차량검지시스템(VDS) 메타데이터의 표준화에 관한 연구

박형기 ( Hyeong-ki Park ) 한국정보처리학회 2007 한국정보처리학회 학술대회논문집 Vol.14 No.1

본 연구에서는 차량검지시스템을 이용하여 메타데이터의 검지시스템의 하드웨어와 소프트웨어가 도로에 적합한 시스템이 되도록 실험을 통하여 이를 검증하고, 표준화를 위해 제안하였다. 첫째, 교통정보를 메타데이터하고자 할 때 그 구축범위가 너무 광범위한 점을 보완하여 시내 교통정보의 범위를 줄이고자 적용범위로 VDS(차량검지시스템 : Vehicle Detection System)의 메타데이터 구성요소에 대한 표준을 마련하였다. 둘째, 본 표준에서는 차량의 속도, 단위 시간당 차량의 통과수 및 점유시간 등을 조사할 수 있는 VDS의 메타데이터 구성요소를 추출하고 데이터 요소에 대한 정의 및 기술형식을 정의하였다. 셋째, VDS의 메타데이터 표준지정은 교통정보의 데이터 요소 및 형식을 동일하게 사용하도록 함으로써 상이한 개발업체에 의해 개발된 시스템의 교통정보를 일관성 있게 표현할 수 있다. 넷째, 본 표준은 VDS 메타데이터의 데이터 요소명을 표준화하기 위해서 Data Dictionary를 구축하여 실제 데이터 요소에서 data dictionary에서 정의된 약어들의 조합으로 표시하여 데이터 모델링시 유용하게 쓰일 수 있도록 하였다.

식육가공의 염지제에 관한 연구 : 4. Ascorbic acid 와 Tocopherol 의 첨가수준이 염지육에 미치는 효과 4. Effects of the combined levels of ascorbic acid and α - tocopherol on cured meat

박형기,오동환 한국축산학회 1984 한국축산학회지 Vol.26 No.5

A study was conducted to determine the effects on a mixture of ascorbic acid and α-tocopherol in the pH, color and residul nitrite of the cured meat. The results obtained were summarized as follows; The pH value was shown a little low trend according to the increase of ascorbic acid and α-tocopherol during the period of curing meat, but it was not to be markedly different. According to the increase of the amounts of ascorbic acid and α-tocopherol the color development of the cured meat was improved, and the residual nitrite of the cured meat was decreased. As the results obtained through this experiment the addition of ascorbic acid and α-tocopherol would be more desirble than 500ppm in each.

광 포획 향상을 위한 다중 아키텍처 식각 기술을 적용한 박막 실리콘 태양전지에 관한 연구

박형기 ( Hyeong Gi Park ),이준신 ( Junsin Yi ) 한국전기전자재료학회 2024 전기전자재료학회논문지 Vol.37 No.3

This work focuses on improving the light-harvesting efficiency of thin-film silicon solar cells through innovative multi-architecture surface modifications. To create a regular optical structure, a lithographic process was performed to form it on a glass substrate through various etching processes, from Etch-1 to Etch-3. AZO was deposited on top of the structures and re-etched to create a multi-architectural surface. These surface-modified structures improved the light absorption and overall performance of the solar cell through changes in optical and physical properties, which we will analyze. In addition, we investigated the effect of post-cleaning on the etched glass structures through EDX analysis to understand the mechanism of the etching action. The results of this study are expected to provide important guidelines for the design and fabrication of solar cells and other photovoltaic devices.

韓·英兩語의 文法的 特質의 比較를 通해서 본 英語學習上의 問題點 : 形態論을 中心으로

朴炯基 釜山敎育大學 1970 부산교육대학 논문집 Vol.6 No.1

This study aims to compare some grammatical features of Korean language with those of English language in order to find out some fundamental problems for the Koreanp people in teaching and learning of English language. Before any of the questions of how to teach a foreign language must come the much more important preliminary work of finding the special problems arising out of any effort to develop a new set of language habits against a background of different native language habits. It is the writer's firm belief that the key of the achievement and progress in mastering English language lies in a careful systematic comparison of the descriptive structural analyses of Korean and English language. The result of such comparison may surely prove of fundamental value for the preparation of more effective teaching methods, teaching materials, and English learning experiments. The aims for a systematic comparison of these two languages are as follows: (1) Significance for Teaching Methods It is generally assumed that Korean students who come in contact with English language will find some features of it quite easy and others expremely difficult. Those elements that are similar to Korean language will be, of course, simple for them, and those elements that are different will be difficult. The teacher who has been provided with the knowledge resulted by a comparison of English with Korean will be aware of what the real learning problems are and can better be equipped with effective teaching methods. (2) Significance for Teaching Materials Modern English textbooks and supplementary materials should give due emphasis to those elements or features that are difficult because they are different from those of the native language of the students. Teaching and learning materials of English language should be graded as to grammatical structure, pronunciation, vocabulary, etc., giving priority to those features that are different from Korean language. And grading can be done best after the kind of comparison the writer is presenting in this study. (3) Significance for Research of the English Language. By using the results of linguistic comparison of Korean and English, we can pin point our research problems, and individuals can carry out highly significant experiments.

