study is to investigate the current infrastructure of database on costume cultural heritage. The contents, kinds and accessibility regarding the digital contents of the websites of literature archives, museums and culturecontent.com by Korea Creative Content Agency were analyzed. First, it was evident that the quantity and quality of the database should be improved. The literature archives are mostly comprised of historical documents; however, the quantity of the database regarding the documents that are commonly studied in the field of traditional costume is not satisfactory. On the other hand, the quality of the database depends on the in-depth understanding of the terminology because errors occur when the contents of literature are transferred to an online database. Second, various information is required to meet the needs and interests of the digital environment. Most of the museums provide information on costume cultural heritage through their websites; nevertheless, it is not thorough and only partial. Third, the reliability of information needs to improve. The various contents provided by culturecontent.com lack reliability as it focuses on the entertainment values. To increase reliability, the source and origin of the information about the costume cultural heritage should be provided and the contents should be proofread before they are exposed to the public. Based on these findings, the researchers put forward the following suggestions: the quantity and quality of the databases should be enriched, and that more diverse information is required. Finally, more attention should be paid to increase the reliability of this information. This study will be an asset for the foundation to build solid databases and popularization of the traditional costumes.

Purpose: The purpose of this study was to understand the experiences of interpersonal relationships of head nurses in interacting with others in general hospital settings. Methods: The data were collected by individual in-depth interviews from seven head nurses and were analyzed using qualitative content analysis. Results: Five major categories emerged and they represent a major strategy according to five different groups of interacting people. 'Establishing trust' was identified as the key strategy in dealing with patients and family members. 'Embracing with sisterly love' and 'helping with self-defense' were major strategies for subordinate nurses and physicians, respectively. 'Respecting and recognizing' was the main approach for other professionals such as dietitians and 'emphasizing rules and educating' were a major one for non-professionals. Head nurses paid more attention and made efforts in dealing with their subordinate nurses than with other groups of people, because they felt the most difficulty in their relationship with subordinate nurses. Conclusion: The results of the study showed that head nurses employ unique strategies in interacting with different groups of people to increase the efficiency of communication. This study would help nurse administrators establish an effective program for improving interpersonal relationships of head nurse.

The analysis performed here is aimed to increase the familiarity of hydrologic process especially for the small basins which are densely gaged. Kyung An and Mu Shim river basins are selected as a representative basin according to the criteria which UNESCO has established back in 1964 and being operated under the auspice of Ministry of Construction. The data exerted from these basins is utilized for the determination of characteristics of procipitation and runoff phenomena for the small basin, which is considered as a typical Korean samall watershed. The study found that the areal distribution of preciptation did not show any significant deviation from the point rainfall. Since the area studied is less than 20 km#, the pointrainfall may be safely utilized as a representative value for the area. Also the effect of elevation on the precipitation has a minor significance in the small area where the elevation difference is less than 200m. The methodology developed by Soil Conservation Service for determination of runoff value from precipitation is applied to find the suitability of the method to Korean river basin. The soil cover complex number or runoff curve number was determined by comsidering the type of soil, soil cover, land use and other factors such as antecedent moisture content. The average values of CN for Kyung An and Mushim river basins were found to be 63.9 and 63.1 respectively under AMC II, however, values obtained from soil cover complex were less than those from total precipitation and effective precipitation about 10-30%. It may be worth to note that an attention has to be paid in application of SCS method to Korean river basin by adjusting 10-30% increase to the value obtained from soil cover complex. Finally, the design flood hydrograph was consturcted by employing unit hydrograph technique to the dimensionless mass curve. Also a stepwise multiple regression was performed to find the relationship between runoff and API, evapotranspiration rate, 5 days antecedentprecipitation and daily temperature.

Effect of austenite grain size on starting temperature of ${\gamma}{\rightarrow}{\varepsilon}$ martensitic transformation($M_s$) has been studied in an Fe-18%Mn alloy. Particular attention was paid on the variation of stacking fault energy with austenite grain size, which is considered to be a important factor affecting ${\gamma}{\rightarrow}{\varepsilon}$ martensitic transformation. Austenite grain size was increased in a wide range from $13{\mu}m$ to $185{\mu}m$ with increasing solution treatment temperature from $700^{\circ}C$ to $1100^{\circ}C$. Hardness was decreased with increasing austenite grain size while the volume fraction of ${\varepsilon}$ martensite showed a reverse tendency, which indicates that the hardness is more dependent on austenite grain size than ${\varepsilon}$ martensite content. No significant change was found in $M_s$ temperature when the grain size was larger than about $30{\mu}m$. In case that, the austenite grain size was smaller than about $30{\mu}m$, however, $M_s$ temperature was marlkedly decreased with decreasing austenite grain size. A linear relationship between $M_s$ temperature and the stacking fault formation probability, i.e. the reciprocal of the stacking fault energy was obtained, which suggests that the variation of $M_s$ temperature with austenite grain size is closely related to the change in stacking fault energy.

The effect of storage temperature and time on the contents of metal (Pb, Sn and Fe), vitamin C, color and pH was studied for canned pineapple juice (PJ) and pineapple slice (PS) which were stored for 120 hours at 5 and 2$0^{\circ}C$ and analyzed at 24 hours intervals. The results are as follows; 1. The metal contents of PJ and PS were in the rank of 24<48<72<96<120 hours by storage time at 5 and 2$0^{\circ}C$. These contents were increased to 44.1%/24 hrs of Ph, 18.0%/24 hrs of Sn, 34.6%/24 hrs of Fe but decreased to 6.0%/24 hrs of vitamin C in PJ and PS during 120 hrs. Storage times were correlation to contents of metal and pH but was not correlation to vitamin C contents. These were increased to 37.7%/24 hrs of Pb, 18.8%/24 hrs of Sn, 34.6%/24 hrs of Fe, but decreased to 6.0%/24 hrs of vitamin C. 2. These were increased to 10.6% of Pb, 3.7% of Sn, 11.3% of Fe in PJ and to 33.7% of Pb, 4.8% of Sn, 37.6% of Fe in PS at 2$0^{\circ}C$ than 5$^{\circ}C$ but vitamin C contents were decreased to 8.2% in PJ and 2.7% in PS at 2$0^{\circ}C$ than 5$^{\circ}C$. This fact suggests that more attention be paid in handling canned PJ and PS after opening in order to avoid the decreasing vitamin C and the hazard from Pb, Sn, Fe. 3. Changing factors in Pb, Sn, Fe and vatiamin C content were in the rank of storage temperature$0^{\circ}C$.
