金抗洙,鄭雨光,趙南敦,崔鉉洙 대한금속재료학회 2002 대한금속·재료학회지 Vol.40 No.4

The equilibrium study has been made on the vanadium distribution between CaO-SiO_2-MgO_ast.-Fe_tO slag and liquid iron over the temperature range from 1540℃ to 1640℃. The vanadium distribution ratios(L_v) were approximately larger than phosphorous distribution ratios(L_p) by a factor of 10∼100 times. The L_v dependence on slag composition and temperature was found to be similar to the case of L_p. The vanadium distribution ratio increases with the slag basicity and Fe_tO content in slag, but decreases with the increase of temperature. A linear relationship was observed between logarithm of (V)/{[V][O]^n} (n=2 or 2.5) and (CaO+0.3MgO)/SiO_2. It is assumed that the vanadium ion is in the form of V^4+ or V^5+ in slag. The mutual function relating the slag components, F_s=0.58(CaO/ SiO_2)+0.025Fe_tO, was introduced to explain quantitatively the influence of slag composition on the vanadium distribution ratio. The log values of vanadium distribution ratio as a function of Fs were derived at the fixed temerature of 1590℃ and 1640℃.

朴興秀 成均館大學校 1967 論文集 Vol.12 No.-

世宗大王이 우리 나라 音樂의 標準이 되는 基本音을 制定하기 爲하여 朴堧을 시켜 黃鍾尺을 만들게 했다. 그 자를 筆者가 再現시켜 그 자로 9寸 길이인 管長과 9分의 空圍를 가지는 管을 Brass로써 만들었다. 이 管의 1端을 막고 불었더니 振動數가 269.3cps인 소리를 내는 것을 밝혔다. 또 옛 樂器인 李朝玉笛과 編鍾, 編磐의 基本音도 269.0 cps에 極히 잘 一致함을 밝혔다. 또 現行 國樂도 全部 基本音을 269.0 cps로 했을 때의 12청소리에사 基(宮)音을 두고 있음이 밝혀졌다. 따라서 從前에 부르던 宗廟樂, 宴樂, 散調, 唱樂들은 모두 같은 基本音에 청만 달리한 것임이 밝혀졌고, 아울러 國樂의 基本音은 예부터 今日까지 꼭 같은 269.0 cps 로 되어 있음을 밝혔다. From the investigation of the Whang-Chong scale it is found that the frequency of Whang-Chong tone, which is the fundamental of Korean Music and had been adopted in the 7th of Sejong, is 269.0 c/s. In addition to this we find that the fundamental in the middle of Lee dynasty and of the actual Korean Music is also 269 c/s. So we can conclude that the fundamental of Korean Music has been unchanged for the last 530 years.

기존의 특수건강진단과 작업환경측정을 통한 직업병 관리가 진폐증, 소음성난청 등의 소수 특정질환에 국한되고 실제 직업병 발생 규모 파악이나 신종 직업병의 발견에 한계를 보인다는 사실은 산업의학전문가들 사이에서도 공감을 이루고 있다. 미국과 영국 등에서의 직업성질환 감시체계에 대한 경험은 우리 나라의 직업성질환 감시체계 구축에도 새로운 자극제가 되면서, 1998년이후 인천, 대전, 여천, 구미, 부울경 지역에서 지역 직업성질환감시체계를 산업보건관리의 중요한 시스템으로 구축하려는 노력이 확산되고 있다. 새로이 구축되어지는 이들 지역 직업성질환 감시체계는 감시하고자 하는 대상질환, 활용 가능한 인적자원 및 자료원, 지역 의료체계의 특수성 등에 따라서 목적과 방법을 달리하면서 독특한 형태로 발전을 하고 있다. 각 지역단위 감시체계들이 그 상황에 맞게 독특한 목적과 전략들을 발전 시키면서도, 향후 발전할 국가적인 차원의 직업성질환 감시체계 구축을 위하여 직업성질환 감시의 기본 전략 등을 공유하는 등의 노력이 필요하다. 환례 정의 및 기본적인 등록 서식의 공유, 직업성질환 감시 자료원의 발굴, 공동의 정보 네트워크 및 직업성질환 감시 데이터베이스 구축 등 직업성질환 감시활동을 지원하기 위한 여러 기초 인프라 구축에 힘을 모아야 할 것이다. 우리 나라에서 직업성질환 감시체계를 성공적으로 구축하기 위해서는 수집된 자료의 질 관리를 위한 직업성질환 감시의 원칙 제정과 감시 전략의 공유 등이 필요하며, 전국적인 직업성질환 감시체계의 하부구조라고 할 수 있는 지역감시체계의 기초 토대 마련과 강화작업이 절실하게 필요하다.

