  • Visual monitoring is hard to apply on fish because they are living in a water system. To overcome this problem, acoustic telemetry, which is effective for underwater monitoring, is often used for studying fish behaviors, such as movement distance, route and patterns. In this study, in order to monitor the movement pattern of Squaliobarbus curriculus (family Cyprinidae), we used acoustic telemetry and identified the home range and movement distances. A total of nine individuals were released at two different locations: one is at the estuary barrage (Sc1~3) and the other is at the lower part of Baekjae Weir (Sc4~9), located in Geum River. Approximately, a 70 km section from the estuary barrage was investigated. Fish, which were released at the estuary barrage, utilized up to 12.7 km upstream as home range from the release site. At the lower part of Baekjae Weir, most of the fish moved and stayed within a 7.2 km downstream area, except for Sc6, which moved 53.4 km (linear maximum distance from release site) downstream from the release site. Relatively small sized fish (Sc7~9) did not show any movement. Accumulated movement distance significantly correlated with the standard length of S. curriculus ($r_s$=0.715, p=0.03). Moreover, the standard length of moving fish was significantly larger than that of not moving fish (Mann-Whitney U test, p=0.024). Therefore, the movement distance of S. curriculus has been correlated with fish size; movement distance was increased with the standard fish length. Although the sample size of monitored fish was small, various meaningful data were collected by acoustic telemetry. Consequently, this technique could be a method available for effectively monitoring the behavior and ecology of native Korean and endemic species.

  • The current study was conducted to determine the effect of suspension method on satisfaction level of Korean consumers and objective meat quality traits in Hanwoo longissimus dorsi(LD), triceps brachii(TB) and semimembranosus(SM) muscles. Eighteen Hanwoo steers were slaughtered and alternative sides were hung either by pelvic bone(TS) or Achilles tendon(Al). Sensory characteristics, WB-shear force, sarcomere length, water-holding capacity, saroomere length and cooking loss were determined after a 7-d chiller ageing. Higher carcass quality grade received significantly(p < 0.05) greater eating quality for LD, but the grade did not affect eating quality for both TB and SM. TS did not influence objective and subjective meat quality for TB, but that significantly(P < 0.05) improved eating quality for LD and SM. The most noticeable result was that when SM was tenderstretehed, eating quality was equivalent to that of nonna1ly hung LD. In relationship between objective and subjective meat quality assessments, eating qualty for LD had a significant(P < 0.05) relationship with intramuscular fat content, while that for SM was greatly(P < 0.05) related to saroomere length. The current study indicated that pelvic hanging was an effective way to improve eating quality both LD and SM, and carcass quality grades did not greatly reflect eating quality of SM and TB. The data also implied that instnunental measurements poorly estimated the satisfaction level of Korean conswners.

  • The purpose of this study was to find the status of health examination and health management of industrial companies located in Taegu and Kyung book areas. It will provide basic information for the provision of effective health management of industrial workers. 49 companies were selected as a study sample group, and data was collected by using a structured Questionnaire which was developed by the members of the Community Health Nursing Academy of Korean Nursing. The health managers of the companies filled out the Questionnaire. The data was gathered from Dec 20, 1992 to Jan 20. The results of the study was as follows : 1. The Study sample showed 85.7% manufacturing companies having 300 or more workers. 2. All the companies had health managers, and companies which had 1,000 or more workers had industrial physicians and nurses. Only 12.2% of the industrial physicians were full time employees, and almost all industrial nurses were full time employees. Except for industrial physicians and nurses, the proportion of hygienists (6.1%), nurses aids (4.1%), and environmental engineers (22.4%) with full time employment statuss was very low. The mean age of industrial physicians was 49.2 while that of industrial nurses was 27.2. The length of work experiences currently ranges for 1 to 3 years for all health workers: physicians, nurses, hygienists, and environmental engineers. 3. Health examination and follow up care 94.31% took general health examinations. Of those, the proportion of the workers, who were determined as C grade(in need of close examination) was 43.86%. The proportion of the workers who were determined as D grade was 22.19%. 13.28% of the workers evaluated at the D grade were taken as a gauge for temporary leave from work. While 8.7% and .09% of them were taken as gauge for a change in job, and or shortening work hours respectively. The proportion of workers who must have taken special examination was 65.04% and of those the proportion of the workers who actually took, the examination was 98.55%. 75% of the workers who were recommended for follow up care were given follow up care. The special examinations were done the most frequently to detect the effects of physical agents (59.2%). Direct notice to individual workers was used the most frequently as a method of notification after a special examination (61.2%). The length of time taken to receive the result of a special examination was less than 1 month (38.9%) and 36.7% had taken up to two months (36.7%.). Most results of special examination were obtained within 2 months. The referral rate of consulting special examination by health managers was estimated at 95.9%. 4. 89.8% of the companies had. their own company dispensaries and 75.5% of those. had separate dispensaries. 32.7% of the companies designated local clinics for health management of workers. Industrial nurses performed health examination the most frequently(1.4 points). Health appraisal for work places were. done the least(0.83 points).

