<▼1><P><B>Significance</B></P><P>Leaf senescence is regulated in a complex manner, involving time-dependent interactions with developmental and environmental signals. Genetic screens have identified key regulators of senescence, particularly late-stage senescence regulators. Recently, time-course gene-expression and network analyses, mostly analyses of static networks, have predicted many senescence regulators. However, senescence is defined by time-evolving networks, involving the temporal transition of interactions among senescence regulators. Here, we present time-evolving networks of NAM/ATAF/CUC (NAC) transcription factors, central regulators of leaf senescence in <I>Arabidopsis</I>, via time-course gene-expression analysis of NACs in their mutants. These time-evolving networks revealed a unique regulatory module of NACs that controls the timely induction of senescence-promoting processes at a presenescent stage of leaf aging.</P></▼1><▼2><P>Senescence is controlled by time-evolving networks that describe the temporal transition of interactions among senescence regulators. Here, we present time-evolving networks for NAM/ATAF/CUC (NAC) transcription factors in <I>Arabidopsis</I> during leaf aging. The most evident characteristic of these time-dependent networks was a shift from positive to negative regulation among NACs at a presenescent stage. ANAC017, ANAC082, and ANAC090, referred to as a “NAC troika,” govern the positive-to-negative regulatory shift. Knockout of the NAC troika accelerated senescence and the induction of other <I>NAC</I>s, whereas overexpression of the NAC troika had the opposite effects. Transcriptome and molecular analyses revealed shared suppression of senescence-promoting processes by the NAC troika, including salicylic acid (SA) and reactive oxygen species (ROS) responses, but with predominant regulation of SA and ROS responses by ANAC090 and ANAC017, respectively. Our time-evolving networks provide a unique regulatory module of presenescent repressors that direct the timely induction of senescence-promoting processes at the presenescent stage of leaf aging.</P></▼2>

박은영 ( Eun Young Park ),이은남 ( Eun Nam Lee ),강지연 ( Ji Yeon Kang ),주현옥 ( Hyeon Ok Ju ),김삼숙 ( Sam Sook Kim ),최은정 ( Eun Jung Choi ),김학선 ( Hack Sun Kim ) 경희대학교 동서의학연구소 2011 동서간호학연구지 Vol.17 No.1

