The subject of port efficiency is one of the important issues facing port authorities and policy makers today. A number of studies have been undertaken which compare ports in terms of their efficiency. But any port comparison can only be valid and meaningful if a port’s efficiency is compared with a similar port. The main objective of this paper is to introduce a systematic approach to identifying similar ports based on the technique of principal component analysis and cluster analysis. And it seeks to identify the most important factors underlying the port classification. Lack of awareness of which factors differentiate ports has resulted in an unnecessary collection of data which are of limited use in port classification. This paper has identified five groupings of similar ports within which port comparision can be justifiably made. This approach can be used for any future port comparision.

The comparision of sunshine duration meter was carried out on the roof of Korea Meteorological Research Institude by comparing Pyrheliometer(Eppley NIP model) to sunshine duration meter(Reflection type) during from Nov. 8, 1989 to Feb. 19, 1990. In the observation Period, daily mean sunshine duration time difference of Jordan sunshine duration meter was recorded 0.47hour and Reflect sunshine duration meter was recorded 0.39hour. More than one hour time difference was observed 15 cases by Jordan sunshine duration meter and 11 cases by Reflect sunshine duration meter.

This paper presents a mechanical design of the deepwater pipeline wall thickness using the recent design rules. Characteristics and limitations of the new codes were identified through a case study design in the Gulf of Mexico. In addition to the ASME, API, and DVD codes, the code of federal regulations (CFR) was also utilized in the design. It was found that conservatism still exists within the collapse prediction for water depth greater than 1500 m. Comparision of the results from DNV and API codes were presented.

In this Article the writer introduces the origin and preparation of "the UNIDROIT Principles of International Commercial Contracts". In May 1994 the Governing Council of the UNIDROIT gave its formal imprimatur to the UNIDROIT Principles and recommended their widest possible distribution in practice. After brief discussion of the establishment procedure of the UNIDROIT Principles the writer discusses the legal nature of the Principles as an international restatement of contract law. The UNIDROIT Principles has more flexibility than international convention. But it has deficit in the sense of legal stability. Also the scope of application of the Principles was discussed. It can be applied only to the international commercial contracts. It includes two basic principles in it's application, i. e. "commercial contracts" and "international contracts". For the rest of the Article the writer concentrates on the contents of the Principles and the basic ideas underlying the Principles from the point of view of the comparision between the UNIDROIT Principles and "the UN Convention on the International Sale of Goods" (CISG). The UNIDROIT Principles are only restatements and the CISG is an international convention. The application of the CISG is obligatory due to its nature as an international convention. In the contrary the possibility of the application of the UNIDROIT Principles is more flexible. The UNIDROIT Principles is a more comprehensive instrument than CISG. Therefore it can be applied to all kinds of international commercial contracts. In the contrary the CISG can be applied only to international sales contract. Since CISG only deals with contracts for the sale of goods, and the scope of the UNIDROIT Principles is much wider, no overlap can occur where contracts other than sales contracts are concerned. Rather the UNIDROIT Principles can supplement the CISG and the CISG also can be criteria in interpreting the UNIDROIT Principles. As the conclusion the writer summarizes the meanings of the UNIDROIT Principles and presupposed the futur perspectives of the Principles.

Through the this paper, a conclusion could be derived from CISG PICC MISC made by UNIDROIT, UNCITRAL, ICC of representative system making out a draft for uniform law, convention, trade usages. (1) In short, like most int'l sales rules applicable to commercial contracts, these rules play a supporting role, supplying answers to problems arising from transaction between the parties. (2) Though every one has in its own way a special feature, use of MISC made on the basis of actual facts which the parties are faced with their daily transactions, CISG and Incoterms being now in force, is desirable. (3) In case of use of MISC similar to a system of Incoterms, as PICC, it is necessary for MISC to set forth definitions about important terminology which is possible to give concerned parties confusion. (4) In a sense, PICC has a character complementing problems which CISG can not solve, therefore, if int'l agreement is given, it is desirable to adopt revised PICC adding specials conditions (A) of MISC as appendix of PICC such as Llouyd's Form in an appendix to MIA, as int'l convention.

Because of varied functions and characteristics, water soluble polymers have lone attracted much intrest in both academic and industrial fields, especially now in pollution problems such as wastewater treatment through ployrneric flocculants. In this regard, the main objective of this study is to synthesize polymeric floccuants containning hydrophobic group in presence of the potassium persulfate/sodium thiosulfate redox system and to estimate their flocculating ability on the kaolin suspension. In order to test the flocculating power of flocculant prepared on the kaolin suspension system, turbidity of the supernatant liquid, residence time, filtration rate of flocculated samples, have additionally been measured from the flocculation experiments and analysed In comparision with the theoretical background.

This study focused on situational simularity of psychedelic expressed in the mid-1960s with culture including costume in the end of 20th century. So this study is composed of psychedelic concept and the comparision of temporal background and general characteristics of psychedelia in the 1960s and 1990s and relationship with Art-Nouveau which has originated psychedelia and psycheelic image including mysticism play illusionism and narcissism. The New psychedelic revival of the early 1980s came at a time when as in the mid-1960s the world's attentions were firmly focused on British youth. The same could be said of the mid-1990s when 'BriPop' once again has international appeal and the result has been a kind of New New Psychedelic revival with all manner of British youth styles from the 1960s blended together. The swirling patterns hallucinogenic colors and space-aged designs of the psychedelics have become a symbolic representation of cocktail of youth sex and optimism

Three-day dietary records data from 237 college students(male 65, female 172) were used as the basis to estimate total dietary fiber(DF) intake of Korean adults & to investigate the major food sources of fiber. Mean daily DF intake of the subjects was 15.2$\pm$3.7g range being 7.5-34g When related to energy intake women consume more DF(7.7$\pm$1.5/1000kcal) than men(6.8$\pm$1.7g/1000kcal) Mean daily crude fiber(CF) intake of the subjects was 6.2$\pm$2.4g The mean DF:CF ratio for the subjects was 2.5$\pm$0.5 indicating that DF intake is 2-3 times of CF intakes The intakes of the two measures of fiber were highly correlated(r=0.791) The major food sources for DF in Korean are vegetables cereals and fruits and 14.3% respectively In comparision with limited international data on the DF intake by adults DF intake by the subjects was similar to those of developed countries. Present study indicates that DF intakes of the subjects are considerably lower than recommended level and they need to consume more DF than the present level.
