During recent decades, the three-dimensional (3D) approach in orthognathic surgery were introduced and adopted in clinical practice, providing practical advantages to orthognathic surgeons. Even when the 3D approach is assessed based on the current state of technological development, it has advantages in orthognathic surgery and has become an essential method. It is not sure what to come next in the development of the 3D approaches, It is clear that the 3D approach represents a milestone in the development of orthognathic surgery.

According to the Korea Augmentation Satellite System (KASS) system milestone, Site Acceptance Test (SAT) has three steps test until the end of the project. SAT#1 is the first time of SAT steps and verify the KASS Reference Station (KRS) and Sub System (S/S) for the monitoring and controllable. After the equipment and software were installed at the Mission Control Center (MCC) with Central Monitoring and Control Simulator (CMS) for the SAT#1, the 1:1 test was progressed when the KRS and S/S are ready to test. SAT#1 has a 10 steps test case and it was progressed each KRS sites. The test was finished throughout the real-time monitoring and the data collection including the data analysis all of the 7 KRS sites. Finally SAT#1 was completed on December 2020 with successfully.

October 2022 marks the 50th anniversary of the founding of Journal of Korean Neurosurgical Society (JKNS). Staring as official journal of Korean Neurosurgical Society (KNS) in 1972, JKNS is a journal that is listed in the science citation index (SCI) and its impact factor has been steadily rising in recent years. The past history of JKNS was reviewed with a focus on important milestone, and the direction of future development is suggested.

A detailed survey, applications and challenges of video encoding-decoding systems is discussed in this paper. A novel architecture has also been set aside for future work in the same direction. The literature reviews span the years 1960 to the present, highlighting the benchmark methods proposed by notable academics in the field of video compression. The timeline used to illustrate the review is divided into three sections. Classical methods, conventional heuristic methods, and current deep learning algorithms are all used for video compression in these categories. The milestone contributions are discussed for each category. The methods are summarized in various tables, along with their benefits and drawbacks. The summary also includes some comments regarding specific approaches. Existing studies' shortcomings are thoroughly described, allowing potential researchers to plot a course for future research. Finally, a closing note is made, as well as future work in the same direction.

The schedule hierarchy in construction project is generally composed of three levels. The highest level is a milestone schedule and represented by Bar Chart format. The middle level is an integrated project schedule (IPS) and represented by CPM (Critical Path Method) format. The lowest level is a detail working schedule and usually represented by Bar Chart. The traditional scheduling techniques such as ADM (Arrow Diagramming Method) or PDM (Precedence Diagramming Method) cannot represent all kinds of schedule within schedule hierarchy as identical schedule format. However, the BDM (Beeline Diagramming Method) technique can represent all kinds of schedule within schedule hierarchy as identical CPM format. This paper describes the basic concept, principle, interpretation methods, and schedule computation methods of the BDM as a new networking technique that can represent all kinds of overlapping relationships between activities, and then presents an example of representing three level's schedules within schedule hierarchy by the BDM technique.

This article provides an overview of the state of attorney-client related privilege and confidentiality in Korea. It reviews the statutory framework, and how Korean courts have analyzed the privilege and confidentiality related to attorneys and their clients. It then examines the legislative initiatives Korea is currently debating with regard to adopting a more common law-style attorney-client privilege (ACP). If adopted, the new legislation will mark a significant milestone in providing guidance on how communications between attorney and client will be treated. Its impact in the context of international arbitration practice and law related to Korea is explored.

Lymphatic disorders encompass a broad spectrum of diseases involving the lymphatic system, ranging from traumatic lymphatic leaks to lymphatic malformations. Lymphatic disorders can be categorized into traumatic and non-traumatic disorders according to their etiology. These two categories may be further divided into subgroups depending on the anatomical location of the lymphatic pathology and their association with clinical syndromes. Thoracic duct embolization was a milestone in the field of lymphatic intervention that encouraged the application of percutaneous embolization techniques to treat leaks and reflux disorders in the lymphatic system. Additional access routes for embolization, including retrograde thoracic duct and transhepatic lymphatic access, have also been developed. This article comprehensively reviews a variety of options for the treatment of lymphatic disorders, from conservative management to the most recent embolization techniques.

Gd박막의 강자성-상자성 상전이 온도(Tc)이동을 조사했다. 강자성-상자성 상전이 온도에서 전기저항이 변화되는 변곡점을 관측하여 Tc를 결졍하였는데, 두께가 6600$\AA$인 Gd박막의 상전이 온도는 bulk상태의 Gd의 전이온도보다 4$\pm$0.$3^{\circ}C$정도 아래로 이동됨을 알았다. 이것은 강자성 Gd박막의 Tc이동에 대한 최초의 측정이며, 실험과 finite-sime scaling이론을 비교 분석했다.

본 논문의 목적은 항만해상풍력단지 건설을 위한 기술개발 로드 맵을 제시하는 것이다. FGI(Focus Group Interview)와 설문지를 이용한 AHP(Analytical Hierarchy Process) 방법을 적용해서 대/중/소 분류된 건설기술의 가중치를 도출했고, 분류된 건설기술에 대한 우선순위를 근거로 항만해상풍력단지 건설기술 로드 맵이 수립되었다. 기술 로드 맵은 항만해상풍력단지의 분류된 건설기술에 대한 R&D 사업을 달성하기 위한 20년간(2016년부터 2036년 까지)의 일정을 제시하고 있다. 이러한 건설기술 로드 맵은 녹색항만건설산업의 R&D 전략을 수립하기 위한 이정표로 활용될 수 있다.