보완대체의학은 건강증진과 질병예방을 위한 총체적인 접근법의 하나로 환자뿐 아니라 일반인들 사이에서도 이용률이 증가하고 있고, 교육에 있어서도 보완대체요법 관련 교과목을 의학이나 간호학의 정규 교과과정 내에 포함시키는 대학이 늘어남에 따라 미래의 건강관리 제공자인 간호학생들의 보완대체의학에 대한 인식이나 태도를 파악하는 것은 중요하다. 이에 본 연구는 Q방법론을 이용하여 보완대체의학에 대한 간호학생의 반응을 유형화하고 구체적인 특성을 파악하고자 시도되었다. 보완대체의학에 대한 간호학생의 반응은 4개로 유형화되었으며, 각 유형은 실용적 확신형, 견제형, 가치 인정형, 제한적 수용형으로 명명하였다. 각 유형의 명명에서 볼 수 있듯이 간호학생들은 인식에서 약간씩은 차이가 있지만 보완대 체의학에 대해 비교적 긍정적인 태도를 갖고 있는 것으로 나타났다. 이러한 결과는 간호학생들이 보완대체요법에 대해 긍정적인 태도를 보였음을 보고한 Kim (2004), Kim, Erlen, Kim 과 Sok (2006), Uzun과 Tan (2004)의 연구결과와 일치한다고 할 수 있다. 제1유형은 ‘실용적 확신형’으로 보완대체요법의 효과를 단순히 인정하기보다는 실용성에 초점을 맞춘 유형이다. 보완대체요법의 문제점으로 많이 지적되는 것 중의 하나가 사람마다 효과가 다르기 때문에 일률적으로 적용하기 어렵다는 것인데, 제1유형의 대상자들은 이를 오히려 실용적인 측면으로 인식하여, 보완대체요법의 효과는 사람마다 결과가 다르게 나타날 수 있기 때문에 어떤 치료법을 일률적으로 적용하기보다는 자신한테 맞는 보완대체요법을 찾아야 한다고 인식하는 것이다. 또한 제1유형의 대상자들은 보완대체요법에 대해 효과가 없거나 의미 없는 행위이며 의학적 치료를 방해하거나 효과를 믿을 수 없다는 데는 강하게 반대를 했다. 간호학생의 보완요법에 대한 태도를 조사한 Kim (2004)의 연구에서도 보완대체요법이 엉터리 치료법이라는 데에 대해 가장 부정적인 태도를 보임으로써 본 연구결과와 일치한다. 간호학생의 주관성을 조사한 Hwang (2004)의 연구에서는 간호학생의 인식이 세 가지로 유형화되었는데 ‘긍정적 인정형’으로 명명된 사람들은 보완대체요법이 건강의 유지와 증진에 도움이 되며, 면역력을 향상시키고 심리적 지지를 제공하고 몸을 보호하며 안위를 증진시키는 것으로 인식하고, 엉터리 치료법이고 환자의 치유에 방해가 되므로 사용을 피해야 하고 과학적인 근거를 설명할 수 없으므로 신뢰할 수 없다는 데대해서는 강한 반대의 의사를 표함으로써 본 연구에서 ‘실용적 확신형’으로 명명된 대상자들과 유사한 인식양상을 보였다. 본 연구에서의 ‘실용적 확신형’의 사람은 보완대체요법에 대해 쉽게 접근할 수 있고 여러 가지 효과를 한꺼번에 기대할 수 있다는 점에서 좀 더실용적인 면을 강조한 점이 차이라고 할 수 있다. 제2유형은 ‘견제형’으로 보완대체의학의 부작용에 대한 염려와 효과에 대한 정확한 작용기전의 뒷받침을 요구하는 유형으로, Hwang (2004)의 연구에서 보완대체요법은 체계적인 검증 후에 정통적인 치료와 병행해서 사용해야 효과가 있다고 하여 ‘객관적 수용형’으로 명명한 것과 매우 유사하다. 또한 간호사를 대상으로 한Son (2002)의 연구에서 보완대체요법을 현대의학을 보완해주는 치료법으로 고려하면서 과학적인 근거를 확립하는 일이 필요하다고 제시한 것과 일치한다. Ernst (2000)도 보완대체요법을 이용하는 대상자들은 보완대체요법의 안전성과 효율성에 대해서 알고자 하며, 보완대체요법에 대해 건강관리자와 개방적으로 의사소통할 때 안정성이 확립된다고 하여 본 연구의 ‘견제형’ 유형과 유사한 것을 볼 수 있다. ‘견제형’의 사람들은 보완대체요법에 대한 효과가 사람마다 다르게 나타나므로 보완대체요법을 무조건적으로 받아들이기 이전에 임상적인 효율성에 대한 정확한 근거와 과학적인 검증에 관한 많은 연구들이 이루어져야 할 것을 강조한 유형이다. 이러한 견해는 최근 의학이나 간호학 교육에서 근거중심의 행위를 강조하고 있는 것을 반영하는 것이라 할 수 있다. 제3유형은 ‘가치 인정형’으로 보완대체의학에 대해 과학적 신뢰를 갖고 있지는 않지만 보완대체요법의 건강증진에 대한 가치를 인정하는 유형이다. 의사를 대상으로 보완대체요법의 치료 효과에 대한 태도를 분석한 Jang 과 Park (2003)의 연구에서 62.2%는 ‘설명하기는 어렵지만 보완대체요법은 효과가 있다’고 하여 작용기전에 대한 이론적 근거는 부족하지만 치료효과에 대해서는 비교적 긍정적으로 인식하고 있는 것으로 나타나 본 연구 대상자의 ‘가치 인정형’과유사한 태도를 보였다. 또한 초등학교 보건교사를 대상으로 보완대체요법의 문제점에 대한 인식을 조사한 Kim, Kim과 Cho (2007)의 연구에서 40.5%가 ‘과학적인 검증의 부족으로 치료효과가 의심된다’고 지적하였지만 학교보건실무에서 보완대체요법의 적용가능성에 대한 질문에는 72.1%가 ‘가능하다’고 하였으며, 78%가 보완대체요법의 적용이유로 ‘증상완화, 치료보조의 효과’ 때문이라고 답하여 본 연구결과와 유사한 인식을 보였다. 또한 보완대체요법 교과목을 수강한 간호학생들에게 보완대체요법의 치료적 효과에 대해조사한 Kim (2005)의 연구에서도 ‘건강유지증진을 위해 일반 대중들도 보완대체요법을 많이 적용하고 있다’에 대해 5점 만점에 3.7점으로 응답하여 비교적 긍정적 태도를 보였다. 위의 결과들을 종합해 볼 때 보완대체요법이 체계적인 지식체로 인정하기엔 과학적 근거가 부족하지만 신체의 자연 치유력과 면역력을 증가시켜 건강증진에 영향을 미친다는 본 연구의 ‘가치 인정형’과 유사하다고 할 수있다. 제4유형은 ‘제한적 수용형’으로 보완대체의학이 건강증진에 도움이 되고 심리적 안정감을 주는 여러 가지 효과가 있는 반면 부작용이 있을 수 있고 사람마다 효과가 다르게 나타날 수 있으므로 작용기전에 대한 연구도 더 필요하다고 생각하는 유형으로 무조건적으로 수용하기보다는 제한적으로 수용하는 유형이다. 대학생을 대상으로 보완대체요법의 문제점에 대한 인식을 조사한 Gwon 등(2008)의 연구에서 ‘부작용을 예측할 수 없다’가 37.7%로 가장 높았고, 23.2%가 ‘비과학적이다’라고 응답함으로써 자신에게 맞는 보완대체요법을 찾아 효과를 볼 수는 있지만 부작용에 대한 우려, 효과에 대한 객관성 부족 및 작용기전에 대한 체계적 검증의 필요성을 언급한 본 연구에서의 ‘제한적 수용형’ 대상자와 유사한 인식을 보였다. Purpose: The purpose of this study was to grasp the subjectivity of the nursing students toward CAM and put the outcomes into use as basic facts and figures in developing and applying a curriculum associated with CAM. Methods: Q methodology was employed to explore the nursing students` subjectivity from their rank-order statements. For the Q population, individual in-depth interviews and literature research were conducted. Finally, 30 participants completed 40 Q statements.

