As the education of maritime college has a characteristics of seafaring professional institutions, the potential benefit following from the employment of seafarers would put substantial impact on it. The socio-economic position of seafaring occupations has been deteriorated considerably with changes of ship's auto-mation, specialisation and low cost operation management of shipping companies through severe internatio-nal competitions. The quality and number of applicants for the maritime college has declined and most students have no hopes for the study of seafaring subjects which followed bewildering in their college days. However, the demands for seafarers are fairly large from the viewpoint of national maritime industry. The maritime institutions should not only meet these demands but also revitalise students by reforming the educational contents. The contents should be influenced by the social approach to educational needs in particular maritime shore-oriented subjects. The maritime education is no more restricted to the sea, it covers the land based world of the maritime industry as well. The new contents will lead the maritime educated students to the shore-based occupa-tions after finishing their seafaring if they want to. This may not only make ways to the maritime educa-tion fruitable, but also the students have a zeal and hope for the subjects taught.

In-process diagnosis of the cutting state is essential for the automation of manufacturing systems. Especially when the cutting process becomes unstable it induces self-exited vibrations a frequent case of poor tool life rough surface finish damage to the workpiece and the machine tool itself and excessive down time. To ensure that the cutting process main-tains stable it is highly desirable to have the capability of real-time. To ensure that the cutting process main-tains stable it is highly desirable to have the capability of real-time monitoring and controlling chatter. This paper describes the detection method of chatter vibration using cutting force in turning process. In order to detect a chatter vibra-tion the dynamic fluctuation of radial force is analyzed since this components is sensitive to the chatter. The envelope sig-nal of radial force has been calculated by the use of FIR Hilbert transformer and it was useful to classify the chatter signal from the dynamically unstable circumstances. It was found that the mode and the mode width were closely correlated with the chatter amplitude was well. Finally back propagation(BP) neural network have been applied to the pattern recognition for the classification of chatter signal in various cutting conditions. The validity of this systed was confirmed by the experiments under the various cutting conditions.

A radiotracer technique has been developed to monitor the rotational movement of two piston rings in one cylinder during engine operation. The rings were labeled with two different kinds of radioisotopes, i.e. $^{60}$ Co and $^{192}$ Ir, for identification of the top ring from the second ring. The radiotracers were implanted in a small hole bored on the inner side of each piston ring. The rings were installed in a single cylinder hydrogen engine and three Nal scintillation detectors were mounted around the engine block to measure the gamma radiation. The angle of ring-gap orientation was determined from the radiation counts measured with the three detectors during engine operation. Two windows (upper window for $^{60}$ Co and lower window for $^{192}$ Ir) were set on each ratemeter to count radiation from the two isotopes separately. Procedure to convert the radiation counts to the position of the ring gap was established. With the software programmed with MS-Visualbasic, radiation counts were compared with the reference responses that were measured at angular intervals of 10$^{\circ}$for each piston ring in advance of the experiment. The result was used for the evaluation of the relationship between the orientation of ring-gaps and oil consumption. It was found that an increase in the oil consumption rate of a specific operation condition was closely related to the relative phase angle of the two piston rings.

Purpose: This study was aimed to clarify the concept of ego-resiliency in the context of nursing and to propose a definition of ego-resiliency. Methods: Rodgers' evolutionary approach to concept analysis was used to identify common attributes, antecedents, and consequences of the term ego-resiliency. A literature search of the RISS, NDSL, NAL, CINAHL, PubMed, MEDLINE, PsycINFO, and Scopus databases from 1980 to 2014 was conducted, using the key words of ego-resiliency, ego-resilience, and ego-resilient. Thirty-four relevant articles and one book were finally selected and throughly reviewed. Results: The results of the concept analysis concluded that ego-resiliency was a individualized, integrated, and coping resource and capacity leading personal adaptive capacity including physical, psychological, social well being in various adversity and challenge of life. Conclusion: The findings of this study warranted nursing research on a development of nursing intervention related with ego-resiliency as a pivotal personal characteristic. By doing so, better understanding of human and health within the context of nursing could be achieved.

Underweight patients were studied with respect to changes in their nutritional status before and after administration of nutritional beverage. Patients with renal hepatic or endocrine disease gastrectomy malabsorption and weight gain over past 6 months were excluded. Ten patients were participated as controls and were allowed to eat ad libitu, Twenty patients were served as case and were administered in addition to their usual diet 400ml of nutritio-nal beverage(Greenbia) high in calorie and protein for 8 weeks. In the beginning of the study most underweight patients showed depressed nutritional status in terms of calorie intake quality of protein intake and the levels of visceral protein status and serum micronut-rients. The controls consumed less amounts of calories proteins vitamins and minerals while those given the nutritional beverage exceeded their estimated energy requirement(105%) and consumed a mean of 96g protein per day. Those given nutritional beverage for 8 weeks showed significant increase in body weight(3%) hemoglobin(3.2%) hematocrit(5.4%) serum transferrin(19.4%) iron(30.1%) and zinc(20.9%) In the controls however significant improvement was not observed in any parameters compared with initial values. significant improvement was not observed in any parameters compared with initial values. This study suggests that patients with underweight can show mild nutritional deprivation nutritional support can improve their unbalanced status and prevent severe malnutrition.

This study was conducted to investigate the contemporary dietary life of residence in Kyunggi province. People living in Kimpo, Yoju districts(farm villages), Kapyung districts (mountain villages) and Hwasung districts (fishing villages) were selected for this research as subjects from August S to 19,1997. The results of the survey are summarized as follows: 1. Cooked rice was a staple food. However nuddles and soojaebees(soup with dough flakes) was taken as lunch or snacks but Juk(rice guel) or Dduk(rice cake) was not treated as a meal. 2. Dishes were consisted with soup or chigae, kimchi and namul(seasoned vegetables), and fishes, meats, salted sea foods, dried fishes, jangacchi(dried seasoning radish) were also taken by sometimes. 3. Soy sauce, bean paste, red pepper bean paste were made by every home even if they were very busy. 4. Festival days such as New Year's Day, daeborum(the 15th day of January), chusok(mid-autumn festival), and kosaa(October ceremony) and dongee(one of 24 seasons by lunar calendar) are skipped oftenly and slowly forgotten by people. They do not celebrate Samgin-nal(the third day of March), Buddha's birthday(the 8th day of April by lunar calendar), danoh(the 5th day of May), yoodoo(the 15th day of June), chilsok(the 7th day of July), Jungyang(the 9th day of September) and the last day of the year either 5. Due to improved kitchen system, we couldn't see the old kitchen devices.

In this paper, we propose a novel mixing algorithm for multiple video streams, which can guarantee low complexity and low end-to-end delay. In the propose algorithm, we change the syntax bitstream in the compressed domain. And we mix the H.264/AVC video streams by coded slice unit. The syntax bitstream for a mixing changes according to the arrangement of videos streams in which it organizes the mixing screen layout. Experimental results show more than 4 video streams could be mixed at high speed. Moreover, it could display in the player which it supports the standard H.264/AVC without the picture quality loss.
