Previous studies have shown that five representative behaviors affect the health of adults in everyday life : smoking, drinking, exercise, nutrition, and stress. This study focuses on these five behaviors in an attempt not only to develop a program that promotes health, but also to suggest ways that such a program may be implemented to reflect diverse lifestyles. Our aim is to show how individual subjectivity influences behavior when making lifestyle choices that affect health. By analyzing individual characteristics, we tried to group people according to their common attitude and behaviors to promote health. We hope that this study may provide the fundamental data which may be used to assist professionals in promoting healthy behaviors among adults. In order to examine how subjectivity(e.g, personal opinions or attitudes) influences behavior, we prepared Q-statements which were composed of Q-samples for the study of human subjectivity. We polled forty-two adults and then analyzed the results using a PC qunal program. As a result, the respondents were classed according to six different types. Type One includes people who think managing stress is the most effective way to live a healthy life. They regard smoking and drinking as harmful behaviors. Type Two subjects, on the other hand, regard smoking and drinking as a matter of taste with few harmful effects. Although they recognize the importance of managing stress, they have a positive attitude towards smoking and regard nutrition as a minor factor in promoting their healthy lifestyle. Those classed as Type Three emphasize the necessity of exercise. They perceive drinking, smoking, and stress as harmful. People in this category seek to increase physical strength and to regulate all five health behaviors by keeping them in a normal range. Type Four consists of people who are indifferent to their health. While they seem to recognize the importance of regular exercise, they pay little attention to nutrition or to the harmful effects of smoking, drinking, and stress. They believe that exercise alone is sufficient to maintain their health. Type Five subjects believe drinking is not a harmful behavior at all. Rather. it has a positive effect on their mental health. They are characterized by this positive attitude towards drinking as well as by indifference toward nutrition (although they readily admit that good nutrition is important). Finally. those classed as Type Six have a positive attitude toward moderate drinking as a means to relieve stress. However. they also recognize the harmful effects of excessive drinking. They regard good nutrition as an important lifestyle choice but are indifferent toward exercise. This type is engaged in passive health management. This study devised six types or categories that reflect different attitudes toward promoting health in everyday life. It further went on to analyze the characteristics of each type. This study shows that programs designed to promote health must be modified to reflect the diversity of individual attitudes and patterns of behaviors.

Colorectal cancer remains one of the most widespread malignancies in the world. However, there is a lack of comprehensive studies considering colorectal cancer risk factors among Russian populations, particularly in Siberia. The aim of this investigation was to determine the impact of various lifestyle, dietary, family, and socioeconomical factors on colorectal cancer risk in South-East Siberia. We recruited 185 Russian colorectal cancer cases and 210 gender-, age-, and ethnicity-matched asymptomatic controls with no history of any malignant tumor, using a specially designed questionnaire to obtain relevant information. After the statistical analysis, we defined several significant factors affecting colorectal cancer risk. Among these were smoking (OR=2.13, 95%CI=1.4-3.24, P=0.0004), being overweight (BMI between 25-30, OR=2.45, 95%CI=1.49-4.03, P=0.0004), alcohol drinking (OR=8.73, 95%CI=5.49-13.87, P<0.0001), beer drinking (OR=9.24, 95%CI=5.14-16.61, P<0.0001), consumption of hard liquor (OR=9.37, 95%CI=5.92-14.82, P<0.0001), excessive red meat consumption (P<0.0001), excessive intake of red meat products (P<0.0001), excessive intake of dairy products (P<0.0001), excessive sour cream and cheese consumption (P<0.0001 and 0.0002, respectively), spicy food consumption (OR=2.87, 95%CI=1.9-4.33, P<0.0001), family history of gastrointestinal malignant tumors (OR=3.99, 95%CI=2.09-7.59, P<0.0001), and income exceeding twice the subsistence minimum (OR=5.34, 95%CI=3.35-8.53, P<0.0001). Certain factors, such as high concentration of salt in the food and precancerous colonic lesions, demonstrated borderline significance (OR=3.45, 95%CI=1.68-7.1, P=0.0008, and OR=5.25, 95%CI=1.94-14.22, P=0.001, respectively). Some factors were established as protective, like consumption of rye bread and both rye and wheat bread (OR=0.32, 95%CI=0.21-0.5, P<0,0001, and OR=0.07, 95%CI=0.02-0.21, P<0.0001, respectively), and also low concentration of salt in the food, although this was of borderline significance (OR=0.43, 95%CI=0.26-0.69, P=0.0006). ABO and Rhesus blood antigens were not associated with increased colorectal cancer risk. These results should be definitely applied for elaboration of programs of colorectal cancer prevention in Russia, particularly in Siberia.