The purpose of this study was to evaluate electroless plating as a method to increase diameter of an orthodontic wire through comparison with eletroplating. After pretreatment for plating to the stainless steel orthodontic wire of 0.016 inch. the electoless plating was done under the condition of 90'c until the diameter of the wire was increased to 0.018 inch using Hessonic-Gr® which was sold by Shin-Pung metal. On the process of electroless plating the diameter of wire was measured every 5 minute to examine the increasing ratio of the wire's diameter per time unit. And to examine the uniformity, the diameter of each 3 points of the electroless-plated orthodontic wire was measured. An X-ray diffraction test was performed to analyze the nature of the plated metal and physical property test was made. Through the comparison with electroplating, following results were obtained. 1. In stiffness. yield strength, and ultimate strength of electroless plating wire group showed higher tendency than those of electroplated wire group, and in stiffness and ultimate strength there was statistically significant difference between two groups. 2. In the electroless plating wire group. the increasing ratio of the diameter was 0.O0461±0.00003 mm/5min (0.O0092 mm/min). In the electroplated wire group, that was 0.O0821±0.O0015 mm/min. 3. The results of uniformity test to measure the diameter of each 3 points showed a tendency of uniformity in all the two plating method. The results of this study suggest that the electroless plating wire is more close to the ready-made wire than electroplating wire in terams of the physical property. On the other hand. the length of plating time should be solved for the clinical application of electroless plating.

