Interactive Fuzzy Physical Programming (IFPP) developed in this paper is a new efficient multi-objective optimization method, which retains the advantages of physical programming while considering the fuzziness of the designer's preferences. The fuzzy preference function is introduced based on the model of linear physical programming, which is used to guide the search for improved solutions by interactive decision analysis. The example of multi-objective optimization design of the spindle of internal grinder demonstrates that the improved preference conforms to the subjective desires of the designer.

The aim of EIT (electrical impedance tomography) system is to image cross-section conductivity distribution of a human body by means of both generating and sensing electrodes attached on to the surface of the body, where currents are injected and voltages are measured. EIT has been suffered from the severe ill-posedness which is caused by the inherent low sensitivity of boundary measurements to any changes of internal tissue conductivity values. With a limited set of current-to-voltage data, figuring out full structure of the conductivity distribution could be extremely difficult at present time, so it could be worthwhile to extract some necessary partial information of the internal conductivity. We try to extract some key patterns of current-to-voltage data that furnish some core information on the conductivity distribution such s location and size. This overview provides our recent observation on the location search and the size estimation.

Objectives: To examine the fundamental characteristics of interventional clinical trials registered in the CRIS (Clinical Research Information Service) database. Methods: We systematically analyzed the status of Korean medical interventions using the search function of the CRIS database. Results: From 2010 to January 2020, 267 Korean medicine-related clinical trials were registered with CRIS. The studies, which included many randomized trials (80.14%), focused primarily on demonstrating the effectiveness and safety of acupuncture and Korean herbal remedies. Most of these studies were government-sponsored and researcher-led clinical trials, but a few were company-sponsored trials. All trials were small and need improvement. Conclusion: This study reviews the current status of clinical trials in the field of Korean medicine and the basic data that can be used to create evidence-based Korean medicine.

This paper aims to study on bibliographic reference forms, especially focused on the forms of korean sources. Although bibliographic reference is one of the critical elements in academic works, it seems every work has it's own forms in Korea. The fact that the bibliographic reference forms in korean works are made up by option causes the present state of diversity which makes difficulty in bibliographic control. The results of this search into internal academic journals show the diversity in the entry of title and significant gap of bibliographic reference forms among disciplines.

In order to provide value-added services, next generation routers should perform packet classification for each incoming packet at wire-speed. In this paper, we proposed hierarchical priority trio (Hptrie) for packet classification. The proposed scheme improves the search performance and the memory requirement by replacing empty internal nodes in ordinary hierarchical trio with priority nodes which are the nodes including the highest priority rule among sub-trie nodes.

인터넷은 그 급속한 성장과 더불어 점차 더 나은 서비스를 제공할 것을 요구받게 되었다. 이에 따라 차세대 인터넷 라우터들에서의 지능적인 패킷 분류 기능은 필수 불가결한 것으로 여겨지고 있다. 패킷 분류란 미리 정의된 classifier에 의거하여 입력된 패킷에 매치하는 가장 순위가 높은 룰을 찾는 과정이다. 기존에 나와있는 많은 패킷 분류 검색 구조들이 출발지, 목적지 프리픽스 필드에 기반하여 룰을 추려내는 접근 방법을 사용하고 있다. 그러나 대부분의 검색 구조들은 출발지, 목적지 프리픽스 검색을 위하여 트라이 구조에 바탕을 둔 순차적인 일차원 검색을 따르고 있으며, 매우 큰 메모리를 요구한다는 단점을 가지고 있다. 본 논문에서는 메모리를 매우 효율적으로 사용하면서도 출발지-목적지 프리픽스 쌍에 기반한 이차원 패킷 분류 구조를 제안하고자 한다. 코드워드로 구성된 이진 프리픽스 트리를 구성함으로써, 출발지 프리픽스 검색과 목적지 프리픽스 검색이 하나의 이진 트리를 통해 동시에 가능하도록 하였다. 또한 본 논문에서 제안하는 구조인 이차원 이진 프리픽스 트리는 트리 구조 내부에 비어있는 노드를 포함하고 있지 않으므로 트라이 구조가 가지고 있는 메모리의 비효율성 문제를 완전히 제거하였다.

