Background: Assessment of the radiation doses to which workers are exposed can differ depending on the placement of dosimeters on the body. In addition, it is affected by whether the placement is under or over a shielding apron. This study aimed to evaluate the actual positioning of personal dosimeters on the body, with or without shielding aprons, among radiation workers in Korea. Materials and Methods: We analyzed the survey data, which included demographic characteristics, such as sex, age, occupation, work history, and placement of the personal dosimeter being worn, from a cohort study of Korean radiation workers. We assessed the use of personal dosimeters among workers, stratified by sex, age, working period, starting year of work, and occupation. Results and Discussion: Overall, high compliance (89.1% to 99.0%) with the wearing of dosimeters on the chest was observed regardless of workers' characteristics, such as age, sex, occupation, and work history. However, the placement of dosimeters, either under or over the shielding aprons, was inconsistent. Overall, 40.1% of workers wore dosimeters under their aprons, while the others wore dosimeters over their aprons. This inconsistency indicates that radiation doses are possibly measured differently under the same exposure conditions solely owing to variations in the placement of worn dosimeters. Conclusion: Although a lack of uniformity in dosimeter placement when wearing a shielding apron may not cause serious harm in radiation dose management for workers, the development of detailed guidelines for dosimeter placement may improve the accuracy of dose assessment.

Objectives: The purpose of this study was to design a standardized questionnaire for patients with atopic dermatitis in oriental dermatology. Methods: We selected atopic dermatitis from the evaluation of students' satisfaction conducted by the Department of Oriental Dermatology, Dong-guk University College of Oriental Medicine in 2011. To design the questionnaire for atopic dermatitis, we made up descriptive materials consisting of history of the present illness, patient risk factors, past medical history, personal history, and physical examination. Results: Standardized patients (SP) were used in teaching and practicing interviewing and physical examination skills for students. The SP offers a readily available tool for teaching and evaluating the clinical performance and interpersonal skills of medical students. However, the SP program needs to be more thoroughly researched and developed. Research of pattern identification in atopic dermatitis is needed to design the questionnaire. Conclusions: Using an SP program is strongly recommended to teach and evaluate in oriental medicine clinical clerkships.

A personal portable type electronic dosimeter using silicon PIN photodiode and small GM tube is recently attracting much attention due to its advantages such as an immediate indication function of dose and dose rate, alerting function, and efficient management of radiation exposure history and dose data. We designed and manufactured a semiconductor radiation detector aimed to directly measure X-ray and v-ray irradiated in silicon PIN photodiode, without using high-priced scintillation materials. Using this semiconductor radiation detector, we developed an active electronic dosimeter, which measures the exposure dose using pulse counting method. In this case, it has a shortcoming of over-evaluating the dose that shows the difference between the dose measured with electronic dosimeter and the dose exposed to the human body in a low energy area. We proposed an energy compensation filter and developed a dose conversion algorithm to make both doses indicated on the detector and exposed to the human body proportional to each other, thus enabling a high-precision dose measurement. In order to prove its reliability in conducting personal dose measurement, crucial for protecting against radiation, the implemented electronic dosimeter was evaluated to successfully meet the IEC's criteria, as the KAERI (Korea Atomic Energy Research Institute) conducted test on dose indication accuracy, and linearity, energy and angular dependences.

With the recent trends and the adaptation of further advancement in personal healthcare system leads to develop some application which can work independent and user can operate that application without much interference of physician or any specialist user. To meet these needs, this paper proposes and implements a progressive architecture for the personal healthcare information system. This new architecture will not only play the role of middleware but also provide a analysis tool to process that different sensor data which is collected from different sensors implemented on patient body and environment. After collecting that data, with the help of various developed applications this data can be convert into useful information which will be stored in application server for further use and research. These features can be enabled by simple and effortless interactions of normal users and act autonomously to support their activities. This proposed personal healthcare architecture will also provide analysis report to the doctors and patient or various users for further instructions. The analysis report consists of healthcare data analysis results and history of patients. We are considering healthcare data like ECG, which is an important aspect for basic healthcare need.

