  • In this paper, we consider trellis-coding techniques with the convolutional encoder R=k/(k+1) for improving the reliability of digital transimission over bandlimited noisy PRS and 49-QPRS channels. Employing the R=k/(k+1) convolutional code for the PRS channel results in over 3 dB of coding gain comparing with the baseline system. The trellis-coded 49-QPRS system can be realized by combining the 9-QPRS system with the R=1/2 convolutiona code, which can be improved by over 2dB coding gain comparing with the 9-QPRS system. In additin, we study a method of avoiding the occurance of unlimited runs of identical output to prevent operation of timing error.

  • The purpose of this study is to investigate the effects of the exhibition displays and events of the Agro-healing Experience Hall in the Agricultural Technology Exhibition 2018 on satisfaction and revisit intention of visitors. A survey was conducted on visitors of the Agro-healing Experience Hall and the responses of 274 visitors excluding 26 cases with inappropriate responses were analyzed. For psychological measurement, the Perceived Restorativeness Scale (PRS), Profile of Mood States (POMS), level of plant gardening experience, satisfaction and loyalty were measured. There was a significant difference among age groups in all four factors of the PRS (repose, fascination, coherence, and legibility). In the case of education level, there was a significant difference in the three factors (repose, fascination, and legibility). In addition, average monthly income showed a significant difference among groups in the two factors (fascination and coherence). As a result of analyzing the mood states of visitors for the exhibition events of the Agro-healing Experience Hall, there was a significant difference among age groups only in the case of vigor (p < .05). As a result of analyzing the correlation between the level of plant gardening activities (3 factors) and PRS (4 factors) in the exhibition events of the Agro-healing Experience Hall, plant preference tendency and plant-related event showed a high positive correlation of 0.5 or more with repose of the PRS factors. A multiple regression analysis was conducted to investigate the effects of the level of plant gardening activities, PRS and POMS on the satisfaction and loyalty of visitors. As a result, it was found that in terms of relative explanatory power over independent variables affecting satisfaction and revisit intention, fascination had the greatest effect, followed by vigor, fatigue, and occupation (company employee). The results of this study suggest that exhibition events of the Agro-healing Experience Hall affect repose, fascination or vigor of visitors, and thus can be used positively to increase satisfaction and revisit intention of visitors.

  • Background and objective: The purpose of this study is to investigate the effects of visitors' positive emotions on satisfaction and loyalty with the perception of restorative environment of a healing garden created in an urban agriculture expo. Methods: The psychological indicators to the images of the healing garden were analyzed by the visitors' demographic variables and the three factors of plant cultivation activity level: plant cultivation experience, plant preference, and plant-related event. Results: Between age groups and occupational groups, significant differences were found statistically. The Perceived Restorativeness Scale(PRS) showed significantly differences between age groups in repose, fascination and legibility. The Positive Affect & Negative Affect Schedule(PANAS) showed statistically significant differences between age groups in positive emotions. In addition, we investigated the correlation between the PANAS and the three factors of plant cultivation experience level, the four factors of the PRS, satisfaction and loyalty. The three factors of plant cultivation experience level, the four factors of the PRS, satisfaction and loyalty showed a positive correlation with positive emotions and were inversely correlated with negative emotions significantly. Multiple regression analysis with dummy variables was conducted to examine the effects of plant cultivation activity level, attention restoration, and the PANAS on healing garden visitors' satisfaction and loyalty. As a result, among the four factors of the PRS, fascination and positive affectivity were significant variables that affect healing garden visitors' satisfaction and loyalty. Conclusion: The results indicated that the higher the attention restoration of visitors due to the fascination of the healing garden and the higher their positive affectivity and the more they have plant-related memories, the higher their impact on healing garden visitors' satisfaction and loyalty. Therefore, fascinating natural environments or greenery landscapes like healing gardens where people can contact plants would reduce negative emotions such as anger and sadness but to increase positive emotions such as pleasure, joy and satisfaction.

