The Korean frozen pork loins in vacuum packaged were obtained from three different Korean export companies and investigated for pH, proximate composition, cooking loss, physico-chemical and sensory characteristics. The frozen pork loins were stored at -20$^{\circ}C$ for 40 days. The results were as follows: The protein contents were relatively higher in the samples from the company II and the ash contents were relatively higher in the samples from the company I than those from the other companies. The samples from the company Ⅱ had highest pH and water-holding capacity, and cooking loss and shear force were lowest in the company II. The total plate counts and coliform bacteria for loins from 3 companies were in the range of 3.04${\sim}$3.75 log cfu/$cm^2$ or g and 0.37${\sim}$1.32 log cfu/$cm^2$ or g in average, respectively. The TBARS values were 0.35${\sim}$0.38 mg malonaldehyde/kg sample. There were no significant differences in sensory characteristics for raw and cooked loins from all companies.

The purpose of this study was to investigate the effect of somatosensory input on the gait ability and equilibrium sensory of elderly women. The subjects who participated in this study were 31 elderly women with a mean age of 75 years or older who no using a walking stick and had no abnormality in otolaryngology. The control group consisted of 30 elderly women who did not exercise regularly more than twice a week. Dependent variables consisted of 2.44m timed up and go test, 10m usual gait, 10m fast gait and 6minute gait. The equilibrium sensory test was performed using EquiTest (NeuroCom, USA). The results of the study on gait ability were not statistically significant for 2.44m timed up and go test, and 10m usual gait. However, 10m fast gait (P<.001) and 6min gait (P<.05) showed significant differences. According to the results of the study on equilibrium sensory ability, there was no significant difference between Condition 1 and Condition 5 however Condition 2 (P<.01), Condition 3 (P<.01), Condition 4(P<.01) and Condition 6 (P<.05) showed statistically significant differences. In conclusion, walking stick have beneficial effects on walking and equilibrium sensation, and elderly women need to actively use walking stick when going out and walking.

This study examined the effects of work values and the career decision level on the major commitment of the university students majoring in social welfare. For this purpose, a survey of 351 undergraduate students majoring in social welfare at 4 universities located in Kangwon-do was conducted and the data were analyzed. The work values consisted of intrinsic values and extrinsic values. The career decision level was measured by the career decision scale (CDS) and the major commitment was measured by the flow state scale (FSS). The research findings are as follows. First, the career decision level (3.43) and major commitment (3.58) of the university students majoring in social welfare were slightly higher than the mid-point on the 5 point Likert scale. In addition, the intrinsic work value (4.05) were higher than the extrinsic work value (3.34). Second, the intrinsic work values and career decision level were positively correlated with the major commitment. Third, the extrinsic work value had a negative effect on the major commitment (${\beta}=-.34$, p<.001); however, the intrinsic work value (${\beta}=.31$, p<.001) and career decision level (${\beta}=.18$, p<.001) had a positive effects on the major commitment. This paper also discusses the theoretical and practical implications for university student's work values, career decision level, and major commitment based on the research findings.

There is no safety evaluation index with marine accidents and information of ship's safety management result for good grasp of safety management level of shipping company and effective monitoring. In this paper, we proposed a SMEI(Safety Management Evaluation Index) for evaluation of shipping companies. The SMEI is consist of MAR(marine accidents ratio), SSMR(ship safety management ratio) and SAP(safety advantage point) through brainstorming of the expert group and AHP(analysis hierarchy process)in previous study. And weights of SMEI are calculated using experts's opinions through the Delphi method. We also verified the validity of proposed SMEI to 119 Korean shipping companies with 916 ocean-going ships of Korean flag, which grouped three part (small, mid and big) by number of ship and gross tonnage. And we found out 19 shipping companies, 8 companies in group1 & group2 respectively and 3 companies in group 3, with score below 1.0 by SMEI. In these companies, there are no marine accidents in recent 3 years and appeared low frequency remarkably in the detention and mojor non-conformity by data analysis.

This study was investigated to effect of tongue strength and accuracy training (TSAT) on tongue strength, swallowing function, quality of life in chronic stroke patients with dysphagia. Eighteen chronic stroke patients with dysphagia participated in this study, and were allocated randomly to experimental(n=9) and control group(n=9). both group conducted to traditional dysphagia therapy, and experimental group was carried out additionally TSAT. TSAT performed using Iowa Oral Performance Instrument(IOPI), and was set up to 50%, 75%, 100% of maximum isometric tongue strength. Two groups received the treatment for five per weeks, eight weeks. Outcome measurements performed that Maximum Isometric Strength(MIS) was assessed by using IOPI for measure the tongue strength, and Swallowing Function Test(SFT) was used to assess the swallowing function. Swallowing-Quality of Life(SWAL-QOL) was used to evaluate quality of life related to swallow. In results of study, experimental group in comparison of change score between two group significantly improve than control group in anterior and posterior MIS, and SFT. SWAL-QOL was not significantly difference in both group. Based on thin study results, TSAT may be a effective intervention to improve on tongue strength, and swallowing function in chronic stroke patients with dysphagia.

