The process of manufacturing enterprise takes the potential injury agents (moving equipment, machines and tools, hazards, etc). The industrial accidents due to these occasion happen unexpectedly. Safety management, in the manufacturing enterprise, are a moral action for worker, and improve the production efficiency and decrease the accident cost. In this study, industrial accidents are analyzed on the actual condition for 339 manufacturing enterprise, and select the 9 sampling enterprise. We simulate the relationship between accident cost and safety management cost. So, We suggest the safety management counterplan. The actual condition of the industrial accidents were analyzed by I.L.O. statistical analysis equations, which are expressed by (1) and (2). FR=N/H×10^6 …(1) SR=S/H×10³ …(2) Logical development of the alternatives for safety management counterplan based on the structure of industrial accident. We derived characteritics of the industrial accidents, and suggested a few counterplan of industrial accidents for manafacturing enterprises in Jin-Ju area.

최진현,김용배,안성자,이형식,박원,신경환,Su Ssan Kim,김진희,이규찬,김동원,서현석,신현수,서창옥 한국유방암학회 2016 Journal of breast cancer Vol.19 No.3

Purpose: The aim of this study is to present the incidence of radiation pneumonitis (RP) reported within 6 months after treatment for breast cancer with or without internal mammary node irradiation (IMNI). Methods: In the Korean Radiation Oncology Group (KROG) 08-06 phase III randomized trial, patients who were node-positive after surgery were randomly assigned to receive radiotherapy either with or without IMNI. A total of 747 patients were enrolled, and three-dimensional treatment planning with computed tomography simulation was performed for all patients. Of the 747 patients, 722 underwent chest X-rays before and within 6 months after radiotherapy. These 722 patients underwent evaluation, and RP was diagnosed on the basis of chest radiography findings and clinical symptoms. The relationship between the incidence of RP and clinical/dosimetric parameters was analyzed. Results: RP developed in 35 patients (4.8%), including grade 1 RP in 26 patients (3.6%), grade 2 RP in nine patients (1.2%); there was no incidence of grade 3 or higher RP. Grade 2 RP cases were observed in only the IMNI group. The risk of developing RP was influenced by IMNI treatment; pneumonitis occurred in 6.5% of patients (n=23/356) who underwent IMNI and in 3.3% of patients (n=12/366) who did not (p=0.047). The differences in lung dosimetric parameters (mean lung dose, V10–40) were statistically significant between the two groups. Conclusion: IMNI treatment resulted in increased radiation exposure to the lung and a higher rate of RP, but the incidence and severity of RP was minimal and acceptable. This minor impact on morbidity should be balanced with the impact on survival outcome in future analyses.

실험의 의미 재고를 통한 현상중심의 실험교육의 필요성 제안 -이언 해킹(Ian Hacking)의 현상의 창조를 중심으로-

최진현,전상학 한국과학교육학회 2024 한국과학교육학회지 Vol.44 No.1

본 연구에서는 이언 해킹(Ian Hacking)의 실험 철학에 대한 철학적관점을 탐구하고 이 관점이 학교 실험 교육에 미칠 영향에 대한 논의하였다. 그간 다수의 철학자들은 실험이 이론을 검증할 때에만 중요하다는 이론 선행적인 관점을 주장하였다. 이와 마찬가지로 학교 교육에서도 실험의 주요 목적은 이론의 확인과 입증에 초점을 맞춘 관점이 주류를 이룬 것으로 보인다. 그러나 이러한 이론 선행적인 관점과는 대조적으로 해킹을 포함한 실험 철학자들은 실험 자체가 자율성과 생명력을 갖는다는 주장을 제안하였다. 해킹은 개입하기와 조작하기를 통해 실험의 이론 자율적인 성격을 강조하면서 실험에서 그동안상대적으로 간과되었던 도구 사용, 재료, 과학자의 솜씨와 같은 요소들의 중요성을 강조하였고, 과학 활동에서의 실험의 역할과 그의 중요성을 재고하였다. 본 연구에서는 이러한 철학적 입장이 학교 실험교육에도 적용할 수 있는 것으로 보았으며, 본 연구에서 제시하는현상중심의 관점을 통해 도구 사용, 실험자의 개입, 모델링 활동과같은 과학적 실천을 가르치는 데 도움이 될 것으로 예상한다. In this study, we explored the philosophical perspective of Ian Hacking on experimentation and discussed its potential impact on science education in schools. Traditionally, many philosophers have advocated a theory-driven view of experimentation, emphasizing its importance primarily in validating theories. Similarly, in the context of education, the prevailing perspective has been to focus on experimentation primarily as a means of confirming and proving theories. However, in contrast to this theory-driven perspective, philosophers like Hacking have proposed that experimentation itself possesses autonomy and vitality. Through their discussions, they have brought to light the significance of previously overlooked elements in experiments, such as tool usage, materials, and the involvement of scientists. They have prompted a reevaluation of the role and importance of experiments in scientific activities. Therefore, in this study, we consider the application of this philosophical standpoint to school experimental education. We anticipate that the phenomenon-centered perspective we propose in this research will be beneficial for teaching scientific practices, including tool usage, the involvement of experimenters, and modeling activities.

