김종배 한서대학교 정보산업대학원 2006 국내석사

Even though the life is delicately organized physics and chemistry, it was a just subject of physics and chemistry. However the matter we faced with is depending on finding out how DNA works itself. As this is how the cell molecule analyzes the message of DNA, it makes us understand how it comes into being at first. The study of the history in modern hairstyles can be analogized about the study on DNA, which illuminates how a life comes into being. The original and artistic hairdesign, expressed on a living human body, aims at the scalp and the hair. Arriving at the conclusion that the base of hairdressing is the genesis of the follicle, the requirement of a systematic study about it comes into focus. This is based on genetics and the principle of cell division according to the source of embryology. The characteristics of each one of human beings are verified by differences of genetic codes. These genetics are DNA 's, the core of our humanity containing informations. It regulates a whole of life as well as cell division. The superficial layer of the scalp, which is related to molding a human body, develops from the endoderm of a cell, and the deeper layer of the scalp develops from mesoderm underneath it. A genetic factor of cloning mold has their own characteristics so that it verifies there is no average human beings and exists differences of a genetic code for each person. This genetic factor is the DNA of the core of hunman beings that has information and controls the whole body as well as cell division by protein. In particular, superficial layer, scalp related with human body molding generates at ectoderm and the derma occurs at mesoderm. Blastocoel at the early stage of generation is covered with a lay of ectoderm. Division and proliferation of epithelial cells occur within 2 months of an embryo. Around the end of 3 months, supercilia is produced and the first hair is appeared at the upper lip. This is called as lanugo hair. The hair emerge through an outward travel of them within 4 ~5months of an embryo. lanugo hair is eliminated around 8 months and at the moment of birth, it is replaced with thicker hair. The scalp hair compliments the changing needs of the times and the increasing aesthetic concerns as well as the sexual hair. Therefore the embryological foundation in the hair is very important. The study on the scalp and the follicle which is related to it as an appendage of the scalp builds the foundation of the design of sculpturing a human body as well as an effective hair care. According to the results of the survey, the general characteristics of the subjects were as follows: Out of 864 cosmetology majors in the region of Busan, the female students outnumbered the male students, as the two groups respectively accounted for 84.6 percent(731 students) and 15.4 percent(133). By academic school year, the number of the freshmen was larger than that of the sophomores, since the two groups respectively represented 63.0 percent(544) and 37.0 percent(320). By age, most of the students were at the age of 20 to 22, which accounted for 81.6 percent(705). Those who were at the age of 23 to 30 and represented 11.1 percent(96) made up the second largest group, followed by the 17-19 age group with 5.7 percent(49), the 31-40 age group with 1.2 percent(10) and the 41 and higher age group with 0.5 percent(4). Their scalp tended to be healthy, and they didn't find their hair to be damaged a lot. They attached the most importance to technical scalp management, and they viewed dyeing and discoloring as the primary causes of hair damage. They believed that the proper use of scalp- related products had a good impact on the health of hair, and they perceived that improved scalp could contribute to enhancing the health of hair. Cosmetology majors are customers, and they are the mainstay of future beauty industry at the same time. In beauty education, scalp management is one of holistic curricula that offer both academic and technical education. So the effort by this study is expected to provide information on not only future scalp management but overall beauty industry.

Phenol-formaldehyde 反應의 速度論的 硏究

김종배 全北大學校 1986 국내석사

A kinetic study of the reaction of phenol with formaldehyde has been carried out at temperatures of 65, 70, 75 and 80±0.5˚C. The pH maintained was 1.20, 2.05, 3.10, 6.80, 8.80 and 9.10 by using hydrochloric acid and sodium hydroxide as the catalyst. At pH 1.20, 2.05, 3.10 the rate is found to increase with decrease in pH, but at pH 6.80, 8.08, 9.10 the rate is found to increase with increase in pH. The reaction follows a second-order rate law. The overall rate constant(k) has been resolved into stepwise rate constants(k_1, k_2, k_3). For this purpose the rate equations for the various possible steps have been suggested. The experimental and calculated values of k at various pH and temperature have been found to agree well within the experimental errors. The entropy of activation and Arrhenius parameters for the overall reaction as well as for the stepwise reactions have been calculated. A mechanism conforming to the energies and evtropies of activation of the reaction has also been suggested.

