한국은 백 년 이래로 군사적 침략과 경제적 대변혁을 맞았으며, 또한 종교와 문화적 측면에서 전통의 중흥기와 서학의 유입에 대한 문제를 경험하게 되었다. 이런 점에서 한국의 역사적 경험은 주변 국가의 국민들이 배울 만한 의미가 있다고 생각된다. 이와 연관하여 대순진리회가 역사를 계승하고 창신을 이루어나가는 측면의 문제는 정리해볼 만한 가치가 있다. 대순진리회의 종지는 '음양합덕, 신인조화, 해원상생, 도통진경'이다. 특히 대순진리회는 해원상생 사상으로 조화정신을 집중적으로 잘 나타내고 있다. 대순진리회의 해원은 고대 단주로부터의 원을 푸는 것에서 시작되며, 인류가 근본적으로 여러 세대에 걸친 원한을 풀어야만 행복하고 안락한 시대에 진입할 수 있다는 역사관을 보여주고 있다. 대순진리회가 해원을 푸는 방책으로 제시하는 상생은 당시의 갑오동학혁명이나 역사상 많은 종교에서 원한을 해결하는 방법과 구별되는 것이다. 과거에 있어서는 상극의 방법으로 원한을 해결하여 왔으나, 상극의 방식은 오히려 새로운 원한을 더욱 만들어 낼 수 있기 때문에, 현대에 있어 원한을 제거할 수 있는 방법은 악을 선으로써 대하는 것이라고 한다. 증산 성사 및 그 후학들은 사회의 질서를 새롭게 세우는 문제와 전통사회에서 인간 간의 조화를 방해하고 원한을 용인하는 구습을 개조하고 원을 소멸하는 문제에 주의를 기울였다. 이러한 변혁은 평등의 관념을 나타내고 있다. 증산께서는 전 세계적인 관점에서 민족과 국가 그리고 종교 간의 조화를 실현해야 할 것을 강조하셨다. 당시 동아시아 국가는 매우 폐쇄적인 상황에서 서양 국가의 침략을 받던 시기였는데, 증산 성사께서 미래의 세계는 마땅히 화합을 이루고 서로의 장점을 배우는 세계가 될 것임을 예견하셨다는 것은 그의 위대함을 보여주는 대목이다. 증산의 후천개벽사상 역시 조화의 정신을 나타내고 있다. 후천개벽사상은 전통적 참위를 현대적으로 개조한 것으로 민중을 적극적으로 인도하기 위한 것이다. 다음으로, 증산께서는 각 종교에 대해 관용적인 태도를 표하셨고, 또한 매우 진지한 태도로 타 종교로부터 자신이 주창하는 사상과 관련한 자원을 흡수하셨다. 동양의 전통적인 유불선 삼교를 가장 중요한 종교와 문화형태로 인정하시고, 그 삼교의 내용을 두로 포용하셨으며, 심지어 예수교와 서양문화까지 모두 아우르는 태도를 보여주셨다. 서양의 문화 역시 증산께서 추구하시는 신세계의 한 부분이었기 때문이다. 이러한 사실은 증산께서 당시 세계의 역사적 방향에 대해 통찰하고 있었고 이 통찰 속에서 종교 간의 관계가 조화롭게 되어야 함을 주창했음을 말해 준다. 대순사상에는 민간 무교의 내용 역시 풍부하게 들어있다. 부뚜막신, 사명, 아표신, 마장군, 백의군왕, 황천신 등 민간에서 유행했던 다양한 신령숭배의 내용을 흡수했을 뿐만 아니라, 주문과 부를 태우는 법술로 신명과 관련된 내용을 표현하고 있으며, 칠성과 관우의 신앙까지 수용하고 있다. 또한 증산 성사는 동학과 같은 신종교까지 받아들이셨다. 증산께서는 동학혁명의 비참한 최후를 완화시켰던 위대한 역사적 공적을 이루셨으며, 신종교 운동의 사회적 형태를 변화시켰을 뿐 아니라, 서로 다른 내력을 지닌 교도들간의 관계를 조화롭게 하였다. 이로 볼 때 결국 증산께서 주창한 대순사상은 사람들 간의 충돌과 모순을 소멸시키고, 조화와 상생의 사회 환경을 창조하고자 하는 것이었다고 할 수 있다.

