The effect of lxeris sonchifolia H.(godulbaegi) on lipid metabolism were studied in S. D. rats. Twenty four rats were divided into four groups and fed diets containing 1 % cholesterol, 0.25% sodium cholate, 10% coconut oil and 5% lard(control group)f for 3 weeks. An experimental diet group was added with 5% leaf(PL group) or root powder(PR group) of godulbaegi. The lipid components and enzyme activites of serum and liver were assayed. The concentrations of total cholesterol, triglyceride and phospholipid were significantly lower in the PL and PR groups than in the control group. The levels of HDL-cholesterol were not significant but showed somewhat higher values in the PL and PR groups compaired with the control. The activities of glutamic oxaloacetic transminase(GPT) and glutamic pyruvic transaminase(GPT) were significantly lower in the PL and PR groups compaired with the control. In view of these results Godulbaegi is expected to be an effective food in preventing and improving the hyperlipidemic state.

해양경찰은 구조, 재난관리, 치안유지, 마약 및 밀수 단속, 주변국 대응, 환경보전, 해양안보 등 다양한 업무를 수행하는 국내 유일의 해양종합행정기관으로서 그 역할과 임무를 국민에게 제대로 알리는 홍보활동이 매우 중요하다. 하지만 해안가, 도서지역 주민들을 제외한 대부분의 국민들은 일상생활에서 해양경찰의 치안행정 서비스를 직접 접하는 경우가 드물고, 이로 인해 해양경찰의 역할과 임무에 대한 국민들의 이해도는 낮다. 이 연구는 해양경찰 재출범 3년차를 맞아 해양경찰 홍보 조직과 업무 현황을 고찰하고, 일선 홍보담당자를 대상으로 설문조사하여 해양경찰의 홍보 실태를 진단하고, 해양경찰 홍보 강화방안을 제시하였다. AHP분석 결과 해양경찰 홍보는 전담인력 증강 배치를 통해 홍보조직의 내실화를 기하고, 홍보대상에 따른 홍보 전략을 명확히 한 맞춤형 홍보를 강화하며, 홍보 담당자의 직무교육을 강화하고, 홍보 업무에 대한 지휘관 및 내부 구성원의 관심과 지원이 필요한 것으로 나타났다.

Crude catechin extracts were prepared using ethyl acetate from Korean Puerariae Radix (PR) and their biological effects on the alcoholic liver damage were investigated in male Sprague-Dawley rats (6 weeks old). Ethanol (5g ethanol/kg body weight/day) administration was performed for 8 weeks and after ethanol consuming rats were treated with one or two% catechin extracts of diet for 8 weeks. At the end of experimental period, lipid hydroperoxides in liver were analyzed using a chemiluminescence-high performance liquid chromatography (CL-HPLC) method. Compared with control animals, ethanol consumed rats showed lighter body weights, lower ratios of liver/body weight, higher activities of GOT and GPT, and increased lipid hydroperoxide amount in liver. With one or two% catechin extracts treatment, GOT and GPT activities returned to normal ranges. Lipid hydroperoxide contents in liver of on or two% PR treated rats lowered to 20% or 25% respectively, compared with the levels of those ethanol consumed animals without catechin extracts treatment. Therefore, we concluded that on or two% PR crude catechins treatment could be effective for alcoholic liver damage caused by lipid peroxidation.

The coronavirus disease 2019 (COVID-19) pandemic has been ongoing for more than 2 years. Many patients who recover from severe acute respiratory syndrome coronavirus 2 infection continue to have aftereffects such as dyspnea and fatigue, which may lead to functional decline. Therefore, the need for managing these symptoms using methods such as pulmonary rehabilitation (PR) has emerged. The purpose of this study was to report the effectiveness of PR in five patients with acute COVID-19. PR was performed in patients with persistent dyspnea and oxygen demand after COVID-19. All five patients were able to maintain an independent functional status before COVID-19. However, after acute COVID-19, they were unable to walk independently and needed assistance for activities of daily living due to dyspnea and fatigue. Therefore, they were referred to rehabilitation units, and PR was performed. The modified Medical Research Council dyspnea scale, maximal expiratory pressure (MEP), 6-minute walking test, forced vital capacity, and grip strength were assessed before and after PR, and the results were compared. After PR, the parameters improved, except for the MEP in one patient (patient 3) and the grip strength in another patient (patient 4). After PR, two out of five patients returned to work and the other three returned home. Therefore, we conclude that PR is necessary for patients with acute COVID-19 with activity limitations.

