Minutes of the state council are the highest level records which can show the overall decision making process at the state level. The purpose of this study is to suggest the methodology for designing historical contents based on relational structure of minutes of state council and records of ministries in the period of Rhee Regime. The methodology has three steps; first, it suggests directions of DB design that represent the basic information and agenda of the state councils through the period of Rhee Regime. Second, it proposes subject classification scheme for major policy matters in the period. to which each agenda will be assigned and related ministries' records will be linked. Third, it suggests the basic structure and procedures to develop the historical contents on each subject matter based on the minutes and relational records of ministries.

Peri-implant disease is a serious problem that plagues today's dentistry, both in terms of therapy and epidemiology. With the expansion of the practice of implantology and an increasing number of implants placed annually, the frequency of peri-implant disease has greatly expanded. Its clinical manifestations, in the absence of a globally established classification, are peri-implant mucositis and peri-implantitis, the counterparts of gingivitis and periodontitis, respectively. However, many doubts remain about its features. Official diagnostic criteria, globally recognized by the dental community, have not yet been introduced. The latest studies using metagenomic methods are casting doubt on the assumption of microbial equivalence between periodontal and peri-implant crevices. Research on most of the features of peri-implant disease remains at an early stage; moreover, there is not a commonly accepted treatment for it. In any case, although the evidence so far collected is limited, we need to be aware of the current state of the science regarding this topic to better understand and ultimately prevent this disease.

Purpose: The purpose of this study was to examine the degree of self-care, symptom experience and disease state among the patients with liver cirrhosis and to identify its correlation. Methods: The subjects were 220 patients with liver cirrhosis who were treated in D-university hospital in Busan. The instruments used for study were the self-care inventory, the symptom experience inventory and modified childpugh classification scale. Results: The average points of the patient's self-care performance, symptom experience, and disease status were 3.67, 29.10 and 6.12 respectively. Their self care was negatively correlated to symptom experience, and symptom experience was positively correlated to disease state. Conclusion: This research findings suggested that active self-care by patients with liver cirrhosis might contribute to reduce various symptoms they can undergo and to prevent aggravation of disease state. Therefore, patients with liver cirrhosis have to carry out self care actively in daily life and discreet nursing intervention should be offered to facilitate their self-care.

Simplified techniques based on in situ testing methods are commonly used to assess seismic liquefaction potential. Many of these simplified methods were developed by analyzing liquefaction case histories from which the liquefaction boundary (limit state) separating two categories (the occurrence or non-occurrence of liquefaction) is determined. As the liquefaction classification problem is highly nonlinear in nature, it is difficult to develop a comprehensive model using conventional modeling techniques that take into consideration all the independent variables, such as the seismic and soil properties. In this study, a modification of the Multivariate Adaptive Regression Splines (MARS) approach based on Logistic Regression (LR) LR_MARS is used to evaluate seismic liquefaction potential based on actual field records. Three different LR_MARS models were used to analyze three different field liquefaction databases and the results are compared with the neural network approaches. The developed spline functions and the limit state functions obtained reveal that the LR_MARS models can capture and describe the intrinsic, complex relationship between seismic parameters, soil parameters, and the liquefaction potential without having to make any assumptions about the underlying relationship between the various variables. Considering its computational efficiency, simplicity of interpretation, predictive accuracy, its data-driven and adaptive nature and its ability to map the interaction between variables, the use of LR_MARS model in assessing seismic liquefaction potential is promising.

In many periods of Korean history, state-sponsored medical books played a crucial role in terms of distributing medical knowledge as well as systemizing medical information. This study uses comparative analysis to examine the tables on contents of state-sponsored medical publications in Korea. These tables of contents reveal the placement and categorization of medical knowledge, which implicates the ways in which diseases were classified. Historically, Korean medicine has been influenced by Chinese medicine, and at the same time, it has made steady efforts to localize Chinese medicine. This paper argues that Korean medicine adopted the Chinese styles of categorizing medical knowledge in the middle of 15th century for the first time and shows the tendency to Koreanize medical knowledge through the early 17th century. In the 18th century the Complete Records of Medicine (醫部全錄) shows the trace of referring the style of Korean medical book, the Treasured Mirror of Eastern Medicine (東醫寶鑑) in terms of categorizing medical knowledge.

State-of-art instance segmentation networks are successful at generating 2D segmentation mask for region proposals with highest classification score, yet 3D object segmentation task is limited to geocentric embedding or detector of Sliding Shapes. To this end, we propose an amodal 3D instance segmentation network called A3IS-CNN, which extends the detector of Deep Sliding Shapes to amodal 3D instance segmentation by adding a new branch of 3D ConvNet called A3IS-branch. The A3IS-branch which takes 3D amodal ROI as input and 3D semantic instances as output is a fully convolution network(FCN) sharing convolutional layers with existing 3d RPN which takes 3D scene as input and 3D amodal proposals as output. For two branches share computation with each other, our 3D instance segmentation network adds only a small overhead of 0.25 fps to Deep Sliding Shapes, trading off accurate detection and point-to-point segmentation of instances. Experiments show that our 3D instance segmentation network achieves at least 10% to 50% improvement over the state-of-art network in running time, and outperforms the state-of-art 3D detectors by at least 16.1 AP.

In this paper, we review papers which report to the all solid-state electroactive polymer-based tunable lens. Since electroactive polymer-based tunable lenses change their focal length by responding to electric stimuli, it can be minimized the size and weight of optical modules. Thus, it has been received attention in the robot, mobile device and display industry. The all solid-state electroactive polymer-based tunable lenses can be classified into two categories depending on the classification of materials: ionic electroactive polymer-based lenses and non-ionic electroactive polymer-based lenses. Most of the ionic electroactive polymer-based tunable lenses are fabricated with ionic polymer-metal composite. So, the ionic electroactive polymer-based tunable lenses can be operated under low electric voltage. But small force, slow recovery time and environmental limitation for operation has been pointed to the disadvantage of the lenses. The non-ionic electroactive polymer-based tunable lenses are classified again into two categories: dielectric polymer-based tunable lenses and polyvinylchloride gel-based tunable lenses. The advantage of the dielectric polymer-based tunable lenses is fast response to electric stimuli. But the essential flexible electrodes degrade performance of the lens. Polyvinylchloride gel-based tunable lens has reported impressive performance without flexible electrodes.

The Purpose of this article is to identify the specific characteristics of borderline disorder in adolescence to conceptualize the borderline state as an adolescent process different from borderline personality disorder in adult, and to classify them according to it's unique clinical feature, porcess and outcome. The development of borderline disorder in adolescent, epidemiology, comorbid disorders and differential diagnosis, pre-existing sub-classification systems, and etiology in theories of psychodynamics, biological theories, experimental studies, and follow-up studies are reviewed. The authors conceptualize the adolescent borderline state include all clinical states generated by re-emergence of unresolved rapproachement conflicts in adolescent, and propose that there are four subgroups in adolescent borderline state. (1) Borderline state as an adolescent process. (2) Borderline state associated with psychotic disorders (3) Borderline state as an initial stnge of typical borderline personality disorder (4) Borderline state associated with organic problems. Conceptually, borderline state in adolescence is not a simple continuation of primary failure of separation-individuation but a struggle for mastering unresolved separation-individuation conflicts in adolesance i.e., the second separation-individuation state, and if it fails this time, the struggle might continue into adult life as borderline personality disorder.
