본 연구는 경주지역 1개 고등학교 3학년 여고생을 대상으로 초경 시작 전인 초등학교 4학년부터 고등학교 2학년까지의 키, 몸무게, 가슴둘레 수치와 초경 연령을 파악하여 여성의 초경이 빠를수록 체성장 속도의 변화가 있을 것이라는 가설을 기초로 두 요인간의 관련성을 파악하고자 시행되었다. 경주시 1개 여자고등학교 3학년생 총 317명에 대해 ㅊ경 나이, 초경시 심리 상태, 초경이 시작되었을 때의 상담 여부와 상담하였던 사람, 부모 신장과 초경전후의 식사 규칙성, 다이어트 경험, 수면시간, 스트레스, 음주/흡연 여부, 질병력 등에 대한 설문 조사를 시행하였고, 초등학교 4학년부터 고등학교 2학년까지의 키, 몸무게, 가슴둘레에 대한 정보는 건강기록부에서 확보하였다. 상기 대상자 중 건강기록부가 분실된 39명, 초경나이에 대해 응답하지 않았던 29명 및 결석 등으로 조사를 하지 못하였던 42명을 제외한 조사 대상자는 206명으로 선정하였다. 대상자들의 초경연령 평균값(Mean±SD)은 13.0±1.11이었고, 초등학교 4학년부터 고등학교 2학년까지의 초경 이후 신장 성장률은 감소하였으며, 초경연령이 빠른 군이 초등학교 때는 신장에 있어서 우위를 차지하나 고등학교에 오면서 신장은 비슷한 수준이 되었다. 초경후 1-2년 사이에 체중과 흉위의 증가율은 감소하였고, 초경연령이 빠른 군이 초등학교와 고등학교 사이에 체중과 흉위에서 모두 우위를 차지하였다. 본 연구의 결과는, 흔히 이차 성징의 시작 시점 혹은 사춘기의 시작 시점으로 보고있는 초경 연령이 청소년기의 성장과 밀접한 관련성이 있고, 특히 체중과 흉위의 성장 속도와 밀접한 관련성이 있음을 시사한다. To understand the onset of menarche in relation to changes in physical growth that take place during female adolescence, especially the changes in height and weight velocity. The 207 senior in one women high school of Kyongju were investigated in April 3 to 8, 2001. We collected the information, relation in the age at menarche, height & weight of parents, regularity of eating, and obesity diet, duration of sleeping, sickness & stress near age at menarche, by self-recording. The status of height, weight & chest circumference between the 4th grade of primary school and the junior of high school was collected by individual Health Record. The results were followed; The average age at menarche was 12.95±1.11 years old and the most frequent age of menarche is 13 years. After menarche, the velocity of height, weight and chest circumference were decreased. The most rapid group of menarche hold dominant position in height during elementary school. As time passed, they dont hold dominant position in height. The most rapid group of menarche get an advantage in the weight and the girth of chest after elementary school. The height of subjects is directly proportional to the height of their parents. These results suggest that the starting age at menestuation can be closely associated with physical growth and development.

Background : Microvascular angina or syndrom X is heterogenous and encompasses different pathogenetic entities. Several studies suggest that microvascular angina have good prognosis and occurs predominantly in postmenopausal women. Lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and fibrinogen are the independent risk factor of acute coronary syndrome and are the chief underlying cause of atherosclerosis. We investigated clinical characteristics and markers in patients with microvascular angina. Methods : We studies 23 patients diagnosed with microvascular angina and 16 control group with negative treadmill exercise test and no significant coronary angiogram. We investigated clinical characteristics in patients group and evaluated symptom during a follow-up period of 4.2± 2.5 month. Exercise time in treadmill exercise test was compared between patients and control group. We assessed the level of markers, such as lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and ESR in two groups. Results : There is no difference in age between two groups. Patients group had a tendency to increase in female, hypertension, DM, and smoking history, but there was no statistical significance difference. Exercise duration time was significantly decreased in patients with microvascular angina (p<0,05). Serum lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholestrol, Triglyceride, ESR, Fibrinogen and Homocystein value were no significant difference between microvascular angina and control group. Only CRP was significantly high in patients with microvascular angina (p<0.05). Conclusion : There was no statistical significance difference in age, sex, hypertension, DM and smoking history between two groups but patients group had a tendency to increase the prevalence in hypertension, DM and smoking history, female. Also, Symptom improvement and disappearance in follow-up was presented in 11 patients of 19(57.9%). Exercise tolerance was worse in patients group than control group. CRP value was significantly higher in patients group than control group. There was no statistical significance difference in lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, ESR and Fibrinogen between two groups.