Survey on milk consumption of Daegu citizen was carried to get information for the increasing milk demand in Korea. Eighty percent of the families was found to consume milk, and 87.0 percent of the milk-drinking families stored the milk in a refrigerator. Reason of milk-drinking was appeared to be 44.0 percent for health, 39.0 percent for children's nutritional source and 14.2 percent for children's favor. The reason why the milk is not consumed was found to be 24 percent for high price of milk, 24.6 percent for yoghurt or egg consumption instead of milk and 16.2 percent for undesirable flavor of milk. The desirable milk pack was found to be 60.7 percent for cartoon pack, 29.2 percent for bottle and 10.1 percent for poly pack.

現行國樂의 音階에 關한 硏究

朴興秀 成均館大學校 1966 論文集 Vol.11 No.-

現行 國樂의 代表演奏家들의 演奏를 測定分析하여 國樂音階를 決定하였다. 測定結果는 雅樂이나 正樂이나 散調를 莫論하고 全部 同一한 音階였는데, 그 音階는 옛날의 國樂의 音階였든 完全五度와 完全四度만으로 構成된 純正音階였다. 또 基本音의 振動數는 文廟樂은 275.8cps, 宗廟樂은 262.7cps, 정악대금은 331.0cps 산조대금은 383.5cps였다. We, for the first time, determine the present musical scale by analysing precisely and by taking an accurate measurement of a musical performance of many typical players in Korean music. By the investigation of these results we find out that the Royal train music, the classical music and the folk music come to all the same musical scale. According to this conclusion, the musical scale is the natural musical scale which is formed by the Fifth and the Fourth, and which is characteristics of musical scale in classical Korean music. As the results, we confirm that the frequency of standard tone is as follows as 275.8 cps in Mun Myo music, 262.7 cps in Chong Myo music, 331.0 cps in Dae Kum for a classical music and 383.5 cps in Dae Kum for a folk music.

國樂音階의 史的인 硏究

朴興秀 成均館大學校 1966 論文集 Vol.11 No.-

世宗大王이 韓國 固有의 黃鐘尺을 만들어, 그것의 9寸의 길이와 9分의 空圍를 가지는 1個의 管을 만드려 1端을 막고 부렀을 때 내는 소리를 樂音의 基本으로 하고 이 音을 黃鐘音이라 했다. 이 音을 基本으로 하여 1 Octave 사이에다 完全五度를 反復해서 얻어지는 12音을 配置하여 12律로 하고, 그 中 5音을 擇하여 5音階로 定했다. 그런데 現在로선 標準이 된 黃鐘尺도 黃鐘律管도 없어저서 當時音階를 再生할수 없게 되였으므로, 當時의 黃鐘尺을 硏究再生 하여 黃鐘律管을 만드렀다. 또 當時에도 이미 管口補正이 되고 있기는 했지만 正確하질못해서 λ/D가 20∼126 사이까지의 管口補正値를 測定하여 實驗的으로 補正曲線을 만들어 完全히 管口補正된 12律管을 만들수있게 하였다. About 550 years ago Sejong the great king (1397-1450) adopted Whang-Chong scale as the Korean own standard of length. Then he designed one of pipe, of which the inner diameter and length were 15/1000 and 9/10 of a Whang-chong scale respectively, and the emitted sound using this pipe was adopted for the standard of musical tone by him and was called Whang-Chong tone. The eleven tones which was obtained by repeating the Fifth step between the Whang-Chong tone and it's one octave upper was arranged as the interval and he made a characteristic Korean musical scale by selecting the five tones among this intervas. With the passing of time, however, the standard of both kinds were disapeared altogether, so we cannot regenerate these musical scale correctly at this moment. In this paper we begin with recovering the Whang-Chong scale at first and try to regenerate the musical scale in the present usage and aim to renew the Whang-Chong pipe in accordance with the original one. It seems also that the end correction of pipe was made in some extent in those days already, but it is no wonder that the correction was not perfect. We measurd the end correction experimentaly from 20 to 126 on λ/D and using these data get sufficiently corrected twelve pipes which represent the original interval.

