  • 기술혁신의 물결은 크게 일본의 산업계로 불어닥치고 있으며, 종래와 같은 공학계만의 학과로서는 당할 길이 없을 만큼 기술영역의 기술업무가 주요부분을 점유할 것으로 예측된다. 기술이전을 원활화시키기 위해서는 기술이전의 각 단계에서 각각의 과학기술인재가 유효하게 활용되어야할 필요가 더욱 중요하게 된다. 산업기술의 이전에는 민간기술자의 유효한 활용이 불가결한 것이며, 민간기술용역이 중요시되고 있는 것이다. 선단기술의 개발은 일본에서는 석유파동이래 상품혁신시대로 접어들어 기존의 기술진행에 대한 작은 기술개선이 생산성향상과 직결되고 있는 점을 중요시해야 할 것이다. 필자는 기술사로서 경험한 기술개발의 사례에서 산업고고학의 필요성을 통감한 것이다. 지녹기술의 개발수법을 연구하고 그 사례를 들어 기술사로서의 역할을 말한바 있다. 더욱 일본정부가 실시하고 있는 공업기술이전연구소의 계획실적에 언급하고 나아가서는 한국에 대한 의견을 말하고 고도한 기술도입에 따른 체제와 기술사의 적임에 관해서 조언하고 싶다.

  • 이 연구는 일제강점기 군의 갯수를 317개에서 218개로 축소시키고 군의 명칭, 관할구역 및 경계, 그뿐 아니라 군청소재지와 군청사 건축에 큰 변화를 가져온 1914년 군폐합 과정에 주목한다. 연구의 목적은 군폐합 단행 과정에서 조선총독부와 각 도 사이에 오고간 문서를 통해 조선총독부가 취한 군청사 건축방침과 각 도 및 군의 대응, 행정절차, 1910년대 군청사의 건축상태와 업무환경은 어떠했는지를 파악하는 것이다. 이 연구는 문헌연구방법을 사용한다. 기본자료는 국가기록원이 소장하는 조선총독부 문서들 중 군폐합관계서류(국가기록원 정리번호 CJA002545; CJA002546; CJA002547; CJA002548; CJA002550)와 면폐합관계서류 2개 철(CJA002549; CJA002565) 안에 산재하는 군폐합 관련 서류들이다. 그밖에 1910년대 당시 발간된 신문인 매일신보와 기존 연구들도 주요한 자료로 사용한다. 화재나 군청소재지 이전 등 어쩔 수 없는 경우가 아니면 군청사의 신축에 매우 소극적이었고 신축을 위한 예산 배정에도 소극적이었던 조선총독부의 입장과 건축방침이 1910년대 군청사로 기존건물을 전용하거나 신축, 증개축, 개수 등 건축하는데 어떤 작용을 했는지와 당시 군청사의 건축상태 및 업무환경에 어떠한 영향을 미쳤는지 살펴본다. 이를 통해 건축적 특징에만 촛점을 맞춰왔던 기존의 연구시각과는 다른 각도에서 일제강점기 군청사 연구성과를 보완한다.

  • Introduction : Attention-deficit hyperactivity disorder (ADHD) was a newly coined term for a disease that existed prior to its naming in the mid 20th century. The issue about whether ADHD is a new disorder or merely a new name for an existing disorder is still controversial. The authors tried to find the clues to the answer for this question through reviewing historical documents for traces of ADHD. Contents : We could find literatures and medical records that contain possible ADHD symptoms. In particular, in 1845, Heinrich Hoffmann's 'fidgety Philip' or 'Johnny Look-in-the-air' nearly satisfies today's criteria for ADHD. Methylphenidate was approved as a promising chemical for inattention in 1957 before the establishment of the concept of ADHD. In 1968, ADHD was first officially introduced as "Hyperactivity Reaction of Childhood" by DSM-II. In 1980, DSM-III, 'Attention Deficit Disorder (ADD)' was adopted as an official diagnostic term and changed to 'ADHD' since the creation of DSM-III-R in 1987. Conclusion : As stated above, ADHD has existed since long ago and became familiar via an advanced diagnostic system and therapeutic options.