박근호,정영언,김남석,설수덕,서영옥 東亞大學校 大學院 1999 大學院論文集 Vol.24 No.-

Solution copolymerization of Styrene(St.) with 2-Hydroxypropylacrylate(2-HPA) was carried out with Benzoylperoxide(BPO) as an initiator in toluene at 80℃ in a batch reactor. Reaction volume and reaction time were 0.3 liters, 7hours respectively. The time to reach steady state was about the six time. The monomer reactivity ratios, r1(St.) and r2(2HPS) were determined by both the Kelen-Tudos method and the Fineman-Ross method : r1(St.)=0.376(0.330), r2(2-HPA)=0.408(0.778). The activation energy of thermal decomposition was in range of 33∼55 kcal/mol.

現代 日本語 方言의 諸相 : ム-ド성분인 [そうだ]를 중심으로

박덕수 광주보건대학 1998 論文集 Vol.23 No.-

"Gyena" corresponding to "Souda" is "Gye + Nari," which is noticible for the conception of "a formal noun + a definite auxiliary verb," but is needed to consider the word "Gotoaru." There are "Zeu," "Tzeu," "Tte," and "Tto" derived from "Eungzeu," "Ttoiu," and "Tto." in some different expression methods that have the same meaning as "Souda." Among them, "Eungzeu" is one of auxiliary verbs for conjecture, and "Tto" one of postpositions for quatation. The descriptive auxiliaries of these expression functions for conjecture and quatation a-re also accepted as the conjectural auxiliaries.

Platon 교육사상의 철학적 배경

박덕수 광주보건대학 2004 論文集 Vol.29 No.-

It can be said that it is very important to study Plato's educational thought for understanding the western educational theory. To examine Plato's educational theory, it is also a significant matter to look into how Plato understood the nature of education and what he thought was the purpose of education. I think it a prerequisite to grasp the backgrounds of his educational philosophy in order to understand Plato's educational theory systematically and synthetically. In this point of view, this study examines not only what are the characteristics of Plato's theory of soul, theory of justice and epistemology but also what meanings they have respectively. According to Plato, there are three parts of soul; reason, spirit, and desire. When those play a role individually and are harmonized at the same time, both the ideal of human beings and the purpose of education are achieved. To do so, it is essential to restrict one's desire and do the will with the condition of rational judgement. Those should be righteous, who do not see only the phenomenal world but have cognitive faculty to grasp what the essence of reality is. This philosophy of Plato's is judged to be the starting point of his educational theory. In conclusion, it can be thought to be an important clue for understanding Plato's educational theory to examine into the righteous relationships between soul and body, justice of an individual and a state, and everlasting truth beyond perceiving the phenomenon sensibly.

현대 일본어의 무드 성분 연구 : 「にちがぃなぃ」를 중심으로 Focusing on "Nichigainai"

박덕수 광주보건대학 1996 論文集 Vol.21 No.-

The form of "Nichigainai", which has conjecture with a high probability of being correct, not only encloses the previous sentence, but also has a strong fixedness of meaning based on "A wa B da". There are three kinds of thinking processes or operations with "Nichigainai" in some sentences(basic sentence patterns 2 - 5) which express situations :1 first, a simple conjecture without any clues or prepositions, second, a deductive conjecture to reach a certainty from some prepositions, and third, an inductive conjecture to come to a certainty from some clues or evidences. If the second and the third conjectures are reasonings to get to certainties, the first one can be said to be a conclusive remark on the future rather than a simple conjecture.