최항문,유동수 大韓口腔顎顔面 放射線學會 1995 Imaging Science in Dentistry Vol.25 No.2

The purpose of this study was comparision of conventional tomography with reformatted computed tomography for dental implant in locating the mandibular canal. Five dogs were used and after conventional tomographs and reformatted computed tomographs were taken, four dentist traced all films. Mandibles were sectioned with 2mm slice thickness and the sections were then radiographed(contact radiography). Each radiographic image was traced and linear measurements were made from mandibular canal to alveolar crest, buccal cortex, lingual cortex, and inferior border. Following results were acquired : 1. Reformatted computed tomographs were exacter than conventional tomography by alveolar crest to canal length of -0.6mm difference between real values and radiographs. 2. The average measurements of buccal cortex to mandibular canal width and lingual cortex to mandibular canal width of conventional tomographs were exacter than reformatted computed tomographs, but standard deviations were higher than reformatted computed tomographs. 3. Standard deviations of reformatted computed tomographs were lower than conventional tomographs at all comparing sites 4. At reformatted computed tomography 62.5% of the measurements performed were within ±1mm of the true value, and at conventional tomography 24.1% were. 5. Mandibular canal invisibility was 0.8% at reformatted computed tomography and 9.2% at conventional tomography. Reformatted computed tomography has been shown to be more useful radiographic technique for assessment of the mandibular canal than conventional tomography.

심항섭,장경수,조용성,전무형 충남대학교 수의과대학 동물의과학연구소 1994 動物醫科學硏究誌 Vol.2 No.-

To establish an effective diagnostic measure for detection of the antibodies against Actinobacillus pleuropneumoniae, that is the primary agent of swine pleuropneumoniae, the methods for micro-agglutination test(MAT) and agar-gel immunodiffusion test(AGID) were improved and standarized and the comparative studies were carried out. The results obtained through the experiments were summarized as follows. 1. The rabbit hyperimmune sera to reference serotypes 1 to 6 were cross-tested with MAT and AGID. The range of antibody titers on MAT was 80 to 1280, showing the cross-reaction in serotypes 3, 4, 5 and 6. In AGID, the range of antigen titers was 8 to 32, and cross-reaction was observed in serotype 5. The optimal concentration of antigen MAT were 1.25㎎/㎖ 2. In AGID, the most promising antigen and the buffer for agar-gel were EDTA-treated antigen and 0.05M tris buffer(pH 7.2), respectively. 3. By the tests for 200 swine sera, it was found that the accumulative frequency of positive reaction for the 6 serotypes were 240 in MAT and 163 in AGID. 4. when compared the results of AGID with those of MAT for 200 swine sera, all sera with MAT titier under 20 were negative in AGID. Of the sera with MAT titer 40 and 80, 24.7% and 93.9% were positive in AGID, respectively. All sera with MAT titer over 160 showed positive in AGID. 5. In conclusion, the established MAT showed high sensitivity but low specificity, whereas AGID revealed low sensitivity but high specificity. The established AGID test was considered very efficient for detection of antibodies and serotyping of swine sera.
