The purpose of this study was to investigate the middle school and high school student's environmental consciousness and clothing behavior for environmental protection in their home, and to present the basic educational material for the reasonable clothing behavior which could help the environmental problems. This study was done by self-administered questionaires to the 439 middle school and high school students, and done from March to April in 1997. Frequencies, percentages, mean, and standard deviation were calculated. $\chi$$^2$-test, t-test, and F-test were done for group differences, and Duncan's multiple range test was followed. The results of this study were as follows ; 1. Environmental consciousness was higher at the middle school students, at good graded students, and at the good news receivers who watch or listen to the mass media frequently. And also environmental consciousness was higher at the students who separate and dispose waste practically and at those who realize the need of environmental education. 2. Those who purchase clothes reasonably in their home, practising the clothing behavior for environmental protection, were the middle school students, and the students sho watch or listen news frequently through the mass media. And those who manage clothes well in their home were the middle school students, metropolitan area residents, good news receivers, and residents in apartments. Those who separate and dispose waste well, those who have experienced much environmental education, those who know better the environmental protection marks which are attatched to the low pollution products and those who realize the need of environmental education seriously, were almost the same students who buy and manage clothes reasonably in their home, practising the clothing behavior for the environmental protection. And those who feel much more environmental education seriously were those who reuse clothes practically in their home. 3. As the students had the higher environmental consciousness level, the better they practised the clothing behavior for environmental protection in their home. The major sources of the students'knowledge and information about environment were from the mass medea, and then from school teachers.

Today many companies are offering IoT-enabled products and place emphasis on security from the planning stage to protect their products and user information from external threats. The present security levels, however, remain low because the time and resources invested in developing security requirements for each device are far from enough to meet the needs of a wide range of IoT products. Nevertheless, vulnerabilities of IoT devices have been reported continuously, which calls for more detailed security requirements for home IoT devices. In this context, this research identified threats of home IoT systems by using Microsoft Threat Modeling Tool. It then suggested measures to enhance the security of home IoT devices by developing security assessment items through comparative analysis of the identified threats, domestic and global vulnerability assessment standards and related research. It also verified the effectiveness of the developed security requirements by testing them against the existing ones, and the results revealed the security requirements developed in this research proved to be more effective in identifying vulnerabilities.

A research program for the roe deer (Capreolus pygargus) has been set up at the Jeju Experimental Forest of Warm-temperate and Subtropical Forest Research Center in Jeju Island. To explore the home range size and habitat environment, 3 males and 3 females have been captured and released with GPS-CDMA based telemetry since 24th April 2012. Among them 2 females were captured at Hannam Forest of Seoguipo, were pregnant and monitored by the tracking system. There are significantly different patterns in behavior around the parturition. After parturition they show recurrence behavior toward one point in the forest, while they have irregular patterns in moving before. To calculate the home range size, the MCP (minimum convex polygon) and Kernel Method are applied through the extension of ESRI ArcView GIS 3.2a. The pregnant female captured 9th May 2012 has the size of MCP=67ha and Kernel 95%=0.5ha and the pregnant female captured 12th July 2012 has the size of MCP=82ha and Kernel 95%=0.9ha. Although a fawn could move immediately just after the birth likely others to avoid any risks, they stay at very narrow space significantly, and the size become wider when more time goes by. Furthermore, they mainly have a home range away from human activity area such as forest tracking roads. The habitat environment for the parturition is summarized as 40years old cryptomeria forests with new sprouting shrubs for foods, which are the controlled forest through the thinning and removing shrubs 2 years ago. This means that forest works could cause positive results for the parturition and survival of young. The period of parturition is earlier than highland in Jeju Island, the size of home range is narrower than other countries, and the habitat environment of the shelter for a fawn is similar to previous research in other countries.

The central purpose of this paper is to examine impulsive buying from home shopping channels and to investigate some stimulating factors of marketing on the customers' impulsive buying. on TV. Survey questionnaires were given to 303 customers who have purchased products through TV home shopping more than once. We report the following findings. First, we find that product stimuli factors exert an effect on impulsive buying of fashion goods, but not of specialty goods. Second, of the two promotion stimuli factors a bonus pack and an extended payment period-the latter is shown to have a great effect. Third, in the case of price stimuli factors, concrete stimuli such as a discount range have a greater influence than abstract stimuli such as a reliable pricing. Finally, in the area of situational stimuli factors, speeches of show hosts have a bigger impact than buying situations such as limit selling. We believe that the current research provides a significant result, theoretically and practically, with respect to customers' behavior in TV home shopping. The methodological limitation involving samples and sampling method and the regional limitation make it difficult to generalize the findings. It should be worthy classifying and managing marketing stimuli. More practical research is in order.

The black rockfish (Sebastes schlegeli) is an important commercial species in Korean fisheries. We used acoustic telemetry using coded ultrasonic transmitters to track the home ranges and homing routes of the black rockfish that inhabit in the Tongyeong marine ranching area. Twenty-four fish were released at five points. The distance from the capture point (C1) to the released point was 0 (R7), 0.2 (R1), 0.9 (R2), 1.3 (R3) and 1.9 (R4) km. Two of the three fish released at R1 (0.2 km) returned home in under 48hrs. Another was found 0.8km from C1. Two of the five fish released at R2 returned home, but it took over 250 days. None of the ten fish released at R3 and R4 returned home. Three of the ten fish moved 1.1-2.6 km from C1 and were found near a cage or a natural reef. Six fish were released at R7. The younger the fish, the wider was its movement range around the artificial reefs. Fish over 3 years old were likely to move less far.