Objectives This study was aimed to propose the guideline of the diarrhea in Sasang Constitutional Medicine. Methods 1) Literature search It was investigated that the prescriptions stated the diarrhea as a main and accessory symptoms to be treated in "Donguisasangshinpyun", "Donguisusebowon Sasang Chobongwon", "Donguisusebowon Gabobon", "Donguisusebowon Sinchukbon", "Dongmuyugo" 2) Clinial paper search (1) The foreign papers were searched by using the search word with 'Sasang AND Diarrhea' in pubmed (http://www.ncbi.nlm.nih.gov/pubmed/) and The Cochrane Library(http://www.thecochranelibrary.com) (2) The domestic papers were searched by using the search word with 'Soeumin AND Diarrhea', 'Soyangin AND Diarrhea', 'Taeeumin AND Diarrhea', 'Taeyangin AND Diarrhea', 'Sasang AND Diarrhea' in NDSL (http://www.ndsl.kr), KISS(http://kiss.kstudy.com), Oasis(http://oasis.kiom.re.kr), RISS(http://www.riss.kr) (3) The extracted factors were the evaluations on the mainly complained symptom, adopted four constitutional therapy and efficacy. Results & Conclusions The guidelines for treating the diarrhea in the Four Constitutional Medicine are as follows. 1) It is to categorize the constitution. 2) The diarrhea of taeeumin is prescribed with 'A Series of Taeeumjowi-tang, Galgeunhaegi-tang, Cheongsimyeonja-tang, Sahyang-san, etc'. by classifying into cold, fever, consumption and addiction. 3) The diarrhea of soyangin is regarded as an internal disease and it is prescribed with 'Baekhaobuja-tang, Baekhaobujaijung-tang, etc'. by classifying taeeum symptom and so-yin symptom. 4) The diarrhea of soeumin is Mangeum-disease and 'Jeoryeongchajeonja-tang, Hyeongbangsabaek-san, Hwalseokgosam-tang, Hyeongbanggihwang-tang, etc'. is prescribed depending on the complication.

대부분의 기존 데이터베이스들은 빠른 저장 성능을 얻기 위하여 한 레코드의 속성들을 하드 디스크에 연속적으로 배치하는 레코드-지향 저장 모델을 사용하였다. 하지만 검색이 대부분인 데이터웨어하우스 시스템에는 월등한 읽기 성능 때문에 컬럼-지향 저장 방식이 적합한 모델이 되고 있다. 또한, 현재 플래시 메모리가 고속 데이터베이스 시스템을 위한 선호 저장 매체로 인정되고 있다. 본 논문에서는 고속 컬럼-지향 데이터베이스 모델을 도입하고, 고속 컬럼-지향 데이터웨어하우스 시스템을 위한 컬럼-인지 인덱스 관리 기법을 제안한다. 본 인덱스 관리 기법은 개선된 B트리에 기반하며, 중간 노드와 리프노드에서 내장 플래시 인덱스와 빈공간 압축을 통하여 높은 검색 성능을 얻는다. 성능 평가 결과를 기반으로 본 인덱스 관리 기법이 기존 기법보다 검색 처리 및 응답 시간 측면에서 더 우수함을 확인하였다.

The objective of this Paper was to identify the internal and external symbols of Punks, and to assess the significance of punk style giving an inspiration to many high fashion designers. For this objective. comprehension on widely discussed idea of punk, furthermore grasping the internal and external form by inquiring historically punk look, and importantly looking into new ideas pursued by punk fashion by studying traits of punk image in 1980's and after are done. Punk in the latter half of the 70's was anti-fashion expressed for the young of working class to rebel against the established generation. At first some of the fashion was popularized by the young who imitated pop stars under the specific economy of Britain, and others with movement of hippie Punk is aesthetics extremism which neglects traditionalism in the past but pursues newness. It denied traditional way of expression and principles of aesthetics but created newness. Punk look was symbolized as poor look. grotesque, androgynous, black, graffiti, and bricolage. And the internal meanings of these symbols are ego-screaming, expression of nihilism, resistance, irony and ridicule, search for hedonism. The punk phenomenon continues today. Some teens still cling to the complete look. whether they have punks' idea and value or not. Diverse elements of punk style play a major role in the current trend of fashion and a source of the fresh inspiration for the high fashion designers. Punk style is truly the story of a fad that turned to fashion.
