A STUDY OF THE HISTORICAL EARTHQUAKE CATALOG AND GUTENBERG-RICHTER PARAMETER VALUES OF THE KOREAN PENINSULA

Seo, Jeong-Moon,Choi, In-Kil,Rhee, Hyun-Me Korean Nuclear Society 2010 Nuclear Engineering and Technology Vol.42 No.1

The KIER's Korean historical earthquake catalog was revised for MMI${\geq}$VI events recorded from the years 27 A.D. to 1904. the magnitude of each event was directly determined from the criteria suggested by Seo. The criteria incorporated the damage phenomena of the Japanese historical earthquake catalog, recent seismological studies, and the results of tests performed on ancient structures in Korea. Thus, the uncertainty of the magnitudes of the Korean historical earthquakes can be reduced. Also, the Gutenberg-Richter parameter values were estimated based on the revised catalog of this study. It was determined that the magnitudes of a maximum inland and minimum offshore event were approximately 6.3 and 6.5, respectively. The Gutenberg-Richter parameter pairs of the historical earthquake catalog were estimated to be a=5.32${\pm}$0.21, b=0.95${\pm}$0.19, which were somewhat lower than those obtained from recent complete instrumental earthquakes. No apparent change in the Gutenberg-Richter parameter is observed for the $16^{th}-17^{th}$ centuries of the seismically active period.

Crossing the Wilderness: The Meaning of Toil in Hemingway's “Big Two Hearted River” and McCarthy’s All the Pretty Horses

( Seo¸ Ju-hyun ) 동국대학교 영어권문화연구소 2016 영어권문화연구 Vol.9 No.3

Although Hemingway's short story “Big Two Hearted River” was not popular during that period, it has literary themes that are central to Hemingway and has a strong sense of his typical writing style, the iceberg technique. Therefore, his seemingly simple and short story of Nick Adams should not be underestimated as an account of a peaceful journey toward nature. On the contrary, it is a story of an inwardly and outwardly wounded soldier from the First World War. Hemingway himself also took part in the same war and was traumatized by the event. Cormac McCarthy also examines the anxieties of modern people in his writing by using similar iceberg technique. For this reason, his novel All the Pretty Horses should not be considered as another old-fashioned Western adventure story. As Nick Adams in “Big Two Hearted River”, John Grady Cole is a victim of the World War. John Grady Cole’s father participated the Second World War and he lost his Wille zum Leben. Ultimately, his father’s participation leads John’s entire family to be torn apart. After the death of John Grady Cole’s maternal grandfather, he leaves United States for Mexico in order to keep his cowboy lifestyle and spirit. This paper aims to compare two stories, “Big Two Hearted River” and All the Pretty Horses, so as to show personal journey and toil in the wilderness as a means of self-redemption and regaining one’s authentic identity in a disoriented modern world. To examine the meaning of journey toward the wilderness, it is important to remember that there are two different aspects in American Wilderness. First, it has the qualities of solitude and hardship. Second, it is an attractive place to city dwellers who want to escape from too much civilization. In this perspective, I will explore the possibility of the two protagonists’ endeavors at healing their damaged identities in the wilderness. This paper will be divided into three main parts. First, I will examine the departures of the two protagonists toward the wilderness. Second, I will discuss the effects of their endeavors in the wilderness. Lastly, I will explore their gradual realization of the reality and constant exertions to regain control over their authentic identities and values. This comparison process will give the readers the idea that the protagonists’ patient labors and toils in crossing the wilderness can be read as efforts to restore their impaired subjecthood in a post-war world. Even though the two protagonists’ endeavors to heal their identities in it are not successfully fulfilled, it would be worthwhile to analyze some positive aspects of their attempts as our contemporaries’ heroic challenge.

