이동일,주영은,Lee, Dong-Il,Choo, Young-Eun 대한생리학회 1973 대한생리학회지 Vol.7 No.2

가토(家兎)의 외경동맥(外頸動脈)의 신장도(伸張度)를 알기 위(爲)하여 좌측(左側) 외경동맥(外經動脈)을 절단(切斷)하여 적출(摘出)하고 전혈질(全血質)과 횡절편(橫切片) 및 종절편(縱切片)을 작성(作成)한 후(後) 생리적식염수(生理的食鹽水) 중(中)에 둔 군(群)과 동일(同一)한 방법(方法)으로서 얻은 각(各) 혈질표본(血質標本)을 0.15 mM 및 0.30 mM의 ATP 용액중(溶液中)에 둔 군(群)에서 각각(各各) 15분(分), 45분(分) 및 75분(分)에서 길이 일장력곡선중(一張力曲線中) 탄성(彈性)의 한계(限界) 내(內)에서 Hooke의 법칙(法則)에 따르는 부위(部位)에서 Young 율(率)을 구(求)하여 서로 비교(比較)하였던 바 다음의 결과(結果)를 얻었다. 1) 가토(家兎) 외경동맥(外經動脈)의 전혈질(全血質)을 생리적식염수(生理的食鹽水)에 둔 군(群)에서는 그 Young 율(率)이 실험시간(實驗時間) 15분(分)에서는 $4.74{\times}10^7 dyne/cm^2$이었으나 45분(分) 및 75분(分)에서는 각각(各各) 4.62 및 $4.13{\times}10^7 dyne/cm^2$이었다. 한편 ATP 0.30mM의 농도(濃度)에서는 0.15mM의 농도(濃度)에 비(比)하여 낮은 Young 율(率)을 나타내었다. 2) 외경동맥(外經動脈)의 횡절편(橫切片)의 Young 율(率)은 생리적식염수중(生理的食鹽水中)에서는 15분(分), 45분(分) 및 75분(分)에서 각각(各各) 4.11, 3.75 및 $3.90{\times}10^7 dyne/cm^2$으로서 15분(分)이 가장 높고 그 후(後)는 큰 변화(變化)가 없는 경향(傾向)이었으나, ATP 첨가(添加)로서는 실험시간(實驗時間)에 따른 변화(變化)는 볼 수 없었다. ATP 첨가(添加)로서는 0.30mM의 농도(濃度)에서 0.15 mM의 농도(濃度)에 비(比)하여 Young 율(率)이 낮았다. 3) 외경동맥(外經動脈)의 종절편(縱切片)의 Young 율(率)은 생리적식염수(生理的食鹽水)에 둔 군(群)에서는 15분(分), 45분(分) 및 75분(分)에서 각각(各各) 2.12, 2.48 및 $2.46{\times}10^7 dyne/cm^2$으로서 실험초기(實驗初期)에 비(比)하여 후기(後期)에서 Young 율(率)이 약간(若干) 높은 경향(傾向)을 나타내었고, 이러한 경향(傾向)은 ATP의 첨가(添加)로서도 비슷하였다. The distensibility of the major arteries has been investigated extensively, but the value expressed as Young Modulus varies widely by the different schools of the investigators, the major reason undoubtedly being the difficulties encountered in the measurement. In the present study, an attempt was made to elucidate the distensibility of the external carotid artery of the rabbit, which was placed in saline immediately after removing from the apparently healthy, normal rabbit without anesthesia. The circular section strip and longitudinal section strip were made from the whole artery, and Young Modulus of the whole artery, circular section and longitudinal section strips was calculated from the length-tension curve of each sample. Also, the similar samples of the artery seperately obtained were placed in ATP solution in the concentration of 0.15 mM and 0.30 mM, and Young Modulus was similary calculated. Experiments were performed at 15,45 and 75 min after the artery was removed from the rabbit, and the results thus obtained are summarized as follows. 1) Young Modulus of the whole external carotid artery of the rabbit in saline was $4.74{\times}10^7dyne/cm^2$ at 15 min, but lower values were obtained at 45 and 75 min, Young Modulus being $4.62{\times}10^7dyne/cm^2\;and\;4.13{\times}10^7dyne/cm^2$, respectively. When the arterial samples were placed in ATP solutions, Young Modulus did not change much throughout the experiment, and lower Young Moduli were obtained in 0.30 mM ATP solution than in 0. 15 mM ATP solution. 2) Young Modulus Of the Circular Section Strip in Saline was $4.11{\times}10^7dyne/Cm^2,\;3.75{\times}10^7dyne/cm^2\;and\;3.90{\times}10^7dyne/cm^2,$ respectively, at 15, 45 and 75 min, the value at 15 min being the highest. However, when the strip was placed in ATP solutions, no appreciable change was observed throughout the experiment, and Young Moduli were lower in 0.30 mM ATP solution than in 0.15 mM ATP solution. 3) Young Modulus of the longitudinal section strip in saline was $2.12{\times}10^7dyne/cm^2,\;2.48{\times}10^7dyne/cm^2\;and\;2.46{\times}10^7dyne/cm^2$, respectively, at 15, 45 and 75 min, Young Modulus being slightly elevated in the latter part of the experiment. A similar tendency was observed when the strip was placed in ATP solutions.

