        정량적(定量的) 해석(解析)에 의(依)한 함백향사(咸白向斜) 구조(構造) 연구(硏究)

        박인식,민경덕,Park, Rin Sik,Min, Kyung Duck 대한자원환경지질학회 1980 자원환경지질 Vol.13 No.3

        A geologic structure could be formed through various processes, because there are a number of factors which control the deformation of the Earth's crust. In geology, we could call it geological epistemology to describe exactly a geologic structure, and call it geological logics to infer logically the deforming process through which the geologic structure had been formed. Degree of legitimacy of geological logics depends upon the degree of exactness of geological epistemology. This study described quantitatively 3-dimensional Hambaek Syncline through computer analysis, and examined qualitatively into its deforming mechanism based on the results of 3-dimensional analysis of the structure. Input data for the computer analysis are dips and dip directions of bedding planes of the structure. The Hambaek Syncline disclose a minor fold group of NE-SW or NNE-SSW trend and a large scale fold of E-W trend. The conclusions of this study are as follows: (1) The fold of E-W trend is primary fold $(F_1)$ and the minor fold group of NE-SW or NNE-SSW trend secondary fold $(F_2)$. (2) Hambaek Syncline is cylindrical type fold. (3) Apparent axial trace of Hambaek syncline does not coincide with true axial trace. The apparent axial trace is $N70^{\circ}-80^{\circ}W$ in Gohan and Sabuk area, and changes to $N70^{\circ}-80^{\circ}E$ in the westward of the area, while the true axial trace is $N40^{\circ}-70^{\circ}W$ in the former, and $N60^{\circ}-80^{\circ}E$ in the latter area. (4) Westward dipping of axial plane of the minor fold group of NE-SW or NNE-SSW trend can be attributed to simple shear movements along overthrusts. (5) Angle between axial trace and the directional trace of the maximum principal compressive stress $({\sigma}_1)$ may not be perpendicular each other. The angle between them is governed by the following factors; 1) the plunge of fold axis 2) the dip of axial surface 3) cylindrisity (6) The mean axial trace of Hambaek Syncline $(F_1)$ is $N45.6^{\circ}W$, and the directional trace of ${\sigma}_1$ is $N52.4^{\circ}E$ (7) The mean axial trace of the minor fold group of NE-SW or NNE-SSW trend $(F_2)$ is $N21^{\circ}E$, and the directional trace of ${\sigma}_1$ is $N22^{\circ}W$.

      • 900MHz GSM 디지털 단말기용 Si BiCMOS RF송수신 IC개발 (I) : RF수신단

        박인식,이규복,김종규,김한식,Park, In-Shig,Lee, Kyu-Bok,Kim, Jong-Kyu,Kim, Han-Sik 대한전자공학회 1998 電子工學會論文誌, S Vol.s35 No.9

        본 논문에서는 E-GSM 단말기용 Transceiver RFIC 칩 수신단의 회로설계, 제작 및 특성측정을 수행하였다. AMS사의 0.8${\mu}m$ 실리콘 BiCMOS 공정을 사용하여 $10 {\times} 10 mm$ 크기를 갖는 80핀 TQFP 패키지로 제작하였으며, 동작전압 3.3V에서 우수한 RF 성능을 얻었다. 제작된 RFIC의 수신단에는 LNA, Down Conversion Mixer, AGC, SW-CAP 및 Down Sampling Mixer를 포함하고 있으며, 제작된 RFIC의 사용 주파수 범위는 925 ~ 960MHz, 전류소모는 67mA, 최소검출레벨은 -105dBm의 특성을 얻었다. A single RF transceiver chip for an extended GSM handset application was designedm, fabricated and evaluated. A RFIC was fabricated by using silicon BiCMOS process, and then packaged in 80 pin TQFP of $10 {\times} 10 mm^{2}$ in size. As a result, it was achieved guite reasonable integraty and good RF performance at the operation voltage of 3.3V. This paper describes development results of RF receiver section of the RFIC, which includes LNA, down conversion mixer, AGC, switched capacitor filter and down sampling mixer. The test results show that RF receiver section is well operated within frequency range of 925 ~960 MHz, which is defined on the extended GSM specification (E-GSM). The receiver section also reveals moderate power consumption of 67 mA and minimum detectable signal of -105 dBm.

