HID(High Intensity Discharge) search lamp for shipment requires a high open circuit and output current compare than vehicle. This paper presents a soft-start open circuit voltage and constant current sequence control method for 2.5[kW] HID search lamp. The proposed method controls the opal circuit voltage and discharge current of HID lamp according to ignition signal with a simple 8-bit micro-processor and PWM device. For the stable control of lamp, micro-processor checks the output voltage and current. And the checked signals are compared with ignition signal and changes the control mode for stable operation. An ignition signal and micro-processor change the control mode from open circuit voltage contort to constant current control. The proposed control scheme is verified from experimental tests of 2.5[kW] HID search lamp for shipment. 본 논문에서는 2.5[kW]급 선박용 HID 탐사등 조명을 위한 Soft-start 개방회로 전압 및 정전류 순차 제어 방식을 제안한다. 제안된 제어회로는 HID 탐사등의 안정적인 점등을 위하여 개방회로 전압과 점등 전류를 순차적으로 제어하는 방식으로, 특히 전원투입 상태에서의 안정성을 위하여 일정한 입력전압에 대해서 Soft-start 기법을 적용하여 개방회로 전압 제어모드로 동작하도록 설계되었다. 또한, 점등개시 신호의 입력에 따라 제어모드를 전압제어에서 전류 제어모드로 변경하여 단일 PWM 제어소자에서 동시에 처리하도록 하였다. 한편, 입력 노이즈 및 개방회로 전압의 검출을 간단한 원칩 마이크로 프로세서로 구현하여, 오동작 및 점등 실패에 대한 강인성을 부가하도록 하였다. 제안된 제어기는 실제 선박용 HID 탐사등의 적용 시험을 통하여 그 안정성을 시험하였다.

Since earlier in 1947 the writer had been devoting part of his time to study alluvial fans in Korea based on his own interest in geomorphology. However, it was in 1958 when a new geography department was set up and the Research Center of National Lands was established in the university of Kyung Hee, the writer started scientific investigation for alluvial fans. The Following alluvial fans have been studied by the writer: those of Mt. Kwanak and Mt. Chungge in 1947; those of Pulkuksa in 1948; those of Suhnamsa, Suh Myun, Pusan in 1950; those of Shindonae, Mt. Kerrong, in summer of 1958; those of Hwaomsa, Kure and Yongsan Myun, Changhung, in winter of 1958. The article is the comparative study of the above mentioned alluvial fans including Suhkwangsa Fan, Chugaryng Rift Valley. Of course this is not the study covering all af alluvial fans in Korea. Within the limits of his surbey, the writer has com to a conclusion which may be helpful for the Korean alluvial fm study. 1. Korean alluvial fans are generally found in rift valleys or basins. 2. They are formed in places of below 220-meter contour line. 3. The slope from fna apex to river valley is 20-40 degree. The slope of fan surface is 5-20 degree, but most of them under 16 degree. A sudden change of slope is taken place or the fan apex and fan center. 4. Hills (100-200m) are developed on the surfaces of alluvial fans. 5. Most of rivers in alluvial fans are geyser rivers. 6. The depth of well : from ground surface to the well water surface is 4-8 m; water depth is 1-2m. 7. Land utilization; cultivated land 30%: non cultivatedland 70%. The area occupied by upland fields is twice of paddy field area. 8. Settlement : agglomerated settlement is developed on the top or the end of fan and surrounded by windbreakers. 9. Farming pattern at the top of fan fields are rectangular and parallel to flumes but at the center of fan, they are irregular and perpendicular to flumes.