Diffusion is a powerful tool to understand geological processes recorded in terrestrial rocks as well as extraterrestrial materials. Since the diffusive exchange of elements or isotopes may have occurred differently in the solar nebula (high temperature and rapid cooling) and on the parent bodies (fluid-assisted thermal metamorphism at relatively low temperature), it is particularly important to model elemental or isotopic diffusion profiles within the mineral grains to better understand the evolution of the early solar system. A numerical model with the finite difference method for the fast grain boundary diffusion was established for the exchange of elements or isotopes between constituent minerals in a closed system. The fast grain boundary diffusion numerical model was applied to 1) ²⁶Mg variation in plagioclase of an amoeboid olivine aggregate (AOA) from a CH chondrite and 2) Fe-Mg interdiffusion between chondrules, AOA, and matrix minerals in a CO chondrite. Equilibrium isotopic fractionation and equilibrium partitioning were also included in the numerical model, based on the assumption that equilibrium can be reached at the interfaces of mineral crystals. The numerical model showed that diffusion profiles observed in chondrite samples likely resulted from the diffusive exchange of elements or isotopes between the constituent minerals. This study also showed that the closure temperature is determined not only by the mineral with the slowest diffusivity in the system, but also strongly depends on the constituent mineral abundances.

After thyroidectomy, some patients who show normal vocal cord movement still complain of subjective voice problems, which could lead to a decrease in quality of life related to communication. This study aims to investigate the effectiveness of a newly designed voice therapy applying neck exercise and semi-occluded vocal tract exercise (SOVTE) to improve voice problems after thyroidectomy without neurological injury. For this purpose, voice therapy was randomly assigned to 10 women who received thyroidectomy. Acoustic analysis [fundamental frequency, jitter, shimmer, noise-to-harmonics ratio, min Voice Range Profile (VRP), max VRP, VRP] was performed before and after surgery and immediately after voice therapy to compare voice changes. The study showed a statistically significant increase in max VRP and VRP after voice therapy compared to before surgery. These results suggest that the voice therapy methods in this study effectively improve a major symptom of voice problems after thyroidectomy, specifically the reduction in the high-frequency range. However, this study was limited in the number of s participants and did not control for the type of surgery. Therefore, further research utilizing larger sample sizes and controlled variables is needed to investigate the long-term effects of voice therapy.

Water samples were collected from three spots(Namcheon, Changwoncheon and Cheongwoonji) in Changwon and genomic DNA was isolated from them. Quantitative PCR was performed with the isolated DNA as template and primers targeting five different class A extended-spectrum beta-lactamase(ESBL) genes(bla_OXA-1, bla_SHV, bla_TEM, bla_CTX-M-1, bla_CTX-M-9). The number of total ESBL genes from each sample showed large variations between each sample. Thirty nanograms of DNA from Namcheon contained 1.93×10⁶ copies of ESBL genes whereas the same amount of DNA from Changwoncheon contained 1.47×10⁵ copies of ESBL genes. However, the same amount of DNA from Cheongwoonji pond contained only 9.5×10³ copies of ESBL genes. The ratio of each ESBL genes showed little difference between Namcheon river and Changwoncheon river, but DNA from Cheongwoonji pond showed a large difference from the rest. bla_OXA-1 gene was present at 65.3%, and bla_CTX-M-1 gene 33.6% for Namcheon comprising together almost 99%. bla_OXA-1 gene was present at 64.1%, and bla_CTX-M-1 gene 19.1% for Changwoncheon comprising together over 83%. bla_CTX-M-1 gene was present at 87.5% and bla_CTX-M-9 genes 9.8% for Cheongwoonji, a pond which is a closed and isolated environment.