  • Recent years, the use of multimedia information is rapidly increasing, and the video media is the most rising one than any others, and this field Integrates all the media into a single data stream. Though the availability of digital video is raised largely, it is very difficult for users to make the effective video access, due to its length and unstructured video format. Thus, the minimal interaction of users and the explicit definition of video structure is a key requirement in the lately developing image and video management systems. This paper defines the terms and hierarchical video structure, and presents the system, which construct the clustering-based video hierarchy, which facilitate users by browsing the summary and do a random access to the video content. Instead of using a single feature and domain-specific thresholds, we use multiple features that have complementary relationship for each other and clustering-based methods that use normalization so as to interact with users minimally. The stage of shot boundary detection extracts multiple features, performs the adaptive filtering process for each features to enhance the performance by eliminating the false factors, and does k-means clustering with two classes. The shot list of a result after the proposed procedure is represented as the video hierarchy by the intelligent unsupervised clustering technique. We experimented the static and the dynamic movie videos that represent characteristics of various video types. In the result of shot boundary detection, we had almost more than 95% good performance, and had also rood result in the video hierarchy.

  • Purpose: To establish basic data for effective management and quality improvement on clinical practice by investigating the clinical practice satisfaction of ophthalmic optics students and optical shop owners. Methods: A survey was administered for 281 students with experience in clinical practices and 105 optical shop owners regarding satisfaction of ophthalmic optics students and optical shops. And a statistical analysis was performed on the survey results. Results: 92.% (97 shops) of optical shop owners responded that clinical practice was necessary and there was a significant difference (p=0.004) according to gender. 4 weeks was the preferred length of practice period (53.3%) and there was a significant difference according to the size of the optical shops (p=0.000). Clinical practice satisfaction of students was 3.50 ${\pm}$ 0.68 and satisfaction for clinical practice program, clinical practice time and clinical practice shop (3.74 ${\pm}$ 0.80) were the highest and there was a significant difference according to the age of the students (p<0.05). Clinical practice satisfaction for optical shops was 4.08 ${\pm}$ 0.64 which is higher than student satisfaction. Satisfaction for clinical practice program was (4.17 ${\pm}$ 0.54) was the highest. Conclusions: To maximize the effects of clinical practice, a clinical practice program reflecting the satisfaction of students and optical shops is required and further research and attention are required.