김종배 한양대학교 공학대학원 2014 국내석사

본 논문은 애자 청소를 통하여 애자의 코로나 및 절연 저하를 예방하고 양질의 전력을 안정적으로 공급하기 위한 방법을 제시한 논문이다. 기존 애자 청소방법은 고전압 고소의 위험한 환경이므로 정전상태에서 실시를 해야 하기 때문에 사회적으로 기피현상과 맞물려 전문 인력의 확보가 어렵다. 기존의 자기세척은 직접전차선에 접근하여 애자를 헝겊이나 세척포로 닦아 세척 하였다. 그러나 애자의 내측이나 홈 등의 미세한 틈을 세척하기 쉽지 않아 많은 시간과 비용 소요가 되었다. 또한, 기존의 물을 이용한 주수식 세척은 많은 양의 물을 사용해야 하기 때문에 전차선로 주변에 물 공급이 원할 하여야 하며 수압이 약해 많은 양의 세척제가 이용되어 환경오염 문제를 야기 시킨다. 이러한 문제점들로 인해 기존 애자 세척방법은 여러 가지 문제점이 있었다. 본 논문에서는 애자의 종류 및 기존의 애자세척 방법 및 문제점에 대해 살펴보고 위와 같은 문제점들을 해결하기 위한 애자세척 방법인 고수압분사기를 이용한 고압압축세척방식을 제안하였다. 제안한 방법으로 공항철도 구간의 애자 청소를 통하여 애자의 오손으로 인한 애자의 코로나 현상을 방지하고 인력과 경비 절감의 효용성을 제시하였다.

김종배 檀國大學校 大學院 1992 국내석사

最近 産業의 發展과 더불어 增加하는 産業廢水 및 生活下水에 의한 水質汚染은 날로 심각해져 이에대한 對策이 時急하다. 活性슬러지(activated sludge)工法으로 處理된 반송슬러지를 이용하여 廢水중에 包含되어 있는 有機物을 分解하는 生物學的 處理方法으로 有機物이 生物學的으로 分解될때 時間에 따른 生物學的 酸素 要求量을 測定함으로써 分解反應에 대한 速度常數(K)를 구할수 있으며 이를 실제 廢水處理 工程에 適用시킴으로서써 廢水處理에 있어서 時間과 經費節減의 效果를 期待 할 수 있다. 本 硏究에서는 Cu(Ⅱ), Zn(Ⅱ)의 이온을 含有한 重金屬 廢水에서 檢定物質로 사용한 아닐린이 分解될때 時間에 따른 生物化學的 酸素要求量을 계산하였다. 이때 重金屬의 濃度를 Cu(Ⅱ)이온은 0.1~10ppm, Zn(Ⅱ)이온은 0.1~10ppm으로 變化시켰다. 時間에 따라 測定한 BOD값을 다양한 理論的 方法에 適用시켜 速度常數(K)를 算出하여 比較分析한 후 實驗값에 대한 誤差가 가장 작은 最適의 理論的 方法을 제시하고 重金屬 濃度 增加에 따른 아닐린 分解 程度를 알아 내고자 하였다. 實驗結果 각 理論的 모델에 의해 速度常數(K)를 算出한 結果 實驗값에 대한 理論값의 絶對平均偏差는 대수법은 17.4%, 모멘트법은 56.2%, 토마스법은 24.0% 였다. 誤差가 가장 작은 대수법으로 구한 速度常數는 檢定試驗에대해 0.25(day^(-1)), Cu(Ⅱ)를 含有한 경우 0.14 ~ 0.07, Zn(Ⅱ)를 含有한 경우 0.09 ∼ 0,06(day^(-1))과 같이 나타났다. 重金屬濃度가 增加함에 따라 아닐린의 分解를 沮害하는 정도는 儉定物質에 대한 速度常數로 비교했을 경우 Cu(Ⅱ) 0.1ppm:44%, 10ppm:52%, 100ppm:72%, Zn(Ⅱ) 0.1ppm:64%, 1ppm:72%, 10ppm:76%로 濃度 增加에 따라 增加 하였으며 生沕學的酸素要求量(BOD) 데이타로써 絶對誤差를 計算한 값과 같은 傾向을 보였다. The water pollution problem caused by waste water industrial process and households is increased day by day. Therefore it is in urgent need of the countermeasures. In one of them, when organic material is biologically divorced from the wasre water including heavy metal by using the recycle sludge of the place dealing with waste water, we can calculate the reaction rate constant(K) by measuring BOD per unit time, and expect the effects of time and cost reduction by applying to the real waste water treatment processes. In this study, BOD per unit time was determined for the changing of the concentration of heavy metal (Cu : 0.l∼l00ppm), (Zn(Ⅱ) : 0.1∼10ppm)when microbe divorces Ani1ine in waste water including ions of heavy metals Cu(Ⅱ), Zn(Ⅱ). From these results, it was proved that the Aniline divorce was inhibited by the concentration of heavy metal, then the reaction rate constant was calculated by the regressing the measured BOD data using the theoretical methods. The optimal theoretical methods were indicated by the comparing of the each absolute average deviations of the theoretical values obtained from each method for experimental data. As a result, Logarithm method was 17.4%, Moment method 56.2%, Thomas method 24.0%. When the reaction rate constants were decided by Logarithm method, it was 0.25(day^(-1)) for aniline, 0.14∼0.07 for including Cu(Ⅱ) and 0.09∼0.06 in the case including Zn(Ⅱ). When the degradation rate of the sample not including heavy metals was compared with that of the sample including heavy metals of Cu(Ⅱ) . Zn(Ⅱ), the degradation rate of aniline had interrelationships with the concentration of heavy netals such as(Cu(Ⅱ) 0.lppm : 44%, 10ppm : 52% l00ppm : 72%, Zn(Ⅱ) 0.lppm : 64%, lppm : 72% l0ppm : 76%). Like that, it appeared that the degradation rate of aniline inhibited, and it shows the tendency that the inhibition ratio was similler to the values of absolute-average deviation which was calcuated from BOD data.