리더쉽開發의 위한 訓練프로그램에 관한 硏究

金南炫 啓明大學校 産業經營硏究所 1980 經營經濟 Vol.13 No.1

It is obvious after a review of the literature that there are almost as many definitions of management as there are writers in the field. But the common thread that appears in these definitions is the process working with and through individuals and groups in order to accomplish organizational goals. This definition makes no mention of business or industrial organizations. Management applies to all kinds of organzations. To be successful, organizations require their management personal to have interpersonal skills. Leadership is influencial process that one attempts to impact the behavior of an individual or group. Therefore, the achievement of organizational objectives through leadship is management. The quality of leadership, more than any other single factor, determines management. The quality of leadership, more than any other single factor , determines the succes or failure of an organization, and leadership is extremely complex interpersonal relationship, for which the training an deveiopment of leadership is needed. On the basis of the premise that leadership training, under certain conditions, systemetically improves the performance of the leader, this studt has the following purposes and procedures 1) To let the leader measure the leader's leadership style(personality), because the effectiveness of a group depends on the interaction between the leader's personality and the situation. 2) To let the leader know and measure the situational favorableness, the degree to which the leader has control and influence over the situation. 3) To let the leader understand how to match his leadership style (personality) with the situational favorableness. 4) To let the leader recognize the particular leadership situations in which he is most likely to succeed, and be aware of the ways of dealing with situations in which he is apt to be ineffective, 5) To let the leader know how to avoid situations in which he is likely to fail. 6) To let the above informations be used for placing right manager into the proper situations. This training program is based on a theory of leadership called the "Contingency Model," which has been developed by Fred E. Fiedler over the past 25 years. This theory holds that the effectiveness of a group or an organization depends on two interacting or contingent factors. the first is the personality of the leader which determine their leadership style. The second factor is the amount of control and influence which the situation provides leader over their group behavior, the task, and the outcomes. This factor is called "situational control or situational favorableness" This training program is designed as a practical guide to better leadership and divided into four major chapters. Chapter Ⅰ covers the basic principles of the contingency theory of leadership. Chapter Ⅱ is concerned with identifying his leadership style though measuring LPC(Least Preferred Co-Worker). Chapter Ⅲ provides the leader with the tool for accurately diagnossing and classifying leadership situations and this chapter shows shows how to measure and assess the leadership situations. Chapter Ⅳ discusses how to match the leadership style with the situational favorableness on the basis of principles of the contingency model: 1) Task-oriented leaders tend to perform best in group situations that are either very favorable or very unfavorable to the leader. 2) Relationship-oriented leaders tend to perform best in situations that are intermediate in favorableness. When this training program is applied to the training and development of managers' lesdership skill, the question of the transfer of learning will be researched through the writer's further study.

We analysed 404 patients with primary lung carcinoma who were treated at Soonchunhyang University Hospital from July, 1985 to september, 1993 in order to investigate the survival rate and epidemiolgical properties of primary lung cancer. They were 330 males and 74 females. The most prevalent decade was seventh. In terms of cell type, the squamous cell was 225 patients (55%), and adenocarcinoma, small cell, mixed type was 21%, 19%, 4%, respectively. Among non-small cell lung carcinoma, stage Ⅲa was the most prevalent one(92%). In case of small cell carcinoma, the limited stage was 64%. The 12-, 24-, 36- month survival rate of total patients was 57%, 31%, 22%, respectivley and median sruvival time was 15 months. The 36-month survival rate tended to be longer in non-small cell lung carcinoma than that of small cell lung cancer, but there was no difference between two groups, statistically. In non-small cell carcinoma, The 36-month survival rate and meidan survival time were longer in the stage Ⅰ and Ⅱ than those of Ⅲa, Ⅲb, Ⅳ (80% versus 38%, 22%, 0%, p<0.05). According to involvement of lymph node, the 36-month survival rate was longer in NO and N1 than those of N2, N3 (61.9%, 48.7% versus 17.7%, 17.3%, p<0.05). In small cell carcinoma, The 36-month survival rate and median survival rate were higher and longer in limited stage than those of extensive stage(16.1% and 13 month vs 10% and 8 month, p<0.05). In conclusion, we report here the incidence of primary lung carcinoma and the survival rate of paients with primary lung carcinoma who were treated in Soonchunhyang University Hospital.

