자료관리와 정보력이 국력의 척도가 되었으나, 디지털 기술에의 의존 증대로 인한 위험마저 높아진 미묘한 상황을 맞고 있다. 그런 변화의 속도가 빠른 만큼 기존 자료의 디지털 전환 및 디지털 자료관리의 중요성도 급격히 증대되고 있다. 고고자료와 정보도 예외일 수는 없다. 과거에 산발적으로 이루어지던 디지털화를 좀 더 전면적이고 체계적으로 신속하게 수행하지 않을 수 없게 되었다. 그런 작업의 효과적인 진행을 위해서는, 디지털 아카이브에 포함될 고고자료의 특징에 대한 분명한 인식이 선행되어야 할 듯하다. 고고자료는 발굴이라는 원천을 파괴하는 과정을 통해 자료가 생성된다는 점, 장구한 시간대에 걸친 다방면의 인류 과거 경험을 연구 대상으로 하는바, 축적되는 자료의 종류가 다각적이고 그 양이 방대할 수밖에 없다는 점, 원본 수기자료(사진, 도면, 야장 등)의 자연적 소멸에 따른 피해가 심각하다는 점 등을 특징으로 한다. 이러한 특징은 디지털 암흑기를 맞을 경우, 원상 복구의 어려움이 상상을 초월할 정도로 커지게 할 수밖에 없다. 현재 경향과 자료의 특성을 동시에 고려해야만 지속가능한 고고 디지털 아카이브의 구축의 전략이 수립될 것이다. 필자는 소비자인 인문학도의 입장에서 ① 디지털 관리책무 체제 확충, ② 활용성에 대한 인식과 역량의 제고, ③ (국제) 공조적 체계의 구축, ④ 디지털고고학 플랫폼으로의 도약 등을 그 전략으로 제안한다.

오랜 세월 동안 감정은 이성과 합리성에 방해가 될 뿐만 아니라 위험한 것으로까지 간주되었다. 인간의 행동을 다루는 드라마 장르의 역사 속에서 보더라도 감정은 작품 속에서 인물을 추동하는 중요한 힘으로 그려지면서도 결국은 파국을 초래하는 오류 또는 결함으로 묘사되는 경우가 많았다. 오늘날 인지 과학 분야의 성과를 토대로 감정이 인간의 사고, 판단 및 행동에 얼마나 중요한지와 이성과 감정이 얼마나 밀접하게 결합 되어 있는지가 밝혀지고 있다. 본 연구는 감정의 사회성을 바탕으로 드라마 장르에서 다루어지는 감정을 연구한다. 감정은 개인만의 문제가 아니라 사회적 성격을 드러낸다. 영화 <생일>은 개인의 감정에 대한 의미 구성과 행동 명령이 스스로에게 고통의 굴레가 되는 동시에 사회적으로 영향을 끼칠 수 있음을 보여준다. 그리고 사회적 관계 가운데 그 문제를 풀어내는 방안을 보여준다. 또한 드라마 속에 등장하는 감정의 교류 양상과 행위들은 관객들에게도 영향을 끼친다. 개인의 성향과 선입관에 따라 다른 반응이 있을 수도 있지만 기본적으로 거울뉴런의 활동은 감정의 집단지향성을 가능케 하고 공감의 가능성을 만들어내는 매커니즘을 작동하게 된다. 본 연구가 드라마콘텐츠 분야에서 감정에 대한 이해도를 높이고 이를 유용하게 활용할 수 있도록 하는데 유의미한 암시와 자극이 되길 바란다.