In 2020, Yi Hunwoo was discovered as one of the earliest modern architects in Korea. However, his personal life was yet mostly unknown, including the time of his death. The research team ('the team' hereafter) searched for the records of his personal life and professional career. First, his family genealogical chart revealed that he died in 1937. Having located and contacted Yi's direct descendents, the team was able to clarify his family background with the descendants' testimonies. They possess the photographs of him and his family members, including Yi's picture when he was a freshman at the Nagoya Higher Technical School in Japan. The team also identifies his birthplace and the location of his grave as Hadong, Gyeongsangnamdo, Korea. The team visited his project site in Jinju, Gyeonsangnamdo, Korea and obtained more detailed information about the Ilshin Girls' High School, which he designed in 1928. Gyohoan, the congregation records of Cheondogyo, one of the leading religions in Korea during Yi's times, confirmed that he was one of the congregation members. The field research also discovered the house he designed and built in his hometown of Hadong, probably the only surviving architectural project by him. This paper is to report the result of the research on Yi's life and career with the aim of providing materials for further studies in identifying and positioning him more properly in the early 20th century Korean architectural scene.

Volatile organic compounds (VOCs) are an important public health problem throughout the world. Many important questions remain to be addressed in assessing exposure to these compounds. Because they are ubiquitous and highly volatile, special techniques must be applied in the analytical determination of VOCs. Personal exposure measurements are needed to evaluate the relationship between microenvironmental concentrations and actual exposures. It is also important to investigate exposure frequency, duration, and intensity, as well as personal exposure characteristics. In addition to air monitoring, biological monitoring may contribute significantly to risk assessment by allowing estimation of absorbed doses, rather than just the external exposure concentrations, which are evaluated by environmental and personal monitoring. This study was conducted to establish the analytic procedure of VOCs in air, blood, urine and exhaled breath and to evaluate the relationships among these environmental media. The subjects of this study were selected because they are occupationally exposed to high levels of VOCs. Environmental, personal, blood, urine and exhalation samples were collected. Purge ＆ trap, thermal desorber, gas chromatography and mass selective detector were used to analyze the collected samples. Analytical procedures were validated with the“break through test”, 'quot;recovery test for storage and transportation”,“method detection limit test”and“inter-laboratory QA/QC study”. Assessment of halogenated compounds indicted that they were significantly correlated to each other (p value < 0.01). In a similar manner, aromatic compounds were also correlated, except in urine sample. Linear regression was used to evaluate the relationships between personal exposures and environmental concentrations. These relationships for aromatic and halogenated are as follows: Halogen $s_{personal}$ = 3.875+0.068Halogen $s_{environmet}$, ($R^2$= .930) Aromatic $s_{personal}$ = 34217.757-31.266Aromatic $s_{environmet}$, ($R^2$= .821) Multiple regression was used to evaluate the relationship between exposures and various exposure deter-minants including, gender, duration of employment, and smoking history. The results of the regression model-ins for halogens in blood and aromatics in urine are as follows: Halogen $s_{blood}$ = 8.181+0.246Halogen $s_{personal}$+3.975Gender ($R^2$= .925), Aromatic $s_{urine}$ = 249.565+0.135Aromatic $s_{personal}$ -5.651 D.S ($R^2$ = .735), In conclusion, we have established analytic procedures for VOC measurement in biological and environmental samples and have presented data demonstrating relationships between VOCs levels in biological media and environmental samples.

전 지구적으로 주거 이동이 활발해짐에 따라 주거 유동성의 심리사회적 영향에 대한 관심이 증가하고 있다. 그러나 국내에서는 아직까지 이에 관한 연구가 본격적으로 이루어지지 않았다. 이에 주목하여 본 연구에서는 개인의 거주지 이전 경험과 심리적 독립성의 관계를 조명하고자 하였다. 구체적으로, 이 연구에서는 개인의 주거 이동 경험에 따라 가치의 실제 자기 중요도 대 지각된 사회적 중요도(연구 1)와 독특성에 대한 선호도(연구 2)가 어떻게 달라지는지 검증하였다. 그 결과, 주거 이동을 빈번하게 경험하였던 사람들일수록 자신이 타인에 비하여 개인주의적인 가치들은 더 중요하게, 집단주의적인 가치들은 덜 중요하게 여긴다고 지각하며, 독특성을 더욱 강하게 선호한다는 것을 알 수 있었다. 마지막으로, 본 연구의 결과가 주거 유동성과 심리적 독립성의 관계에서 영향의 방향에 관하여 가지는 함의를 논하고 후속 연구 방향을 제안하였다.