As the current stage of the fashion begins to follow the styles of the past, the study on the past costume is getting more important, and as the methodology of the study accurately approached study through the rehabilitation of the past costume is more needed than the simple rearrangement of the historical documents. By this methodology, this study can be positioned as a recreation activity. The results of the study are as follows. 1) Style : The general silhouetts is the late crinoline style which is the period from 1860s to just before bustle. The dress is one-piece composed of fitted bodice, and skirt which the front is flat, side and back is triangular shape to the skirts. 2) Color and Material : the main color is pale stone and the sub-color is ivory and blue. The dress is made of a silk surface and cotton back and partly satin and velvet. 3) Pattern and sewing : the dress is together sewing comnined with lining and fabric. The skirt is gored skirt, the number of patterns is plenty because of the plenty of width of skirt. The double piping has various effect not only to decorate but also to conceal the seam, support the silhouette. 4) Detail : The general detail is double piping which are repeatedly used to decorate stand collar, bands of sleeve, froint bodice and gored panel seam of skirt. And the fringe and velvet ribbon are used to decorate the dress. 5) Structural characteristics : The double piping, velvet ribbon and twilled cotton are used to emphasize structural characteristics of crinoline style. And the waistband which is backed with a webbing band to reinforce it is also the structural characteristics. Synthetically, the 1886~7 day dress has the characteristics of transitional stage in which the chararcteristics of the costume of 1860s and the remnants of the characteristics of the previous costume style, and shows the characteristics of day dress well in terms of the style, color and fabrics, pattern and sewing, detail, and structural characteristics.

組織管理의 시스템에 관한 硏究 : -韓國에 進出한 多國籍企業과 同種産業의 韓國企業과의 比較硏究- A Comparative Study on the Management Systems of the Multinational Company Operating in Korea and the National Company in Korea

金南炫 啓明大學校 産業經營硏究所 1980 經營經濟 Vol.12 No.1

This study is basesd on the basic premise that the main objectives of any organization, the efficiency and the effectiveness, are largely influenced by its management systems. The purpose of this study is twofold: First, to find the comparative difference between the management systems of the two companies. Second, to contribute to establishing the framework for further study on comparative management systems and to make possible use of this study in order to diagnose the nature of the management systems employed by a particular organization. The approach adopted is an experimental study in terms of questionaires. The instrument used was largely taken from the work of Likert. The questionnaires cover all the characteristics of management systems; character of motivational forces, communication process, interaction-influence process, decision-making process, leadership process, goal-setting and contol system, and training and development system. The data analyzed in this paper were originally collected from the two kinds of companies, the one is a multinational pharmaceutical company operating in Korea (A company), and the other is a Korean company of the some industry (B company). The worker sample for this study was randomly collected in terms of the stratified sampling. A total of 265 usable questionnaires were collected(157 for A company, 108 for B company). The details of the data are on the following table: The research finding are as follows: Job Category Office Work Sales Engineer Assembly work Total Job Rank Management 15(11) 15(7) 13(6) 43(24) level Nonmanagement 20(20) 22(20) 20(6) Male 26(19) 62(46) level Assembly Female26(19) 52(38) worker Total 35(31) 37(27) 33(12) 52(38) 157(108) (parenthesis for A company 1) In terms of job catagory, as shown on the tables in the appendix, the average score for the company A and B ranged almost from 6 to 9. This result would indicate that the companies operate with a Syatem 3 mothod of management. Generally, it means that substantial confidence is shown in subordinates, communication is good, teamwork exist's in moderate amounts, and lower levels of the organization perceive some participation in goal setting. However, it is found that there is a slight difference, the company A is nearer to the System 4 than the company B in terms of job category. The above findings can be shown more in detail as follows: Company A: Engineers>Salesmen>Office Workers. Company B: Office Workers>Salesmen>Engineers. 2) In terms of job rank, the management systems of company A and B are about the same on the System 3. Expressing more in detail, the management level is nearer to the System 4 than the level of nonmanagers and assembly workers, and the nonmanagers are nearer to System 4 than assembly workers. 3) In terms of the organization as a whole, the management systems of two companies are about the same on the System 3, consultative management style. One of the causes of this result may be attributed to the convergence of the two companies through operating for twenty years in Korea, which urges the researcher undertake further studies.

