The scope of this thesis is restricted to as follows. First, legislative precedents, doctrines, and cases relating to indirect infringements on a patent right in leading countries are studied. Second, based on Article 127 (Acts Deemed to be Infringement) of the Korean Patent Law, the disputing cases relating to indirect infringements on a patent right are examined. Third, the shortcomings in recognition of the protection scope in indirect infringements on a patent right are considered, and an improved model for determining indirect infringements is suggested. The information in this thesis is obtained by searching the CD-ROMs of legislative precedents and the patent related internet-site such as a patent office or a court of law in each country. The contents of this thesis are as follows; In chapter 2, prior to referring to infringements on a patent right, the interpretation of the scope of a patent claim and the related principles are described, in order to understand the scope of a patent right. In chapter 3, in order to understand the concept of infringements on a patent right, the significance of the patent infringement, the infringement types, and the basic principles and methods for judging the infringement are roughly described. In chapter 4, the significance of indirect infringements on a patent right and its purpose are observed, and compared with foreign legislative precedents. Further, the requirements for establishing indirect-infringements, the timing of patent infringement decision, and the burden of proof are described, and then the related cases in foreign countries and our country are analyzed. In chapter 5, the civil and criminal remedies against indirect infringements on a patent right are described. In chapter 6, problems resulted from the indirect infringements are studied. Finally, in chapter 7, subject matters are collectively analyzed, important contents are summarized, and one model for determining indirect infringements on a patent right is suggested by scrutinizing the determining factors of the indirect infringements step by step.

