  • 글로벌 공급사슬 환경에서 글로벌하게 분산 조달, 생산, 유통하게 됨에 따라 전체 공급사슬의 스케줄을 최적화하기 위해서 공급사슬상의 개별 기업 혹은 공장의 스케줄링 최적화뿐만 아니라 각 개별 기업 혹은 공장의 스케줄을 긴밀하게 연계하는 것이 필요하게 되었다. 이는 경쟁과 협력을 동시에 하는 개별 기업 혹은 공장을 개별 에이전트로 보고 각 에이전트간 커뮤니케이션을 통해 개별 에이전트가 관할하는 스케줄러의 스케줄을 조정함으로써 가능해진다. 하지만 전통적인 스케줄링 연구는 개별 스케줄러의 최적화에 집중되어 있고, 에이전트 연구는 스케줄링 도메인에 적용한 예가 제한적이며 이 예도 개별 스케줄러 내의 최적화에 적용하거나 실제 현장 문제가 아닌 실험실 문제 수준에 그치고 있다. 따라서 본 연구에서는 전체 글로벌 공급사슬 스케줄의 최적화를 위해 개별 기업 혹은 공장 스케줄러의 스케줄링을 연계하는 경쟁협력 스케줄링을 위한 에이전트 기반 플랫폼을 구축하였다. 글로벌 공급사슬에서 경쟁협력 스케줄링을 위한 에이전트 기반 플랫폼을 구축하기 위해 첫째, 경쟁협력 스케줄링 분류 체계를 확립하고, 둘째, 경쟁협력 스케줄링을 위한 에이전트를 설계하고, 셋째, 경쟁협력 스케줄링을 위한 지식기반 의사결정 모델을 개발한 후, 넷째 조선산업에 적용 가능한 프로토타입 시스템을 개발했다. 이를 통해 글로벌 공급사슬상의 전체 스케줄의 품질과 에이전트간 커뮤니케이션의 노력에 대한 균형점을 찾을 수 있다. 이를 통해 공급사슬내 개별 기업 혹은 공장의 부분 최적화를 극복할 수 있는 대안을 제시할 것으로 기대한다.

  • The South Korean society has experienced many changes since the sinking of ROKS Cheonan. The government reviewed its defense posture and adopted the 5·24 Measure in its relations with North Korea. As a result, the people of South Korea became more conscious of security situations on the Korean peninsula while North Korea's economy suffered badly. Meanwhile, the South Korean government has taken a flexible stance toward North Korea in terms of exchange and cooperation since September 2011. The flexible stance was to manage inter-Korea relations in a stable manner and relieve the hardships of the North Korean people while preserving the spirits and purposes of the 5·24 Measure. The UN Security Council adopted twenty-six resolutions and statements on North Korea since June 25, 1950. They include thirteen U.N. Security Council resolutions including those concerning nuclear weapons or missile programs, nine Presidential statements, and four press statements. Resolution 82, the first U.N. resolution on North Korea, came when the Korean War broke out. Resolution 825, the first one related to nuclear or missile programs, was adopted in response to North Korea's withdrawal from the NPT. Apart from these U.N. resolutions, the United States has imposed separate sanctions against North Korea. North Korea's nuclear weapons program can be considered in comparison with that of Iran in terms of the consequences they create for the regional security. The Security Council has adopted six resolutions on Iran so far. One should note that the resolutions on Iran have had much stronger sanctions compared to those imposed on North Korea. That is, while the North Korea case may be viewed as a more serious threat to international security from the perspective of nuclear weapons development or proliferation, tougher sanctions have been placed on Iran. There are two approaches that South Korea should take in addressing the related issues. First, we should aim to reduce the gap between sanctions imposed on Iran and North Korea. It is difficult to understand that a country with more serious problems is rewarded with lighter sanctions. We should take measures through the Security Council Sanctions Committee to make individuals and groups in North Korea that play a central role in developing nuclear weapons and missiles subject to additional sanctions. Second, we have to change. Other countries in the international community have become tired of North Korea's nuclear issue and now they look to South Korea for initiative. We should correctly understand this current situation and play a leading role within our capacity. Knowingly and unknowingly, the notion that the North Korean nuclear issue may be left to South Korea has been spread around the international community. Although the situation is grave, we should try to open a new horizon in ushering in the unification era by taking the initiative with confidence that there is a looming hope ahead of us. For these tasks, we should stop thinking in the old way that has been ossified for the last two decades. We should not be pushed around by neighboring great powers in dealing with North Korea related issues anymore; we should take the initiative with resolution that we will play our role at the center of four great powers and with confidence that we can do it. Based on the confidence that the Republic of Korea has become a country with enough capacity to take the initiative, we should establish a 'National Grand Strategy' representing South Korea's strategic vision that the unification is the ultimate solution to the problems related to North Korea's nuclear weapons program.