초등학교 5,6학년의 경험적 내러티브 분석 연구 -학급 내 발표 상황에서 생성된 담화를 중심으로-

서현석 ( Hyun Seok Seo ) 청람어문교육학회(구 청람어문학회) 2015 청람어문교육 Vol.56 No.-

이 연구의 목적은 초등학교 5·6학년 학생의 경험적 내러티브 담화를 분석하고, 양적·질적인 면에서 해석함으로써 교육적 시사점을 모색하는 것이다. 연구의 목적을 이루기 위해 연구자는 경험적 내러티브가 지니는 초등교육, 국어 교육, 인성 교육적 측면에서의 의의를 고찰하였다. 그리고 서울, 경기, 대구 등 세 개 지역의 5,6학년이 생성한 내러티브 담화를 수집하였다. 최종 선정된 104개의 담화를 분석한 결과, 학급 내 발표 상황에서 5·6학년 학습자의 경험적 내러티브 평균 발화 시간은 36.87(초)이 었으며, 내러티브 당 에피소드는 평균 1.9개, 평균 2.34개의 문장과 4.26개의 C-unit을 포함하였다. 경험적 내러티브 구조의 발달 수준은 평균 3.84(SD=1.791)로 분석되었다. 5·6학년의 경험적 내러티브 담화를 서현석 외(2013)에서 분석한 1·2학년의 경험적 내러티브 담화와 비교한 결과는 다음과 같다. 첫째, 5·6학년의 경험적 내러티브에서 좀 더 많은 부가 관계의 말하기 양상이 포착되었다. 이는 인과관계를 효과적으로 구사하여 내러티브를 구성하는 능숙한 화자의 말하기로 볼 수 없는 것이다. 둘째, 5·6학년 학습자의 경험적 내러티브의 구조 발달 수준은 1·2학년의 경험적 내러티브 구조의 발달 수준(평균 5.39 /SD=1.743)보다 낮은 것으로 분석되었다. 이러한 결과는 학년이 올라갈수록 점차 늘어나는 학습량을 일정한 수업 시간 내에 다루어야 하기에 좀 더 교사 중심적인 수업이 되는 것과 관련이 있다고 해석할 수 있다. 즉, 5·6학년 학생들은 진정한 자기표현이 기회 대신에 자신의 경험과 멀어지는 추상적인 학습 내용에 집중하게 되어 오히려 1·2학 년의 경험적 내러티브 구조 발달 수준보다 낮은 수준을 보였다. Purpose of this study is analyzing personal narrative discourse of elementary fifth and sixth graders and seeking educative implication by interpreting quantitative and qualitative side. To achieve purpose of this study, researcher considers personal narrative’s meaning on aspect of elementary education, Korean language education and character education. Researcher also analyzes 104 narrative discourses generated from elementary fifth and sixth graders of Seoul, Gyeonggi, Daegu. The analysis shows that at presenting context in class, the average speaking time of the learner’s personal narrative is 36.87 seconds and the average number of the stories per one narrative is 1.9. It also includes 2.34 sentences and 4.26 C-units on average. And the level of development of personal narrative structure is 3.84(SD = 1.791) on average. Researcher compares the fifth and sixth grader’s personal narrative discourse with the first and second grader’s analyzed by Seo, Hyun-Seok et al(2013). First of all, in the fifth and sixth grader’s personal narrative, more modes of telling with additive relation are detected. This is rather far from telling of skillful narrator that constructs narrative by expressing causal relation efficiently. Secondly, the fifth and sixth learner’s level of development of personal narrative structure is analyzed lower than the first and second learner’s(5.39 on average /SD=1.743). This result shows that the higher grade students move, the more teacher-centered class is. Because more quantity of learning must be treated in fixed class hour. In other words, the fifth and sixth students concentrate abstract learning contents instead of true self-expression. This rather influences the result that the fifth and sixth learner’s level of personal narrative fulfillment is lower than the first and second learner``s.