A series of field studies were conducted to examine the reality of tea production, marketing channel, profitability, administrative support and environment. From these. results, the alternatives for the efficient management of Korean tea industry are suggested. The following problems are found in the undergrowth of the Korean tea industry. 1) Small size of plantation. 2) Demand shortage of tea. 3) No specialized research institute or promotion agency. 4) Complexity and small scale of marketing channel. 5) High price of tea set and difficulty of the tea ceremony. In order to assure the profitability of tea-cultivator, the suggestions can be made as below. 1) Increase of the tea demand. 2) Enlargement of the plantation size. 3) Readjustment of the marketing channel. 4) Expansion of the administrative supports. 5) Consideration of the culture environments. The above suggestions can be specified as in the following. 1) Demand expansion: ① Establish a cultivator cooperation association for joint-cultivating, -manufacturing and -selling of tea. ② Offer the public relations, guidelines and education programs at the level of government agency or education board. ③ Develop the various kinds of tea products besides a tea bag. ④ Upgrade the brand or quality of teas such as Oryong-tea or pojong-tea. 2) Enlargement of the tea plantation. 3) Establishment of a specialized research institute. ① Development or import of the productive tea-seedlings. ② Improvement of culture methods. 4) Re adjustment of the tea markating channel-it can be suggested as follows: ※그림※ 5) Expansion of administrative supports. ① Tax exemption for the tea cultivator, the tea manufacturer and the tea seller. ② Drinking of green tea in substitution for coffee at the public offices. ③ Relaxation of restrictions on forest preservation area or green belt for tea plantation. ④ Government multidimensional supports for small farmers. ⑤ Assurance of the accurate statistical figures. As one of the most important factors for the tea plantations is the growth environments, it is critical to choose the proper area of plantation. For the future references, the realities of climates and environments for cultivation are summarized. 1) The number of collective cultivating districts of Korean tea plants are; 65 districts in Jeon-nam (1,706. 8749ha), 15 districts in Jeon-buk (201. 135㏊), 11 districts in Keong-nam (46. 405㏊), 1 districts in Keong-buk (2. 66㏊), 2 districts in Pusan (1. 32㏊), 2 districts in Jeju (140㏊)-the total is 96 districts (2,098. 3449㏊). 2) The districts ranges from 120°10 to 129°20 longitude and from 33°30 to 35°30 in the north latitude, and the most nothern and southern districts of them are Iksan in Jeon-buk and Seoguipo in Jeju respectively. 3) The monthly average temperature of those dictricts range from 12.3℃ (in Iksan) to 15.5℃ (in Seoguipo). The monthly average humidity range from 67% (in Ulsan, Dongrae) to 78% (in Haenam). The monthly average rainfall range from 1,000㎜(in Wolseong) to 1,400㎜ (in Seoguipo). 4) The cold indices of the districts range from -20.9℃ (Jeonju) to -0.2℃ (Seoguipo). The soil components are mainly gneiss and granite (in districts of Jeon-nam and Jeon-buk). And the PH of the soil ranges 3 to 5. 5) The altitude of the districts ranges from 20m (Hadong, Hwague) to 600m (Mt. Mudeung). The gradient of the districts ranges from 25° to 30°. The environmental plants of them are composed of bamboes, needle-leaf trees and broad-leaf trees.