본 연구 결과 여성에서의 문제음주와 알코올 의존 비율이 남성보다는 적지만 9.8%로 상당수의 여성들이 알코올 문제를 겪고 있음을 알 수 있었다. 그리고 직장 생활을 하는 여성에서 음주 노출 기회가 더 많고, 실제로 음주에 대한 문제가 더 많이 발생하며 이는 여성의 상태불안과 충동성과 관계가 있다. 여성에서는 직업을 가짐으로써 음주 노출기회가 많아지고 직장 생활에서의 불안 및 충동성이 문제 음주를 일으키는 원인이 될 수 있음을 예상해 볼 수 있겠다. 따라서 직장 여성의 음주 노출 기회와 불안 및 충동성 조절이 음주 위험 요소의 중요한 조절 요인으로 생각된다.

Excessive drinking causes 'alcohol hangover' within 8-16 hours. The cause of 'hangover' has not been elucidated exactly until now, but it is reported that it is caused by the creation of blood ethanol and acetaldehyde as ethanol metabolites. In this study vinegar extract of wood (VE) or OC-1, to which the powder extract of green tea leaves extract is added, was administered to the rats 30 minutes before the oral administration of ethanol (3 g/kg) and the blood ethanol and acetaldehyde concentration was measured in order to evaluate the efficacy of the beverage material for detoxification. As a result, the blood ethanol concentration in the group of the VE-1(vinegar crude extract) and VE-2 (double diluted solution) is statistically lower (P,0.05) than the exclusive alcohol administered control group. The blood acetaldehyde concentration of all groups of VE and OC-2, which is the double dilution of OC-1, is statistically low after 7 hours following ethanol administration. Especially, the AUC value of OC-2 group is statistically low compared to the control group. Accordingly, it indicates the conclusion that VE and OC-1, reducing the blood ethanol and acetaldehyde concentration which are two leading factors of 'hangover' after drinking, and worthwhile to be developed as beverage materials to eliminate 'hangover'.

Performance limiting factors (PLFs) derived from 161 drinking water treatment plants (DWTPs), assessed by International Technical Diagnosis & Assistance Center, were analyzed and evaluated in more detail in this study. In order to conduct study, 161 DWTPs were divided into five categories depending on their capacity, and into twelve groups according to processes and facilities. From the results of analysis, PLFs and their distribution ratio derived from each category were significantly different. Filtration was the most important performance limiting process in all DWTPs of five categories, and the PLFs in filtration were backwashing velocity, media configuration, bed depth, and formation of mud-ball. The PLFs in coagulation-flocculation process were found out to be coagulant dosage, mixing speed, mechanical problems, and others in the order of frequency of occurrence. Also, insufficient disinfection ability that is resulted from insufficient hydraulic detention time and improper chlorine dose and injection point, is the most significant among PLFs in a clear well. In the case of sedimentation, inappropriate baffle structure and excessive upward velocity were PLFs. In addition, the results showed that high turbid water and low alkalinity in a rainy season, ferric and manganese ions, and ammonia nitrogen have been contributed significantly on the performance of DWTPs.

As the concentration of ammonium nitrogen could be reached 2～3 mg/L in the winter in the river. It was clear that the excessive concentration of chlorinated organics could be produced with the increase of chlorine addition to remove ammonium nitrogen. In the innovative ammonium nitrogen removal process, zeolite adsorption is very efficient as substitute for rapid sand filtration without other adverse quality change in the water. This study is conducted to evaluate the feasibility of ammonium nitrogen removal and regeneration by zeolite adsorption in drinking water treatment. Also, the reuse possibility of zeolite is evaluated to change the removal efficiency of ammonium nitrogen through several times of regeneration. The ammonium nitrogen was not removed in sand filter, but it was almost removed in zeolite filter during 7 days. The sand and zeolite filters have a similar result of turbidity removal. Therefore, zeolite filtration was confirmed the removal of turbidity and ammonium nitrogen as a media. When compared KCl with NaCl as a chemical for zeolite regeneration, it is demonstrated that KCl was more efficient than NaCl in the ability of zeolite regeneration. The adsorption rate of ammonium nitrogen was almost not decreased in the results of several times of regeneration. It is indicated that both zeolite and regeneration solution were possible to reuse without variation of regeneration rate through this study.