Sulcus vocalis is characterized by incomplete closure of the vocal folds, with a high mean airflow rate (MFR) as a distinctive feature. The MFR is measured using two aerodynamic analysis methods [the maximum sustained phonation protocol (MXPH) and voicing efficiency protocol (VOEF)] of the phonatory aerodynamic system (PAS), and the results may vary depending on the method. This study compared the differences in MFR before and after treatment (microsurgery and voice therapy) according to the MXPH and VOEF of the PAS in 30 patients with sulcus vocalis. Additionally, we examined whether there were differences in the subjective voice evaluation (voice handicap index, VHI), perceptual voice evaluation (GRBS), and fundamental frequency (F0) before and after treatment. The results showed significant differences between the two methods, both before and after treatment, in patients with sulcus vocalis. However, there were no significant differences by methods in the changes before and after treatment. The VHI and GRBS scores significantly decreased after treatment; however, F0 showed no significant differences before and after treatment. This study indicates that when evaluating MFR changes in patients with sulcus vocalis, it is acceptable to use either aerodynamic analysis (MXPH or VOEF).

This study analyzes previous research on 'The Self-Governance of the Commons' to overcome 'The Tragedy of the Commons', and derives elements for successful commons management. These factors are compared and analyzed with the social and economic attributes of the Jeju Haenyeo community, a successful community self-governance model. In addition, in the recently changing environment, it is revealed whether this internal community mechanism can be useful in the future. The goal is to reveal what social and economic factors will help the sustainability of the Jeju haenyeo community in the future. As a result of analyzing the internal operating mechanism of the Jeju haenyeo community, the production and distribution system that improves trust and reciprocity, the inherent sense of community, the division of roles between formal and informal organizations, and the institutionalized explicit and implicit norms within the organization served as internal and external strengths of community sustainability. However, the closure of the network, the crisis of productivity, the weakening of homogeneity, and the emergence of new subjects acted as internal and external weaknesses. In conclusion, for the sustainability of the Jeju Haenyeo community, it is necessary to reorganize the reproductive function of labor using the haenyeo school, to maintain clarity on the subject of livelihood and cultural transmission, and guarantee the income of Haenyeo.

Greenhouse soil cultivated with excessive compost and chemical fertilizer has been an issue to deteriorate soil and water quality in the environment. The objective of this study was to evaluate the nutrient outflow by desalting method, flooding soil surface, after vegetable cropping in greenhouse soils. Field experiment from July to September 2008, was conducted to quantify greenhouse locations, i.e. alluvial plain and local valley. The changes of desalinization in both locations were higher as the amounts of irrigated and drained water were increased. Particularly, the ratio of desalinization in alluvial plain was much higher (66.7%) than the one in local valley (45.6%). However, $NH_4$-N contents of local valley soil during the flooding were higher than in those of alluvial plain. This was caused by high total nitrogen and organic matter in local valley soil than those in alluvial plain soil. With comparing to the input and output loads of T-N and T-P in greenhouses with local valley and alluvial plain soils, the output loads of nutrients were larger than the input loads of nutrients. This result showed that the flooding soil surface can be a good treatment to desalinize greenhouse soils. However, this conclusion remained that the flooding water containing high N and P concentrations might cause the secondary effect on the quality of streams and groundwater since excessive nutrient concentrations can be the main cause of eutrophication problem in aquatic environment.

The present study was conducted to investigate smoking status and the relationship of smoking to hypertension and diseases on 1,504 subjects who were over 30-year-old age in Kyungsan Gun, Kyungpook province, during the period of 12 months from March 1978 to February 1979. The results obtained are summarized as follows: Of 1,504 subjects, 52.2 percent smoked. The percentage of males smoking showed 84.8 and the percentage of females was 30.7. There were no statistically significant differences between the rate of smoking and educational levels. Protestants demonstrated lower rates of smoking compared with other groups. Regarding the age started to smoke, 66.4 precent of male smokers and 16.9 percent of female smokers commenced smoking before the age of 19. In the regard to the average number of cigarettes smoked daily, 45.8 percent of male smokers consumed some 20 cigarettes and 24.1 percent of female smokers consumed some 10 cigarettes. 3.2 percent of male smellers smoked 40 or more cigarettes a day. Alcohol consumption was closely associated with smoking. 90.7 percent of male alcohol drinkers and 60.1 percent of female drinkers smoked. Cigarette smokers have higher rates of ailments than nonsmokers as a whole. The complaints of cough with sputum and shortness of breath revealed higher rates among smokers than among nonsmokers. Frequency of illnesses showed higher for smokers than for nonsmokers. Smokers were more likely than nonsmokers to suffer from chronic obstructive lung diseases such as chronic bronchitis, asthma, and emphysema. Abnormal systolic blood pressure (>160mmHg) and diastolic (>100) revealed significantly higher among smokers than among nonsmokers.