이 글은 조선왕조 제4대 군주 세종대왕의 정신세계를 고찰하는 일환으로 그에게서는 유교와 불교가 동시에 중시되었다는 점을 밝혀 보려는 것이다. 왕조실록에서는 세종이 '해동의 요순(堯舜)'으로 평가되지만, 자세히 살펴보면 부처를 숭신했던 사례들을 종종 발견할 수 있다. 특히 왕실에서 생명의 위험성이 다가오면 구병(救病)을 위한 기도행사를 펼쳤으며 선왕의 사당에는 불당까지 겸비할 것을 추구하였다. 이러한 이면에는 세종의 유불화해의식이 작용하고 있었던 것이다. 유신(儒臣)들은 숭유억불의 기조를 따라 유교문화 확장의 차원에서 부단히 척불론을 전개했다. 특히 왕실의 불사(佛事)에 대해서는 군주와 격렬한 논쟁을 벌이기도 했다. 그러나 세종은 불교의 역사성과 현재성, 그리고 자신의 종교체험 등에 유의하여 그 적폐를 제거하면서도 불교 자체의 존재가치를 긍정하였다. 그렇다고 유교사상을 내세워 불교를 비난하거나 불교정신을 따라 유교를 경시하는 것도 아니었다. 즉 그는 유교를 높이면서도 불교를 버릴 수 없는 것으로 보고, 또 불교를 긍정하면서도 유교적인 삶의 태도를 중시했다. 현실적 삶의 태도로서는 유교윤리를 추구하고 생사 초월의 신앙적 측면으로는 불교를 높이며 융화해가는 입장을 보인 것이다. 특히 생사문제 등 인간으로서의 한계의식이 깊어질 때는 유교의 천명사상이나 제사의례뿐만 아니라 부처에의 믿음으로 위안을 찾을 수 있다고 보았다. 세종에서 유불화해의식의 절정은 선왕을 모시는 사당 문소전에 반드시 불당이 함께 있어야 한다는 모습으로 나타났다. 그와 같은 화해의식이 작용하게 되는 원인으로는 첫째 유교와 불교는 모두 왕조국가의 기조를 튼튼히 하는 데에 긴요하다고 인식되었다는 점, 둘째 기도에 대한 감응을 얻으며 안심입명의 안정감을 가지게 되었다는 점, 셋째 인간 평등의 가치관이 중시되고 있었다는 점 등을 말할 수 있다. 그리고 세종 유불화해의식이 가지는 의의로서는 ① 사람들의 정신적 상황 그대로를 긍정하여 평화적 삶의 기반을 제고시킬 수 있다는 것, ② 도덕적인 삶과 종교적인 삶의 포괄성을 높일 수 있다는 것, ③ 여러 가지 사회적 대립형상을 예방하는 데에 기여한다는 점 등을 들 수 있다.

Background and Objectives: O-cyclic phytosphingosine-1-phosphate (cP1P) is a synthetic chemical and has a structure like sphingosine-1-phosphate (S1P). S1P is known to promote cell migration, invasion, proliferation, and anti-apoptosis through hippocampal signals. However, S1P mediated cellular-, molecular mechanism is still remained in the lung. Acute lung injury (ALI) and its severe form acute respiratory distress syndrome (ARDS) are characterized by excessive immune response, increased vascular permeability, alveolar-peritoneal barrier collapse, and edema. In this study, we determined whether cP1P primed human dermal derived mesenchymal stem cells (hdMSCs) ameliorate lung injury and its therapeutic pathway in ALI mice. Methods and Results: cP1P treatment significantly stimulated MSC migration and invasion ability. In cytokine array, secretion of vascular-related factors was increased in cP1P primed hdMSCs (hdMSC^cP1P), and cP1P treatment induced inhibition of Lats while increased phosphorylation of Yap. We next determined whether hdMSC^cP1P reduce inflammatory response in LPS exposed mice. hdMSC^cP1P further decreased infiltration of macrophage and neutrophil, and release of TNF-α, IL-1β, and IL-6 were reduced rather than naïve hdMSC treatment. In addition, phosphorylation of STAT1 and expression of iNOS were significantly decreased in the lungs of MSC^cP1P treated mice. Conclusions: Taken together, these data suggest that cP1P treatment enhances hdMSC migration in regulation of Hippo signaling and MSC^cP1P provide a therapeutic potential for ALI/ARDS treatment.