추간판 내 수핵 대체용 주사형 Poly(2-hydroxyethyl Methacrylate)계 하이드로젤

최진현 한국생체재료학회 2007 생체재료학회지 Vol.11 No.2

Poly(2-hydroxyethyl methacrylate-co-sodium methacrylate) (poly(HEMA-co-SMA)) hydrogel was synthesized in order to replace nucleus pulposus in a degenerated intervertebral disc without surgical excision and implantation of prosthesis. The aqueous mixture of HEMA, SMA, EGDMA, and redox initiators was gelled at 36.5oC within 10-15 minutes. The water content and compressive modulus of this hydrogel were higher than those of a natural nucleus pulposus. Poly(HEMA-co-SMA) injectable hydrogel was inserted successfully into a rabbit's degenerated disc. After 1 month, it was revealed that dehydration and fibrosis were prevented dramatically in a hydrogel-injected disc compared with a degenerated disc. From histology, fusion of macrophages or formation of foreign-body giant cells were not detected in a hydrogel-injected nucleus pulposus. Hence, poly(HEMA-co-SMA) injectable hydrogel is suggested as a feasible prosthesis which has physical properties and biostabilities enough to replace nucleus pulposus in a degenerated disc.

과학자의 ‘손탄다’ 현상이 과학교육에 주는 함의 -이언 해킹의 현상의 창조를 중심으로-

The purpose of this study is to examine the practice of scientists from the perspective of Ian Hacking’s ‘creation of phenomena’. Scientific phenomena, according to Hacking, are regular and do not exist in nature without the intervention of scientists or experimental tools. This study tries to derive scientific educational meaning by analyzing the thoughts and episodes of the ‘Sontanda (inter-individual variability)’ phenomenon experienced by four life scientists. The Sontanda phenomenon is a common term used by scientists to describe phenomena in which findings do not appear consistently even when studies are carried out using the same experimental procedure and materials. The following four educational implications were discovered as a result of the research. First, we confirmed the importance of embodied knowledge, or non-verbal knowledge, which solves issues by making appropriate judgments and reactions at all times, rather than simply becoming accustomed to the experimental method. This argues that propositional knowledge and non-verbal knowledge should be handled equally in order to provide students with a practical scientific inquiry. Second, we tried to reconsider the picture of the experiment. The phenomenon revealed in the interviews of scientists is rare, and it takes a long time to stabilize the phenomenon. On the other hand, the image of school experiments is always positive and consistent, necessitating a shift in perspective. Third, the precise meaning of scientific practice could be confirmed. This study confirms that scientists use their knowledge effectively in line with the circumstances, and we examined strategies to apply scientific practice to school instruction based on this. Finally, by provoking uncertainty, the Sontanda phenomena may give students with an opportunity to engage in meaningful scientific involvement. By breaking away from the cookbook experiment, this study expects school experimental education to help in efforts to experience scientific practice.

Congenital central hypoventilation syndrome combined with Hirschsprung disease diagnosed in the neonatal period

최진현,오진희,김종현,고대균,홍승철 대한소아청소년과학회 2006 Clinical and Experimental Pediatrics (CEP) Vol.49 No.4

