  • 실내공간에서 인간의 쾌적감 및 불쾌적감 등의 감성을 측정하기 위하여 뇌파(EEG)측정을 많이 사용하고 있으나, 뇌파(EEG)측정은 접촉식으로써 실험에 제한적이다. 그러나 진동이미지기술은 웹캠 카메라를 이용하여 인간의 감성을 측정할 수 있는 비접촉식 방법으로써 실내공간에 적용하기에 적합하다고 판단된다. 따라서 인간의 감성을 측정할 수 있는 접촉식인 뇌파(EEG)와 비접촉식인 진동이미지기술의 상관변수를 도출하고자 한다. 본 연구에서는 소리크기 60[dB] 및 90[dB]과 로즈마리 및 쟈스민 향기에 대한 피험자의 뇌파(EEG)와 진동이미지기술의 상관분석을 하였다. 피험자는 건강상태를 점검하여 대학생 남자 3명으로 선별하여 10회 반복 실험하였고, 실험기간은 약 한 달간 진행되었으며, 측정실의 조건은 온도 25[$^{\circ}C$], 상대습도 50[%], 조도 1.000[lux] 및 기류속도 0.02[m/sec]로 하였다. 뇌파(EEG) 23가지 지표(절대${\theta}$, 상대${\theta}$, 절대$S{\alpha}$, 상대$S{\alpha}$, 절대${\alpha}$, 상대${\alpha}$, 절대${\beta}$, 상대${\beta}$, 절대$\gamma$, 상대$\gamma$, 절대$F{\alpha}$, 상대$F{\alpha}$, 절대SMR, 상대SMR, $SMR/{\theta}$, $SMR+M{\beta}/{\theta}$, 절대$H{\beta}$, 상대$H{\beta}$, $H{\beta}/{\alpha}$, 절대$M{\beta}$, 상대$M{\beta}$, SEF50, ASEF50)와 진동이미지기술 10가지 지표(긴장/불안, 억제, 신경과민증, 밸런스, 매력, 자신감, 의심, 스트레스, 공격성, 에너지)를 상관 분석한 결과 뇌파(EEG)의 상대${\gamma}$파와 진동이미지기술의 신경과민증 지표가 (${\pm}$).414와 (${\pm}$).424로 높은 정적상관관계로 분석되었다.

  • Micrometeorological fluxes measured over a tall forest in a complex terrain are difficult to interpret. $CO_2$ storage often makes significant contributions to net ecosystem exchange of $CO_2$ (NEE) in early morning and during nighttime due to calm and stable conditions. We measured the above-canopy $CO_2$ flux along with its concentration profiles at eight levels within and above the canopy to evaluate $CO_2$ storage term. Our question is whether or not the $CO_2$ storage term can be estimated accurately from a single level measurement of $CO_2$ concentration in a complex terrain. Our objectives are (1) to document vertical profiles of $CO_2$ concentration and (2) to compare the diurnal and seasonal variations of $CO_2$ storages estimated from single and multi-level $CO_2$ concentration data. Seasonally averaged Diurnal variations of $CO_2$ concentration ranged from 398 to 455 ppm near the forest floor at 0.1 m whereas they ranged from 364 to 395 ppm at 40 m in the atmosphere. The diurnal variation of vertical profiles of $CO_2$ concentration shows very interesting features with season. At all eight levels, diurnal variation of $CO_2$ concentration showed little change in winter. In spring, the diurnal variations of $CO_2$ concentration at 8 levels showed three distinct groups of layers with height: the first layer: 0.1m (near surface), second layer: 1.0 m and 4.0m (below canopy) and the third layer: 7.4m to 40.7 m (near canopy and above). In summer, these three groups of layers were further separated with larger variations whereas such distinction became smaller in fall. The diurnal variation of $CO_2$ concentration in the first three layers near surface always showed higher concentration with larger variability. Typically, $CO_2$ concentration showed peaks in early morning and in the evening. After the evening peak, $CO_2$ concentration gradually increased except for those near the surface (i.e., 0.1, 1.0 and 4.0 m) where the concentrations actually decreased. We suspect that this could be attributed to the drainage flow of $CO_2$ along the hill slope from the headwater to downstream, which is not taken into account for net ecosystem $CO_2$ exchange. In comparison to the results of other studies, the distinct and different vertical structures of $CO_2$ concentrations observed at our site may be due to complex terrain and weak turbulent mixing under calm conditions at the site. The annual mean of diurnal variation of $CO_2$ storage flux from single level ranged from -0.6 to $0.9{\mu}mol\;m^{-2}s^{-1}$ and from multi-level from -1.2 to $1.0{\mu}\;{\mu}mol\;m^{-2}s^{-1}$. When compared against the results from the multi-level concentrations, the storage flux estimated from a single-level concentration was generally adequate except for specific hours near sunrise and sunset. Further details and their implication will be discussed in the presentation.