效率的인 英語學習指導를 爲한 韓·英兩語의 文法的 特質의 比較硏究

朴炯基 釜山敎育大學 1974 부산교육대학 논문집 Vol.10 No.1

In teaching and learning of English language, it has been our experience that there are patterns of English language that cause much difficulty in learning, and there are those that do not cause much difficulty. And it is the writer's assumption that through the systematic comparison of Korean and English languages we can easily discover and describe the difficult patterns that the Korean students will have in learning English. This study aims to compare some grammatical features of Korean language with those of English language in order to find out some fundamental problems for the Korean People in teaching and learning of English language. Before any of the questions of how to teach a foreign language must come the much more important preliminary work of finding the special problems arising out of any effort to develop a new set of language habits against a background of different native language habits. It is the writer's firm belief that the key of the achievement and progress in mastering English language lies in a careful systematic comparison of the descriptive structural analyses of Korean and English languages. The result of such comparison may surely prove of fundamental value for the preparation of more effetive teaching methods, teaching materials, and English learning experiments. The aims for a systematic comparison of these two languages are as follows: (1) Significance for Teaching and Learning Methods. It is generally assumed that Korean students who come in contact with English language will find some features of it quite easy and others extremely difficult. Those elements that are similar to Korean language will be, of course, simple for them, and those elements that are different will be difficult. The teacher who has been provided with the knowledge resulted by a comparion of English with Korean will be aware of what the real learning problems are and can better be equipped with effective teaching methods. (2) Significance for Teaching Materials. Modern English textbooks and supplementary materials should give due emphasis to those elements or features that are difficult because they are different from those of the native language of the students. Teaching and learning materials of English language should be graded as to grammatical structure, pronunciation, vocabulary, etc., giving priority to those features that are different from Korean language. And grading can be done best after the kind of comparison the writer is presenting in this study. (3) Significance for Research of the English Language. By using the results of linguitic comparison of Korean and English, we can pin point our research problems, and individuals can carry out highly significant experiments.

원자력구조물(原子力構造物)의 지진해석(地震解析)에 사용(使用)되는 입력운동(入力運動)에 대한 고찰(考察)

박형기,유철수,Park, Hyung Ghee,Yu, Chul Soo 대한토목학회 1985 대한토목학회논문집 Vol.5 No.2

원자력(原子力) 구조물(構造物)의 내진해석(耐震解析)에 사용(使用)되어온 입력운동(入力運動)의 가속도 크기와 지속시간(持續時間)을 조사(調査)하였다. 그 중 수치화(數値化)된 자료를 얻을 수 있었던 지속시간(持續時間) 24초(秒)인 두 개의 인공가속도(人工加速度)-시간이력곡선(時間履歷曲線)에 대하여 가속도응답(加速度應答)스펙트럼과 스펙트럼강도(强度)를 계산하여 특성(特性)을 파악하고, 지속시간(持續時間) 이외의 다른 특성(特性)이 크게 다르지 않도록 가속도(加速度) 곡선(曲線) 하나를 개선(改善)시켜 지속시간 15초(秒)의 다른 인공가속도(人工加速度)-시간이력곡선(時間履歷曲線)을 만들었다. 24초(秒)의 두 곡선(曲線)과 개선(改善)시킨 곡선(曲線)을 각각 원자력(原子力) 5, 6호계(號繼) 부품냉각건물(部品冷却建物)의 모델에 입력(入力)시켜 지진해석(地震解析)을 수행(遂行)하였다. 24초(秒)의 원(原) 곡선(曲線)과 이로부터 개선(改善)시킨 곡선(曲線)을 사용(使用)한 결과(結果)는 거의 동일(同一)하였으나, 24초(秒) 두 곡선(曲線) 사용(使用)한 결과(結果)는 그 경향(傾向)은 같으나 큰 차이(差異) 보였다. 또한 본(本) 연구(硏究)에서 사용(使用)한 모델에 개선(改善)시킨 곡선(曲線)의 사용(使用)이 컴퓨터 이용시간(利用時間)을 약 절반으로 줄일 수 있음을 알았다. The acceleration levels and durations of seismic inputs for nuclear power plant design are surveyed. Among those inputs, two artificial acceleration time histories with same acceleration level and duration are selected and their characteristics are studied by calculating response spectra and spectrum intensity. The selected time histories which have the duration of 24 sec. satisfy the design response spectra of US Nuclear Regulatory Commission Regulatory Guide 1. 60. One of the selected time histories is improved to have the duration of 15 sec. without significant changes in the other characteristics. A case study of a plane model with 3 lumped masses is done using three time histories, i.e, two selected and one improved time histories. It is found that the improved curve gives almost the same results as the original one and reduces the computer time by about half, whereas two selected time histories give the results with same trend but much different magnitudes each other. It is claimed, however, that the improved time history is not the optimal one, but very economical in practical applications.