토마토 ‘모모타로’를 공시하여 셀레늄 10㎎ㆍL?¹의 관주 및 엽면시비 등의 단용 및 혼용처리가 수경재배 토마토의 생육 및 과실 내 셀레늄 축적 함량에 미치는 영향을 구명하였다. 토마토 종자를 50공 트레이에 파종하여 70일 동안 육묘한 후 유묘를 코코피트 슬라이브를 이용한 수경재배 시스템에 정식하였다. 양액은 일본원예시험장 배양액 표준처방으로 조성하였으며, pH 5.8~6.2와 EC 2.3 ㎎ㆍL?¹ 등으로 조절하여 공급하였다. 셀레늄은 무기태 SeO₂와 sugar fatty acid ester에 킬레이트화 한 유기태 셀레늄을 10 ㎎ㆍL?¹으로 조성하여 관주, 엽면시비, 관주와 엽면시비를 병행하여 처리하였다. 초장, 엽수, 엽면적 및 엽록소 등의 토마토 생장반응은 셀레늄의 엽면시비, 그리고 엽면시비와 관주를 병행한 처리구에서 현저히 증가하였다. 과실 내 셀레늄 축적 함량은 킬레이트화 한 유기태 셀레늄을 엽면시비와 관주를 병행하여 처리한 경우에 0.302 ㎎ㆍL?¹으로 가장 높았다. 무기태와 유기태 셀레늄의 엽면시비와 관주 등의 단용 처리 보다는 혼용 처리가 전반적인 과실 생장과 체내 셀레늄 축적에 효과적이었다. 무기태 설레늄(SeO₂) 보다는 sugar fatty acid ester에 킬레이트화한 유기태 셀레늄 처리가 셀레늄을 함유한 기능성 토마토의 수경재배에 더 효과적이었다. This study was conducted to clarify the effects of supplying methods of selenium on the growth and Se uptake of hydroponically grown tomato plants. Tomato seeds (Lycopersicum esculentum Mill. cv. Momotaro T-93, Daki Seed Co.) were sown in plug tray with fifty holes, and raised for sixty days. Tomato seedlings transplanted to coco fiber slabs were supplied with the nutrient solutions adjusted to EC 2.3 dSㆍm?¹ and pH 5.8~6.2 recommended by the Japanese Horticultural Experiment Station. Selenium forms used were inorganic SeO₂ (here in after referred to Se) and organic selenium chelated with sugar fatty acid ester (here in after referred to chelated-Se). 10 ppm selenium solutions were treated to tomato plants with foliar applications, drenching, and foliar application plus drenching. Growth characteristics in terms of plant height, number of leaves, leaf area and chlorophyll content were significantly increased in the plot of foliar application of Se, and in the plot of foliar application plus drenching of chelated-Se than other plots, respectively. Transported contents of selenium into the tomato fruits were highest as 0.302 ppm in the plot of foliar application plus drenching of chelated-Se. Also, it had tended to be higher in the plot of foliar application plus drenching than in the plots of foliar application or drenching in both of Se and chelated-Se. Foliar application and drenching of organic chelated-Se were effective to produce the functional tomato fruits.

Cognitive decline is perceived to be a characteristic of the aging process, and is profoundly manifested in age-related neurodegenerative disorders such as Aizheimer's Disease(AD). The pathologic mechanisms underlying neurodegeneration are complex and not completely understood, but a contributing factor is believed to be oxidative stress. The brain has a high metabolic requirement for oxygen and a high concentration of polyunsaturated fatty acids, and therefore is prone to lipid peroxidation. Lipid peroxidation leads to the production of free radicals that may attack and irreversibly damage neural tissue, thus contributing directly or synergistically to neurodegenerative process. Accumulating evidence from preclinical and clinical studies supports the hypothesis that oxidative stress may be associated with the onset and progression of AD. Antioxident therapies are being promoted in the lay press to enhance mental functions and delay cognitive losses with aging. This paper summarizes the oxidative stress hypothesis of AD and reviews the strengths and limitations of published antioxidant studies in AD in relation to the role of such therapies in practice.

