국제기아와 같이 멀리 떨어진 사람들을 돕기 위한 메시지는 상황적인 요인의 영향을 많이 받는다. 이러한 관점에서 본 연구는 메시지의 특성(이익/손실 프레이밍)과 개인의 특성(돕기 활동에 대한 사전 태도)이 상호작용하여 메시지 태도와 행위 의도에 영향을 미치는지 살펴보았다. 연구는 220명이 참여한 실험으로 진행하였다. 메시지 태도와 행위 의도에 대한 분석 결과에서 이익/손실 프레이밍과 사전 태도의 상호작용이 유의미하게 발현되었다. 그러한 상호작용은 사전 태도가 상대적으로 우호적인 집단에 대하여 이익 프레이밍이 더 효과적으로 작용하여 발생하였다. 손실 프레이밍에서도 같은 방향성이 나타났지만 그 크기는 상대적으로 작았다. 이러한 상호작용의 방향성은 기대 만족감이 매개하는 것으로 분석되었다. 본 연구의 결과를 토대로 타인을 돕기 위한 메시지의 적절한 기획을 위한 실용적, 이론적 의미를 논하였다.

Background: Patients with lumbar spinal stenosis show abnormal changes in muscle activity due to pain and limited range of motion of the lumbar spine. Excessive increased muscle tone and decreased muscle activity patterns threaten the patients' quality of life. However, there have been a few studies showing how to improve muscle performance in patients with lumbar spinal stenosis. Among these, joint mobilization is one way of improving muscle performance through pain relief and increasing the range of motion. Objectives: To investigate the effect of lumbar mobilization by orthopedic manual physical therapy on paravertebral muscle activity and tone in patients with lumbar spinal stenosis. Design: A randomized controlled trial. Methods: In this study, 24 patients with lumbar spinal stenosis were randomized (1:1 ratio) into two groups. The experimental group underwent lumbar posteroanterior mobilization, and the control group underwent conventional physical therapy (conventional transcutaneous electrical nerve stimulation) for 15 minutes each. For outcome measures, Myoton^®PRO was used to evaluate muscle tone when resting of the paravertebral muscle in the pain area. For muscle activity evaluation, the reference voluntary contraction of the paravertebral muscle was evaluated using surface electromyography. Results: Muscle tone and activity were significantly improved after intervention in both the experimental and control groups. In addition, the experimental group showed more significant decrease in muscle tone and activity than the control group. Conclusion: These results suggest that lumbar mobilization improving muscle performance in patients with lumbar spinal stenosis.

Pueraiae Radix (PR), Pueratia Folium (PF) and Sorbus commixta (SC) mixture, namely GS-SP (PR (1)/PF (2)/SC (0.5): v/v/v) was developed as hangover-relieving elixir and its effects on alcoholic metabolism have been investigated. The enzymatic activity of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) of GS-SP was shown higher than those of single treatment with PR, PL, SC, and the positive control group (YM-808). The survival rate of mouse liver cell line NCTC clone 1469 in the presence of acetaldehyde was 30.6, 22.2, and 8.7% at the GS-SP dosage level of 50, 100, and 200 μg/mL respectively. Different concentrations of 50, 100 and 200 mg/kg of GS-SP showed efficient activity for ADH and ALDH than YM-808 in rat fed with 25% ethanol. The levels of blood alcohol and acetaldehyde after oral administration of 200 mg/kg of GS-SP showed efficient activity of 11.7% and 37% than those of YM-808. These results have been supported to the potential for GS-SP to serve as an excellent potential in providing hangover relief and liver protection.

Purpose: This study was conducted in order to examine premenstrual symptoms (PMS) according to physical activity of high school girls. Method: Data were collected from 323 high school girls using structured questionnaires, Menstrual Distress Questionnaire (MDQ) and International Physical Activity Questionnaire (IPAQ). The data were analyzed using descriptive statistics, t-test, and AVOVA. Results: The mean score of PMS was low (2.200.81). Among the subcategories, negative feeling (2.491.26) was the highest. Physical activity levels were coded as inactive, minimal activity and health enhancing physical activity, among which minimal activity (53.0%) was the highest. Significant differences in PMS were observed according to subjective health condition (F=10.83, p<.001), alcohol intake (t=-1.99, p=.048), caffeine intake (F=3.04, p=.029), dietary habit (F=4.78, p=.009), amount of menstruation (F=4.57, p=.011), discomfort in daily life (F=28.94, p<.001), degree of menstrual pain (F=41.23, p<.001), method of menstrual pain relief (F=4.29, p=.015), and family history (F=11.45, p<.001). Significant difference in PMS was observed according to the physical activity level (F=3.12, p=.046), and health enhancing physical activity (2.540.87) was the highest. Conclusion: These findings suggest that PMS intervention programs would be considered factors related to PMS. Conduct of further studies is recommended for evaluation of the relationship between physical activity and PMS.