  • Data on the first lactation performance traits of $F_1$, $F_2$ and $F_3$ crosses covering the period from 1972 to 1995 of a total of 803 dairy cows of three genetic grades maintained at Livestock Production Research Farm, Indian Veterinary Research Institute, Izatnagar were analysed. Three genetic grades were 1/2 Friesian + 1/2 Hariana (FH), 1/2 Friesian + 1/4 Brown Swiss and 1/4 Hariana (FBH) and 1/2 Friesian+ 1/4 Jersey + 1/4 Hariana (FJH). Age at first calving increased by 7% and 8% in $F_2$ and $F_3$, respectively, over the $F_1$ in FH. The reduction in age at first calving at $F_2$ and $F_3$ levels by 2-7% over the $F_1$ was observed in FBH and FJH. The lactation milk yield of $F_1$, $F_2$ and $F_3$ crosses was $1,943{\pm}100.3$, $2202{\pm}120.5$ and $1,925{\pm}123.2kg$ in FH; $2,014{\pm}76.7$, $2,264{\pm}91.5$ and $2,096{\pm}123.9kg$ in FBH and $2,005{\pm}87.0$, $2,414{\pm}94.4$ and $2,093{\pm}121.1kg$ in FJH, respectively. The lactation milk yield improved by 12-20% in $F_2$ crosses in various genetic grades. The performance of $F_1$ was, however, maintained in FH $F_3$ crosses, it improved by 4% in FBH and FJH $F_3$ crosses. The lactation lengths and calving intervals were nearly the same for $F_1$, $F_2$ and $F_3$ crosses in FH while lactation lengths and calving intervals were reduced by 3-11% in $F_2$ and $F_3$ crosses in FBH and FJH genetic grades. The milk yield/day of lactation length and milk yield/day of calving interval increased by 16-35% in $F_2$ and 2-14% in $F_3$ over the $F_1$ in various genetic grades. It is recommended that a sufficiently large effective population size of these three genetic grades be maintained by inter se matings and rigorous selection of sires so for developing a genetic base population for new breed development.

  • The aim of this study was to utilize the 20 steps in the three phases from the book, 'Twenty steps for developing a Healthy Cities Project $2^{nd}$ Ed., 1995, WHO/EURO' to survey Healthy Cities to identify the similarities and differences by implementation rates and perceived significances among Healthy Cities worldwide. For this study, a self-administered questionnaire was developed based on the book. The questionnaires were delivered by air-mail and e-mail to 213 Healthy City coordinators or directors in 43 nations from Jan 13 to Feb 10, 1999. The responses were gathered up until March 31 from 40 Healthy Cities in 17 nations, mostly in the USA and in the European regions. The main results are as follows; Overall the perceived significances were higher for healthy cities with higher implementation rates and there were significant differences for 'set-up office', 'plans strategy', 'increase health awareness', 'mobilize intersectoral action', and 'secure healthy public policy'. 1. According to national health system, the implementation rate, perceived significance and implementation ability of the 20 steps were higher in the healthy cities with a comprehensive-type health system as compared to those with an entreprenetrial & permissive health system. Overall there were significant differences in the steps 'mobilize intersectoral action', and 'secure healthy public policy'. steps which were predominant in the healthy cities with a comprehensive-type health system. There was no concordance in the ranks of implementation rate and perceived significant score. 2. According to the length of implementation time, the perceived significance and implementation ability were higher in healthy cities with more than 6 years compared to those with less than 6 years, although implementation rate was the same. Overall there was a significant difference in 'secure healthy public policy' the step which was predominant in the healthy cities with more than 6 years of implementation. 3. According to population covered by the Healthy City Project, the implementation rate and implementation ability were higher in healthy cities with more than a population of 100 thousand. There was no significant difference in perceived significance, but there were differences in the following, 'find finances', 'set-up office'. 'mobilize intersectoral action' in the implementation rate and implementation ability. These three steps were predominant in the healthy cities with a population of more than 100 thousand. 4. The population covered by the Healthy City Project was the only effective factor influencing the total implementation ability of each healthy city, and it was higher for those cities with a population of more than 100 thousand. In Conclusion, the implementation rate, the perceived significance and the implementation ability were higher in cities with a comprehensive -type health system, with more than 6 years of healthy city experience and with a population of more than 100 thousand. To increase the reliability and the validity of the questionnaire and the results of this study arising from lack of sufficient data, repeated study needs to be considered with a more refined questionnaire delivered to more healthy cities worldwide.