  • In light of addressing consumer health concern, coping with anti-tobacco movement, and promoting new product, tobacco industry is actively pursuing to make a new generation of cigarettes with low tar and nicotine deliveries, and less harmful substances. Low tar and low nicotine cigarettes increases their market shares dramatically world wide, especially in KT&G, multinational tobacco companies, EU countries, even in China regulated by CNTC to set up yearly target to lower tar and nicotine deliveries. On the other hand, to design a new cigarette with reduced harmful substances begins to gain speed. The "modified Hoffmann list" publishes thirty plus substances in tobacco leaf and main smoke stream, which is the prime suspect causing health problems. Various ways and means are developed to reduce such components including new tobacco breeds, new curing method, tobacco leaf treatment before processing, selected filtration system, innovated casing system to reduce free radicals, as well as some non conventional cigarette products. In TSRC held this year, the main topic is related to reduce tobacco specific nitrosamines in tobacco leaf. The new generation of cigarette is in the horizon. It still needs a lot help to produce commercial products with satisfied taste and aroma characters. The flavor industry is not regulated by many governments demanding which ingredients might or might not be for tobacco use. However, most of the cigarette companies self impose a list of ingredients to guide flavor suppliers to design flavors. Unfortunately, the number of ingredients in those lists is getting shorter every year. It is understandable that the health is not the only reason. Some cigarette companies are playing safe to protect the company from potential lawsuit, while others are just copying from their competitors. Moreover, it is obvious that it needs more assistance from casings and flavors to design new generation of cigarettes with missing certain flavor components in tobacco leaf and main smoke stream. These flavor components are either non-existed or at lower level at new form of cured tobacco leaf or filtered in the main smoke stream along with reduced harmful substances. The use of carbon filters and other selected filtration system poses another tough task for flavor system design. Specific flavor components are missing from the smoke analysis data, which brings a notion of "carbon taste" and "dryness" of mouth feel. It is ever more demanded by cigarette industry to flavor suppliers to produce flavors as body enhancer, tobacco notes, salivating agents, harshness reducer, and various of aromatic notes provided they are safe to use. Another trend is that water based flavor or flavor with reduced ethanol as solvent is gaining popularity. It is preferred by some cigarette companies that the flavor is compounded with all natural ingredients or all ingredients should he GMO free. The new generation of cigarettes demands many ways of new thinking process. It is also vital for tobacco industry. It reflects the real needs for the consumers that the cigarette product should be safe to use as well as bearing the taste and aroma characters smokers always enjoyed. An effective tobacco flavor system is definitely a part of the equation. The global trend of tobacco industry is like trends of any other industries lead by consumer needs, benefited with new technology availability, affected by the global economy, and subjected for various rules and regulations. Anti-tobacco organizations and media exceptionally scrutinize cigarette, as a legal commercial product. Cigarette is probably the most studied commercial product for its composition, structure, deliveries, effects, as well as its new developmental trend. Therefore, any new trend of cigarette development would be within these boundaries. This paper is trying to point out what it would be like for tobacco industry in the next few yews and what concerns the tobacco industry. It focuses mostly on the efforts to produce safer cigarettes. It is such a vital task for the tobacco industry and its affiliate industries such as cigarette papers, filters, flavors, and other materials. The facts and knowledge presented in this paper might be well known for the public. Some of the comments and predictions are very much personal opinion for a further discussion.