Technetium-99 (⁹⁹Tc) is recognized as a critical concern in the disposal of spent nuclear fuel due to its long half-life and remarkable stability, existing predominantly as TcO₄^- in the natural environment. The anionic form of technetium is highly soluble and mobile, posing significant environmental risks from the viewpoint of nuclear waste management. Thus, developing efficient and cost-effective sorbents for aqueous Tc(VII) is essential for mitigating relevant contamination. In the present work, the adsorption characteristics of Re(VII), a chemical analog of Tc(VII), were investigated using the clay mineral bentonite, modified with two different organic cations: hexadecylpyridinium (HDPy) and hexadecyltrimethylammonium (HDTMA). Sorption experiments were conducted at a liquid-to-solid ratio of 1 g/L with Re(VII) solutions prepared at concentrations from 10^-4 mol/L to 10^-6 mol/L. The sorption ratio and distribution coefficients were determined with samples collected at reaction times of 10, 50, 100, and 500 minutes after 0.45 ㎛ syringe filtration. In parallel, the modified bentonite samples were further analyzed using the X-ray diffraction (XRD) method to understand the adsorption mechanism of Re(VII) onto the target minerals. According to the quantification analysis results, a rapid equilibrium reaction of aqueous Re(VII) for all modified bentonite samples was identified. Moreover, near-complete adsorption of Re(VII) was observed when the bentonite was modified at 200-400% of its cation exchange capacity (CEC) for both organic cations. For cases of lower modification, the HDTMA-modified bentonite showed relatively higher adsorption efficiency compared with the one modified with HDPy. This result was inferred to be due to the difference in inter-layer spacing based on the characteristics of the organic cations. It is expected that the results obtained through this study will serve as a preliminary case for the synthesis of adsorbents for the retardation of highly mobile anionic radionuclides, such as I and Tc, in the natural environment.

A costume reveals the social characteristics of the era in which it is worn, thus we can say that the history of change of the costume is the history of change of the living culture of the era. Since the Three States era, the costume structure of this country had been affected by the costume system of the China's historical dynasties in the form of the grant therefrom because of geographical conditions, which affection was conspicuous for the bureaucrat class, particularly including but not limited to the Kings' familities. Such a grant of the costume for the bureaucrat class (i.e., official uniform) was first given by the Dang-dynasty at the age of Queen Jinduck, the 28th of the Shilla-dynasty. Since then, the costume for the bureaucrats had consecutively been affected as the ages had gone from the unified Shilla, to the Koryo and to the Yi-dynasty. As the full costumes officially used by government officials (generally called "Baek Gwan") in the Yidynasty, there existed Jo-bok, Gong-bok and Sang-bok. Of such official costumes, Gong-bok was worn at the time of conducting official affairs of the dynasty, making a respectful visit for the expression of thanks or meeting diplomatic missions of foreign countries. It appears no study was made yet with regard to the Gong-bok while the studies on the Jo-bok and the Sangbok were made. Therefore, this article is, by rendering a study and research on the styles of costumes of civil servants' stone images erected at the Kings' tombs of the Yi-dynasty, to help the persons concerned understand the Gong-bok, one of the official costume for Baek Kwan of that age and further purports to specifically identify the styles and changes of the Gong-bok, worn by Baek Gwan during the Yi-dynasty, consisting of the Bok-doo (a hat, four angled and two storied with flat top), Po (gown), Dae (belt), and Hol (small and thin plate which was officially held by the government officials in hand, showing the courtesy to and writing brief memorandums before the King) and Hwa (shoes). For that purpose, I investigated by