I analyze the dynamic relationship between stock returns and investors behavior in this paper. For the purpose of the paper, daily KOSPI returns are decomposed into two parts. Rate of return on non-trading time and rate of return on trading time. Rate of return on non-trading time is measured by the closing price of the previous day and the opening price of the current day. And rate of return on trading time is measured by the opening and closing prices of the current day. Rate of return on non-trading time are assumed to reflect global economic information, and rate of return on trading time, domestic or local information. The subject of my study was analyzed by 4 periods of terms. Firstly total period of investigation (January 2002~September 2010), Secondly before period of short sale prohibition (January 2002~September 2008), thirdly during the period of short sale prohibition (October 2008~May 2009), lastly after period of short sale prohibition released. Major results are as follows: Foreign investor’s behavior has an effect on the rate of return on non-trading time than the rate return on trading time through all of 4 periods. Individual investor’s behavior, however, has little effect on the rate of return on non-trading time during total period and period after short sale prohibition released. The results are different before period short sale prohibition and during the period of short sale prohibition. And daily rate of return on foreign exchange rate are measured by the closing price of the previous day and the closing price of the current day. The daily rate of return on foreign exchange rate has not an effect for foreign and individual investors. The reason is that foreign investors invest only for the purpose of capital gain except foreign exchange profit. Consequently, forecast error variance decomposition shows that variance explanation power of foreign investors is higher in returns of non-trading time rather than in returns trading time. And the variance explanation power of individual investors is higher in returns of trading time rather than in returns of non-trading time. It implies that foreign investors’ employ dynamic hedging strategies and give more weight to global economic information rather than to domestic information. We conclude that investment behavior of foreign investors and domestic individuals is based on different economic information. This paper’s findings are consistent with the economic situation that the Korean capital markets have faced since the period of short sale prohibition released at the end of May 2009. 우리나라 주식시장이 1992년 외국인에게 투자가 허용된 이후 1997년말 외환위기를 겪으면서 커다란 전환점을 맞이했고, 2008년 8월 미국발 서브프라임 모기지의 부실 및 리먼브라더스 파산사태로 비롯된 미증유의 글로벌 금융위기를 맞이하여 또 한차례 홍역을 치렀다. 이러한 역경을 극복하는 과정에서 우리나라 주식시장은 거시적인 면에서 두 가지 변화를 가져왔다. 첫째는 우리나라 주식시장이 세계금융시장 흐름에 동참하게 되었다는 점과 둘째는 외국인 투자유치를 위한 투자제한의 철폐와 투자환경 개선 등으로 외국인의 투자비중이 크게 증가하였다는 점이다. 여기에 IT 및 정보통신기술의 발달로 국내외 경제 상황에 대한 주식시장의 정보 효율성이 크게 높아진 상황이다. 본 연구는 주식시장의 일별 수익률을 외국의 정보가 주로 반영되는 비거래 시간대의 주가 수익률과 국내 경제 정보가 주로 반영되는 거래 시간대의 주가 수익률로 구분하여 투자 주체의 역동적 상호관계를 분석하여 투자 주체의 투자행태에 대하여 실증적으로 분석한 연구이다. 또한 일별 외환 수익률이라는 새로운 변수를 설정하여 이 변수가 각 투자주체의 투자행태에 미치는 영향, 특히 외국인 투자자에 미치는 영향을 실증적으로 분석한 최초의 연구다. 또 투자 주체별 순매수비율을 활용하여 비거래 시간대 및 거래 시간대 수익률과 어떤 관계를 갖는가를 실증적으로 분석한 연구이다. 2002년 1월부터 2010년 9월말까지의 한국증권거래소(KRX)의 자료를 이용하여 일별 주가 수익률(비거래 및 거래 시간대 주가 수익률) 및 투자 주체별(외국인 및 개인) 순매수비율을 분석하고 동기간 동안의 국내 외환시장에서 거래된 원 달러 환율자료를 한국은행(BOK)으로부터 수집하여 일별 외환 수익률을 계산하였다. 이러한 분석과정을 거쳐 일별 주가 수익률, 일별 외환 수익률, 외국인 순매수비율 및 개인 순매수비율이 투자주체의 투자행태에 어떤 영향을 미치는가를 살펴보았다. 우선 연구대상 全期間에 대한 분석을 하고 공매도 거래 금지조치 以前 기간(2002.1월~2008.9월), 공매도 거래 금지기간(2008.10~2009.5) 및 공매도 거래금지 해제 以後(2009.6~2010.9)등 4기간으로 나누어 분석하고 그 결과를 살펴보았다. 첫째, 외국인 투자자는 여러 요인의 영향을 받고 있지만 특히 당일 거래 시간대 수익률 보다는 비거래 시간대 수익률에 더 크게 정(+)의 영향을 받는 것으로 나타났다. 이러한 결과는 외국인 투자자는 국내의 경제 상황 변화보다는 외국의 경제 상황에 민감하게 반응하는 투자행태를 취하는 것으로 분석된다. 그리고 공매도 거래 금지기간과 공매도 거래 금지조치 해제 후 기간에 대한 분석에서 비거래 시간대 주가 수익률의 설명력이 훨씬 더 높아진 것으로 나타났다. 둘째, 개인 투자자 역시 여러 요인의 영향을 받지만 비거래 시간대 수익률과 거래 시간대 수익률의 각각 한 단위 충격에 대하여 즉각적으로 부(-)의 반응(순매도)을 보이고 있으며, 거의 동일한 수준을 나타내고 있으나 거래 시간대 수익률의 설명력(17.77%)이 비거래 시간대 수익률의 설명력(16.53%)보다 약간 높다. 개인 투자자는 국내 경제 정보에 의존하는 거래행태를 보이는 것으로 볼 수 있다. 셋째, 일별 외환 수익률은 외국인 투자자가 우리나라 주식시장에 투자하는 중요한 변수로 상당한 영향을 미칠 것이라는 당초 예상과는 달리 비거래 시간대 수익률 및 거래 시간대 수익률과 비교적 큰 폭의 부(-)의 관계를 갖는 것으로 분석되었으며 외국인이나 개인 순매수에 미치는 영향도 미미하였다. 다만 글로벌 금융위기 이후 외환 수익률의 영향은 그 이전보다 절대적 크기는 작지만 공매도 거래 금지기간에는 상대적으로 설명력이 훨씬 높아졌으며 충격에 대한 반응도 더 커졌다. 본 연구의 의의는 첫째, 우리나라 주식시장에 외국인 투자가 완숙기에 접어든 2002년부터 2008년 8월 이후 글로벌 금융위기의 대변혁을 겪는 과정에서 최근의 외국인 및 개인 투자자들의 투자행태를 분석해 보았다는 점과 둘째, 외국인 투자자에게 상당한 영향을 줄 것으로 예상한 일별 환율 수익률이 투자자의 투자행태에 미치는 영향을 최초로 분석해 보았다는 점이다.

