This study was performed to investigate the effect of water extracts from Namhae special crops (NSC) on improved serum lipid composition using rats fed a 1% cholesterol diet for 4 weeks. Male Wister rats (200-210 g) were divided into six groups: Normal cholesterol diet group (Normal), 1% cholesterol diet group (Control), 1% cholesterol and NSC water extract powder supplemented groups, including, turmeric (Tu-EP), cactus (Ba-EP), aloe vera (Al-EP) and asparagus (As-EP). No significant differences were observed for food intake or body weight gain between the control and experimental groups. However, food efficiency ratio (FER) was the lowest in the As-EP group. The serum levels of total cholesterol and triglycerides in the NSC water powder extract supplement groups were lower than those in the control group. The serum high density lipoprotein (HDL)-cholesterol content in the Tu-EP group was higher than that in the other experimental groups. Very low density lipoprotein (VLDL)-cholesterol content in the As-EP group was similar to that in normal group. Furthermore, the VLDL content in the Al-EP group was lower than that in the normal group. Serum antioxidant activity by TBARS level and DPPH radical scavenging were significantly higher in the Ba-EP group than that in the control group. Hepatic total cholesterol and lipid content in the Al-EP group decreased significantly compared to that in the control group. These results suggest that the NSC water extract may reduce serum cholesterol and prevent oxidative stress by stimulating antioxidative systems in rats fed a 1% cholesterol diet.
This study has been done in order to analyze the relationship between climacteric symptoms and the stress of life events. For the purpose of this study. objectives set up were as followings. : 1. Climacteric symptoms complained by middle aged women are studied. 2. The stress of life events experienced by middle aged women is studied. 3. The relationship between climacteric symptoms and the stress of life events is studied. 4. The relationship between climacteric symptoms and general characteristics is studied. and the relationship between the stress of life events and general characteristics is also studied. The sample size of this study was 462 cases. The subjects were middle-aged women. who were from 40 to 60 years old and resided in Seoul. Data were collected by using questionnaires which consisted of 122 questions from Jan. 1 to Feb. 7 in 1992. The questionnaires include questions about general characteristics. climacteric symptoms and life events. The measurement scales for this study were adopted from the climacteric symptoms scale developed by Chi. Sung-Ai and the measurement scale of stress related to life events devised by Lee. Pyoung Sook. The analysis of data collected was done by using SPSS-pc package. Firstly. general characteristics were analyzed by using descriptive statistical methods. Secondly. climacteric symptoms were analyzed by using descriptive statistical methods. the analysis of variance and correlation analysis. Thirdly. the stress of life events was studied by using descriptive statistical methods. the analysis of variance. and tests of independence. The results of this study are as followings. 1. General characteristics of the respondents are as followings: The average age is 49. 13. and the age group from 46 to 50 has $30.5\%$ in the respondents. Christianity is the major religion $(42.6\%)$. and the respondents with a high school diploma are $(43.1\%)$ of the respondents. $60\%$ of all respondents are housewives. and $90.5\%$ are married. The average number of children is 2.71. and the average number of family is 4.24 Monthly income of $39.1\%$ of the respondents is from l,010,000 Won to 2,000,000 Won. The premenopausal group is $4.9\%$. and $45.5\%$ of all respondents are satisfied with marrital life. $43.3\%$ of all feel happy. and $13.9\%$ feel economic frustration. $27.9\%$ of respondents are satisfied with sexual life. and $45\%$ of all report that the amount of recreational activities are more needed. 2. The average score of climacteric symptoms is 1. 8461 (The maximum score is 5.0). The symptoms complained frequently are nervousness. muscle-ache. fatigue. headache and knee-ache. Climacteric symptoms are significantly different in menopausal states. age groups. the number of children, marrital satisfaction. the feeling of life. self-reported health states and sexual satisfaction. 3. The life events occurred frequently were 'discord with husband', 'children's important exams', 'separation from husband related to works' and 'vacation'. When life events are analyzed by factors. the most frequently mentioned factor is 'marrital life'. The stress of life events is significantly different in a few general characteristics (age. the number of children, the number of family, monthly income, menopausal status, the feeling of life. self-reported health states, economic satisfaction). 4. The score of climacteric symptoms complained is significantly different according to the stress of life events (p<0.051, Especially, the difference is the widest in psychological symptoms according to the factor of 'couple. marrital life' among stressful life events. In Summary, climacteric symptoms complained by middle-aged women are related to the amount of the stress of life events. Whether life events are positive of negative is not important. Yet. climacteric symptoms and stressful life events are deeply related to general characteristics. so we can not insist strongly that one be directly related to the other.