  • The health care environment becomes more competitive every day. It has fallen to nurse managers - from vice presidents of patient care to nurse managers and their assistants - to recruit and develop a workforce that successfully meets the needs of both patients and the organization. This means employees who demonstrate advanced critical thinking skills, creative problem solving, and sound decision making skills combined with clinical skills and patient advocacy. The environment which nurse managers create and the way they relate to their workforce, are pivotal to organizational viability. Especially leadership of first -line nurse managers contributes to the success of their organizations. First-line nurse managers are deserved to be one of the most administrative supervisors through the middle stratum in a hospital organization as being a manager in the field service if assessed from the overall aspects of hospital, as being an interim managers in the nursing department as well as being a supreme supervisor in a unit in terms of an organizational structure in the hospital. Similarly, as a compete leader, the first-line nurse managers have not only a professional which is qualified to perform a role of appropriate coordination with medical staff and key personnel but also hold an important key position a being responsible for performing his or her given role. The first-line nurse manager is expected to manage human and fiscal resources in ways not required before. While an identified need for well-prepared first-line nurse manager continues to plague the profession, first-line nurse managers often have difficulty providing the leadership required. The need leadership training to function effectively in their positions. But we hardly find a useful leadership training program for first-line nurse managers, therefore the purpose of this study was to developed the leadership training program for them. The steps of leadership program development were below: 1st step, 2 studies were done before develop a leadership program. One was done to ask to first-line nurse managers what they want to learn through leadership training, the other one was to ask the staff nurses what their opinions are for their first-line nurse managers leadership. 2nd step was searching other leadership programs contents. The results of this study were below: The total amount of hours is 24. Leadership training program contents are : Future of nursing profession (210min), understanding basic factor's of leadership and leadership theories(310 min), self understanding as first- line nurse managers(320 min), basic principle and practice of interpersonal relationship(210 min), assertiveness training, conflict management (180min), and group study(210min). This is challenging time to be a leader, especially in nursing. As nurse managers look toward the new millennium, it seems as through the same struggles are ahead that are behind. So nurse managers need to embrace change with a positive attitude. They need to demonstrate risk taking and support it in their staffs. All these things are possible that after they participate the leadership training program.

