임진강유역 고구려城의 性格 再考

권순진(Kwon, Soon-jin) 국방부 군사편찬연구소 2012 군사 Vol.- No.83

This is to review the nature of Koguryo’s three fortresses in the Imjin River basin from the two military historical perspectives. First one was based on the period from the last quarter of the 4th century to mid-6th century when Koguryo engaged in offensive operations Horogoroo was located along the attack route of Baekje, thus it contained Baekje’s attack and played a role as an assembly area for the reserve force. Horogoroo and Dangpo fortresses were repaired so that the fortress became strongholds to control surrounding areas and supply bases. While Eundaeri fortress was disused. Second one was based on the period from the second half of the 6th century to the second half of the 7<SUP>th</SUP> century when turned to defensive operations and the battles were stalemated. The three fortresses were vulnerable to attacks because the areas to the south of the fortresses were higher than the fortresses. For this reason, it seemed that Horogoroo and Dang-po fortresses were used as command posts and supply bases during the battles. It seemed, however, that Eundaeri fortress lost its defensive function and Moodeng-ri fort assumed the role of defense.

丙子胡亂 金化 栢田戰鬪 考察

권순진(Kwon Soon-jin) 국방부 군사편찬연구소 2015 군사 Vol.- No.96

This is a study on Gimhwa Baekjeon(栢田) combat during the Manchu Invasion to Choseon(Byeongjahoran, 丙子胡亂). As the Gimhwa Baekjeon combat was a battle that broke out in the whole area of Baekjeon to the south of the former Gimhwahyeon during Byeongjahoran(the Manchu war of 1636), it has been known as the top two combat sites with victory during Byeongjahoran together with the Mt. Gwanggyo combat of Yongin. However, it existed a point that the history of its combat failed to be properly illuminated due to the lack of an interest by both the military and the academic circles. As a result of the research, a name of a battle has been called ‘Baekdong combat’,‘Tapdong combat’, or ‘Gimhwa combat.’ However, it is thought to be likely good to call it as “Gimhwa Baekjeon combat” in the future because of having been the battle that both the armies fiercely fought in the adjacent area, namely, in the whole area of Baekjeon as for a mutual enemy named Cheong(淸). Also, seeing it through many ancient literature records, the battle area is judged to be more appropriate to regard the Baekjeon combat site as the whole area of Baeksubong in Eupnae-ri of the present to the south of the former Gimhwahyeon, and the whole area of Seongju gogae and Chungryeolsa temple, rather than clearly stating it as Baekdong /Tapdong within DMZ(de-militarized zone). Second, examining it in the aspect of the defense deployment in the Hong-myeong-gu army and the Yu-rim army, the Hong-myeong-gu army can be said to have been strong in a will to positively fight with burning the bridges with the desperate mind rather than taking the defensive attitude by entering to be protected by fortress. On the other hand, the Yu-rim army could steer this combat to victory with preoccupying the advantageous defensive position, with installing effective obstacle, with the fire control, and with the deception operation. Finally, it is judged to be necessarily made a battlefield as a site of vivid history with patriotism and a conquest for a national crisis by being imminently preceded a detailed investigation on a battle zone.

高陽 覓節山遺蹟 出土 百濟土器의 紋樣硏究

權純珍(Kwon, Soon-Jin) 백산학회 2007 白山學報 Vol.- No.77

Decoration style of pottery is a form of expression by people lived at those times. So that the pottery of Paekche dynasty may have reflected a distinct life style of a people of Paekche. In site, 27 MNI within 7 types of Paekche potteries were excavated. These decorations in this Moekjeolsan site were made by incised or impressed on wall of potteries. In this paper, I will discuss about decoration styles and techniques of potteries uncovered in Moekjeolsan Site. There are two kinds of pottery decoration styles: type I and type II. The decoration style of type I is alphabet I shape( | ), alphabet X shape(×), triangle shape(⊿󰁈), and bird footprint shape(⫙). Type Ⅱ is bird footprint shape(⫙), four square shape(田), and crossing lines shape(*). Among the potteries, 26MNI were jar, and 1MNI was wan, kind of bowl. 21MNI were incised or impressed on the neck, 3MIN were shoulder, 1MNI was on the body, 1MNI was on the bottom, and 1MNI was unknown part of potttery. In these decoration styles, type Ⅱ shows a lot of variation on design motive of pottery. It is not sure that the variation of design motive on pottery style were related with time of pottery made. In technical aspects of size, decoration skill, portion of vessel, etc, 3 shards of alphabet ‘X’ shape(×), 3 shards of triangle shape(⊿󰁈), and 2 shards of bird footprint shape(⫙) in type I and 4 shards of bird footprint shape(⫙) in type Ⅱ must be made by same potter. These decorations were incised or impressed on outside wall and the bottom of pottery. On four square shape(田) and crossing lines shape(*) potteries, fingerprints and clap-print were remained inside pottery walls. Finally, the reasons for purpose of pottery decorations were re-examined. As a results, specific sorts of pottery were incised or impressed with specific decoration. So I infer that these decorations of pottery were incised or impressed by potters to avoid confusion of sorting pottery when it were fired.