  • 저화소의 감시카메라와 같은 촬영 장비를 통해 사람의 얼굴을 인식할 경우, 화질이 낮아 얼굴을 포착하기 어렵다는 문제점이 있다. 이렇게, 사람의 얼굴을 인식하기 어렵다면 범죄용의자나 실종자를 특정해내지 못하는 등의 문제가 발생할 수 있다. 기존 이미지 속 안면 인식에 관한 연구들에서는 정제된 데이터셋을 사용하였기 때문에 다양한 환경에서의 성능을 가늠하기 어렵다는 한계가 존재한다. 이에, 본 논문에서는 저화질 이미지에서 안면 인식 성능이 떨어지는 문제를 해결하기 위해 다양한 환경을 고려한 저화질 안면 이미지에 대해 화질 개선을 수행하여 고화질 이미지를 생성한 뒤, 안면 특징점 검출의 성능 향상시키는 방법을 제안한다. 제안 방법의 현실 적용 가능성을 확인하기 위해 전체 이미지에서 사람이 상대적으로 작게 나타나는 데이터셋을 선정하여 실험을 수행하였다. 또한 마스크 착용 상황을 고려한 안면 이미지 데이터셋을 선정하여, 현실 문제로의 확장 가능성을 탐구하였다. 안면 이미지의 화질을 개선하여 특징점 검출 모델의 성능을 측정한 결과, 개선 후 안면의 검출 여부는 마스크를 착용하지 않은 이미지의 경우 평균 3.47배, 마스크를 착용한 경우 평균 9.92배로 성능 향상을 확인할 수 있었다. 안면 특징점에 대한 RMSE는 마스크를 착용한 이미지의 경우 평균 8.49배 감소, 마스크를 착용하지 않은 경우 평균 2.02배 감소한 것을 확인할 수 있었다. 이에, 화질 개선을 통해 저화질로 포착된 안면 이미지에 대한 인식률을 높여 제안 방법의 활용 가능성을 확인할 수 있었다.

  • 연구배경 : 재 감염 결핵의 경우 대부분이 폐 상부를 침범하므로 폐 하야에만 단독으로 결핵이 있는 경우에 폐 결핵보다는 폐렴, 폐암, 기관지 확장증, 폐농양등을 먼저 생각할 수 있어 이로 인해 진단이 늦어지거나 오진 되는 경우가 흔히 있다. 이에 저자들은 폐하야에만 결핵이 침범된 환자를 대상으로 그 임상 양상과 진단 방법을 후향적으로 분석하고자 하였다. 방 법 : 대상 환자는 1992년 1월부터 1994년 12월까지 한양대학교 의과대학 부속병원에 내원한 활동성 폐결핵 환자 724명중 폐 하야에만 결핵이 침범되어 있는 50명을 대상으로 하였다. 결 과 빈도 : 총 결핵 환자 724명중 폐 하야 결핵은 50예로 6.9%의 빈도를 보였다. 연령 및 성별 분포 : 남녀 비는 1 : 1.9로 여성에서 호발 하였다. 평균 연령은 43세 이었으며 고령 층에도 비교적 고른 분포를 나타내고 있었다. 임상 증상 : 기침이 34 (68%)로 가장 흔하였고 그외에 객담 26예(52%), 발열 19예(38%), 흉부 불쾌감 15예(30%)순으로 나타났다. 흉부 X-선 소견 : 우측에 더 호발 하는 양상을 보였고 침범 양상은 경변이 있는 경우가 26예(52%)로 가장 흔했고 고립종, 폐 허탈, 공통 형성 순으로 나타났다. 기관지 결핵 : 40%에서 나타났고 남녀 비는 1 : 3으로 여성에서 호발 하였으며 환자의 평균 연령은 44세였으며 고령층에서도 비교적 고른 분포를 보였다. 검사별 양성률 : 폐 하야 결핵 환자 총 50명중 단순객담 도말 검사 및 배양으로 25명이 진단되었고, 기관지 내시경 검사를 통해 9명이 추가로 진단되었으며 세침 흡입 조직 검사를 통해 16명이 추가 진단되었다. 기관지 내시경을 이용한 경우의 진단률(75.0%)이 단순 객담을 이용한 검사의 진단률(50.0%)보다 높은 양성률을 보였다. 동반 질환 : 당뇨병이 18%에서 동반되어 가장 많이 나타났으며 그 외에 빈혈, 류마티스 관절염과 신증후군으로 전신성 스테로이드를 사용한 경우, 신경성 식욕 불량증, 위암 등의 합병증이 있었다. 결 론 : 아직 결핵 환자가 많은 우리나라에서 폐하야에 병변이 있는 경우에 특히 당뇨병, 빈혈, 전신적 스테로이드를 사용하는 경우, 악성 종양 등 면역을 저하시키는 질환이 동반된 경우에는 결핵의 가능성을 항상 생각해야 하며 폐하야 결핵의 연령층이 젊은 연령에서 고령층으로 이동하고 있으므로 고령층에서도 이의 가능성에 유의하여야 할 것으로 생각된다. 또 폐하야 결핵에서 단순 객담을 이용한 항산균 도말 검사 및 배양 검사의 양성률이 낮으며 기관지 결핵의 동반률이 높으므로 기관지 내시경, 세침 흡입 조직 검사의 방법이 조기에 사용 되어야 하며 이를 통해 진단률을 높이는데 도움이 되리라 생각 된다.

