The diagnostic requirements were suggested and explained regarding the systems of differentiation of symptoms and signs in the second year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows; - differential diagnosis according to condition of body fluid, differentiation of syndromes according to the state of qi and blood, differential diagnosis according to relative excessiveness or deficiency of yin and yang(氣血陰陽津液辨證) - differentiation of diseases according to pathological changes of the viscera and their interrelation - analyzing and differentiating of febrile diseases in accordance with the theory of the six channels(傷寒辨證) The individual diagnosis pattern was arranged by the diagnostic requirements in the following order : another name(異名), notion of diagnosis pattern, index of differentiation of symptoms and signs(辨證指標), the main point of diagnosis, analysis of diagnosis pattern(證候分析), discrimination of diagnosis pattern(證候鑑別), a way of curing a diseases(治法), prescription(處方), herb in common use(常用藥物), diseases appearing the diagnosis pattern(常見疾病), documents(文獻調査). This study was carried out on the basis of the Chinese documents and references.

본 연구는 상악 제1대구치에 발치공간 폐쇄를 위한 근심력 적용시, 대구치의 근원심 경사도와 회전정도의 변화가 치근막의 응력분포와 치근막 내에서의 초기 치아이동에 어떤 변화를 야기하는지를 살펴보기 위하여 시행되었다. 상악 제1대구치와 치근막의 3차원 유한요소모델을 제작하여 20˚의 근심경사와 원심경사를 설정하고. 20˚의 근심회전과 원심회전을 설정하였다. 각각의 상황에서 치체이동을 유도하는 근심력을 가하기 위해 협면에 rigid element를 부착하고 200g의 근심력과 9:1의 countertipping 모멘트. 5:1의 counterrotation 모멘트를 부여하였다. 각각의 응력분포 및 초기이동 양상을 비교하여 다음과 같은 결론을 얻었다. 상악 제1대구치의 경사도 변화나 회전 변화를 통해 근심력 적용시 구치의 근심이동에 대한 저항의 증가를 얻을 수 없었다. 20˚의 근심경사와 20˚의 원심회전이 매우 유사한 응력분포 및 변위를 나타내었다. 20˚의 원심경사와 20˚의 근심회전도 마찬가지로 유사성을 보였다. 20˚ 근심경사 및 20˚ 원심회전된 경우 치근이 협측 아동하고 치관이 설측 이동하는 관상면 상에서의 회전경향이 발생하였다. 20˚ 원심경사 및 20˚ 근심회전된 경우 치근이 설측 이동하고, 치관이 협측 이동하는 관상면 상에서의 회전경향이 발생하였다. 경사되거나 회전된 치아에 근심력을 가해야 할 경우, 관상면상에서의 회전을 방지하기 위한 부가적인 토크 조절이 필요하다. The purpose of this study was to evaluate the stress distributions at the periodontal ligament (PDL) and displacements of the maxillary first molar when mesially directed force was applied under various molar angulations and rotations. A three dimensional finite element model of the maxillary first molar and its periodontal ligament was made. Upright position, mesially angulated position by 20˚ and distally angulated position of the same degree were simulated to investigate the effect of molar angulation. An anteriorly directed force of 200g, countertipping moment of 1,800gm-mm (9:1 moment/force ratio) and counterrotation moment of 1,000gm-mm (5:1 moment/force ratio) were applied In each situation. To evaluate the effect of molar rotation on the stress distribution, mesial-in rotation by 20˚ and the same amount of distal-in rotation were simulated. The same force and moments were applied in each situation. The results were as follows: In all situations, there was no significant difference in mesially directed tooth displacement. Also, any differences in stress distributions could not be found, in other words, there were no different mesial movements. Stress distributions and tooth displacement of the 20˚ mesially angulated situation were very similar with those of the 20° distal-in rotated situation. The same phenomenon was obserned between the 20° distally angulated situation and 20˚ mesial-In rotated situation. When the tooth was mesially angulated, or distal-in rotated, mesially directed force made the tooth rotate In the coronal plane, with its roots moving buccally, and Its crown moving lingually. When the tooth was distally angulated, or mesial-in rotated, mesially directed force made the tooth rotate in the coronal plane, with its roots moving lingually, and its crown moving buccally. When force Is applied to an angulated or rotated molar, the orthodontist should understand that additional torque control is needed to prevent unwanted tooth rotation in the coronal plane.

Silicon-to-silicon anodic bonding was accomplished using lithium doped interlayer. Lithium doped interlayers were deposited on silicon substrates by electron beam evaporation, which has a fast deposition rate compared with sputtering method. Silicon-to-silicon bonding occurs in the range of temperatures from 250℃ to 300℃ with the applied voltages from 70V_(DC) to 100V_(DC). The bonding strength obtained from tensile test was about 5MPa under the condition of 80V_(DC) in 300℃. The surface morphology of lithium doped interlayer was studied with the atomic force microscopy (AFM). Finally, secondary ion mass spectroscopy (SIMS) analysis was carried out in order to investigate the role of the lithium ions in bonding mechanism.

본 연구는 부산지역의 주요기업 변화를 살펴보기 위해 매출액 기준 전국 상위 1,000대 기업에 속하는 부산기업을 조사하여 비교분석을 실시하였다. 분석결과 2005년에 전국 1,000대 기업 중 46개 기업이 부산에 소재하였는데, 2019년에는 12 개가 줄어든 34개 기업만이 전국 1,000대 기업에 포함되었다. 또한, 전국 상위 1,000대 기업의 매출액 기준으로 부산지역 기업의 매출액 비중은 2005년 1.6%에서 2019년 1.4%로 줄어든 것으 로 나타났다. 이는 수도권 집중현상이 점차 강화되고 있기 때문이다. 한편, 부산지역 매출액 기준 상위 10대 기업은 많은 변화가 있었는데, 2005년 상위 10대 기업 중 2019년에도 상위 10대 기 업에 포함된 기업은 ㈜한진중공업, 르노삼성자동차(주), ㈜부산은행, ㈜서원유통 등 4개뿐인 것 으로 나타났다. 통계적 인과 관계는 확정할 수 없으나 지역 대기업의 쇠퇴 및 유출과 지역의 쇠퇴가 동시에 이루어지고 있어 지역 경제의 침체와 대기업의 쇠퇴 및 유출이 상당한 관계가 있음을 유추해 볼 수 있다. 특히 2011년 이후 지역 주력 제조업 기업들이 1000대 기업 진입에 실패하였다는 점을 주목해 볼 필요가 있다. 지역 제조업 대기업의 이탈 또는 쇠퇴는 지역 생산성 하락에 영향을 미 쳤을 가능성이 높고, 낮아진 지역 산업 생산성이 지역 경제성장률 둔화에도 영향을 미칠 가능성 이 있다. 따라서 지역의 경제활력 저하 문제를 제고하기 위해서는 지역 산업구조 개편 문제와 생 산성 향상 방안에 대한 고민이 필요하다.

As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions
