朴正植 濟州大學校 海洋資源硏究所 1982 해양과환경연구소 연구논문집 Vol.6 No.-
濟州島 近海에서 150톤級 巾着網 漁船이 使用하고 있는 巾着網 漁具의 設計圖와 漁具 明細書를 이용하여 巾着網의 剩余浮力을 計算하여 아래와 같은 結論을 얻었다. 1) 巾着網의 浮力은 沈降力의 1.26倍이다. 2) 巾着網의 잉여부력은 沈降力의 26.3%이고 浮力의 20.8%이다. 3) 綿結綱을 조인후의 浮力은 沈降力의 3.39倍이다. The surplus buoyancy were computed by using a plan and specification of the mackerel purse seine of one boat purse seiner, 150 tons which has operated in the near sea of Jeju Island. The results obtained are as follows : 1. The buoyancy of the purse seine was 1.26 times to the sinking force. 2. The surplus buoyancy of the purse seine was 26.3 percent to the sinking force and 20.8 percent to the buoyancy. 3. After the purse line in the purse seine was pursed. the buoyancy was 3.39 times to the sinking force.

朴正埴 제주대학교 1975 논문집 Vol.7 No.-
This study described on the submarine illumination and the fish finder recordings for the distribution of fish shoal when the mackerel of fishes of the main object in the purse seine of the Jeju was aggregated by attracting lamp, which was investigated from Apr, to Oct, 1975 in the mackerel fishing ground of Jeju near sea. Arrangement of the attracting lamps and a method of submarine illumination's measurement indicated to Fig. 2. 1. Results of a submarine illumination's measurement was equal to Fig. 4A, B 2. In case of fish shoal was aggregated by submarine attracting lamp, distribution of a vertical direction was 10∼25m depth centering lamp and distribution of a horizontal direction was 20∼30m radius. Submarine illumination of this time was 12-1 Lux at vertical direction and 1∼0.2 Lux at horizonted direction. 3. Distance of between the fish shoal and the lamp reduced about 4∼5m in the 30m boundary centering attracting lamp. 4. Alternation of age of the moon for a unit attracting catches show a peak in 6 day and 27 day of age of the moon. 5. Alternation of attracting time was 70% before 2.00 a.m and 28% after 2.00 a.m into 2.00 hour boundary. 6. Catches for the time required of aggregating was 44.2% in 1∼1.5 hour's time and 45.5% in 1.5∼2hour's time.

박정식 한국기독교교육학회 2010 기독교교육논총 Vol.25 No.-
Identity and ethnicity are the critical issues that second-generation Korean American adolescents are facing today. This paper intends to examine the critical issues surrounding identity and ethnicity among second-generation Korean American adolescents as well as draw valuable implications for Korean immigrant church ministry. For this purpose, first, the writer reflects on identity and ethnicity from a biblical point of view. Second, he briefly presents an overview and discussion of a theoretical basis related to the issues of identity, ethnicity, and ethnic identity. Third, he describes the experiences that second-generation Korean American adolescents may share in common in relation to both issues. Second-generation Korean American adolescents tend to have a more difficult time developing a positive sense of identity, compared to their white peers, largely because of the issues surrounding their ethnicity. Finally, the writer draws several implications for second-generation Korean American ministry in light of the discussion. He suggests two important directions, along with some specific ideas and activities, which Korean immigrant churches should consider for ministry to second generation Korean American adolescents. First, Korean immigrant churches need to help their youth appreciate their bicultural identity, encouraging these young people to develop a more integrative identity, while forming their Christian identity. Second, Korean immigrant churches need to help their youth to broaden their understanding of cultural differences and improve their multicultural competency through exercising proper attitudes and utilizing cross-cultural training programs or methods.