PR커뮤니케이션이 기능주의적인 시각에서 벗어나서 다양한 패러다임 접근을 받아들이는 것은 하버마스의 사회비판이론이 도구적인 이성에서 벗어나 광범위한 의사소통 합리성을 추구하는 것과 유사한 맥락에서 이해될 수 있다. 기능주의 함정으로부터 하버마스가 광범위한 합리성 통합을 통해 해답을 찾는 것과 다양한 패러다임의 통합을 통한 'PR커뮤니케이션 민주주의'의 추구는 많은 유사성을 가지고 있다. 이 연구의 목적은 도구적 이성의 왜곡화로 인해 발생하는 현대사회의 병폐를 치유하기 위한 하버마스의 의사소통합리성 기획이 어떤 면에서 PR커뮤니케이션 이론의 패러다임 변화와 맞닿아 있는가를 밝히고, 그러한 두 분야의 유사성으로부터 새로운 PR커뮤니케이션 이론화의 가능성을 모색해 보는 것이다. 또한, PR커뮤니케이션을 통해서 하버마스 사회비판이론의 실천적인 측면을 탐색해 볼 수 있으며, 개인, 조직, 국가차원의 다양한 관계 속에서 대화의 진작, 사회 합의의 도출, 갈등의 해결, 공론 장의 확대와 같은 포괄적인 커뮤니케이션 합리성을 적용해 보는 계기를 마련해 볼 수 있다.

Policy literacy plays a critical role in enhancing deliberative communication among the public, policymakers, and experts. It also helps develop a positive view of policy by the public, which facilitates public acceptance. Despite its importance, however, policy literacy has received little attention in energy policy practice. Therefore, this study explores factors affecting the public's understanding and knowledge (i.e., policy literacy) of nuclear and new-renewable energy policies. Accordingly, we analyzed data from an online survey of 790 laypeople in Korea. Specifically, we examined the effects of trust, transparency, and policy public relations (PR) on the policy literacy of the public regarding the two alternative energy sources. The analysis revealed that people showed higher policy literacy about the alternative sources when provided with more transparent information and exposed to more policy PR activities. However, we found that trust in energy plant operators played a negligible role in improving policy literacy for both energy sources. Based on these findings, we developed some policy suggestions to secure the energy policy literacy of the public.

In this paper, we have isolated six phenolic compounds, such as (+)-catechin (1), taxifolin (2), taxifolin-3-O-${\beta}$-D-(+)-xylose (3), quercetin (4), quercetin-3-O-${\alpha}$-L(+)-rhamnose (quercitrin) (5), apigenin-8-C-rhamnosyl-(1'''${\rightarrow}$2'')-glucoside (2''-O-rhamnosylvitexin) (6) from the EtOAc(Ethyl Acetate) and $H_2O$ soluble fractions of Japanese anise(Illicium anisatum L) leaves and twigs. Also, we have evaluated antioxidative and antiviral activity for each isolated compound. The antioxidative test was DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity. According to the experimental results, all of the isolated compounds indicated the increased radical scavenging activities as the concentration increases and most of the isolated compounds indicated generally good antioxidative values compare to the controls, ascorbic acid and ${\alpha}$-tocopherol. In the antiviral activities, all of the isolated compounds had no potentials in rhinovirus 1B (HRV 1B). But in enterovirus 71 (EV 71) and Influenza virus A/PR/8 (Influenza PR8), only quercetin (4) indicated the good antiviral activity compare to the control. Based on the above results, we found that the phenolic compounds of Japanese anise may be applied for one of the natural biomass sources that can be used as an antioxidant and an antiviral substance.