  • 중국 상해 양산항과 부산 신항을 SWOT분석은 물론 항만경쟁력 상의 주요 결정요인인 항만입지, 항만시설, 항만비용 및 항만 서비스 측면에서 분석하여 부산 신항의 특성을 도출하여 이에 따른 부산신항의 특화전략을 제시하였다. SWOT분석에 의하면 부산 신항은 지정학적 우위로 기간항로의 중심에 위치하고 있으며, 충분한 안벽전면 수심과 첨단의 하역장비를 구비하여 최고의 물류서비스를 제공할 수 있다는 점이다. 또한, 항만배후단지 개발을 통하여 환적 물동량은 물론 자체물동량의 성장잠재력을 확보할 수 있다. 항만경쟁력 측면에서는 신항이 항만입지의 미주항로, 항만서비스의 입항 소요시간 출항소요시간 게이트 반출입시간 정보서비스 수준 등에서만 우위를 유지할 뿐 항만입지의 중심성, 항만시설의 수심 시설규모.평균장치 일수 하역 및 이송장비, 항만비용의 시설 사용료 관련 서비스료 하역비 보관료, 그리고 항만서비스의 항만생산성 등에서 열위를 면치 못하고 있다. 이러한 두 가지 측면에서 분석한 내용을 바탕으로 신항이 동북아 중심항으로써 그 지위를 확보하기 위하여 양산항과 비교하여 부산 신항이 특화할 수 있는 중점전략으로는 유 라시아 대륙을 잇는 철도운송의 추진, 신항의 배후단지 조기개발에 의한 자체 물동량 확보, 항만서비스 수준의 획기적 향상, 항만 마케팅활동의 차별화 전략 및 항만 생산성의 제고 등을 제시할 수 있다. 물론 이들 전략 외에도 환적 네트워크의 확충, 항만 인프라의 조기 구축, 항만 생산성의 증대, 외국기업 유치를 위한 기업환경의 조성 및 신속한 의사결정 및 업무추진 등을 들 수 있다.

  • Exposure and Concealment have been continued as important way to express fashion and theme as well, especially in women fashion. Exposure can make themselves attractive, and concealment emphasizes this way of being attractive by exposure. Besides the temptable effect of exposure, the ideology which put women next men in society has made a prominence on the fact exposure is significant theme in women fashion. It means that women's image of 'Being seen as Object' (this can be explained by relation passive between active) in society has driven female emphasize in using and focusing on exposure to be attractive. Also the other important thing in women fashion has been considered is concealment. The fact that society has demand women more chaste duty in detail may have meaningful thing in the condition that instigates women take off being attractive to the subject, considering ideology, men. Therefore attractive femininity has to be suggested by virtue and temptation, it is common sense that looking just shallow or too strict are far from criteria of ideal beauty. Namely, the concept for exposure coexists with concealment not only constructively but also naturally in fashion. Technique that can be accentuate for effective exposure differently from method to show unilaterally is needed, and this technique can promote new fashion. And according to the theory of Freud, women means' Absence (lacking penis)', this female's Lack Image induces male castration complex therefore 'Fetishistic Look' which transfers something phallic into specific things or parts of body is adopted, sort of object cathexis. This is revealed as some parts of women body are diverted into object for sexual love, symbolic equivalent. For example, women's parts like legs or breast are remarked as erotogenic zone and as time goes, when no more the zone are felt sexual by exposure, other somewhere felt mysterious (felt something sexual) used to be stressed by exposing. As it were, it can be possible that exposing part on women body (sexual part) moved as time passed because of what previously stated. Especially, the concept of exposure and concealment in women fashion should explain not only from a point of view of style for the beautifulness but also from wearer's immanent intention, further more relationship with ideology. About the present situation becoming bolder in women fashion, it is said that women express confidence as the position of women is elevated higher socially, the more women get freedom. But if we consider this psychoanalysis opinion mentioned ahead, the possibility can not be excluded that the exposure can get emphasizing according as the need of feminine modesty gets decreasing from ideal femininity society, men want. This study about exposure and concealment was made progressed through the theory of Freud who originated psychoanalysis, presented many theories. But nowadays contradictions are being brought up against Freud's theory including conventional philosophy like male chauvinism and adjust studies get suggested. Hereupon, there may be limitation in making no allowance of contradiction and following his theory.