Recently in the area of ICT, the M2M and IoT are in the spotlight as a cutting edge technology with the help of advancement of internet. Among those fields, the smart home is the closest area to our daily lives. Smart home has the purpose to lead a user more convenient living in the house with WLAN (Wireless Local Area Network) or other short-range communication environments using automated appliances. With an arrival of the age of IoT, this can be described as one axis of a variety of applications as for the M2H (Machine to Home) field in M2M. In this paper, we propose a novel technique for estimating the location of a terminal that freely move within a specified area using the RSSI (Received Signal Strength Indication) in the WLAN environment. In order to perform the location estimation, the Fingerprint and KNN methods are utilized and the LMS with the gradient descent method and the proposed algorithm are also used through the error correction functions for locating the real-time position of a moving user who is keeping a smart terminal. From the estimated location, the nearest fixed devices which are general electric appliances were supposed to work appropriately for self-operating of virtual smart home. Through the experiments, connection and operation success rate, and the performance results are analyzed, presenting the verification results.

Purpose: The purposes of this study were; 1) to test the validity and reliability of the Korean version of Rantz's Observable Indicators of Nursing Home Care Quality Instrument (ONHQ) and 2) to evaluate the quality of Korean nursing homes. Methods: The study employed a three-phase methodological research design. 1) The original instrument of Rantz's. ONHQ was translated into Korean and modified by Korean nursing home experts. 2) A pilot study using the modified instrument was done in 20 nursing homes to examine inter-rater reliability. 3) The validity and reliability were tested.in 98 nursing homes. Results: Seven factors were extracted through factor analysis: 'communication', 'care delivery', 'grooming', 'odor, 'environment-basics', 'environment-access', and 'environment-homelike'. These factors explained 86.07% of the total variance. Cronbach's alpha coefficient of the 30 items was .97 indicating a high internal consistency of the instrument. Inter-rater reliability according to Kappa was .82. The average score of nursing home quality was 112.07 indicating an average range of quality level. Conclusion: The Korean version of the ONHQ was identified as a tool with a high degree of validity and reliability. This tool can be effectively used to assess the quality of nursing homes by professions as well as family members.

The purpose of this study is to identify the home range and habitat using pattern of the native species, Mauremys reevesii, and the exotic species, Trachemys scripta elegans, and to analyze the mutual competition relationship of the two species. This study was conducted at the Goldfish square pond, which is located in the upper part of the valley of Cheonggye mountain from August 2, 2010 to January 30, 2011. We used the three artificially proliferating M. reevesii and three T. scripta elegans which were inhabited in the ponds and reservoirs for monitoring study after attaching the transmitter to each of them. We measured the home range and the habitat utilization radius of three individuals of each species and the environmental factors such as temperature, humidity and soil and water temperature around the Goldfish square pond. As our results, it was analyzed that the M. reevesii and T. scripta elegans have a redundant ecological positions in various aspects such as limited sunbathing places, food resource utilization, hibernation place, etc. We also found that the relatively small M. reevesii was being pushed out of the competition by the relatively big. Further investigation of food competition and habitat utilization should be necessary for these two species for the natural habitats, their home range, food competition, and habitat utilization. The result of this study will be the basic data M. reevesii's restoration project.

Background: This study was undertaken to compare the outcome of supervised and home exercises with respect to range of motion (ROM), pain, and Single Assessment Numeric Evaluation (SANE). We further correlated the ROM recovery and pain reduction as well. Methods: The study included 49 patients who underwent arthroscopic rotator cuff repair. Rehabilitation was initiated after 4 weeks of immobilization. A total of 29 patients performed supervised exercise 3 times a week. Standardized education and brochures for review were provided to the remaining 20 patients who insisted on home rehabilitation. Statistical analysis was performed for comparing pain Numerical Rating Scale (NRS), SANE, and ROM. In addition, we also evaluated the correlation between pain and ROM. Results: Comparison of the two groups revealed no significant differences in forward flexion, internal rotation, abduction, and pain NRS. However, SANE at the 9th week (63.8 vs. 55.0, p=0.038) and improvement of external rotation from the 5th to the 9th week (17.6 vs. 9.3, p=0.018) were significantly higher in the supervised exercise group as compared to the home exercise group. Correlation of pain NRS with forward flexion, external rotation, internal rotation and abduction were statistically not significant (correlation coefficient=0.032 [p=0.828], -0.255 [p=0.077], 0.068 [p=0.642], and -0.188 [p=0.196], respectively). Conclusions: The supervised rehabilitation after arthroscopic rotator cuff repair showed better improvement in external rotation and higher SANE score after 4 weeks of rehabilitation exercise. However, no statistically significant correlation was observed between the recovery of ROM and short-term pain relief.