Purpose of study; The purpose of this study is specifically classified as two parts. The one is to attempt the chronological annals of Quaternary topographic surface through the study over the formation process of alluvial surfaces in our country, setting forth the alluvial surfaces lower-parts of Han River area, as the basic deposit, and comparing it to the marginal landform surfaces. The other is to attempt the classification of micro morphology based on the and condition premising the land use as a link for the regional development in the lower-parts of Han river area. Reasons why selected the Lower-parts of Han river area as study objects: 1. The change of river course in this area is very serve both in vertical and horizontal sides. With a situation it is very easy to know about the old geography related to the formation process of topography. 2. The component materials of gravel, sand, silt and clay are deposited in this area. Making it the available data, it is possible to consider about not oかy the formation process of topography but alsoon the development history to some extent. 3. The earthen vessel, a fossil shell fish, bone, cnarcoal and sea-weed are included in the alluvial deposition in this area. These can be also valuable data related to the chronological annals. 4. The bottom set conglometate beds is also included in the alluvial deposits. This can be also valuable data related to the research of geomorphological development. 5. Around of this area the medium landform surface, lower landform surface, pediment and basin, are existed, and these enable the comparison between the erosion surfaces and the alluvial surfaces. Approach : 1. Referring to the change of river beds, I have calculated the vertical and horizontal differences comparing the topographic map published in 1916 with that published in 1966 and through the field work 2. In classifying the landform, I have applied the method of micro morphological classification in accordance with the synthetic index based upon the land conditions, and furthermore used the classification method comparing the topographic map published in 1916 and in that of 1966. 3. I have accorded this classification with the classification by mapping through appliying the method of classification in the development history for the field work making the component materials as the available data. 4. I have used the component materials, which were picked up form the outcrop of 10 places and bored at 5 places, as the available data. 5. I have referred to Hydrological survey data of the ministry of Construction (since 1916) on the overflow of Han-river, and used geologic map of Seoul metropolitan area. Survey Data, and general map published in 1916 by the Japanese Army Survbey Dept., and map published in 1966 by the Construction Research Laboratory and ROK Army Survey Dept., respectively. Conclusion: 1. Classification of Morphology: I have added the historical consideration for development, making the component materials and fossil as the data, to the typical consideration in accordance with the map of summit level, reliefe and slope distribution. In connection with the erosion surface, I have divided into three classification such as high, medium and low-,level landform surfaces which were classified as high and low level landform surfaces in past. furthermore I have divided the low level landform surface two parts, namely upper-parts(200-300m) and bellow-parts(${\pm}100m$). Accordingly, we can recognize the three-parts of erosion surface including the medium level landform surface (500-600m) in this area. (see table 22). In condition with the alluvial surfaces I have classified as two landform surfaces (old and new) which was regarded as one face in past. Meamwhile, under the premise of land use, the synthetic, micro morphological classification based upon the land condition is as per the draw No. 19-1. This is the quite new method of classification which was at first att

Korea physiographic province is divided into two provinces which is northern Chugaryung graben zone and southern Chugraryung graben zone. Northern Chugraryung is also divided in to Gema block and Kohan block, and southern Chugraryung dividedinto Han block, Yongnam basin and Honam plain. The above mentioned macro geomorophic units is divided, mainly on the geotectonics. The meso geomorphic units is divided, based upon the regional distribution of topographic characteristic that is plateaus, mountains, mountain range, basins and great plain etc. Micro geomorphic units id into a mountain, a hill, a plain, and a lowland, and then it is formed by selfreliant topographic unit. And micro topographic (fan, peneplain, delta, etc) dealt with a characteristics unit. In this article has a disregarded amallest scale that is included flood plait natural levee, back marsh and oxbow lake etc. Accordingly, it shows macro units are meso units are 5, meso units are 53, micro units are 299. A study method of physiographic provincs prefered to aufsteigende and abstergands methoy. How to organically combine topographic factors can be seen in regional distribution of the peculiar topographic characteristics, for charage teristic of topographic makes a study on the topographic of micro unit such understanding as aufsteigende method. At the same time, since it can be studied systematically from marco unit to micro unit like the absteigende methods, I used both methods. And this establishment of physiographic province based on the scientific method depend on the base map of climate classification. Geology, Soil, Biology. I feel confident that it will be used the basic map for land use map, land classification map, study of geomorphology of Korea. And will be used for study of a topographic standard data.

한국 Pediment 지형의 연구성과에 관한 비판과 문제점

박노식,Park, No-Sik 한국동굴학회 2005 동굴 Vol.68 No.-

It is a wrong decision to use only topographic and geological maps for the study of pediment morphology in Korea. For the study of pediment morphology it is necessary to survey the earth structure by field techniques. In Korea, pediments are mostly found in granite areas with hardrock cover. But, pediments also developed in gneiss areas and what is worse in limestone areas. So, all areas in Korea developed pediment morphology. Only in South Korea pediments show a direction from south to north or from west to east. They developed only in right angles to each other, either parallel or in right angles to the strike, depending on the bedrock structure. Pediments are found in two levels. The upper level pediments are correlated with the lower level erosion surface. Besides this pediments are found in Hoenggye-ri of the Taegwolryong area in a third level 800m above sea level. The pediments developed in basins, at the lower margins of steep slopes dividing three levels of erosion surfaces and around the residual mountains on the erosion surfaces. The first belong to the early stage of pedimentation, the second to the middle stage and the third to the last stage. Also, in Korea monadnock and residual mountain have developed the pediments are correlated the slope of the hinter mountains. Akagki states that the only pedimentation times have been times of arid climate and that they are dissected by gulley erosion with climatic change, but writer's study proves that pedimentation takes place with eustatic movement, reckless defore-station and convectional rain. These facts indicate that the landforms, geological character and process of erosional cycle of the pediments in Korea resemble much those in the Chugoku Mountains of south wertern Japan, but they are larger in scale than those in the Chugoku Mountains. In conclusion, while Akagki emphasizes the geological character and climatic change in pedimentation, the writer studies prove that eustatic movements, especially the sea level rise after the Wurm age are important factors for pedimentation. Besides this the author's studies allow a classification of gentle slopes.

