In underwater, such as fish farm and sea, turbidity is increased by water droplets and various suspended, therefore light attenuation occurs depending on the depth also caused by the scattering effect of light float. In this paper, in order to improve the visibility of underwater images obtained from these aquatic environment, we propose a visibility enhancement method using a haze removal method based on dark channel prior and a trained color transform model. In order to train a color transform model, we used underwater pattern images captured from Pohang and Yeosu, and to measure the performance of the proposed method, we carried out experiment of visibility enhancement using underwater images collected from Yeosu, Geomundo and Philippines. The results show that the proposed method can improve the visibility of underwater images of various locations.

The purpose of this study was to investigate clothing attitude according to the self-esteem, body-cathexis and personal-relationship in multicultural families. 198 questionnaires were analyzed by using SPSS program(version 18.0). Self-esteem, body-cathexis, personal-relationship, clothing attitude were examined through 5-point likert scale. 3 factors including clothing interest, social approval and clothing conformity were used as clothing attitude. The results of this study is as follows: First, there were differences in self-esteem, body-cathexis, personal-relationships, clothing attitude in multi-cultural families. Second, self-esteem had positive influences on body-cathexis and personal-relationships in multicultural families. Third, the Chinese were that body-cathexis had positive influences on social approval. The Filipinos were that personal-relationships had positive influences on clothing interest and social approval. The Vietnamese were that personal-relationships had positive influences on clothing interests.

The response to short day treatment in rice plant has been more sensitive along the progress of the growth until 35 days after seeding. The minimum number of short day cycles needed for heading of photoperiod-sensitive rice variety, BPI 76, were 29, 12 and 11 when treatment was started from seeding, 30 days and 35 or more days after seeding respectively.

A nations' cultural heritage embodies its intellectual and spiritual contributions to its civilization of mankind. Cultural properties, whether tangible or intangible, represent both the essence and the basis of national cultures. Both the Philippines and South Korea's cultural heritages have survived various unfortunate chapters of their long histories. This study's purpose is to explore and evaluate the phenomenon of the architecture of Hahoe village in Andong city, Korea and Vigan city of Ilocos Sur, Philippines and to understand and cherish the cultural heritage of both countries. The historic city of Vigan has a unique architecture that blend Ilocano, Filipino, Chinese and Spanish styles in a tropical Asian setting, with a typical Spanish colonial urban layout as specified by the Ley Delas Indias. Hahoe village also represents a masterpiece of human creation and exhibit an important interchange of human values in architecture, monumental arts, town planning and landscape design. Though diverse in milieu, Hahoe village and Vigan city share a common phenomenon which is architecture that is called cultural heritage.

The purpose of this study is to understand a migrant women's married life. The study examined migrant Filipino women's married lives, motives for marriage and migration to Korea, and their married life experiences. The results showed that these women get married to Korean men in pursuit of an economically better life to support their family in the Philippines through marriage migration. As for Filipino women's perceived difficulties in married life, they indicated hardships with redrawing the boundaries of nationality, as well as their husbands' faults or bad habits which are different from what they expected before marriage. Other difficulties mentioned were the peculiar culture of living with parents-in-law, and general difficulties in married life. This study showed that marriage migration results not from external pressure or motives but ultimately from their own decision in a social and cultural context. It was also implicated that Korea's superior position to the Philippines in international economic power has an effect on family relations. The boundaries of nationality are redrawn according to their married life. In addition, it was revealed that the Korean born children of migrant mothers who divorce because of difficulties in married life are in a very poor situation as their national identity depends on their mother's future marriage relations.

The paper presents the Philippine maritime condition, safety systems and navigational aids. It aims to uplift the maritime safety systems and infrastructures by studying the different strata of the industry, thereby emphasizing on the structures, weaknesses and opportunities. It presents the different maritime agencies involved and each responsibilities. Data from PPA demonstrate the statistics of increase in the cargo throughput, passenger, shipcalls and cargo-container handled in the year 2014. It also highlights the insufficiency of different navigational aids, VTMS, MBS and TSS placed in the whole archipelago. It gathers data of maritime accidents in 10-year period, 2006-2015, showing the most occurred accidents, casualties and areas these accidents happened. It includes the weather phenomena which contribute to the maritime movements and accidents incidence. The results show that systems and infrastructures that focus on the lack of improvement in technology and over-lapping functions of different agencies of government require development and upgrading.

석탄을 합성석유로 전환시키는 석탄액화(CTL) 공장은 2차 세계대전시 독일 및 영국에서 가동되어 대량의 연료를 공급한 바 있다. 전후 대형 유전이 발견되어 값싼 석유가 공급되면서 CTL 공장의 운전은 중단되었다. 남아프리카공화국의 Sasol사만이 유일하게 1955년에 CTL공장의 조업을 시작하여 현재 하루 15만배럴의 석탄합성석유를 생산하고 있다. 최근 고유가가 지속되고 석유공급에 대한 불안감 때문에 여러 개의 석탄액화 프로젝트가 진행되고 있다. 중국은 2030년까지 석탄합성석유를 연간 3천만톤(60만배렬/일) 생산할 계획을 수립하였고, 2만배럴/일 규모의 석탄직접액화공장이 2008년 완공될 예정이다. 미국에서도 8개의 CTL 프로젝트가 진행되고 있다. 호주, 필리핀, 인도네시아, 인도 등에서도 석탄액화 프로젝트를 추진하고 있다. 석유를 전량 수입하는 우리나라도 에너지안보 차원에서 CTL에 대한 접근이 필요하다. 본고에서는 한국에너지기술연구원에서 추진되고 있는 석탄 기준 10톤/일급 석탄 합성석유 생산 공정 설계, 설비 시공 현황 및 향후 계획에 대하여 기술하였다.

On November 15, 1994 at 03:17 local time, an earthquake of surface magnitude (M$_{s}$) 7.0 occurred on the northern coast of the Mindoro in Philippine. A major tsunami was generated by this earthquake, extremely large tsunami waves engulfed the Mindoro and the Verde islands. This tsunami caused tremendous casualities and damage. The tsunami propagated to the Luzon island and felt at the Batangas after 10 minutes. The present paper intends to understand the propagation and inundation this tsunami with the aid of numerical computation model and computer graphic aided video animation.n.

A total of 5 pest species wre found ; banana root weevil (BRW) Cosmopolites sordidus Germar (Curculionidae) a wireworm Melonotus sp. (Elateridae), a spider mite teranychid sp. (Tetranychidae), mulberry mealybud Pseudococcus comstocki (Kuwana)(Pseudococcidae), and common cutworm Spodoptera litura (Fabricius)(Noctuidae). Among them, the BRW which attacked the rhizome of banana plant was newly recorded from Korea.