actually visiting the tombs of the Kings of the Yi-dynasty including the Geonwon-neung, the tomb of the first King Tae-jo and the You-neung, the tomb of the 27th King Soon-jong as well as the tombs of the lawful wives and concubines of various Kings, totalling 29 tombs and made reference to relevant books and records. Pursuant. to this study, of the 29 Kings' tombs the costume styles of civil servants' stone images erected at the 26 Kings' tombs are those of Gong-bok for Baek-gwan of the Yi-dynasty wearing Bok-doo as a hat and Ban-ryeong or Dan-ryenog Po as a gown with Dae, holding Hol in hand and wearing shoes. Other than those of the 26 tombs, the costume styles of the Ryu-neung, the tomb of the Moon-jo who was the first son of 23rd King Soon-jo and given the King's title after he died and of the You-neung, the tomb of the 27th King Soon-jong are those of Jobok with Yang-gwan (a sort of hat having stripes erected, which is different from the Bok-doo), and that of the Hong-neung, the tomb of the 26th King Go-jong shows an exceptional one wearing Yang-gwan and Ban-ryeong Po ; these costume styles other than Gongbok remain as the subject for further study. Gong-bok which is the costume style of civil servants' stone images of most of the Kings' tombs had not been changed in its basic structure for about 500 years of the Yi-dynasty and Koryo categorized by the class of officials pursuant to the color of Po and materials of Dae and Hol. Summary of this costume style follows: (1) Gwan-mo (hat). The Gwan-mo style of civil servants' stone images of the 26 Kings' tombs, other than Ryu-neung, Hong-neung and You-neung which have Yang-gwan, out of the 29 Kings' tombs of the Yi-dynasty reveals the Bok-doo with four angled top, having fore-part and back-part divided. Back part of the Bok-doo is double the fore-part in height. The expression of the Gak (wings of the Bokdoo) varies: the Gyo-gak Bok-doo in that the Gaks, roundly arisen to the direction of the top, are clossed each other (tombs of the Kings Tae-jong), the downward style Jeon-gak Bok-doo in that soft Gaks are hanged on the shoulders (tombs of the Kings Joong-jong and Seong-jong) and another types of Jeon-gak Bok-doo having Gaks which arearisen steeply or roundly to the direction of top and the end of which are treated in a rounded or straight line form. At the lower edge one protrusive line distinctly reveals. Exceptionally, there reveals 11 Yang-gwan (gwan having 11 stripes erected) at the Ryu-neung of the King Moon-jo, 9 Yang-gwan at the Hong-neung of the King Go-jong and 11 Yang-gwan at the You-neung of the King Soon-jong; noting that the Yang-gwan of Baek Kwan, granted by the Myeong-dynasty of the China during the Yi-dynasty, was in the shape of 5 Yang-gwan for the first Poom (class) based on the principle of "Yideung Chaegang" (gradual degrading for secondary level), the above-mentioned Yang-gwans are very contrary to the principle and I do not touch such issue in this study, leaving for further study. (2) Po (gown). (a) Git (collar). Collar style of Po was the Ban-ryeong (round collar) having small neck-line in the early stage and was changed to the Dan-ryeong (round collar having deep neck-line) in the middle of the: dynasty. In the Dan-ryeong style of the middle era (shown at the tomb of the King Young-jo); a, thin line such as bias is shown around the internal side edge and the width of collar became wide a little. It is particularly noted that the Ryu-neung established in the middle stage and the You-neung in the later stage show civil servants in Jo-bok with the the Jikryeong (straight collar) Po and in case of the Hong-neung, the Hong-neung, the tomb of the King Go-jong, civil servants, although they wear Yang-gwan, are in the Ban-ryeong Po with Hoo-soo (back embroidery) and Dae and wear shoes as used in the Jo-bok style. As I could not make clear the theoretical basis of why the civil servants' costume styles revealed, at these tombs of the Kings are different from those of other tombs, I left this issue for further study. It is also noted that all the civil servants' stone images show the shape of triangled