  • The Last PlannerSystem (LPS) has been implemented on construction projects to increase work flow reliability, a precondition for project performance againstproductivity and progress targets. The LPS encompasses four tiers of planning processes:master scheduling, phase scheduling, lookahead planning, and commitment / weeklywork planning. This research highlights deficiencies in the current implementation of LPS including poor lookahead planning which results in poor linkage between weeklywork plans and the master schedule. This poor linkage undetermines the ability of theweekly work planning process to select for execution tasks that are critical to projectsuccess. As a result, percent plan complete (PPC) becomes a weak indicator of project progress. The purpose of this research is to improve lookahead planning (the bridgebetween weekly work planning and master scheduling), improve PPC, and improve theselection of tasks that are critical to project success by increasing the link betweenShould, Can, Will, and Did (components of the LPS), thereby rendering PPC a betterindicator of project progress. The research employs the case study research method to describe deficiencies inthe current implementation of the LPS and suggest guidelines for a better application ofLPS in general and lookahead planning in particular. It then introduces an analyticalsimulation model to analyze the lookahead planning process. This is done by examining the impact on PPC of increasing two lookahead planning performance metrics: tasksanticipated (TA) and tasks made ready (TMR). Finally, the research investigates theimportance of the lookahead planning functions: identification and removal ofconstraints, task breakdown, and operations design.The research findings confirm the positive impact of improving lookaheadplanning (i.e., TA and TMR) on PPC. It also recognizes the need to perform lookaheadplanning differently for three types of work involving different levels of uncertainty:stable work, medium uncertainty work, and highly emergent work.The research confirms the LPS rules for practice and specifically the need to planin greater detail as time gets closer to performing the work. It highlights the role of LPSas a production system that incorporates deliberate planning (predetermined andoptimized) and situated planning (flexible and adaptive). Finally, the research presents recommendations for production planningimprovements in three areas: process related, (suggesting guidelines for practice),technical, (highlighting issues with current software programs and advocating theinclusion of collaborative planning capability), and organizational improvements(suggesting transitional steps when applying the LPS).

  • 본 논문은 가중 퍼지소속함수 기반 신경망(Neural Network with Weighted Fuzzy Membership Functions, NEWFM)을 이용하여 클래스의 분류강도를 구하고 비선형 시계열 추이선을 예측하는 방안을 제안하고 있다. NEWFM에 의하여 추출된 가중퍼지 소속함수(BSWFM)를 이용하여 입력값에 대한 분류강도를 구하게 되고, 이들에 대한 가중평균 역퍼지화를 통하여 비선형 시계열 추이선을 작성한다. 실증분석결과 NEWFM은 목표 클래스로 설정된 GDP에 대하여 92.22%의 분류성능을 보여 주었다. 따라서 동 비선형 시계열 추이선은 대표적인 경기지표인 GDP 추이에 비교적 높은 유사도를 나타내는 가운데 분석대상기간인 제5순환기-제8순환기 중 정점(peak)에서 평균 12개월, 저점(trough)에서 평균 6개월의 선행성(look-ahead)을 보여 줌으로써 경기변동에 앞서 상당기간의 시차를 둔 예측지표로서 활용가능성이 입증되었다. NEWFM은 그 특징선택(feature selection)에 의하여 선행지표 10개 중 3개의 축소를 기할 수 있게 해 줌으로써 보다 적은 수의 경제지표를 가지고도 분류성능을 90.0%에서 92.22%로 향상을 기하는 가운데 효율적인 예측기능을 수행할 수 있음이 입증되었다.