마가복음의 공간 함의 - 신학과 은유

박노식(Park, Roh Sik) 한국신약학회 2014 신약논단 Vol.21 No.4

그리스 비극이 다양한 장소소와 시간소를 사용하여 시공간을 내포하는 은유적 요소와 환유적 요소로 직조된 것처럼 마가복음도 사건들을 의도된 공간에 배열하여 극적 효과를 극대화하며, 새로운 의미를 창출하였다. 마가복음의 저자는 자신의 공동체의 사회 · 심리적 응집력을 강화시키려는 목적에서 사건들의 배열을 전개하였다. 마가복음의 서사 공간은 예루살렘, 갈릴리, 그리고 하나님 나라로 구분할 수 있다. 마가복음에서 하나님 나라 혹은 길이라는 공간은 결코 순수한 지리적 위치 혹은 고정되거나 한정된 장소, 물체의 한계로서 2차원적인 평면적 장소가 아니듯이, 갈릴리는 하나님 나라를 위한 공간 은유로서 나타난다. 마가복음의 갈릴리는 에피소드 자체에서는 닫힌 장소로서 한계 혹은 경계를 암시하는 바로 그 곳을 뜻하지만 사건들의 배열안에서 위치소는 인과관계 안에서 존재적 경험을 확인하게 하는 광대한 ‘바로 그 공간’으로서 공간 은유다. 공간 연구는 결국 해석자의 관심을 실천적인 것에 전이시킨다. 공간은 경험되고 거주적인 차원의 ‘여기’에 연관되기 때문이다: 미래보다는 현재로, 저기 보다는 여기로, 내일 보다는 오늘로. Space represents what we are rooted and can understand who we are. The studies regarding the Gospel of Mark focus on temporal matters and lack concern for critical spatial theory. This study is an attempt to bring a critical social theory of spatiality to elicit theological implications of the Gospel of Mark. This study discusses Mark’s presentation of space by means of structural exegesis of the Gospel of Mark. The narrative space of the Gospel of Mark is divided into three suborders: Jerusalem, Galilee, and the Kingdom of God. The Gospel of Mark preserves a portrait of Galilee as the metaphoric space for the Kingdom of God in that the resurrected Jesus would appear in Galilee and expect there to see his disciples again. The spatial presentation of the Gospel of Mark includes geographical marks to enhance socio-phychological cohesive power of the community and to keep some people holy before God by separating Galilee from Jerusalem. Galilee represents the metaphoric space for reconciliation between Jesus and his followers. Galilee is the spatial metaphor in the Markan narrative structure.

The author of the Gospel of Mark ends his gospel on a note of human failure. Mark 16:8 is the original and intended ending of the Gospel. This is a major literary unit of the Gospel as well as the conclusions of the major works of ancient popular narrative. The Markan original ending is a literary and rhetorical strategy that addresses Christian who are faithful, yet fearful, stumbling, feeling both Jesus absence and the silence of the eyewitnesses formerly among them and awaits a hearing of this new word in the audience ahead of the text. This study aims to identify the specific literary and rhetorical techniques and theological implications of the Markan original ending. The Markan original ending emphasizes the apostolic commission to proclaim the gospel. The words of the final scene in the Gospel of Mark describe an experience past and present. The Markan original ending is designed to be an experience of conflict between the scandal of flight and silence and the fear of proclamation. This study focuses on a dialogue with the women s scandalous actions of flight and silence in the final verse of the Gospel of Mark. The women s flight and silence in Mark 16:8 creates generative potential space between narrative and audience, space in which audience can respond. In response to the shock of realization that the response of flight and silence is utterly wrong, the narrative appeals for the proclamation of the gospel regardless of fear. The Markan original ending provokes the listeners and audiences to reflect on the future response of Jesus followers to the commission to proclaim the gospel.

Proposed about new inverter that can use in PV system in this paper. Multi_level inverter that used inverter makes use of 4 transformers is basis, primary winding of each transformer voltage as can do step_up or step_down to appropriate voltage space tap lake. Put circuit that tap that turn in transformer connects properly according to inhibit signal that sense change of input voltage (output voltage of solar cell place) and transformer secondary voltage controls point of contact of relay so that get into fixed output voltage. As a result, can minimise relative harmonic content despite change width of input voltage are wide because number of output voltage level of multi_level inverter does not decrease. Because proposed circuit manufactures is easy and control is easy and is no burden of cost price rise economically, commercialization expected to do easily and this study examined propriety of action as that compose and experiments proposed circuit.