  • Khori(高麗) refers to the Chaabog(reindeer) that live on lichens(蘚) on Mt. Soyon(鮮) in which pastures are the cold and dry plateau of North Eurasia. Thus, the origin region of the Khori or Koguryo that are the ancestors of the reindeer-herding pastoral nomads(馴鹿 遊牧民) can be said to be the Steppe-Taiga-Tundra pastoral areas of North Eurasia and North America. When the pastoral nomads moved on to the great mountain(大山) zone of the Jangbaek(長白) to the Baekdu(白頭) Mountains, they could have been in contact with pastoral farmers or agricultural farmers living there and they became the farmers remaining on agricultural farms. They were the Koryo people, the ancestors of Korea. Staying in one place, they gradually forgot the origin of their reindeer-herding pastoral nomadic history in the Northwest area of Mt. Soyon, the small mountain(小山) zone of the Steppe-Taiga-Tundra pastoral areas. In other words, they lost their identity as reindeer-herding pastoral nomads when they entered the agricultural area after leaving the pastoral area. However, since their basic genes had already formed when they lived on the cold and dry plateau of North Eurasia, it is possible to study their pastoral nomadic history focusing on 'the minority living in the broad area(廣域少數)', by utilizing highly advanced biotechnological science and focusing on genes and information technology innovation, and removing various past hindrances in research. Therefore, it is not so difficult to restore the reindeerherding pastoral nomadic history of the Koguryo(高句麗) people and secure their pastoral nomadic identity, of which the first steps have already been taken into their historical stages. The Eurasian continent and the Korean peninsula, especially the cold and dry plateau of North Eurasia and the Korean peninsula have been closely related to each other ecologically and historically. They can never be a separate space at all. The Eurasian continent lies horizontally east to west and thus, the continent forms an isothermal zone. Also, since the time of producing their own foods, it was relatively easy for people with their technology to move to other places owing to the pastoral nomadic characteristic of mobility. Unlike the Chungyen(中原) region, western Asia and the regions covering the Siberia-Manchu-Korean peninsula where food production revolution was first made were connected to the Mongolian lichens route(蘚苔之路: Ni, ukinii jam) and steppe roads. Although the ecological conditions of nature have changed a bit throughout a long history, it was natural for the many tribes in North Asia living on the largest Steppe-Taiga-Tundra area in the world to have believed 'the legends related to animals in relation to their founders and ancestors(獸祖傳說)'. Assuming that Siberian tigers and the tigers living on Mt. Baekdu were connected ecologically and genetically because of the ecological characteristics of the animals, and their migration from plateau to plateau, we would suspect that the Chosun(朝鮮) tribe living on Mt. Baekdu were ethnically and culturally more closely connected to the farther removed Ural-Altai tribes that lived on the cold and dry plateau region than to the Han(i14;) tribe who lived in Chungyen(中原) that was close to Mt. Baekdu. More evidence is the structure of the Korean language which has the form of 'Subject + Object + Verb', which is assumed to have originated from the speedy lifestyle of the reindeer-herding pastoral nomads. The structure is quite different from that of the Han(漢) language, which is based on agricultural life. Also, it is natural for reindeer riding reindeerherding pastoral nomads or horse-riding sheep-herding pastoral nomads(騎馬, 羊遊牧民) to have held military and political power over the region and eventually to have established an ancient pastoral nomadic empire in the process of their conquest of agricultural regions. The stages for founding global empires in the history of mankind maybe largely divided into two, in terms of ecological conditions and occupations. They are the steppes and the oceans. Of course, the steppe-based empires were established based on the skills to deal with horses and the ability to shoot arrows while riding horses, along with the use of iron ware in the 8th century BC. The steppe-based empires became the foundation for an oceanic empire, which could have been established by the use of warships and warship guns since the 15th Century. Based on those facts, we know that Chosun, Puyo(夫餘), and Koguryo are the products of a developmental process of pastoral nomadic empires on the steppes. Maybe we can easily find the pastoral nomadic identity of the Koguryo more than we expected when we trace the origins and history of the Korean tribe living in the pastures located in the northwest area of Mt. Jangbaek by focusing on pastoral nomadic