  • Going back to long chinese medical history, there were many different methods of treatment according to the origin of local chinese areas, such as Bian-Shi(?石) from east, herbal therapy from west, acupuncturing from south, moxibustion from north, and mainpulating therapy from middle china. In the midst of these therapies, acupuncture needling had developed very much both in theories, shapes, usages and also in theraputic boundray. Historical books dealing with acupuncture had introduced and used Jiu-Zhen as a tool for acupuncture needling in common. But there are some differences between each texts about in shape, use, and there are also another different point of view about the interrelationship between Bian-Shi and Ji-Zhen. So the author, in this research, tried to look for how Jiu-Zhen had took on its real kinds, adaptive usages, theraputic boundaries, many different skills of needing. By researching over ${\ulcorner}$ Ling-Shu, Jiu-Zhen(靈樞,九鍼)${\lrcorner}$, ${\ulcorner}$ Ling-Shu, Jiu-Zhen-Shi- Yi-Yuan(靈樞,九鍼十二原)${\lrcorner}$, ${\ulcorner}$ Ling-Shu, Guan-Zhen(靈樞,官鍼)${\lrcorner}$, and by compar- ing them with the contents of Jiu-Zhen in ${\ulcorner}$ Zhen-Jiu-Yi-Jing(鍼灸甲乙經)${\lrcorner}$ ${\ulcorner}$Zhen-Jiu-Da-Cheng (鍼灸大成)${\lrcorner}$, the author discovered small conclusions such as following. 1. Taking Jiu-Zhen in a narrow sense, it only repesents nine different needle used in different cases. But in large sense, this means nine different deedling methods using each different needles which is represented in the form of Wu-Ci ( 五剌 ), Shi-Yi-Ci ( 十二剌 ) in ${\ulcorner}$ Ling-Shu, Guan-Zhen ${\lrcorner}$ 2. Jin-Zhen has been first originated from stone age as a substitute for Bian-Shi and through bronze and iron age, it followed a process of it's own shape and applicating functions. As an example, the moxibustional therapies shown in ${\ulcorner}$ Zu-Bi-Shi-Yi-Mai- Jiu-Jing ( 足臂十一脈灸經 )${\lrcorner}$ ${\ulcorner}$ Yin-Yang-Shi-Yi-Mai-Jiu-Jing ( 陰陽十一脈灸經)${\lrcorner}$ in ahead of ${\ulcorner}$ Nei-Jing ( 內經 )${\lrcorner}$ era, was relationship in acupuncturing skills and shape. So Jiu-Zhen had been originated on the base of Bian-Shi in ancient times to develop into delicate shape, skill, and theraputic foundation of modern oriental medicine.

  • 코로나19 감염병 확산으로 인해 비대면진료가 일시적으로 허용되었고 지속 필요성에 대한 공감대가 커지고 있다. 그러나 현행 「의료법」은 의사와 의료인 간의 원격의료만 허용하고 있다. 비록 법률해석을 통해 의사와 환자 간의 비대면진료가 허용된다는 의견도 있지만 전체적인 법률체계를 고려할 때 허용되지 않는 것으로 보는 것이 타당하다. 그럼에도 불구하고 과학기술의 발달과 감염병 출현 시기의 단축 등을 종합적으로 고려할 때 앞으로 대면진료만을 고집하는 것은 바람직하지 않다. 따라서 안전하고 효과적인 비대면진료가 이뤄질 수 있는 방안을 고민하고 제도화하는 것이 전략적으로 필요하며, 또 중요하다. 이를 위해 앞으로 논의되어야 할 법률적 쟁점들을 미리 살펴보는 것이 이 글의 목적이다. 비대면진료를 구체적으로 규율하기 위해서는 우선 비대면진료의 범위와 대상 질환 그리고 시행 주체가 명확해야 한다. 또한 비대면진료가 시행되기 위해서는 구조적으로 시설과 장비 기준이 마련되어야 하고 기능적으로는 해당 시설과 장비를 통해 의사와 환자가 적극적으로 소통하고 정보를 실시간 교환할 수 있어야 하고 비대면진료 과정에서 발생하는 정보를 보호하기 위한 관리체계가 구체적으로 마련되어야 한다. 이처럼 비대면진료를 시행하기 위해 새롭게 정비되어야 할 내용뿐만 아니라 비대면진료를 통해 발생할 수 있는 책임의 문제와 비용의 문제도 구체적으로 정리될 필요가 있는 법적 쟁점이다.