collar which is revealed over the Godae-git of Po. This triangled collar, I believe, would be the collar of the Cheomri which was worn in the middle of the Po and the underwear, (b) Sleeve. The sleeve was in the Gwan-soo (wide sleeve) style. having the width of over 100 centimeter from the early stage to the later stage arid in the Doo-ri sleeve style having the edge slightly rounded and we can recognize that it was the long sleeve in view of block fold shaped protrusive line, expressed on the arms. At the age of the King Young-jo, the sleeve-end became slightly narrow and as a result, the lower line of the sleeve were shaped curved. We can see another shape of narrow sleeve inside the wide sleeve-end, which should be the sleeve of the Cheom-ri worn under the Gong-bok. (c) Moo. The Moo revealed on the Po of civil servants' stone images at the age of the King Sook-jong' coming to the middle era. Initially the top of the Moo was expressed flat but the Moo was gradually changed to the triangled shape with the acute top. In certain cases, top or lower part of the Moo are not reveald because of wear and tear. (d) Yeomim. Yeomim (folding) of the Po was first expressed on civil servants' stone images of the Won-neung, the tomb of the King Young-jo and we can seemore delicate expression of the Yeomim and Goreum (stripe folding and fixing the lapel of the Po) at the tomb of the Jeongseong-wanghoo, the wife of the King Young-jo, At the age of the King Soon-jo, we can see the shape of Goreum similar to a string rather than the Goreum and the upper part of the Goreum which fixes Yeomim was expressed on the right sleeve. (3) Dae. Dae fixed on the Po was placed half of the length of Po from the shoulders in the early stage. Thereafter, at the age of the King Hyeon-jong it was shown on the slightly upper part. placed around one third of the length of Po. With regard to the design of Dae, all the civil servants' stone images of the Kings' tombs other than those of the Geonwon-neung of the King Tae-jo show single or double protrusive line expressed at the edge of Dae and in the middle of such lines, cloud pattern, dangcho (a grass) pattern, chrysanthemum pattern or other various types of flowery patterns were designed. Remaining portion of the waist Dae was hanged up on the back, which was initially expressed as directed from the left to the right but thereafter expressed. without orderly fashion,. to the direction of the left from the right and vice versa, Dae was in the shape of Yaja Dae. In this regard, an issue of when or where such a disorderly fashion of the direction of the remaining portion of waist Dae was originated is also presented to be clarified. In case of the Ryuneung, Hong-neung and You-neung which have civil servants' stone images wearing exceptional costume (Jo-bok), waist Dae of the Ryu-neung and Hong-neung are designed in the mixture of dual cranes pattern, cosecutive beaded pattern and chrvsenthemum pattern and that of You-neung is designed in cloud pattern. (4) Hol. Although materials of the Hol held in hand of civil servants' stone images are not identifiable, those should be the ivory Hol as all the Baek Gwan's erected as stone images should be high class officials. In the styles, no significant changes were found, however the Hol's expressed on civil servants' stone images of the Yi-dynasty were shaped in round top and angled bottom or round top and bottom. Parcicularly, at the age of the King Young-jo the Hol was expressed in the peculiar type with four angles all cut off. (5) Hwa (shoes). As the shoes expressed on civil servants' stone images are covered with the lower edges of the Po, the styles thereof are not exactly identifiable. However, reading the statement "black leather shoes for the first class (1 Poom) to ninth class (9 Poom)," recorded in the Gyeongkook Daejon, we can believe that the shoes were worn. As the age went on, the front tips of the shoes were soared and particularly, at the Hong-neung of the King Go-jong the shoes were obviously expressed with modern sense as the country were civilized.

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.