In the dissertation, the network in North Korea in the fields of information and communication is analyzed and the plan to modernize the network is proposed. To establish a plan, this study has been centered on how and with what mechanism to construct an infrastructure of communication in North Korea, assuming that the reachable target area as the potential area for communication demands is the economical privilege districts. First of all, we analyzed the communication equipment and the level in North Korea using ITU data and documents. And we improved exactness of discussion by analyzing the case of Germany having gone through the same process. The improved plan by new investments other than the replacement for the existing facilities is suggested and the plan will make it easier to change to the Information Superhighway Network. The study is very important in th point of view as follows: assuming that the economic development of North Korea in Korea Peninsula is very important to unify, it is necessary that the economical level of North Korea reaches that of a developing country urgently. To do it, construction of a communication infrastructure is the most considerable matter. The present level of communication infrastructure in North Korea is 5.3% of South Korea for PSTN, 1% for International telephone lines and 50% for the automatic rate. Signal method in North Korea is R2 in domestic and is NO.5 for international. And mechanical and magnetic exchanges are used such as Crossbar, S-12, etc. inside domestic and an electronic mode E10B for international and the digital rate is 5% and the transmission method is asynchronous. For modernization of the network in East Germany corresponding to the level of the network of West Germany, the "Telecom 2000" program was carried out. "Overlay Network" construction was carried out by 4 steps ; long distance digital network, district digital communication network, local area construction and ISDN introduction, and narrow band ISDN service. "Turn-key" project was the plan to construct rapidly the telephone network connecting the end subscribers. And "Urgent temporary measures" included the installation of telephone switch boards in container style, the operation of tele-office, and the diversion of the special telecommunication network to the urgent public affairs. Most goal or above was carried out until 1997. The important instructions from Germany are to construct the most reasonable networks in North Korea and that the three steps are necessary : urgent network constructions, network expansions and stable operation of networks. Network construction is to supply the basic and general services throughout the country and the required expanse and the investment capital should be prepared. In the strategy for the network construction, Gaesung is chosen as communication model area, which is most achievable and have the most potential communication demand and the best geometric adjacency and accessibility. And the communication demand is estimated based on the economical growth of North Korea and the increase of the population and the number of families. The potential demand not supplied during 1993 to 2000 is 1,064 lines and the supply rate on demand is about 50%. The estimating result of the future telecommunication demands is that telephone supply rate per 100 peoples is 25.93% in 2005 and 51.93% in 2012. And the estimating result shows 2.92 million lines in metropolitan and economic special districts which are high density potential area, 2.19 million lines in medium and small cities and domestic consumption industrial areas, and 0.89 million lines in other areas. Total potential demand is estimated 6 million lines. For the network modernization, the appropriate model for fixed telecommunication networks, main telecommunication networks, subscribe networks and wireless networks are proposed. Goals for each model are established as follows. First, in fixed telecommunication networks, base year for network modernization is determined 2004 and the final target year is determined 2012. Tasks and procedures driven during this period are established : in 2012, telephone supply rate will be 56.93% compared to the 5.93% presenting rate and the digital network construction will be completed from the analog network. The proposal to arrange Numbering system to use efficiently the number resources is the integrated numbering system used in 011-069 number series, which assigns the six large areas in North Korea, different from the numbering system in South Korea. Under he hypothesis that the unification will be recently, the plan to assign the reserved number series(07, 08, 09) of South Korea to the areas in North Korea is proposed. Second, the main telecommunication networks are designed as "X" crossed between the Gaesung-Shineujoo axis and Haejoo-Cheongjin axis centered on Pyongyang. According to the population distribution and the economical environmental, 12 main nodes and 33 regional nodes per the district are determined. The plan to construct High speed main telecommunication network throughout North Korea is proposed. The physical network structure for connecting between main nodes is proposed in 2.5Gbps or 622Mbps and for the links between the regional nodes the structure is in 622Mbps or 155Mbps. Third, the construction for high speed subscriber network as the most expanse telecommunication infrastructure will be carried out in four areas considering the geometric properties and the population distribution. The development for telecommunication services is proposed by four steps : fundamental stage(PSTN + ADSL), expansion stage(ADSL + FTTO), maturation stage(FTTC + FTTO), completion stage(FTTO + FTTH). Particularly, in the construction for fiber-optic cable subscribe networks, a star and point to point mode structure considering the regional properties of North Korea and the economic effects is proposed as the most efficient network mode. Fourth, in wireless telecommunication network construction, a grid model connecting the south-north direction between Gaesung-Rajin and the east-west direction between Shineujoo-Wonsan is proposed. As an alternative plan, microwave network and telecommunication construction is suggested using the Moogunghwa satellite offered the telecommunication and the broadcasting service over the Korean Peninsula. In the dissertation, the strategies for the wire and wireless telecommunication construction are studied. In the future, Expert group survey using the Analytic Hierarchy Process and the plan for a digital radio and television broadcast and a satellite broadcast will be studied. And the standardization is necessary. To realize the proposal, the joint research with North Korea experts should be performed.