Antioxidant activities of ethanol and water extracts from Orostachys japonicus leaf, stem, and root were determined by rancimat method, DPPH radical scavenging effect, chelating effect, and reducing power analysis. The highest total phenolic compound (TPC) as 14.6 mg/g of dry sample and the strongest antioxidant activity in rancimat method (value of AI 1.98), DPPH radical scavenging effect (96% in 4 mg/mL), and reducing power (1.50 in 4 mg/mL) were observed in ethanol extracts from Orostachys japonicus leaf. Heat and pH stabilities on antioxidant activity of Orostachys japonicus leaf extract were studied through TPC and DPPH radical scavenging effect. As a result, the extracts from Orostachys japonicus leaf showed high stability. These results suggest that extracts from Orostachys japonicus leaf can be potentially used as proper natural antioxidant in the food industry.
The Fundamental purpose of the Warsaw Convention was to establish uniform rules applicable to international air transportation. The emphasis on the benefits of uniformity was considered important in the beginning and continues to be important to the present. If the desire for uniformity is indeed the mortar which holds the Warsaw system together then it should be possible to agree on a worldwide liability limit. This liability limit would not be so unreasonable, that it would be impossible for nations to adhere to it. It would preclude any national supplemental compensation plan or Montreal Agreement type of requirement in any jurisdiction. The differentiation of liability limits by national requirement seems to be what is occurring. There is a plethora of mandated limits and Montreal Agreement type 'voluntary' limits. It is becoming difficult to find more than a few major States where an unmodified Warsaw Convention or Hague Protocol limitation is still in effect. If this is the real world in the 1980's, then let the treaty so reflect it. Upon reviewing the Warsaw Convention, its history and the several attempts to amend it, strengths become apparent. Hijackings of international flights have given rise to a number of lawsuits by passengers to recover damages for injuries suffered. This comment is concerned with the liability of an airline for injuries to its passengers resulting from aviation terrorism. In addition, analysis is focused on current airline security measures, particularly the pre-boarding screening system, and the duty of air carriers to prevent weapons from penetrating that system. An airline has a duty to exercise a high degree of care to protect its passengers from the threat of aviation terrorism. This duty would seemingly require the airline to exercise a high degree of care to prevent any passenger from smuggling a weapon or explosive device aboard its aircraft. In the case an unarmed hijacker who boards having no instrument in his possession with which to promote the hoax, a plaintiff-passenger would be hard-pressed to show that the airline was negligent in screening the hijacker prior to boarding. In light of the airline's duty to exercise a high degree of care to provide for the safety of all the passengers on board, an acquiescene to a hijacker's demands on the part of the air carrier could constitute a breach of duty only when it is clearly shown that the carrier's employees knew or plainly should have known that the hijacker was unarmed. A finding of willful misconduct on the part of an air carrier, which is a prerequisite to imposing unlimited liability, remains a question to be determined by a jury using the definition or standard of willful misconduct prevailing in the jurisdiction of the forum court. Through the willful misconduct provision of the Warsaw Convention, air carrier face the possibility of unlimited liability for failure to implement proper preventive precautions against terrorist. Courts, therefore, should broadly construe the willful misconduct provision of the Warsaw Convention in order to find unlimited liability for passenger injuries whenever air carrier security precautions are lacking. In this way, the courts can help ensure air carrier safety and prevention against terrorist attack. Air carriers, therefore, would have an incentive to increase, impose and maintain security precautions designed to thwart such potential terrorist attacks as in the case of Korean Air Lines Flight No.858 incident having a tremendous impact on the civil aviation community. The crash of a commercial airliner, with the attending tragic loss of life and massive destruction of property, always gives rise to shock and indignation. The general opinion is that the legal system could be sufficient, provided that the political will is there to use and apply it effectively. All agreed that the main responsibility for security has to be borne by the governments. I would like to remind all passengers that every discovery of the human spirit may be used for opposite ends; thus, aircraft can be used for air travel but also as targets of terrorism. A state that supports aviation terrorism is responsible for violation of International Aviation Law. Generally speaking, terrorism is a violation of international law. It violates the soverign rights of the states, and the human rights of the individuals. I think that aviation terrorism as becoming an ever more serious issue, has to be solved by internationally agreed and closely co-ordinated measures. We have to contribute more to the creation of a general consensus amongst all states about the need to combat the threat of aviation terrorism.