  • The purposes of this study were to examine the coping behavior of the elderly in the warning phase of disaster and to explore factors influencing the coping behavior of the elderly. Data were collected from 130 senior citizens aged over 60 who are residing in Pyungchang and Injae of Kangwon province which had damaged by flood disaster in 2006. Perry & Lindell (1997)'s index, a series of six categories that represent coping behaviors which progressively approximate the action of evacuating in the warning phase of disasters was used. Results showed that respondents have high coping skills. Although Activities of Daily Living (ADL) has positive influence on the coping behavior, length of residence has negative effect on the coping behavior of the elderly. This finding proves the elderly are not uncompliant or uncooperative population in the warning phase of disaster. This result also emphasizes the importance of rapid and accurate giving of public warning system of disaster and necessity of prior notification of useful information about natural disaster and effective evacuation plan for the elderly.

  • In this research we present a novel method which combines and visualizes the design model and the FDM-based simulation result of solidification. Moreover we employ VR displays and visualize stereoscopic images to provide an effective analysis environment. First we reconstruct the solidification simulation result to a rectangular mesh model using a conventional simulation software. Then each point color of the reconstructed model represents a temperature value of its position. Next we map the two models by finding the nearest point of the reconstructed model for each point of the design model and then assign the point color of the design model as that of the reconstructed model. Before this mapping we apply mesh subdivision because the design model is composed of minimum number of points and that makes the point distribution of the design model not uniform compared with the reconstructed model. In this process the original shape is preserved in the manner that points are added to the mesh edge which length is longer than a predefined threshold value. The implemented system visualizes the solidification simulation data on the design model, which allows the user to understand the object geometry precisely. The immersive and realistic working environment constructed with use of VR display can support the user to discover the defect occurrence faster and more effectively.

  • Objectives : This study was performed to assess the effectiveness of conservative Korean traditional medical treatment on lumbar intervertebral disc herniation in 12 adolescents. Methods : Data were collected from adolescent patients diagnosed with lumbar intervertebral herniation by MRI, hospitalized at Jaseng Korean Medicine Hospital from January 1, 2014 to December 31, 2015. A total of 12 patients were included in the study. Patients were treated by acupuncture, pharmacopuncture, electroacupuncture, herbal medicine, chuna manual therapy, physical therapy during hospitalization period. To measure treatment outcomes, a verbal numerical rating scale (VNRS), Oswestry disability index (ODI), range of motion (ROM), Straight leg raising test (SLR), and EQ-5D were used. Results : The average age of the participants was $16.05{\pm}1.62$. The average of duration of symptom was $19.25{\pm}26.83(weeks)$ and the average length of hospitalization was $23.8{\pm}16.4(days)$. 2 patients (17 %) suffered from only lumbar pain, while 10 patients (83 %) suffered from lumbar and leg pain. No participant suffered from only leg pain. 8 patients (67 %) were diagnosed with disc herniation in one segment, and 4 patients (33 %) were diagnosed with disc herniation in multiple segments. A total of 17 disc segments (28 %) were herniated. The most herniated lumbar level was L4-5. 3 segments were diagnosed with bulging (17 %), 6 with protrusion (35 %), and 8 with extrusion (47 %). Extrusion was the most frequent herniated type. After treatment, the average VNRS of lumbar pain significantly decreased from $5.58{\pm}1.62$ to $2.91{\pm}1.56$ (p<0.001) and the average VNRS of leg pain significantly decreased from $5.16{\pm}2.51$ to $3.08{\pm}1.8$ (p<0.001). ODI significantly decreased from $48.87{\pm}18.72$ to $28.57{\pm}15.05$ (p<0.05), and EQ-5D significantly increased $0.58{\pm}0.31$ to $0.80{\pm}0.12$ (p<0.05). Range of flexion significantly improved from $61.25{\pm}32.62$ to $68.33{\pm}26.22$ (p<0.05). Conclusion : Conservative Korean Traditional Medical Treatment may be effective in the treatment of lumbar intervertebral disc herniation in adolescence. However, more case reports and clinical research are needed.