事業部制下의 豫算編成過程에 관한 硏究 : 二元的 管理構造로부터의 接近 An Approach to the Dual Structure of Budgeting

徐賢珍 제주대학교 1990 논문집 Vol.30 No.1

As organzations grow, top management faces two contuinuing problems: a) how to divide activities and responsbilities, and b) how to coordinate subunits. Inevitably, the centralized management system based on functional organization in genernal has been changed to a decentralized management system, the authority to make decisions is distributed among subunits' managers. The decentralized management system engages a divisional organization which is managed by profit centers, because profit centers are useful to division managers who are reponsible to the division's performance in both revenues and expenses. The specific incentives for introducing the divisional organization system based on profit centers are information specialization, timeliness of response, conservation of central management's time and training and motivation for managers of each division. This study reviews the budgeting process of the management system employing divisional organization. As the mangement subunits of divisional organizations are separated from both head office and other divisions, a budgeting process is characterized by a dual structure. Therefore, the major function of a budgeting process in a divisional organization is to coordinate management subunits including the head office and it's divisions and to motivate division managers. First of all, the basic assumptions for preparing the budget under divisional organizations include the following: 1) identification of the relationships of authority between the head office and the divisions 2) performance appraisal of divisions 3) cost allocations of comon costs, for exemple, head office expenditures 4) intra-company transfer pricing methods 5) preparation of the budget manual 6) establishment of an accounting system applicable to divisional organization and etc. Let us look more closely at the budgeting process of the head office and divisions: (1) the budgeting process of the head office First, the head office must establish a comprehensive profit plan and the overall budget manual. The former refers to top management's business targets for the comming year and the latter, a standard for preparing each division's budget. In preparing the master budget, the head office's budget must first be prepared to include both the managerial department and the service department. Then, divisions' budgets and head office budgets are meshed. The budget committee is participated in by controllers and/or division managers who discuss and coordinate to arrive at a synthesized master budget. Top management determines the final master budget. (2) the budgeting process of divisions For preparing divisons' budgets, division managers must establish a profit plan and a budget manual within the division based on the comprehensive profit plan and the overall budget manual. Subunits of the divisions, for example functional departments, must prepare their departments' budgets based on the divisional budget manual. After depatments' budgets are meshed, the bdudget committee and the budget staff of the division discuss the bdudget. Division managers decide division budgets independently.

Lipomyces starkeyi KSM 22 glucanhydrolase 함유 구강세정액의 치태 억제 효과

서은주,정현주,김도만,김상혁 전남대학교 치의학연구소 2003 구강과학 Vol.15 No.3

A novel glucanhydrolase from Lipomyces starkeyi KSM 22 has been suggested as a promising anti-plaque agent because it has been shown to have additional amylase activity and mutanase activity besides dextranase activity and to strongly bind to hydroxyapatite. Mouthrinsing with Lipomyces starkeyi KSM 22 glucanhydrolase solution was comparable to 0.12% chlorhexidine mouthwash in inhibition of plaque accumulation and gingival inflammation and local side effects were less frequent and less intense in human experimental gingivitis. In this study, Lipomyces starkeyi KSM 22 glucanhydrolase mouthrinses (1 and 2 unit/ml) were compared with a control mouthrinse (commercial 0.01% benzethonium chloride mouthrinse, Caregargle^(�), Hanmi Pharmaceuticals) in the ability to inhibit on plaque formation. A 3-replicate clinical trial using 4-day plaque regrowth model was used. Fifteen volunteers were rendered plaque-free on the 1st day of each study period, ceased toothcleansing, and rinsed 2X daily with allocated mouthrinse thereafter. On day 5, plaque accumulation was scored and the washout periods was 9 days for the next trial. Lipomyces starkeyi KSM 22 glucanhydrolase(1 unit and 2 unit)- containing mouthrinse resulted in significantly lower plaque formation in plaque area and thickness, compared to the control mouthrinse. There was no significant difference in plaque inhibition between enzyme-mouthrinses at 2 different concentrations used. This glucanhydrolase-containing mouthwash resulted in significantly lower plaque area severity index score and tended to have lower plaque thickness severity index score than those of control mouthrinse. But there was no significant difference according to the enzyme concentration. From these results, Lipomyces starkeyi KSM 22 glucanhydrolase-containing mouthrinse has greater inhibitory effect of plaque formation than commercial mouthrinse alone. Therefore, this glucanhydrolase preparation is a promising agent for new mouthwash formulation in the near future.