        日帝の朝鮮支配末期における情報ㆍ宣伝政策

        朴仁植(Park In-sik) 가천대학교 아시아문화연구소 2007 아시아문화연구 Vol.12 No.-

        This paper aims at consideration after the China-Japan war outbreak in 1937 about the role of "Choson Central Information Committee" established for management of smooth rule of Choson colony, and warfare. Japan converts Choson rule system with China-Japanese War as the starting point. Surely from this time, Japan was ready in the rule base of ideology about Choson. Japan got the military action to a continent, and the range of international propaganda was also expanded to not only Choson but the China continent, and the neighboring area. And Japan put power into common knowledge of the justification of the imperial management in Choson colonial rule and a continent for brew of international public opinion. The propaganda activity in Japan put an emphasis on the importance of colony Choson which was advance and the supply base of war. The Governor Jiro Minami who arrived at his post just before outbreak of China-Japanese War strengthened the Choson rule policy, and the realization of "Homogeneity of Japan- Choson" and the policy of an Empire subject which are a government idea of Japan were strengthened further. It was made a means to have developed "Emperor's war" and to mobilize people to war, under the slogan of "the Holly War's completion" at the Asia-Pacific war term. As a war execution means of Japan, although "manipulation propaganda" became strong, a series of motions were observed. I think that the actual condition of the propaganda of "Choson Central Information Committee" and the Government-general will be tested by comparison, bearing the upper contents in mind. The propaganda of the Government-general shared mutual recognition of Choson and Japan, and analyzed also about the usage of propaganda of the Government-general and the effect it is going to force participation in the war as an Empire subject's member for a victory.

        중족골 바 형태의 전족부 라커 신발이 하지 근 활성도 및 족저압력 분포에 미치는 영향

        박인식 ( In Sik Park ),정지용 ( Ji Yong Jung ),전근환 ( Keun Hwan Jeon ),원용관 ( Yong Gwan Won ),김정자 ( Jung Ja Kim ) 한국운동역학회 2012 한국운동역학회지 Vol.22 No.1

        The purpose of this study was to evaluate the effects of forefoot rocker shoes equipped with a metatarsal bar on lower extremity muscle activity and plantar pressure distribution. Ten healthy women in the age of twenties were participated in this study as the subjects. All subjects walked on a treadmill (Gait Trainer, BIODEX, USA) wearing normal shoes and metatarsal bar shoes, during which the plantar pressure distribution and muscle activity were measured. Using Pedar-X system(Novel Gmbh, Germany), the plantar pressure was measured for six regions of the foot: forefoot, midfoot, rearfoot, 1st metatarsal, 2-3th metatarsal, and 4-5th metatarsal, and for each sub-region, 4 features such as maximum force, contact area, peak pressure, and mean pressure were analyzed based on the plantar pressure. EMG(Electromyography) activity was measured by attaching surface electrodes to the rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius medial head, and magnitude of muscle contraction was analyzed in IEMG(Integrated EMG) value. The results show that the maximum force, contact area, peak pressure, and mean pressure in the midfoot all increased while maximum force, peak pressure, contact area, mean pressure in the 1st metatarsal and 2-3th metatarsal all decreased when wearing functional shoes. Also, muscle activities in the four muscles were all decreased when wearing the functional shoes. This paper suggests that forfoot rocker shoes equipped with a metatarsal bar can help disperse the high pressure and absorb the shock to the foot as well as give positive influence on gait pattern and postural stability by reducing muscle fatigue during walking.

        総督斎藤実の「朝鮮情報委員会」によるプロパガンダ政策

        朴仁植(Park In-Sik) 가천대학교 아시아문화연구소 2006 아시아문화연구 Vol.11 No.-

        The Governor-general Saito Makoto established "Chosen Information Committee" newly as a mechanism of administration consultation in 1920. The Chosen Information Committee in 1920 was a Governor-general's private government consultation mechanism. This Committee performed the role urged to the Chosen people's attitude transformation in the slogan of assimilation called "Homogeneity" of a ruler-ed as "persuasive communication" in Chosen. The Japanese government not only monopolizes to the information on colony Chosen, Japan, and overseas, but by doing in this way, perfect suppression of freedom of speech was attained. This paper analyzed the feature of the propaganda policy and the rule transformation of a Chosen government-general in the 1920s.