  • Background: Singapore has the stable healthcare system with utilizing pharmacist manpower in proper positions by demand of populations' health among Asian countries. Objective: This study aims to systematically review (1) the pharmacists' role and (2) the pharmacy education system of Singapore in comparison with Korea. Method: We searched for information about academic, medical and governmental institutions related to professional pharmacists' practice in Singapore by primarily using database such as DBpia, KISS, Google Scholar and ProQuest and the official website of the Singapore Ministry of Health. We contacted and arranged the visit schedules with National University of Singapore, National Health Group's polyclinics, Agency for Integrated Care, National University Hospital, and community chain pharmacies. During onsite visits, we interviewed pharmacists working in each institution and obtained additional documents and materials relevant to this manuscript work. Results: To become a registered pharmacist in Singapore, the pharmacy curriculum requires four full-time academic years and six additional months allotted for pre-registration training. Pharm.D. course is offered for pharmacy graduate students with additional two full-time years of study. Team teaching and inter professional education program seem the most significant method in pharmacy education. Pharmacists working at hospitals, polyclinics, and community pharmacies in Singapore take broader roles and offer more cognitive services such as smoking cessation program and medication reconciliation. Especially, pharmacists in Agency for Integrated Care fill the role of primary care providers for the continuing care of the community through the governmental support toward the patients-centered integrated care. Conclusion: Singaporean pharmacists take significant and active roles in collaboration with other healthcare providers. Efforts such as interprofessional pharmacy education and governmental endorsement of the systematic and interactive care between pharmacists and other medical providers in Singapore are needed to be urgently applied to Korea healthcare system for the promotion of population health.

  • The Gamrotenghwa of the Choson Dynasty is a unique genre of buddhist painting in that the destiny of the dead souls and the guidance to nirvana are expressed in reality. More than 50 of the Gamrotenghwa are known to be present, and the lower part of the paintings includes a wide assortment of folk customary scenes reflecting the social life style of the time when the painting was drawn, such as difficulties in life. public life, punishment and war. Changes in the costume of the people shown on the customary scenes of the Gamrotenghwa according to the time based changes in painting style were investigated in this study. The results are summarized in three points. First, the costumes of bureaucrats showed a tendency of preservation without any major changes in the painting. On the other hand, costumes of public and entertainer in the scenes were very close to those worn by the people at that time. The realistic description of public life in the painting may establish the value of the Gamrotenghwa as the historical documents. Second, the costume of the people in the painting showed a dual structure as the social positions; bureaucrats wore various official hats, large coats and belts to expose their social prestige. while the general public wore simple and convenient clothing which is divided into shirt and pants. The dual structure of the costume in the painting is in well accordance with that of the later period of Choson dynasty, suggesting that the customary scenes in the painting represent the social life style of the period. Finally, the customary scenes in the Gamrotenghwa are very variegated. which shows a variety of beauty of wearing even though they look coarse in a sense. The diversity of wearing beauty in the picture may contribute to the recreation of the beauty of shape in the new design of Hanbok.

  • Since the 17th century, the society of Joseon dynasty belongs to a period of rapid transition in many fields. As the building is a result to be produced on the basis of a society and economy, the general transition in a society is to be reflected into a process of building construction. Especially, a study on the material supply system of economic base in a process of building construction is one of vely important factors in an understanding or estimate of a building. On the premise, this paper is to examine the supply system of iron materials and the tools in the construction of the government managed buildings in the late of Joseon dynasty on a viewpoint of productivity. Construction reports and other documents in those days are examined for the study. Following conclusions have been reached through the study. 1) The general supply method of iron materials for a large-scale government construction was based on 'byulgong', that is, a kind of tribute. 2) Various methods were selected in the supply method of iron materials for government use in the late of Joseon dynasty. The priority order of choice in its government policy was put on an easiness of amount security, on a minimum of expenditure, and on an efficiency of construction execution. 3) The manufacturing technique of weaponry was used in the production method of iron materials and the tools for government use. The cooperation of the official, the army, and the merchant had improved the manufacturing technique of building construction.