The river water source of Saidabad Surface Water Treatment Plant at Dhaka, Bangladesh, is deteriorated too much to be treated by conventional treatment process due to excessive ammonia pollution. In order to improve the raw water quality before it enters into the main treatment chain, a pilot study was conducted for pre-treatment of the raw water. The objective is to investigate the rate of reduction of ammonia using the Meteor pilot, a biological pretreatment system, which is a laboratory scale Moving Bed Biofilm Reactor with a nominal volume of hundred liters, filled with 50 L of Meteor 660 media. The reduction of ammonia was quite significant on average 73%, while the reduction of COD was in a range from 20 to 60%. The Meteor pilot was able to treat and nitrify the raw water and produce an effluent that respects the guarantee of ammonia < $4.0mg\;NH_3-N/L$ when the raw water ammonia concentration was < $15mg\;NH_3-N/L$. The study identified operating parameters necessary to achieve the desired goal of adequate ammonia removal. The study results would benefit a range of systems across the country by providing guidance on the design and operation of a biological pre-treatment system for ammonia removal.

Purpose: The purpose of this study was to investigate stress, depression and health risk behaviors in elderly people. Methods: The subjects were 238 Korean elders who had visited the convalescent center. The level of stress was measured by the Korean version of BEPSI, which was developed by Bae, Jeung & Yoo (1992) and modified by Yim et al.(1996). CES-D was used to measure the level of depression. For health risk behaviors, we measured cigarette consumption and alcohol drinking during the last one month. Results: Of the subjects, 17.4% were excessive drinkers and 18.9% were currently smokers. The level of stress was between moderate and high, and 62.7% of the subjects were depressed. There were significant differences in stress and depression according to economic status and self-reported health. In addition, depression had positive correlations with stress and QF score. Conclusion: Stress and depression management programs for the elderly are needed. These findings indicate that nurses must consider stress and alcohol drinking when they take care of depressed elderly people.

This study was carried out to propose the managemental improvement of the purification plants and the distribution facilities which can minimize the formation of disinfection by-products in drinking water distribution system. The disinfection by-products were highly created in the water treatment plant that the organic matters were high and the chlorine dosage was excessive. The concentration of DSPs was shown the highest value in August and the lowest value in December, because of temperature and pre-chlorine dosage effect. From the result of tracer test, the travel time from the treatment plant to the end of pipeline was around 3-4 days in summer, 5-6 days in winter, respectively, and the DSPs concentration of the reservoir(end of pipe) was 2-3 times higher than that of the beginning point. The improvement of the chlorination process and structural reformation of distribution facility was demanded to minimize the DSPs increase from purification plant to the end of pipe.

The Yezo sika deer (Cervus nippon yesoensis) is a subspecies of sika deer originated from Hokkaido, Japan. This paper is a study on the ecological impact caused by large mammals invading the ecosystem. Two pairs of deer were donated to the Agency for Defense Development in Taean in the late 1980s, and the population expanded to over 280 in 2018. The thermal imaging camera showed that the population ranged from 8 to 53 herds, divided into approximately 10 groups. It was confirmed that some of the herds had escaped the management area and invaded the nearby natural ecosystem, causing damage to cultivated land and natural vegetation. Herds of over 50 individuals have been studied in large grassland areas near drinking water sources such as streams and ponds. In places with excessive deer concentration, 1) feeding damage to herbs, shrubs and sub-trees, 2) tree withering due to antler-rubbing, and their habit of migrating along forest edges 3) excessive soil loss on slopes, 4) destruction of herbaceous layers due to compaction, and finally 5) damage to infrastructure were also investigated. As such, it is expected that the results of this study on the ecological and economic damage of Yezo sika deer can be used to predict the impact of other exotic sika deer in South Korea with similar behavioral characteristics and to establish a management plan.