We developed a 2-channel fiber-optic temperature sensor (FOTS) using a temperature sensing probe, a fiber-optic coupler, transmitting optical fiber, and an optical time domain reflectometer (OTDR). The temperature sensing probe is divided into a sensing probe and a reference probe for accurate thermometry. A sensing probe is composed of a silicon oil, a FC terminator, a brass pipe, and a singlemode optical fiber and the structure of a reference probe is identical with that of the sensing probe excluding a silicon oil. In this study, we measured the modified optical powers of the light signals reflected from the temperature sensing probe placed inside of the water with a thermal variation from 5 to 70oC. Although the optical power of the reference probe was constant regardless of the temperature change, the optical power of the sensing probe decreased linearly as the temperature increased. As experimental results, the FOTS using a subtraction method showed a small difference (i.e., hysteresis) in its response due to heating and cooling. The reversibility and reproducibility of the FOTS were also evaluated.

Eun-Hyeon Jo(조은현),Dong-Hyung Lee(이동형) 한국산업경영시스템학회 2017 한국산업경영시스템학회지 Vol.40 No.3

The purpose of this study is to find and compare the differences in stress level, stressor, and coping style of high school students according to their personality traits. And to identify the personality traits contributing to stress reduction. The results of the study can be used as basic data for reducing the stress of adolescents to improve their academic achievement and maintain mental and physical stability. The questionnaire survey was conducted for 10 days from June 7 to June 16, 2017 for S high school students in Chungbuk Province. The study employed four measuring instruments as Ego-gram, Ok-gram, stressor scale, and stress coping type scale. Individual personality traits were classified into ego-states and ok-states in TA (Transactional Analysis). Stressors are classified into 5 categories (school life, home life, human relationship, myself, environment) and stress coping styles are classified into 4 categories (problem-focused coping, social-support coping, feeling-focused coping, hope-thinking coping) used in the previous studies. The collected data were analyzed using T-test, ANOVA, and multiple regression analysis. As a result, the stress level of high school students showed significant differences according to sex, year, grade, sleeping time, personality traits, and coping styles. Personality traits that contributed to the stress increase were NP, AC, ‘you positive’, ‘i negative’ and personality trait that contributes to stress reduction is ‘you negative.’ Therefore, we can judge that individual personality traits have significant effects on stress level, stressor, and coping style and need to find the effective stress management method suitable for individual personality traits using counseling, repetition training, self-suggestion etc.

This paper presents a system architecture and database of construction quality management system which encourages real time information tracking and monitoring. It improves the real time quality record tracking by using QR code technology in the project delivery. The advantages and issues relative to QR code and the database structures of the tracking system are presented. Conventional project scheduling system, operation modeling and analysis system, and quality management system are hybridized using QR code technology. The system improves project quality management by tracking the atomic tasks which consists of a construction process at the lowest level of construction hierarchy. It analyzes the quality records to determine the causes of abnormality and/or nonconformity. Using QR code technology, the construction quality management system may be more effective than the conventional one. It was confirmed that the quality management processes in construction project delivery can be more visible and controllable by integrating QR code technology, project scheduling system, and quality management system.

설계시공 일괄계약자(Design/Build Contractor) 선정을 위한 확률ㆍ통계적 품질기능전개 기법

이동은(Lee Dong-Eun),임태경(Lim Tae-Kyung),손창백(Son Chang-Baek) 대한건축학회 2007 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.27 No.1

This paper presents an automated method called Stochastic Quality Function Deployment (SQFD). SQFD is the model that estimates the Quality Performance Index (QPI) of Design/Build (D/B) contractor who enter into the project bidding to pursue commission for the project contracted with Design/Build. It complements the existing Quality Function Deployment method (QFD) which is intrinsically deterministic. The method implements simulation modeling and analysis techniques so as to effectively deal with the randomness and uncertainty associated with decision making processes. SQFD has the features as follows; (1) Using the measure of Log-likelihood, it finds the best fitting probability distribution function (PDF) along with parameters, which describes most appropriately the data set relative to quality performance. (2) It calculates the minimum number of simulation runs to obtain reliable estimation. (3) It provides a stochastic estimation method to assess the quality performance of D/B contractors. SQFD is implemented in MATLAB program. A comparative study between existing QFD and SQFD was carried out. The validity of SQFD was verified.