The purpose of this investigation were to evaluate facial vortical changes occurring in patients treated orthodontically with first premolar, second remolar and second molar extractions : to compare these changes with those occurring in patients treated orthodontically without extractions : and finally, to evaluate the effects of extractions in facial vortical changes. Cephalometric records of 50 male & female nonextraction patients and 88 male & female extraction patients were obtained from the department of orthodontics at Chosun University, College of Dentistry. The second molar fully erupted pPatients to have little variation according to growth were chosen as the sample for this investigation. For comparisons, the samples of 88 male & female extraction patients were subdivided into 42 first premolar extraction, 24 second premolar extraction, and 22 second molar extraction patients. Fourteen cephalometric measurements were selected to examine whether orthodontic extraction treatment led to vertical changes or not. The pretreatment and posttreatment lateral cephalographs were taken on the same radiographic unit. $SPSS/PC^+$ statistical program was used to compare and to analyze the changes between 'before & after' orthodontic treatment. The results of this study were as follows. 1. There were no statistical significances in any cephalometric measurements between 'before & after' orthodontic treatment regardless of orthodontic extractions for each group. 2. On average, the upper 6 to palatal Plane and the lower 6 to mandibular plane after orthodontic treatment were increased in all group. This means most of orthodontic mechanics are extrusive in nature. Especially, in orthodontic extraction. cases, it may be caused by orthodontic mechanics for space closure and alignments. 3. On average, in the second molar extraction group, the facial vertical dimension was increased after orthodontic treatment. It nay be induced as a result of moving the molars distally to gain enough space to correct the molar relationship and to simultaneously improve the deep bite. 4. There was no statistical significance between orthodontic extractions and facial vertical changes. This means that orthodontic extractions have no influence on facial vortical changes. 5. The cephalometric measurements with statistical significance in ficial vertical changes for each group were PP-MP, Op-MP, $\underline{1}$ to PP and $\overline{1}$ to MP.

Background: The incidence of chronic obstructive pulmonary disease (COPD) is increasing and the disease is becoming an important cause of morbidity and mortality worldwide. It is important to implement evidence-based guidelines by primary care physicians (PCPs) to establish qualified management of COPD patients. The aim of this survey is to investigate the pattern of COPD management among PCPs and to apply it to the development of Korean COPD guidelines. Methods: A web-based questionnaire was prepared that consisted of 25 questions on the pattern of COPD management. A total of 217 PCPs participated in the survey from June 2006 to May 2007. Results: Many PCPs (61.8%) possessed a spirometer, but the application rate was relatively low (35.8%) and more than half of the COPD patients (57%) did not receive a diagnosis based on spirometry. Administration of oral medication was preferred than the administration of inhaled medication for both stable COPD and acutely exacerbated COPD. More than 90% of the PCPs endorsed educational measures to quit smoking and vaccinate against influenza. It was noted that 56.7% of the PCPs were aware of the GOLD guidelines, but only 7.3% tended to fully implement the recommendations of the guidelines in daily practice. Conclusion: The results of the survey indicate that despite the high awareness rate of the current COPD guidelines, deficits exist among the PCPs with respect to the diagnosis and treatment of COPD. The results of this survey should be applied for the development of new COPD guidelines in order to decrease the discrepancy between the guidelines and the daily practice of the PCPs.