Backgrounds : Obstructive sleep apnea syndrome(OSA) can divided into two groups, positional(PP) and non-positional(NPP) obstructive sleep apnea syndrome, according to the body position while sleeping. In this study, we evaluated the differences of anthropometric data and polysomnographic recordings between the two types of sleep apnea syndrome. Materials : Fifty patients with OSA were divided two groups by Cartwright's criteria. The supine respiratory disturbance index (RDI) was at least two times higher than the lateral RDI in the PP group, and the supine RDI was less than twice the lateral RDI in the NPP group. This patients underwent standardized polysomnographic recordings. The anthropometric data and polysomnographic data were analyzed, statistically. Results : Of all 50 patients, 30% were found to be positional OSA. BMI was significantly higher in the PP group(p<0.05). Total sleep time was significantly longer in the PP group (350.6$\pm$28.2min, 333.3$\pm$46.0min, (p<0.05). Sleep efficiency was high in the PP group(89.6$\pm$6.4%, 85.6$\pm$9.9%, p<0.05). Deep sleep was significantly higher and light sleep was lower in the PP group than in the NPP group but no difference was observed in REM sleep between the two groups. Apnea index(AI) and RDI were significantly lower( 17.0$\pm$10.6, 28.5$\pm$13.3, p<0.05) and mean arterial oxygen saturation was higher in the PP group(92.7$\pm$1.8%. p<0.05) than in the NPP group. Conclusion : Body position during sleep has a profound effect on the frequency and severity of breathing abnormalities in OSA patients. A polysomnographic evaluation for suspected OSA patients must include monitoring of the body position. Breathing function in OSA patients can be improved by controlling their obesity and through postural therapy.

This study was conducted for the antihyperlipidemic effect of ethanol extract from Portulaca oleracea in high fat diet-induced obese mice after having injected the ethanol extract from Portulaca oleracea to the obese mice with high fat diet. The 30 six-week-old male C57BL/6J mice were divided into 3 groups of 10 and fed for 5 weeks to be obese with high fat diet. Thereafter, for 4 weeks, ethanol extract from Portulaca oleracea was provided through oral injection to the 3 groups: control group (HFD), group injected with 75 mg/kg of ethanol extract from Portulaca oleracea (HFD+POE 75) and the group injected with 125 mg/kg of ethanol extract from Portulaca oleracea (HFD+POE 125). The serum and liver lipid and the alanine transaminase (ALT) and aspartate transaminase (AST) activity were measured. The result showed that there was no significant difference in weight gain and feed intake, and the feed efficiency ratio was significantly low in the group provided with ethanol extract from Portulaca oleracea. Serum total cholesterol was significantly low in the group of ethanol extract from Portulaca oleracea (HFD+POE 125). It appeared that all the groups provided with ethanol extract from Portulaca loeracea reduced plasma triglyceride significantly according to the ethanol extract from Portulaca oleracea dose. There was no dose dependency of HDL-cholesterol to the dose of ethanol extract of Portulaca oleracea. LDL-cholesterol was low in the group dosed with high ethanol extract from Portulaca oleracea (HFD+POE 125). There was difference of total cholesterol, triglyceride and total lipid contents in liver. AI (atherogenic index) and CRF (cardiac risk factor) were significantly low in the group with high dose of ethanol extract from Portulaca oleracea (HFD+POE 125). There was no difference of serum AST activity, however, serum ALT activity was significantly low in the group with high dose of ethanol extract from Portulaca oleracea (HFD+POE 125).

The human population is mainly exposed to dioxins through the diet. The purpose of this study was to estimate the daily dietary intake of PCDDs and PCDFs in Korean adults residing in different regions. Subjects were recruited and divided into three groups according to the districts where they lived: rural (n=213), coastal (n=193), and urban district (n=187). Subjects were interviewed using a general questionnaire and 24-hour recall for dietary intake. The daily intake of dioxins was estimated through the use of the database of dioxins contents in 35 Korean foods. The average age of the subjects were 61.5 years for coastal district, 57.6 years for rural district, and 49.4 years for urban district. Daily energy intake was 1707.7 kcal for rural district, 1596.5 kcal for urban district, and 1493.8 kcal for coastal district. There was no significant difference in total food intake by regions. The intakes from fishes of coastal district, those from cereals, vegetables, meats, and seasonings of rural district, and those from sugars, pulses, eggs, seaweeds, milks, oils of urban area were higher than those of the other two districts. The daily dioxins intake of coastal district (0.70 pgTEQ/kg/day) was significantly higher than those of rural district (0.32 pgTEQ/kg/day) and urban district (0.46 pgTEQ/kg/day). The dioxins intake from cereals, pulses, vegetables, fishes of coastal district and those from eggs and milks of urban area were the highest among the districts. The daily dioxins intake was positively correlated with the intakes of meats, eggs, fishes, oils, and seasonings. Therefore, it could be concluded that the daily dioxins intake of coastal district is higher than that in other districts and the fish is one of the main sources in dioxin intakes. However, daily dioxins intakes of the three regions were below the level of tolerable daily intake (TDI).