보행자 보호를 위한 Hood Lifting System알고리즘에 관한 연구

The aim of this study is to develop an impact recognition algorithm in smart bumper for pedestrian protection. This study is motivated by recent activity to improve safety conditions for pedestrians. All over the world today, injuries and fatalities from road accidents are a significant problem, especially encountered by pedestrians. So many countermeasures, e.g... seat restraints and air bags or stiffened carriage frames, provide considerable levels of protection for car occupants; however, no such protective measures currently exist for pedestrians. Inspired from the successful and effective applications of occupant air bag systems, this study aims to develop similar devices for pedestrians. These active pedestrian protection systems deploy a safety feature such as an external air bag when a pedestrian is hit by a vehicle. Most of the fatal accidents between car and pedestrians prove deadly because of the head-to hood impact. Mostly it is not the impact with the hood itself which proves deadly(because the hood is deformable enough to dampen the impact), but rather the presence of stiff components under the bonnet, whether the spring tower, the engine top or the battery. The head collision is caused after a human leg contacting with the front bumper induces a body rotation. Therefore, the deployable safety device is provides a cushioning surface for the pedestrian head during impact with vehicle hood or bonnet. The accelerometer application is actively considered, recently. So, in this paper, the accelerometer mounted on the inner side of bumper are used to measure the impact data from an impact event. Because the indistinguishable of the surrounding thing and man is impossible, the method recognizing additionally is needed for the data of an impact. The additional method recognizing a man as a temperature by using the infrared sensor was introduced.

경사진 평판에서 다공물질 표면처리가 증발열 전달에 미치는 영향에 관한 실험적 연구

이재완 國民大學校 大學院 2004 국내석사

물의 잠열을 이용한 증발냉각 기술은 응축기나 냉각탑, 증발식 냉각기, 흡수식 냉동기에 적용되어 적은 양의 추가적인 에너지 투입으로 효과적인 냉각성능을 발휘할 수 있기 때문에 기존 시스템에 활발히 응용되고 있다. 증발냉각 기술은 작동기기 표면의 젖음성이 중요한 인자로서 젖음성의 향상은 증발면적을 증가시키고 수막의 두께를 줄임으로써 열저항을 감소시키기 때문에 증발냉각 성능의 향상으로 이어진다. 기존의 친수성 처리로 표면의 젖음성을 향상시키는 방법은 수평 표면에서는 일반 표면에 비해 젖음도를 효과적으로 증가시키지만 경사진 표면에서는 리블렛 유동 형태를 갖기 때문에 그 향상 정도가 미약하다. 그러나 다공성 물질 코팅은 경사진 표면에서도 모세관 현상에 의해 습표면을 얇은 액막 형태로 만들 수 있기 때문에 증발량의 수배 정도의 유량만으로 효과적인 젖음도 향상을 얻을 수 있다. 경사진 평판에서 표면 특성에 따른 젖음도는 일반 표면에 비해 친수성 폴리머로 코팅하였을 때 137% 향상되었고, 다공 물질로 코팅하였을 때 230% 향상되었다. 이러한 젖음도 향상으로 인하여 잠열전달량은 각각 38%와 73% 향상되었다. 잠열전달량 증가로 인한 표면으로부터의 총열전달량은 일반 표면에 비해 친수성 폴리머로 코팅하였을 때 28% 향상되었고, 다공물질로 코팅하였을 때 53% 향상되었다. 이와 같이 젖음도 향상은 열전달 성능의 향상으로 직결되고, 기존의 친수성 폴리머 코팅보다 다공물질 코팅이 열전달 성능 향상에 효과적임을 보았다. Falling film heat transfer has been widely used in many applications in which heat and mass transfer occur simultaneously, such as evaporative coolers, cooling towers, absorption chillers, etc. In such cases, it is desirable that the falling film spreads widely on the surface forming thin liquid film to enlarge contact surface and to reduce the thermal resistance across the film and/or the flow resistance to the vapor stream over the film. In this work, the surface is treated to have thin porous layer on the surface. With this treatment, the liquid can spread widely on the surface by the capillary force resulting from the porous structure. In addition to this, the liquid can be held within the porous structure to improve surface wettedness regardless of the surface inclination. The experiment on the evaporative cooling of an inclined surface has been conducted to verify the effectiveness of the surface treatment. It is measured that the evaporative heat transfer increases about 50% by the porous layer treatment as compared with that from original bare surfaces.