日本語の敬語の變化硏究

朴德洙 광주보건대학 2000 論文集 Vol.25 No.-

Honorifics are the language diversely expressed or determind by the realtionship between the speaker and listener, and the social or interpersonal intimacy between them. This study, to find out what are the characteristics of the Japaneses honorific system and how they have currently been varying in their usages, divides the honorifics into three types and then looks into them; subjective, objective, and listener's honorifics, according to the person who should be respected. As to the findings, it is showed that as the modern society became democratic, urbanized, and industrialized, the honorifics of one's position in the past both upon the upper and lower classes have been changed into those of one's social intercourse. It is also examined that the modern sense of honorifics cares to the listener of the counterpart more than the person who is not be with them, which is one of conspicuous characteristics of Japaneses honorifics. Finally, in terms that ″any language must be varied,″ the modern Japanese honorifics han become simple and even confused. But the misuse or abuse of them at the present amy be regarded as the correct honorific style shown into different usages in the future.

포항산 천연 제올라이트와 합성 제올라이트에 의한 금속 이온의 제거

박상윤,장세복,김덕수,김양 濟州大學校 基礎科學硏究所 1996 基礎科學硏究 Vol.9 No.2

국내 경상북도 포항시 남구에서 채취한 4종의 천연 제올라이트를 화학성분 분석, X-선 회절, 열시차분석 실험, 열중량분석 실험으로 분석하였다. 이들 제올라이트의 주성분은 석영, mordenite, heulandite가 함유된 clinoptilolite이었다. NaOH, Ca(OH)₂, HCI 용액으로 처리한 천연 제올라이트의 성질은 X-선 회절법과 열시차분석 실험법으로 연구하였다. 천연 제올라이트와 화학적으로 처리한 제올라이트, 합성 제올라이트를 이용하여 Cu²+, Cd²+, Hg²+, Pb²+, Cr6+등의 중금속 이온과 알칼리 금속 K- 이온의 제거능력을 비교하였고, 중금속 이온 용액의 pH값과 초기농도, 중금속 이온을 제거하는데 소요되는 반응 시간의 효과 등을 비교하였다. 천연 제올라이트에 Ca²+, Pb²+, and Cu²+ 이온용액을 각각 5ppm첨가한 결과 제거율이 94%, 95%, 97%까지 증가되었다. 또한 0.5N NaOH와 0.5 N HCI 용액으로 처리한 매석산 천연 제올라이트를 이용하여 Hg²+ 이온용액을 5ppm 첨가한 결과 제거율이 약 80% 정도였다. 매석산 천연 제올라이트와 합성 제올라이트 A,X 및 Y가 Hg²+ 이온의 최대 제거율을 나타내었다. The four natural zeolites collected in Pohang, Kyungsang buk-do, Korea, were analyzed by means of wet chemical methods, X-ray diffraction, DTA, and TGA. The results indicate that the primary species of those zeolites are clinoptilolite mixed with quartz, mordenite, and heulandite. These zeolites were treated with NaOH, Ca(OH)₂, and HCI solution and their differences were also studied by X-ray diffraction method and differential thermal analysis method. The capabilities of removing heavy metal ions, such as Cu²+, Cd²+, Hg²+, Pb²+ and Cr6+, and alkaline ion, K+ ions with original zeolites, chemically treated zeolites, and synthetic zeolites were compared. The effect of pH value of solution and initial concentration of heavy metal ions, and the effect of reaction time in removing heavy metal ions were ions were studied. The experimental results showed that up to 94%, 95%, and 97% of Ca²+, Pb²+, and Cu²+ ions could be removed, respectively, out of 5 ppm of untreated natural zeolites. About 80% of the Hg²+ ions could be also removed out of 5 ppm Hg²+ ions solution with Maesuk mt. natural zeolite which was treated with 0.5N NaOH and 0.5 N HCI solution. It was found that Maesuk mt. natrual zeolite was most efficient in removing Hg²+ ions compared with the other natural zeolites studied in this work and synthetic zeolite A, X and Y.