  • The purpose of this study is to suggest a theoretical basis to name Sa(紗) and Ra(羅) remains properly by comparing and analyzing the name, usage, value, length and width of Sa(紗) and Ra(羅) recorded on documents made at the end period of Joseon. The features of Sa(紗) and Ra(羅) at the end of the Joseon Period are as follows. 1. The kinds of Sa(紗) are about 80, those of Ra(羅) are about 12, and those of Sa(紗) are significantly more than those of Ra(羅). In regard to the aspect of patterns, there were about 20 types of patterns in the case of Sa(紗), but no specific pattern for Ra(羅). 2. Some newly revealed patterns in the case of Sa (紗) are as follows. Baek -bok-mun(백복문) was a pattern full of ‘bats(박쥐[복])’, and Baek-jeop-mun(백접문) was a pattern full of ‘butterflies(나비[蝶])’ Jeop-mun(접문) was classified into ‘butterfly patterns(나비문[접문])’ and ‘traditional window flame patterns(창살문[접문])‘. 3. When considering the usages of Sa(紗) and Ra(羅), Sa(紗) was used for various detailed purposes according to their kinds and patterns, but Ra(羅) was mostly used for underwear. The most commonly used Sa(紗) was the Gab-sa type(甲紗類). On the contrary, the Go-sa type(庫紗類) was significantly less used than the Gab-sa type(甲紗類). However, it must have been of relatively high quality Sa(紗), shown by the fact that it was used for outer garments. In addition, the Gung-sa type(宮紗類) was the best quality Sa(紗), shown by the fact that it was used for court dress and official uniforms in the royal court. 4. Sa(紗) and Ra(羅) whose features have been examined we Gapsa(甲紗), Sun-in (純仁), Gosa(庫紗), Gwansa(官紗), Jusa(走紗), Eunjosa(은조사), Gwangsa(廣紗), Waesa(倭紗), Dorisa(도리사), Gong-yangsa(공양사), Rasa(羅紗), Danghangra(唐亢羅), Yanghangra(洋亢羅), Yunjura(윤주라), Eunra(銀羅), Jeohangra(저항라), Chura(秋羅). 5. Regarding the values of Sa(紗) and Ra(羅), they were high quality textures and its length and width of 1 Pil(疋), a roll of cloth, were not subdivided in detail such as in the case of plain weaved silks(平絹).

  • The importance of the standards and its related texts established by Codex Alimentarius Commission (CAC) had been increased by the Agreement of Application of Sanitary and Phytosanitary Measures (SPS Agreement) in World Trade Organization (WTO). To meet the needs of WTO SPS Agreement, biennial CAC meeting had been changed to every year. This study was conducted to analyze the effects on interval between CAC meetings. The years of adoption, revision and amendment of CAC texts were collected from the official standard list and individual texts from CAC homepage. The period since establishment of CAC was divided into four groups by starting negotiation of Uruguay Round, WTO foundation and reducing the interval between CAC meetings. The collected data were analyzed by SPSS program. The numbers of CAC standards, guidelines, recommendations, maximum residue levels, and miscellaneous texts were 202, 56, 46, 3 and 5, respectively. Since 8 documents didn't contain the adoption year, these texts were eliminated to analyze adoption year. For adoption, annually 11.26 texts were established since establishment of CAC and there were no significant difference among the 4 groups. However the average numbers of revisions and amendments of adopted texts for overall periods and for each period were 7.56, 0.93, 6.50, 17.20 and 19.75, respectively. The average numbers of overall decisions, defined as summation of adoption, revision and amendment of texts, for overall periods and for each period were 12.37, 6.27, 9.00, 17.40 and 29.25, respectively. There were significant differences by the WTO foundation and the interval between CAC meetings. The reduced interval of CAC meetings influenced to increase number of revisions and amendments of adopted texts, but not yet adoption of new text.
