장정수 고려대학교 민족문화연구원 2022 民族文化硏究 Vol.94 No.-

This article is to examine the nature of the ‘Punitive Expedition (征討)’ as a part of policy toward nearby Jurchen tribes. The expedition itself was a tough line policy using military might, but its fundamental purpose was to restore ‘pŏnli (藩籬)’, a fence consisted of Boundary Jurchen (pŏnho; 藩胡) tribes to protect Chosŏn from outer Deep-Dwelling Jurchens (深處胡). Boundary Jurchens are seen in the records of the mid-16th century, but they became extinguished in the early 17th century when most of them were subjugated by the Jianzhou Jurchens (建州女眞). The expeditions were launched mostly around the late 16th century, during the reign of Sŏnjo, to prevent these changes and maintain the status quo. This study further investigates the skepticism on the expedition, especially on its effectiveness. Yi Jŏnggu (李廷龜) is one of the ministers who articulated against the expedition, and his arguments shows the difference between the reality and the oughtness. Through his eyes, we can find a transitional link where Chosŏn policy toward Jurchen tribes transforming into interstate policy toward the Later Jin and the Qing. 이 글은 선조대 對女眞 정책의 하나인 征討의 성격을 고찰한 것이다. 정토는 군사력을 동원한 강경책이었지만, 근본적으로는 藩籬를 복원한다는 목적을 가지고 있었다. 번리는 조선의 육진 인근에 거주하던 藩胡 부락들로 구성된 ‘울타리’를 의미했는데, 그 외연의 深處胡를 방어한다는 군사적 의미를 가지고 있었다. 번호는 16세기 중반에 등장하는 개념으로 17세기 초 대부분 建州女眞에 귀속되면서 사라지게 된다. 선조대인 16세기 말에 집중된 정토는 이러한 변화를 거부하고 현상유지를 꾀하려는 의도에서 진행되었다. 이 글에서는 선조대 말 번호를 대상으로 이루어진 정토의 실효성에 대한 회의론을 다룬다. 특히 李廷龜가 일목요연하게 제시한 반대론을 집중 분석함으로써 시행의 당위와 실제를 살펴보았다. 이를 통해서 조선의 대여진 정책이 後金⋅淸에 대한 외교정책으로 전환되는 연결고리의 한 단면을 확인할 수 있다.

This study is to improve the physiological and social enviornment from the visual and mental oppressive feeling, sunshine and viewing of many-storied apartment houses, gets the degree and area of sun shadow to evaluate the sunshine environment with L.D apartment complex at Sangmu New Downtown, Kwangju, analyzes the sunshine enviornment of the areas, analyzes the visual obstacle according to the length and depth of apartment building by calculating the visual angle of each building and then the following results are obtained. (1) The area of sun shadow of many-storied apartment house is greatly influenced by the length, height and depth of apartment and although the pitch of building is appropriate within the distance regulated by Construction Law, the sunshine enviornment is not always good and the building should be arranged not to produce multiple sun shadows. (2) Since the pitch of building for securing the right to sunshine has the permanent sun shadow in low story of the building due to the multiple sun shadow of the adjacent buildings, it is desirable that the right to sunshine is secured by the regulation ofazimuth angle and the consideration of the right to sunshine. (3) The current Construction Law regulates that all residences should have the height less than that of securing the continous duration of sunshine over fixed hours between 09:00 and 15:00 based on winter solstice prescribed by each local construction regulations, but the development and application of evaluation methods for the security of sunshine are required by considering the azimuth angle and altitude of the sun and the whole amount of sunshine of each area. (4) As a result of analyzing the visual obstacle according to the depth and length of apartment building by obtaining the visual angle of each building, the depth of apartment building is 10~12M, the depth of the building : the length of the building is calculated as 1:5 in obtaining the visual obstacle angle within the maximum 27˚ on the axis of the line connecting the center of building and then the appropirate length of the building is 50~60M.

In this paper, it was investigated the responses of six types of the lipid-coated AT-cut quartz crystal resonators to chemical vapour sensors. The responses of quartz crystal coated with phosphatidylgycerol (PG), phosphatidylinositol (PI), phosphatidylethanolamine (PE), Phosphatidylserine (PS), and lipid A( LA) were obtained, at 9 [MHz], for amyl acetate, acetoin, menthone and other organic gases which showed different affinities for each lipid. The identification of odorants depending on the species of lipid used for coation is discussed in terms of the normalized resonant frequency shift pattern.