  • 성인기의 양극성장애와 정신분열병 환자에서 아동기에 주의력결핍-과다활동 증상을 조사하여 서로의 연관성을 알아보고자 하였다. 저자들은 40세 미만의 남자 중 원주기독병원에서 추적진료중인 26명의 양극성장애군, 29명의 정신분열병군, 그리고 27명의 정상대조군에서 Wender Utah Rating Scale(WURS), WURS 25개 항목(WURS-25), Parent Rating Scale(PRS)을 이용하여 아동기의 주의력결핍-과다활동 증상을 비교하였다. 양극성장애군은 정상대조군과 비교하여 WURS의 평균득점이 의미있게 높았다. WURS-25와 PRS의 평균득점도 양극성장애군이 다른 두 군에 비해 의미있게 높았다. 그러나 정신분열병군에서 WURS, WURS-25, PRS 각각의 평균 득점은 정상대조군과 유의한 차이가 없었다. WURS와 PRS는 양극성장애군과 정상대조군에서 상관관계를 보였지만 정신분열병군에서는 상관관계가 없었다. 양극성장애군에서 정신분열병군과 정상대조군에 비해 아동기의 주의력결핍-과다활동 증상이 더 많았으며, 이 결과는 양극성장애와 주의력결핍-과다활동장애의 연관성을 시사한다.

  • Background: Intra-articular injection is a commonly performed procedure in patients with degenerative osteoarthritis of the knee. Several drugs are used for relief of pain in such cases. Local anesthetics, clonidine and steroids have been confirmed to be effective when used in an intra-articular injection. Ketorolac has recently become one of the most commonly used and potent NSAIDs. There have been many studies about the effect of ketorolac. Methods: Sixty-four patients were divided into 2 groups. In Group I (n = 31), 0.5% bupivacaine 3 ml and sodium hyaluronate 20 mg were used and in Group II (n = 33), 0.5% bupivacaine 3 ml, sodium hyaluronate 20 mg and ketorolac 5 mg were used. We observed the pain relief scale (PRS) at 15 minutes, 1 week and 1-3 months after injection. Results: After 15 minutes, PRS scores were $6.6{\pm}2.7$ (Group I) and $5.1{\pm}3.1$ (Group II), so there was a statistical difference between the two groups. After 1 week, the PRS scores were $5.9{\pm}2.0$ (Group I) and $5.8{\pm}2.4$ (Group II). At 1-3 months later, PRS scores were $5.6{\pm}3.0$ (Group I) and $5.1{\pm}2.7$ (Group II). Thus, there were no significant statistical differences between the two groups at 1 week or 1-3 months later, although some patients were more satisfied with pain relief in Group II at 1-3 months. Conclusions: Ketorolac provides more rapid pain relief of degenerative arthritis when used in intra-articular injection. And there was no statistical difference of effect after 1 week or 1-3 months later. Further studies are required on the effect of the intra-articular use of ketorolac.

  • Male weanling Sprague Dawley rats were used to evaluate the effect of dietary rice starch with different particle size on growth performance, intestinal function and proliferation. There were two dietary treatment: rice starch (RS), ultra finely pulverized rice starch with less than $15{\mu}m$ size (PRS). They were eight rats per treatment. In vitro digestibility, body weight change and organs weight were evaluated. Serum GPT, GOT and blood urea nitrogen were analyzed. Transit time, short chain fatty acid contents of cecum, and cell proliferation of duodenum and jejunum were measured. In vitro digestibility of PRS was higher than that of RS. Rats fed ultra finely pulverized rice starch for 3 weeks grew faster than rats fed rice starch. PRS group has higher weights of liver, kidney, spleen and epididymal fat pad, perhaps as a result of increased digestibility. GPT and GOT were not different between two groups. Blood urea nitrogen was higher in RS-fed rats than that of PRS-fed rats. Feeding ultra finely pulverized rice starch resulted in a proliferation of duodenum significantly. These results suggest that ultra finely pulverized rice starch increases the growth performance in weanling animals with reduced number of cells in the cell cycle of small intestine.

  • This paper proposed a partial resonant switching three-phase high power factor converter using a $PRS^2$(Partial Resonant Soft Switch). The proposed converter has a merit of simple controlled circuit because the input current control DCM(Discontinuous Conduction Mode). And it is improve to input power factor that the snubber capacitor's energy regenerate to the AC source side. This topology is reduced a current/voltage stresses of resonant devices in addition to a partial resonant strategy. The result of simulations with the proposed topology included in this paper.