김종배 명지대학교 대학원 2001 국내석사

높이차이가 있는 배관에서 냉매충전량 변화시 모세관 팽창장치를 가진 냉동기의 성능에 관하여 연구하였다. 실험에 사용된 모델은 모세관 팽창장치가 장착된 분리형 에어컨이며 실내기 모델은 MPA712G, 실외기모델은 MPC80Al으로 동일모델은 아니나 비슷한 용량의 실내외기로 구성하였다. 실험장치에 사용된 냉매는 R-22(CHClF₂)이며 냉방능력, 전력소모량, 성능계수, 냉매압력, 냉매순환량, 증발기의 과열도 그리고 증발기내 냉매의 온도분포를 이용하여 냉동기 시스템의 성능에 관해 연구하였다. 냉매충전량 및 실내외기의 설치 높이 변화에 따른 냉동기 시스템의 성능은 적정냉매충전량에 가까워질수록 냉방능력이 증가하다가 적정냉매충전량 이후 냉방능력이 감소하였으며 실내기 기준으로 실회기의 설치높이가 높을수록 적정냉매충전량은 감소하였고 실외기가 실내기보다 낮은 곳에 위치하였을 경우에는 적정냉매충전량이 수평으로 설치되었을 때보다 증가하였다. 반면에 냉방능력은 실내외기의 높이차이에 대해서 큰 변화를 보이지 않았다. 냉동기 시스템의 고압 즉 응축압력이 증가할수록 냉동기 시스템의 전력소모량이 증가하였으며 냉방능력 전력소모량과 밀접한 관계에 있는 성능계수는 냉방능력의 경향과 유사하였다. 증발기 입출구 온도의 차로 나타낸 증발기의 과열도는 적정냉매충전량 이전의 양(+)의 구간이 적정냉매충전량 이후인 음(-)의 구간에 비해 급격히 감소됨을 알 수 있었다. 적정냉매충전량을 전후하여 냉방능력이 감소하는 원인에 대해 설명할 수 있는 증발기내 냉매의 온도를 증발기 pass를 따라 측정해 본 결과 냉매충전량이 적정냉매충전량 보다 과소할 경우에는 증발기에 유입되는 냉매의 온도는 낮지만 증발기에 유입되어서 바로 기체상태로 증발해 버리면서 증발기의 평균온도를 상승시키며 냉매충전량을 서서히 증가시킬수록 증발기에 유입되는 냉매의 온도는 상승하지만 증발기내에서 낮은 온도상태로 유지되다가 증발기 하류에서 상변화를 일으킨다. 반면에 냉매충전량이 적정냉매충전량보다 과다한 경우 냉매가 증발기에서 모두 증발하지 못하고 습증기 상태로 유지되었다. The effect of the pipe-connection height-difference and the amount of refrigerant charged on the performance of refrigeration systems with capillary-tube-expansion device was studied. Iindoor unit model of split type air-conditioner is MPA712G and outdoor unit is MPC80A1, each model is not same but experimental system composed of similar capacity indoor unit and outdoor. The refrigerant commonly used in these system is HCFC-22. Performance of air-conditioner used of cooling capacity, coefficient of performance, input power, refrigerant pressure, mass flow rate, degree of superheat and temperature profiles of evaporator were studied. As the height of outdoor unit(reference indoor unit) is increased, the mass of charged refrigerant is decrease. and as the height of outdoor unit(reference indoor unit) is decrease. As a result of high pressure of refrigerant, condensing pressure, is increased input power of air-conditioner is increased. As a result of temperature profiles of evaporator, undercharging results in wide region of superheat vapor of the refrigerant in the evaporator, overcharging results in high temperature of liquid refrigerant in the evaporator and refrigerant threads through evaporator path in liquid-vapor condition.