Mulberry root bark is one of potential plant sources for antioxidant materials which can be used for the relief of oxidative stress. To explore the effects of solvent type and temperature on the structural characteristics and antioxidant activity of the root bark extracts, we prepared various extracts of mulberry root bark (Morus alba L.) using 0 - 100 % ethanol (EtOH) at RT - 100℃. EtOH concentration and temperature critically affected the extraction yields, the content of bioactive components, and antioxidant activity of the extracts. Use of high content of EtOH solvent and low temperature resulted in the low extraction yield. Meanwhile, it was revealed that the extract prepared using absolute EtOH at room temperature contained polyphenols and flavonoids with the highest contents among other extracts. Interestingly, the temperature differently affected the polyphenol and flavonoid contents according to the solvent types. In the case of 30% EtOH solvent, polyphenol and flavonoid contents increased with an increase in temperature, whereas in the case of 70 and 100 % EtOH, these contents decreased. Using the radical scavenging assay, it was confirmed that the 100% EtOH extracts had higher antioxidant activity compared to distilled water (DW) extracts regardless of temperature. Also, heating might extract more antioxidant components from the root bark. Especially, the extract prepared using 30% EtOH solvent at 100℃ showed the highest antioxidant activity. Taken together, these experimental results imply that the extraction parameters should be designed carefully considering the productivity, the extracted bioactive components, and antioxidant activity.

Tonnage taxation has contributed to developing the Korean maritime industry through tax relief for shipping companies. The current tonnage taxation relies on the net tonnage as an earning-capacity indicator in a merchant ship. Although the tonnage tax accords with horizontal equity, it does not match vertical equity because of the different taxable capacities of an individual company. Nowadays, maritime transport uses a dedicated vessel, and each shipping freight embeds a different value of time. It means the tonnage taxation regime should consider the added value of each shipping freight. Meanwhile, as the environmental regulations led by the International Maritime Organization are being strengthened, the Korean merchant fleet must be eco-friendly soon after. This study explores the alternative to renewing tonnage taxation by utilizing the Greenship certification and considering the ability-to-pay principle. Because the Greenship certification scheme encourages shipping decarbonization, maritime transport by a certified ocean-going vessel comes to be treated as an activity for the green economy. Special taxation for the green economy may contribute to shipping sustainability and market competitiveness.

Recently, there has been inter-Korean exchanges are active, in company with an assertive international activity with North Korea and inter-Korean Summits. Thus, there is a growing possibility of Korean reunification. However, when the unification situation occurs, population inflow by North Korean residents will be expected, and it will be necessary to prepare a housing supply strategy. In addition, even if North Koreans are prevented from entering, a plan is necessary to ensure structural safety since most buildings in North Korea are aging and a recent natural disaster occurs frequently. In this research, we will try to present a temporary housing supply strategy and a short-term structural reinforcement plan based on analysis of the standard housing conditions in North Korea. In this research, we represent the analysis result of the existing construction level, supply status and structural performance of North Korea. When we consider the reinforcement period and social costs, a short-term reinforcement plan is recommended rather than the full reinforcement of the aged housing in North Korea. Furthermore, we examine the ways to secure the residential safety of North Koreans through a case study of domestic and overseas temporary residential facilities, until the permanent residential facilities were supplied. According to the analysis, the tent houses were used as a form of relief housing in overseas frequently. However, the tent house is difficult to apply for domestic country with clear seasons due to insulation and heating problems. Therefore, it is appropriate to develop a residential supply strategy as focusing on the temporary housing facilities in assembled or container from, in preparation for the future population inflow.