mobility and organization just as we have investigated the historic origins of Anglo-Saxons in America by focusing on the times before the 15th Century. In the process, we should keep in mind that English culture originated from the Industrial Revolution and was directly delivered to the American continent, although America was far from England and was not an intermediate point on long sojourns either. Further, American culture came back to England in a more advanced form later. The most important thing currently to be resolved is to cause Koreans to look back on their own history in a freer way of thinking and with diverse, profound, and sharp insight, taking away the old and existing conventional recognition that is entangled with complicated interests with Korean people and other countries. The meanings of Chosun, Khori, and Solongos have been interpreted arbitrarily without any historic evidence by the scholars who followed conventional tradition of fixed-minded aristocrats in an agricultural society. If the Siberian cultural properties of the stone age, the earthenware age, the bronze age, and the iron age are analyzed in such a way, archaeological discovery will never be able to contribute to the restoration of the Koguryo's pastoral nomadic identity. One should transcend the errors that tend to interpret the cultural properties discovered in the pastoral nomadic regions as not being differentiated from those of agricultural regions and just interpret them altogether from the agricultural point of view. A more careful intention is required in the interpretation of cultural properties of ancient Korean empires that seem to have been formed due to mutual interactions of pastoral nomadic and agricultural cultures. Also, it is required that the conventional recognition chain of 'reverse-genes' be severed, which has placed more weight on agricultural properties than pastoral nomadic ones, since their settlement on agricultural farms was made after the establishment of their ancient pastoral nomadic empires. There is no reason at all to place priority on stoneware, earthenware, bronze ware, and iron ware than on wooden ware(木器) and other ware which were made of animal skins(皮器), bones and horns(骨角器), in analyzing the history in the regions of reindeer or sheep pastures. Reading ancient Korean history from the perspective of pastoral nomadic history, one feels strongly the instinctive emotions to return to the natural 'mother place'. The reindeer-herding pastoral nomadic identity of the Koguryo people that has been accumulated in volumes in their genes and hidden deep inside and have interacted organically could be reborn with Burqanism(Burqan refers to 不咸 in Chinese), which was their religion by birth and symbolized as the red willow(紅柳=不咸). The mother place of the Koguryo's people is the endless vast green pastures of North Eurasia and North America, where we anticipated the development of Korean livestock farming following the inherent properties in the genes of the reindeer-herding pastoral nomads with Korean ancestors. We anticipate that the place would be the core resource that could contribute to the development of life of living creatures following the inherent properties of their genes and biotechnological factors. In other words, biotechnology used for a search for clues on the well-being of humans could be the fruit brought by Burqanism of the Koguryo people and the fruit of the globalization of Korean livestock farming. It is the Chosun farmer in China come from the vast nomadic reindeer pastures of North Eurasia that resolved the food problem of a billion Chinese people with lowland paddy rice seeds (水稻) by transforming Heilongjiang Province(黑龍江省) into an oceanic lowland paddy rice field(水田). Even Mao Tse-tung(毛擇東) could not resolve the food problem by his revolution campaigns for tens of years. Today is the very time that requires the development of special livestock farming following the inherent properties of the ancient Korean reindeer-herding pastoral nomads that respected the dignity of life on the cold and dry plateau of North Eurasia and the America continent. I suggest that research should be started from the pastures of the Dariganga Steppe in East Mongolia that was the homeland of Hanwoo(韓牛) and the central horse-herding steppe place(牧馬場) of Chingis Khan's Mongolia. The Dariganga Steppe is awash with an affluent natural environment for pastoral nomadic living however, the quality of life of the pastoral nomads there is still low. I suggest we Koreans, the descendents of the Koguryo, should take our first steps for our livestock farming business project and develop the Northern nomadic pastures, here at the pastures of the Dariganga Steppe, which is the Mongolian core place of state-of-the-art technology for military weapons.
