Changes in Oxygen consumption and filtration rates were investigated to understand physiological rhythms for 24 hours of the Manila clam, Ruditapes philippinarum. physiological rhythms in the oxygen consumption and filtration rates at 15$^{\circ}C$ and 25$^{\circ}C$ were showed diurnal tidal rhythms, appearing two peaks for 24 hours: maximum at night-high tide and minimum at day-low tide. No rapid variations in oxygen consumption and filtration rates for 24 hours appeared at two different water temperatures.

Light and electron microscopical characteristics of Perkinsus sp. parasitizing in Manila clam, Ruditapes philippinarum, in Korea were investigated. Trophozoite within the tissue was spherical or ovoid and ranged $2.5-10.5\mu m$ $(mean = 6.2\mu m)$ in diameter. Trophozoite had a nucleus with a prominent nucleolus and a large cytoplasmic vacuole within the cytoplasm. Single trophozoite was phagocytozed by host hemocyte and cluster cells were encapusulated by hemocytes aggregation within the host tissues. Hypnospores incubated in thioglycollate medium (FTM) for 1 to 15 days were also spherical or ovoid and ranged $10-132\mu m$ $(mean\pm S.D.\;:\;44.25\pm 7.91\mu m)$ in diameter. Zoospores were spherical or ovoid, had a nucleus and two flagella. Zoospores contained apical complex, which consisted of conoid, subpellicular microtubules, rhoptries and rectilinear micronemes.

20세기 기술의 발달과 산업화에 따라 세계 각 국에서는 인간이 제어하기 힘든 거대 규모의 도시가 계속하여 형성되고 있다. 전 세계 대도시들 중 대기오염도가 심한 도시의 하나에 속하는 필리핀의 Metro-Manila는 1975년 11월 마닐라를 중심으로 총 13개 소도시와 4개의 자치지구가 통합되어 구성되었으며, 면적은 서울(605.5$\textrm{km}^2$)과 비슷한 636.0$\textrm{km}^2$이다. 인구 밀도는 약 15,617명/$\textrm{km}^2$로 서울(17,046명/$\textrm{km}^2$)보다는 다소 낮고, 전체 인구수는 서울과 유사한 약 1천만 명 정도이다.

Parasitic organisms in the Manila clam Ruditapes philippinarium were investigated from May 2001 to April 2002 from a population of clam inhabiting intertidal zone of Shi-Heung Ri on the west coast of Jeju. Perkinsus atlanticus and Cecaria tapidis were the two main parasites that occurred firequently among the clams. Occurrence of P atlanticus varied seasonally with lowest level in late September 2001 (6.0%) and highest infection level in March 2002 (86.0%). (omitted)

Hemocytes in marine bivalves play important immunological roles in discrimination, opsonization and phagocytosis of foreign materials as a defense mechanism. In this study we report the flow cytometric implications to investigate the immune parameters such as the compositional and the functional characteristics of hemocytes isolated from the Manila clams, Ruditapes philippinarum. Heterogeneity of the hemocytic cell population was determined by the forward scatter (FSC) and side scatter (SSC) cytometric profile which showed three populations: granulocytes, hyalinocytes and small agranular cells. In addition, phagocytosis rate was measured after adding fluorescent-labeled particles. The data were initially analysed for two-parameters: FSC and SSC, then the fluorescent (FL 1) frequency distribution histogram of the hemocyte population was subsequently obtained.

The existence of Internet revolutionized the computer and communications world. With the rising demand for accessing the Internet, the mobile technology has incorporated the use of Internet in mobile phones. Wireless Application Protocol (WAP) has combined two of the widest utilized technology today: mobile phones and Internet. This study aims to assess the existing WAP pages offered by the top service providers in the Philippines through usability testing experiments. The paper also aims to identify existing problems in WAP interface by focusing on the errors committed by the users. From the usability study, it was found out that common usability problems are wrong selection of links, unclear grouping of categories, wrong feedback, and redundant links. The type of service provider used is significant in determining the performance of users while experience in accessing WAP is insignificant.

The Manila clam, Ruditapes philippinaMm (Pelecypoda: Veneridae) is present along the coasts of Korea, China and Japan. In particular, Recently, due to reclamation of tidal areas along the west coast, marine pollution, and reckless overharvesting of this clam, its standing stock has reduced for a decade. Therefore, it is necessary to manage the population of the clam with a proper fishing regime that will maintain an optimal population size in aqua farm. (omitted)

In this study, the types and characteristics of rice cake, cookies were investicated in the rice grown area-Korea, Japan (Tokyo, Osaka), China (Hongkong), Thai (Bangkok, ChiengMai), Indonesia (Bali, Jakarta), and Philippine (Manila). 1. Rice cakes and cookies were made from rice powder and rice granule. Specially, there were two kinds of basic rice powder one was rice powder in dry and the other was rice juice grinded with water on the millstone. Rice juices were named in China, MeeChang, in Manila, Galapong, in Bangkok, rice powder. 2. The kinds and numbers of steamed rice cakes were the most available in all investicated area. In Hongkong, Bangkok, ChiengMai, and Manila, beatened or kneaded rice cakes could not be seen almost. Only in Hongkong and Bangkok, fried rice cakes were available, while in Japan, boiled rice cakes were not seen almost, and also baked rice cakes were not seen in Korea, Hongkong, Bali, Jakarta. 3. In the east-south Asian area, except rice and glutinous rice, coconut and palm fruits and banana were using in recipies of rice cakes and cookies. They gave soft and tender mouth feeling, white color, and good emulsifying status. 4. The kinds and numbers of rice cookies were the most available in Bangkok, but in Bali and Jakarta, the least. The cookies of Japan had similar texture and shape to rice cake while most of cookies in Hongkong were fried in oils. In Korea, the kinds and numbers of rice cookies were less than those of rice cakes.