Thirty three members of the Korean Association of Pediatric Surgeons were surveyed to determine the clinical manifestations and current management of infantile hypertrophic pyloric stenosis (IHPS). The members completed a registration form and a questionnaire that indicated their treatment preferences for patients treated during 1996. The response rate was 84.8 %, and 23 institutions participated. Three hundred and sixty-three cases of IHPS were analysed. The male to female ratio was 5.15: 1. The presenting symptoms were nonbilious vomiting in 363 cases(100 %), palpable mass in the upper abdomen in 200 cases (55.1 %) and visible peristaltic waves in 67 cases(18.5 %). Fluid therapy was done in 161 cases(44.4 %) for preoperative preparation. Twenty patients(5.5 %) were premature. There were 27 low birth weight babies(7.7 %). The onset of symptoms ranged from 1 to 14 weeks of age with a peak occurrence at 2 to 4 weeks of age. Two hundred and thirty-six cases(66.6 %) presented within 4 weeks of age. There was one set of male twins and a family history of twins. The modes of feedings were: breast feeding; 69 cases(24.5 %), formula feeding; 176 cases(62.4 %) and mixed feeding; 37 cases(13.1 %). The preferred diagnostic modalities were ultrasonography (US) 229 cases(63.1 %), UGI series 27 cases(7.4%) and US and UGI series combined 86 cases(23.7 %). Only 21 cases(5.8 %) were operated on without imaging study, ie. with positive physical finding. Perforation of the mucosa during pyloromytomy occurred in 5 cases. All were treated successfully with primary closure. Persistent vomiting over 2 weeks after operation were reported in 5 cases. Three wound infections, one aspiration pneumonia and one postoperative bleeding were reported. There was no mortality in 363 cases.

치열궁내의 공간 부조화를 단순히 가용 arch perimeter에 대한 tooth material의 총합의 차이만으로 예측하는 것은 치아의 이동을 단지 평면적으로만 해석한 것인 반면, 실제로 치아는 치료에 의해 3차원적으로 움직이게 되어 치열궁 형태와 curve of Spee의 정도 그리고 치축 각도와 경사에도 영향을 받게 된다. 본 연구는 교정환자의 치료전 모형분석시 치열궁내 공간 부조화를 보다 분석적으로 평가하기 위해 소구치 발치 후 arch perimeter의 감소와 전치부의 전후방적인 이동량간의 관계를 알아보고 아울러 curve of Spee와 기저골내 기준평면에 대한 전치부의 치축 각도 그리고 전치부 총생등이 어떤 영향을 미치는 지에 대해 고찰해 보고자 한다. 연세대학교 치과대학병원 교정과에 내원하여 교정치료를 받은 환자 중 Angle씨 제 I급 부정교합이며 4개의 제 1소구치를 발거한 양악 전돌자로서 치아에 형태학적 변이 및 보철물을 갖지 않은 자, 치아수에 이상이 없는 자, 교모나 이소맹출치를 갖지 않은 자, 견치 및 대구치가 Angle씨 제 I급 교합관계를 가지며 3m이상의 치아밀집을 갖지 않은 자를 대상으로 하여 치아모형 분석 결과 다음과 같은 결론을 얻었다. 1. 견치간 폭경이 유지될 경우, 제 1소구치 발거 후 하악 중절치가 후방이동 될 수 있는 공간의 양은 소구치 발거 공간의 크기보다 크게 나타났으며, 그 차이는 1mm보다 작았다. 이때 치열궁의 형태가 전방으로 좁아질수록 그 차이가 증가하였다. 2. 견치간 폭경이 구치부의 폭경에 일치되게 확장될 경우 견치간 폭경이 유지될 때보다 3mm내외의 중절치의 후방이 동이 가능한 것으로 나타났다. 3. 중절치의 후방이동시 치체이동과 경사이동에서 가능한 절연의 전후방적인 차이가 미세하게 나타났다. 4. 견치간 폭경을 유지하면서 전치부 분절내 총생을 해소할 경우, 처음의 전치부 분절의 장경이 클수록 중절치의 전방 이동량이 증가하였다. 5. Curve of Spee를 leveling할 경우, arch perimeter의 증가량은 Curve of Spee의 최대 길이의 1/2보다 적게 나타났다.