DGEBA(digly cidyle of bisphenol A) epoxy resin which is used widly for insulation, was com pounded with phenol novalac epoxy resin and PGDE( polygllycol DI-Epoxide) resin the ratio of 8:1:1. Spacimens were made of the compounded epoxy resin by curing at high temperature. The results obtained from investigations of electrical characteristics for the specimens are summarized as follows. 1) When the same thickness of spacimens are applied by AC(60[Hz]valtages, breakdown voltages(V??) have the highest value with Sphere-Sphere electrodes and have the lowest value with Needle-Plane electrodes. 2) On the characteristics of “t-V??” as a parameter of post-curing times, the more post curing time is long, the more V?? is high. 3) When Needle-Plane electrodes are applied by DC valtages, V?? is lower as Needle electrode has positive polarity than negative polarity. 4) V?? of DC is much higher than that of AC, when the same thickness of spacimens are applied by AC(60〔Hz〕) and DC voltages with Needle-Plane electrodes.

We have investigated the dielectric and electrical characteristics of palmitic acid(PA), stearic acid(SA) and arachidic acid(AA) Langmuir-Blodgett(LB) films because these fatty acid systems have a same hydrophilic group and a different hydrophobic one(methylene group or alkyl chain length). In this work, fatty acid systems were used as LB films and the status of the deposited films was confirmed by evaluating the transfer ratio, the UV absorption and the capacitance. The dielectric characteristics such as the frequency-capacitance characteristics and the dielectric dispersion and absorption characteristics of PA, SA and AA through-plane were measured. The relative dielectric constants of PA, SA, and AA LB films were about 3.0-3.6, 2.7-3.2 and 2.4-3.0, respectively. That is, the relative dielectric constants were decreased in proportion to the chain length of methylene group. Also, the dielectric dispersion and absorption of each fatty acid Lb films have arisen from spontaneous polarization of dipole polarization in the range of 10⁴ - 10?[Hz]. And, the conductivity of PA, SA and AA LB films obtained from I-V characteristics were about 9 ×10?, 3 ×10? and 5 ×10?[S/cm], respectively. These results have shown the insulating materials and could control the conductivity by changing the length of methylene group. Also, we have confirmed that the barrier height of fatty acid systems were about 1.32 - 1.40[eV]and the dielectric constant were about 3.0 - 4.2. These values were almost the smae ones obtained from dielectric characteristics.

The sensitive LB films using stearic acid, one of fatty acid, which was fabricated by langmuir-Blodgett(LB) method. Then, the deposition, temperature, and organic a gas response characteristics with respect to different distance of electrode for horizontal direction of sensitive LB films were investigated. The results for this study were revealed as followings : The optimal deposition condition to deposit the sensitive films was obtained from π-A isotherms and the deposition status of sensitive films was verified by the measurement of deposition ratio, UV-absorbance, and electrical properties. The conductivity of sensitive films was about 10-8[S]㎝]. The activation energy for sensitive film with respect to variation of temperature was about 1.0[eV], which was correspond to semiconductor material. The response characteristics for organic gas were confirmed by measuring the response time, recovery time, and reproducibility of the sensitive films to each organic gas. Also, the penetration and absorption behavior of gas molecule were confirmed through the organic gas response characteristics of sensitive films with respect to temperature.

In this paper, lipid LB films such as cholesterol and phoisphatidyl choline were deposited up to 31 layers on the surface of AT-cut quartz crystal mocrobalance by vertical dipping method and horizontal lifting method. ?-A characteristics and deposition status were evaluated by using deposition ratio and SEM. For the films of various layers, the performances as gas sensor were investigated from the frequency response of methyl alcohol and action gas. The results are as follows. (1) Cholesterol's surface pressure is about 30[dyne/cm] and limiting area is about 50[A/mol;ecule]. Phosphatidyl choline's surface pressure is about 15-25[dyne/cm] and limiting area is about 60-80[A/molecule]. (2) The deposition status of LB films can be evaluated from the frequency shift which is proportional to the mass of deposited layers. (3) The higher concentration of methyl alcohol and aceton gas become and the more number layers become, the better frequency response and reappreance are obtained. According to the above results, QCM which was deposited with LB films in this experiment is applicable to the gas sensor.

SNOAM을 이용한 메로시아닌 색소 LB막의 표면구조 및 투과 이미지의 고찰

張正秀,辛薰奎 경일대학교 2001 論文集 Vol.17 No.-

Organic thin-films such as LB films, self-assembled films and evaporated films are interesting for their technological and fundamental application. The spectroscopy of dyes has been a popular subject of study for many years, both theoretically and experimentally. In this study, we will illustrate the topographical structure and optical structure of the merocyanine dye LB films obtained by the scanning near-field optical/atomic force microscopy (SNOAM). SNOAM was recognized as a powerful tool to modify the surface as well as to characterize the topography of the surface at atomic resolution, especially for optical reaction materials. SNOAM images showed that the topographical and optical structures of these films were not only depended on the chemical property but also physical property. In the continuous measurement on these dyes, the appearance of near-field optical transmission images showed a certain dependence on the kinds of dyes and the mutual mixing ratios of dyes. These experimental results suggest that there is a certain kind of interaction between these two dyes.