In this study, we investigated the effect of offline banking trust on smart banking trust. As influencing factors of smart banking trust, this study compared offline banking trust, smart banking's system quality, and information quality. For the empirical study, 186 questionnaire data were collected from smart banking users and the data were analyzed using Smart-PLS 2.0. As results, it was verified that there is trust transfer in FinTech service, by the significant effect of offline banking trust on smart banking trust. And it was proved that the effect of offline banking trust on smart banking trust is lower than that of smart banking itself. The contribution of this study can be seen in both academic and industrial aspects. First, it is the contribution of the academic aspect. Previous studies on banking were focused on either offline banking or smart banking. But this study, focus on the relationship between offline banking and online banking, proved that offline banking trust affects smart banking trust. Next, it is the industrial contribution. This study showed that offline banking characteristics of traditional commercial banks affect the trust of emerging smart banking service. This means that the emerging FinTech companies are not advantageous in the competition of trust building compared to traditional commercial banks. Unlike traditional commercial banks, the emerging FinTech is innovating the convenience of customers by arming them with new technologies such as mobile Internet, social network, cloud technology, and big data. However, these FinTech strengths alone can not guarantee sufficient trust needed for financial transactions, because banking customers do not change a habit or an inertia that they already have during using traditional banks. Therefore, emerging FinTech companies should strive to create destructive value that reflects the connection with various Internet services and the strength of online interaction such as social services, which have an advantage over customer contacts. And emerging FinTech companies should strive to build service trust, focused on young people with low resistance to new services.

This research was performed to investigate the effect of aged Deodeok (Codonopsis lanceolata) water extracts on the levels of lipids in the serum of rats fed a high-fat diet for 10 weeks. Experimental groups were divided into basal diet only (BDG), high fat diet control (HFDCG), high-fat diet and 10% aged deodeok extract powder (HF10S), and high-fat diet and 20% aged deodeok extract powder (HF20S) groups. The levels of hematological variables were not significantly different among the four groups. Compared with the control group's serum total cholesterol level of $339.38{\pm}4.06mg/dL$, the levels of the HF10S and HF20S groups were significantly lowered to $225.38{\pm}5.44$ and $215.02{\pm}4.77mg/dL$, respectively. Compared with the control group's LDL-cholesterol leve of $64.91{\pm}3.67mg/dL$, the LDL-cholesterol levels of the HF10S and HF20S groups were significantly lowered to $54.16{\pm}3.46$ and $46.14{\pm}1.79mg/dL$, respectively. Also, compared to the control group's serum triglyceride level of $103.07{\pm}13.2mg/dL$, the level of the HF20S group was significantly lowered to $48.25{\pm}11.52mg/dL$. These results suggested that dietary supplementation of aged deodeok extract does not have any adverse effect on the hematological variables, while improving the lipid content and reducing hepatic damage of the high-fat fed rats.

In an open labeled study, two fixed doses of nimodipine(45mg and 90mg daily) were added to the usual antipsychotic drug treatment (Haloperidol : mean dose=25mg/day) in 20 male chronic schizophrenics for 5 weeks. The purposes of this study were to evaluate the therapeutic effects and the effect an the changes of plasma homovanillic acid(HVA) and 5-hydroxyindoleacetic acid(5-HIAA) levels. The results were as follows : 1) Total BPRS score and thought cluster, paranoid cluster subscores showed linear decreasing trend over the course of the study(P<0.05). Especially the thought cluster and paranoid cluster subscores were significant difference between 45mg and 90mg dose of nimodipine(P<0.05). The improvement rates were 45,45% of 90mg and 11.11% of 45mg, but there was no significant difference between the 45mg and 90mg dose of nimodipine. 2) The scores of extrapyramidal symptoms and adverse events-somatic symptoms showed a linear decreasing trends over the course of study. 3) The changes in the mean plasma HVA and 5-H1AA concentrations by the dosages and durations of combining of nimodipine were not statistically significant. 4) There was no statistical significance in plasma HVA and 5-HIAA of the improved, non-improved goroup. Nimodipine has a possibility os on adjunctive agent for treatment resistant schizophrenics, elderly patients and liable patients for the Side effects to usual antipsychotic drugs. So we suggest that the dosage of nimodipine must be above 90mg/day in the treatment of schizophrenia.