교정용 선재의 직경 증가를 위한 전기도금법과 무전해도금법의 비교연구

김재남,조진형,성영은,이기헌,황현식 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.2

본 연구는 교정용 선재의 직경을 증가시키기 위한 방법으로 무전해도금법의 이용 가능성 여부를 전기도금법과의 비교를 통해 알아보고자 시행되었다. 0.016 인치 스테인레스 스틸 교정용 선재에 도금을 위한 전처리를 시행한 후, 시중에 판매되는 무전해니켈도금액(Hessonic-Gr, 신풍금속, 한국)을 사용하여 90℃ 온도에서 0.018 인치 직경이 될 때까지 도금을 시행하였다. 무전해도금 과정 중 시간에 따른 직경증가율을 구하는 한편, 도금 후 세 지점의 직경을 계측하여 균일성을 평가하였다. 도금 금속의 정성분석을 위하여 X-선 회절분석을 시행하는 한편, 물성검사를 시행한 후 전기도금한 경우와 각각 비교 분석하였다. 연구결과 무전해도금한 군이 전기도금을 시행한 군보다 강성, 항복강도, 극한강도 모두 높은 경향을 보였으며 강성과 극한강도에서 통계적으로 유의한 차이를 나타내었다 (p < 0.05). 또한 무전해도금한 군의 직경증가율은 0.00461 ± 0.00003mm/5min (0.00092mm/min)로, 전기도금한 군의 직경증가율 0.00821 ± 0.00015mm/min와 차이를 보였다. 도금 후 세 지점의 직경을 계측하여 균일성을 평가한 결과, 두가지 도금법 모두에서 균일한 양상을 보였다. 이상의 결과로 무전해도금법을 통해 직경이 증가된 선재가 전기도금법에 의해 직경이 증가된 선재보다 기존의 선재와 가까운 물성을 보임을 알 수 있었으며, 이의 임상적 적용을 위해서는 도금시간의 감소가 필요함을 알 수 있었다. The purpose of this study was to evaluate electroless plating as a method of increasing the diameter of an orthodontic wire in comparison with eletroplating. After pretreatment plating of the 0.016 inch stainless steel orthodontic wire, electroless plating was performed at 90℃ until the diameter of the wire was increased to 0.018 inch. During the process of electroless plating, the diameter of the wire was measured every 5 minutes to examine the increasing ratio of the wire's diameter per time unit. And to examine the uniformity, the diameter at 3 points on the electroless-plated orthodontic wire was measured. An X-ray diffraction test for analyzing the nature of the plated metal and a 3-point bending test for analyzing the physical property were performed. The electroless-plated wire group showed a increased tendency for stiffness, yield strength, and ultimate strength than the electroplated wire group. And there was a statistically significant difference between the two groups for stiffness and ultimate strength. In the electroless-plated wire group, the increasing ratio of the diameter was 0.00461 ± 0.00003 mm/5 min (0.00092 mm/min). In the electroplated wire group, ti was 0.00821 ± 0.00015 mm/min. The results of the uniformity test showed a tendency for uniformity in both the plating methods. The results of this study suggest that electroless plating of the wire is closer to the ready-made wire than electroplating wire in terms of the physical property. However, the length of plating time needs further consideration for the clinical application of electroless plating.