It is an essential element for the establishment of image processing related systems to find the exact contour from the image of an arbitrary object. In particular, if a vision system is established to inspect the products in the automated production process, it is very important to detect the contours for standardized shapes such lines and curves. In this paper, we propose a prototype adaptive dynamic contour model, p-Snake with improved contour extraction algorithms by adding the prototype energy. The proposed method is to find the initial contour by applying the existing Snake algorithm after Sobel operation is performed for prototype analysis. Next, the final contour of the object is detected by analyzing prototypes such as lines and circles, defining prototype energy and using it as an additional energy item in the existing Snake function on the basis of information on initial contour. We performed experiments on 340 images obtained by using an environment that duplicated the background of an industrial site. It was found that even if objects are not clearly distinguished from the background due to noise and lighting or the edges being insufficiently visible in the images, the contour can be extracted. In addition, in the case of similarity which is the measure representing how much it matches the prototype, the prototype similarity of contour extracted from the proposed p-ACM is superior to that of ACM by 9.85%.

The purpose of this study is to examine the interpersonal competence of science-gifted students in groups of people with different characteristics. We examined the interpersonal competence and characteristics of students in school and in science-gifted education institute. The subjects of this study were 72 students in a university-based science-gifted education institute. We used a mixed method of both qualitative and quantitative research. The questionnaires were used for quantitative research and the narrative contents and interviews were analyzed for qualitative research. We compared their competence in school with those of gifted education institute students through questionnaire, narrative contents, and interviews. The interpersonal competence questionnaire consisted of 46 questions and their own descriptions about interpersonal experiences in school and in science-gifted education institute. In an interview, they explained their answers on the questionnaires with more details. As a result, generally, the science-gifted students evaluated their interpersonal competence higher in school than those in gifted education institute. They showed different interpersonal characteristics in schools and in science-gifted education institutes. This implies implications for the social meaning of the science-gifted education institutes.

The purpose of this study is to inquire into the effects of teaching methods in the class on the conceptual change of atmospheric pressure for middle school students. After analyzing the concept of atmospheric pressure in the middle school science textbooks on the present 7th Curriculum, classes were performed adopting classified Method A and Method 3. For Method A, the textbook is used to explain the concept in the view of weight. For Method B, the textbook is used to approach the concept in the views of molecular movement as well as of weight. This study consists of four classes in the third grade students of middle school in Busan, where they were divided into the Method A group and the Method B group. These study was carried out with pre-post on each of these classes on the learning achievement and on the conceptual change of atmospheric pressure. The results of this study were as follows: First, the effect on the learning achievement was displayed the average score of the Method B was showing a meaningful difference comparing to the Method A. Second, the effect on the conceptual change measured by verifying the score for the difference among the averages for each sub-scale three out of four conceptual factors,'the direction of atmospheric influence and the reason','the principle of atmospheric action' and 'the atmospheric changes by the temperature rise on the surface of the earth and the reason', showed meaningful improvement. But, the one left factor,'the distribution of atmospheric pressure by altitudes and the reason', displayed no meaningful difference. Third, The concept of atmospheric pressure is better defined as the pressure created by the movement of air particles, in the view of kinetic theory of gas, rather than explained by the notion of the weight of air.

Objectives : The purpose of this study is to investigate whether the ability of facial affect perception is associated with schizotypal personality traits in healthy normal controls. Methods : 241 normal subjects were recruited in this study. The age range of all subjects was from 19 to 63 years. The schizotypal personality questionnaire(SPQ) and facial affect identification test(FAIT), which were developed and standardized in Korea, were applied. Subjects from high 1 standard deviation(H group, N=40) and low 1 standard deviation(L group, N=26) on SPQ score were compared. Results : We found that the H group showed significantly reduced ability on the correctness of sadness and neutral compared with the L group. But, no significant association between SPQ and intensity or reaction point was observed in all subjects. Conclusion : This study suggests the individuals with high schizotypal personality trait have impairments on the facial affect identification. Also, these findings may provide the reasonable explanation of social cognition deficit of schizotypal personality disorder.