토복령(土茯令, Smilacis Chinae Radix)으로부터 Dioscin의 분리 및 함량분석

서정학,이주미,권순진,장승엽,이경순,손건호,Seo, Jung-Hak,Lee, Joo-Mi,Kwon, Soon-Jin,Chang, Seung-Yeup,Lee, Kyong-Soon,Son, Kun-Ho 한국생약학회 2001 생약학회지 Vol.32 No.2

The methods for isolation and quantitative determination of dioscin, a spirostanol triglycoside, from the roots of Smilax china have been developed. Isolation of dioscin was achieved by silica gel and RP-18 chromatography. The HPLC method used for quantitative determination of dioscin enabled the standardization of the crude drug. It suggests that the content of dioscin in Smilax china should be above 0.01%.

본 연구는 절리암반의 통계적 동질성에 대한 정량적 기준으로 절리의 평면밀도 및 길이를 통시에 고려할 수 있는 통계적 모수인 박스프랙털(DB)의 적용성에 대해 논하였다. 길이분포와 평면밀도를 달리하는 총 129개의 절리연결망에서 박스 집계법을 이용하여 절리의 길이분포와 평면밀도의 변화에 따른 DB의 변화특성을 고찰한 결과 DB는 절리의 방향 또는 절리길이의 표준편차 변화에 영향을 받지 않고 전체절리에 대한 평균 절리길이와 평면밀도에만 영향을 받는다는 사실을 검증하였다. 또한 DB는 절리의 길이와 평면밀도의 함수로써 공학적 지구조구 구분의 정량적 척도로 활용될 수 있음을 입증하였다. 본 연구의 현장 적용성을 검토하기 위하여 도로사면 및 지하구조물에서 박스 집계법을 적용한 사례연구를 수행하였다. 통계적 동질구역 구분에 있어서 일반적인 지질조건와 더불어 기존의 분할표 해석과 본 연구의 방법론을 병행하면 절리의 방향성, 평균길이 및 명면밀도가 종합적으로 고려된 공학적 지구조구의 구분이 가능할 것으로 사료된다. This study addresses the applicability of box fractal dimension, DB, as an index of statistical homogeneity of fractured rock mass. The box-count method's capability in quantifying the combined effect of fracture density and size distribution is examined systematically. Total of 129 two-dimensional fracture configurations were generated based on different combinations of fracture size distribution and fracture density. DB was calculated tor the generated fracture network systems using the box-counting method. It was found that standard deviation of trace length and fracture orientation have no effect on calculated DB. The estimated DB was found to increase with increasing total density and/or mean trace length. To explore the field applicability of this study, the statistical homogeneity of fractured rock mass was investigated at the rock slope and the underground facility using the box-counting method as well as conventional contingency table analysis. The results obtained in this study clearly show that the methodologies given in this paper have the capability of determining the statistical homogeneity of fractured rock mass.

고온용 수분 분리 중공사 복합분리막 개발

본 연구팀은 중공사 분리막(hollow fiber membrane)을 이용하여 발전소 냉각탑에서 배출되는 백연(white flume)을 저감하거나 클린룸에서의 습도를 저감하는 제습 연구를 진행하고 있다. 중공사 분리막 표면을 수분과 친한 친수성 물질로 코팅해주면 수분 기체가 분리막 표면에 흡착되고, 분리막 내외부의 농도차 및 압력차에 의해 수분이 분리막을 통과(확산)하여 최종적으로 수분이 분리막 내부 표면으로부터 탈착되는 과정을 거쳐 수분 분리가 일어난다. 수분 분리 성능을 향상시키기 위해서는 중공사 분리막의 표면을 친수성 물질로 코팅하는 과정이 필요하며, 분리막 표면에 고분자 물질로 코팅하는 박막복합(thin film composite, TFC) 분리막 및 나노입자까지 첨가하는 나노복합(thin film nanocomposite, TFN) 분리막 등의 기술이 연구되고 있다. 본 연구에서는 상온이 아닌 고온에서도 적용할 수 있는 중공사 복합분리막을 개발하고자 한다. 발전소의 백연은 냉각탑 및 스택에서 주로 발생한다. 하지만, 냉각탑 배기가스 온도는 30~40도로 비교적 낮은데 비해, 연돌 배기가스 온도는 85도 이상으로 높기 때문에 연돌에서 발생되는 백연을 저감하기 위해서는 고온용 수분 저감 중공사 복합분리막 개발이 필요하다. 고온용 복합분리막을 개발하기 위해서는 내열성 분리막 지지체 및 코팅물질이 필요하며, 본 연구에서는 다양한 고분자 중공사 분리막 지지체에 대해 열적 특성, 표면 특성, 접촉각, 표면 거칠기 등의 기초물성을 평가하여 고온에서 적합한 지지체 후보군을 선정한다. 또한, 지지체 표면에 고온용 친수성 물질로 코팅하여 TFC 분리막을 제조하고 이들에 대해 온도별 수분 투과도(water vapor permeance) 및 선택도(selectivity)를 측정하여 고온에서의 복합분리막 적용 가능성을 확인하고자 한다.