Congenital central hypoventilation syndrome (CCHS) or Ondine's curse is a very rare sleep disorder that is the result of a congenital failure of the autonomic control of ventilation caused by insensitivity of the chemoreceptor to hypercapnea during sleep. Gastrointestinal motility disorders, particularly a congenital megacolon (Hirschsprung disease) is often combined with CCHS. This combination can be explained by a defect in the migration of neuronal cells from the neural crest (neurocristopathy) during the intrauterine period. A diagnosis of CCHS is made by confirming the failure of adequate ventilation in response to hypercapnea and hypoxia during sleep and the exclusion of other diseases. Young infants frequently show atypical clinical courses, and their conditions are frequently complicated with the long-term sequela of hypoxemic episodes. Therefore, a high index of suspicion and active treatment with mechanical ventilation are important for reducing recurrent hypoxemic episodes in the neonatal period. This paper reports the follow up of a case of CCHS in a neonate who showed frequent intractable apnea and cyanosis and was given artificial mechanical ventilation during sleep. Congenital central hypoventilation syndrome은 혈중 이산화탄소 증가와 저산소에 대한 자율 신경계와 호흡 조절 기능의 선천성 결함으로 호흡의 저환기가 주로 수면시에 발생하는 질환이다. 이는 신경 이주장애 질환(neurocristopathy)에 속한다고 알려져 있으며 선천성 거대결장 등의 질환과 잘 동반된다. 아직까지 확실한 완치법은 없는 상태이고 환아들은 평생을 환기 보조에 의존하여 생존해야 하며 적절한 환기 보조를 통해서 생존 기간을 연장할 수 있다. 저자들은 출생시부터 반복되는 수면시의 무호흡과 청색증이 있는 환아에서 congenital central hypoventilation 및 선천성 거대 결장이 동반된 1례를 경험하였기에 보고하는 바이다.

최진현,최인석 한국회계정보학회 2003 회계정보연구 Vol.20 No.-

The function of environmental accounting is to provide measured data as an adequate measure of business organization’ success on the viewpoint of social climate such as pollution. global warming and acid rain. The environmental accounting is based on the general function of accounting system. Much of the accounting function involves measurements and communication of measured data as they relate to point in time and various segments. The environmental accounting information serve as indices to make possible useful analysis of social problems. The standards of identifying, measuring and disclosure of environmental cost accounting is not setting and the rate and degree of environmental cost information disclosure as supplemental footnotes is very low in Korean construction industry. So, this study is aimed at providing some criteria of the environmental cost accounting in Korean construction industry. The results of this study is as followings. First, the environmental cost accounting information is not disclosed in seventy percentage of Korean construction cooperations. Second, some criteria of the environmental cost accounting are construction capacity and detail major in Korean construction industry Third, .a criterion of construction capacity for distinction in separation of environmental accounting is three million Won in Korea. In conclusion, it is necessary to embody contents and methods of supplemental footnotes in detail and there will be disclosed the qualities and contents of environmental cost in comparable form between business organizations. Therefore, it is necessary to group small cooperations and the others for the new accounting standards in Korean construction industry. 본 연구는 한국의 건설업체들을 대상으로 질문지를 이용한 우편 조사방법을 통해 자료를 수집하고 질문지의 문항구성의 신뢰성과 타당성을 검증하기 위해서는 크론바하의 신뢰계수알파를 이용했다. 그리고 조사된 데이타는 로지스틱 회귀분석을 통해 공시여부에 미치는 영향요인을 검토하고, 죤슨-셰논 거리 분석을 통해서는 환경보전(환경보전에 대한 사회적 책임) 및 환경회계에 대한 인식(환경비용 측정의 중요성, 환경비용 공시의 필요성)에 관한 변수들이 세부업종, 시공능력 (기업규모) 등에 따라 군집이 가능하고 차이들이 존재하는지를 검토하였다. 차이가 존재하는 변수들에 따라 그릅핑된 세부집단별로 환경보전과 오염방지를 위한 여러 가지 회계적 적용방안을 생각해 보았다.

Basics of particle therapy II: relative biological effectiveness

최진현,강진오 대한방사선종양학회 2012 Radiation Oncology Journal Vol.30 No.1

In the previous review, the physical aspect of heavy particles, with a focus on the carbon beam was introduced. Particle beam therapy has many potential advantages for cancer treatment without increasing severe side effects in normal tissue, these kinds of radiation have different biologic characteristics and have advantages over using conventional photon beam radiation during treatment. The relative biological effectiveness (RBE) is used for many biological, clinical endpoints among different radiation types and is the only convenient way to transfer the clinical experience in radiotherapy with photons to another type of radiation therapy. However, the RBE varies dependent on the energy of the beam, the fractionation, cell types, oxygenation status, and the biological endpoint studied. Thus this review describes the concerns about RBE related to particle beam to increase interests of the Korean radiation oncologists’ society.