이재완 朝鮮大學校 産業大學院 2001 국내석사

The purpose of this thesis was to investigate the welding characteristics and the fatigue crack propagation behavior of titanium, commonly using power station, aircraft and ship. The experimented material was TIG welded in order to look over the characteristics according to the notch position and compare with other materials. We compared and reviewed the fatigue crack propagation behavior of nonwelded base metal and welded specimens having different notch position to evaluate the fatigue crack propagation behavior by welding condition. From these test, we reached conclusion as followings ; 1. The tensile strength and elongation of the 4 pass welded specimens was shown about 10% and 30% higher than those of the 7 pass welded specimens at the same welding conditions. Also, the more shield gas and the lower natural cooling time, the higher tensile strength but the lower elongation. 2. The absorption energy of the 4 pass welded specimens was decreased about 50% more than that of the 7 pass welded specimens, and the more shield gas, the higher impact absorption energy value. The higher hardness, the lower pass, but the natural cooling time almost had no relation to the hardness. 3. The fatigue life was shown higher as following the order, boundary zone > HAZ ) welding zone > base metal. Especially the fatigue life of boundary zone notched specimen was shown 700% higher than that of base metal. 4. The initial fatigue crack propagation rate is slower in this order, boundary zone < welding zone < HAZ < base metal. Especially boundary zone's growth speed is slower about 30 times than base metal's.

후방추돌시 좌석등받이 강도와 목 상해 상관관계에 대한 실험적 연구

이재완 漢陽大學校 産業經營大學院 1998 국내석사

자동차의 좌석은 충돌, 전복 등의 사고시 상해의 최소화를 위한 안전성 확보가 필수적으로 요구되며, 특히 후방추돌시 탑승자의 목상해는 좌석의 특성에 따라 크게 좌우된다. 사람의 머리는 해부학적으로 굽힘(flexion), 젖힘(extension), 회전(rotation) 등의 운동이 가능하며, 후방추돌시 탑승자는 머리의 젖힘에 의한 목 부상이라 알려져 있다. 따라서 후방추돌시 좌석등받이 강도와 목 상해의 기본적 상관 관계의 이해를 통해 탑승자 보호 및 좌석설계의 기본 개념을 확보하기 위하여 미국 연방 자동차 안전기준 제301조(FMVSS 301)의 시험속도에 준하는 후방추돌 모의시험(sled test)을 실시하여 그 결과를 분석 고찰하였다. 좌석등받이 강성과 탑승자 목 상해의 상관 관계를 파악하기 위하여 첫째, 동일 좌석에 대한 속도별 시험과 둘째, 좌석등받이 강성(등받이 변형각도) 변화에 대한 충돌모의 시험을 각각 5회 실시하였다. 속도별 후방추돌 시험결과 속도가 증가함에 따라 하중과 모멘트가 증가하는 경향을 보였다. 인장, 압축, 전단하중 및 굽힘 모멘트는 임계 상해기준 곡선보다 매우 낮은 값을 보였으나 모든 속도에서 젖힘 모멘트는 상대적으로 높은 값을 나타냈다. 젖힘 모멘트가 모든 속도에서 목에 심각한 상해가 되는 임계 상해기준값 보다는 적지만 목의 심한 젖힘에 의한 휩레쉬(whiplash) 상해 가능성은 충분히 있음을 확인했다. 동일한 시험속도에서 등받이의 강성(변형 각도)변화에 대한 시험결과 인장, 압축, 전단하중, 굽힘 및 젖힘 모멘트 모두 임계 상해값 보다 낮게 측정되었으나, 젖힘 모멘트는 상대적으로 매우 높아 목의 심한 젖힘현상에 의한 상해 가능성이 있는 것으로 평가되었다. 또한, 젖힘 모멘트는 등받이 각도 변화에 따라 차이를 보이고 있으므로 좌석의 설계시 머리지지대, 등받이 강성 등을 적절하게 최적화 함으로써 목의 심한 젖힘 현상, 즉 젖힘 모멘트를 최소화할 수 있다.
