Researches on laboratory work show that students often achieve little meaningful learning through laboratory work. One reason for this failure is that students often do not know the different types of laboratory work and the 'purposes' of them. Therefore, this study investigated middle school student' ideas about the purposes of laboratory work. To seventh grade students(n=147) of middle school in Seoul, Korea, we asked (Question 1) "Why do scientists do laboratory work?" and (Question 2) "Why do you do laboratory work in science classes?" It was required a short essay including the reasons and examples of them. From the results, it was found that 56.8% of the students had ideas that scientists do laboratory work for discovering new facts or inventing something, and 82.9% of the students responded that they do laboratory work for understanding and memorizing the contents of science textbook. In addition, the differences according to gender and to school achievement level, and the relationship between the ideas about scientists' laboratory work and about school science laboratory work were examined. The results showed that boys responded 'social usefulness' more frequently than girl, while girls mentioned 'personal pleasure' more frequently than boys in relation to the purposes of scientists' laboratory work(p<.05). According to the achievement level, it was founded that 'middle' level students replied 'to remember' more frequently than high and low levels in relation to school science laboratory work. Finally, students who had ideas that scientists do laboratory work for verifying a theory had the similar ideas about school science laboratory work. In conclusion, students are lack of diverse and proper views about laboratory work. It is recommended that teacher need to make clear the purpose of laboratory work and help students to understand of it.

Clinical laboratory testing plays a crucial role in the detection, diagnosis, and treatment of disease. Clinical laboratory scientists evaluate test results, develop and modify procedures, and establish and monitor programs, to ensure the accuracy of tests. It is clear that over the past decade the role of the clinical laboratory scientists has expanded and this process will be continued into the future. The purpose of this study is to clarify the factors influencing the job performance of clinical laboratory scientists and aim to provide the role and duties of clinical laboratory scientists. To examine the frequency of work context and the importance of task, the surveys were conducted on 168 clinical laboratory scientists. The questionnaire items were used 10 score by Likert scale. According to the results of this study, the important factor affecting the job performance was "Analyze laboratory findings to check the accuracy of the results", and the next factors were "Establish and monitor quality assurance programs", "Enter data from analyzer into computer", "Calibrate and maintain equipment". And the factors of "repeating same tasks" and "spend time making repetitive motions" were answered the highest. This study will provide strategies for improving work environment, developing education curriculum and method, and role of clinical laboratory scientists. We must continually upgrade our knowledge, and identify the new trends in technology and science and accept changes.

The purpose of this study is to provide the basic guidelines of spatial and physical environment for the planning and design of clinical laboratory by analysing the extent of satisfaction of clinical laboratory scientists. The data for this analysis was gathered from March to May 2005 by the questionnaires of 208 clinical laboratory scientists who work in the 13 hospitals. All the collected data was analyzed by the SPSSWIN program. In this study, the satisfaction measurement tool was composed with 8 items and 5 score scale. The mean score of satisfaction for spatial and physical environment was 2.89 out of 5.0, "noise" was the lowest 2.40, "temperature and moisture of the lab." was 2.72, "lab. area, service area and administration area" was 2.77, "passageway space" was 2.94, circulation of workers was 2.94, "color of finish" was 3.19, "lighting of lab." was the highest 3.39. In conclusion, various factors, noise, temperature and moisture, clinical lab area, were evaluated to moderate dissatisfaction. Noise was especially the first serious problem in clinical lab. Considering the high growth of the number of tests, the planning of the clinical laboratory size should be considered not only to provide the optimal size but how it will correspond to the growth of the number of tests. Therefore the arrangement of each section need to be flexible in arrangement which is inevitable in expansion and reconstruction in the future.

The purpose of this study is to obtain science high school students' perceptions of scientists and their work before and after the Green Investigation program with scientists. This study also attempts to determine whether the program affected the participants' perceptions of scientists and their work. A modified DAST was carried out with 64 high school students. Findings revealed that Korean science high school students had normal perceptions of scientists, such as images of 20 to 30 year old males wearing laboratory coats and working alone in research labs with test tubes, flasks, and several machines in the background. After the intervention, students drew fewer typical items representing scientists and had significantly different perceptions of their work places between the pretest (M=1.69, SD=1.14) and posttest (M=1.96, SD=1.24, t=4.43, p<0.001) with the eta squared statistics (.24). These findings reflect the need for continued efforts of developing green investigation programs with scientists for students. Some future studies based on this study are also introduced.

With increasing interest on scientists and the influence of science technology, their role in the modem society has been expanding. Scientists work in the laboratory as researchers, work in their expertise area as professionals, and work socially as social agents. Scientists are responsible to keep up the regulations during the research, and also are responsible for the results of the research. Therefore, there is a need of contemplation in terms of what their identity is and what their responsibilities are. Despite of this need, there hasn't been much discussion or education on the scientists social role or responsibilities as of now. This study purported to contemplate on the scientists role and responsibility, its qualification, and what it means to be a scientist as a social agent. Also the study further explored the efficient educational strategies and methods relevant to the contemplated issues.

Recording of the research procedure and results is the compulsory virtue to scientists. This ensures the objectivity and integrity of research and has become a cornerstone for a junior scholar. Furthermore, we can save time and efforts by avoiding duplication study. Recently on its patent application, the value of laboratory notebook is going to increase. However, there is a limitation to record a voluminous work in a traditional writing laboratory notebook. So, it could be an alternative proposal to convert that into an electronic work or develop an electronic laboratory notebook. Our journal has continuously pursued globalization. Laboratory notebook could be one of the key factors for that goal. In the present study, the authors reviewed the needs for laboratory notebook and tried developing a proto-type electronic laboratory notebook.

This study explored the method of determining the appropriate size of the workforce according to the assessment of the workload of medical technologists (also called medical and clinical laboratory technologists, and medical and clinical laboratory scientists) in order to present a standard production model for the appropriate manpower in blood collection rooms. The eleven university hospitals selected for this study had between 600 and 2,000 beds. The 14-steps standard blood collection time was 4 minutes and 8 seconds for the outpatients aged between 20 to 60 years old (57%) except for children and the elderly (43%). Assuming that there were 8 hours per day for mechanically collecting blood, the maximum number of blood donations by one clinical laboratory scientist was analyzed to be 100 cases. In conclusion, it is appropriate to have fewer than 100 cases of daily blood collection by a medical technologist engaged in blood collection. Since the proper number of blood collection workers (100% of blood collection work)=the number of annual working days/(one day's work hours/time per case)×the number of working days per year, then the proper number of blood collection workers (one day's work hours)=the number of working days per year/100×the number of working days).

The production of matrix matalloproteinases(MMPs) by the UV irradiated skin fibroblast and the degradation of extracellular matrix(ECM) by these enzymes is known as one of the main reasons of photoaging. Recently, Fisher group showed that the MMP expression is mainly regulated by the mitogen-activated protein(MAP) kinas family, such as extracellular signal-regulated kinase(ERK), c-Jun amino-terminal kinase(JNK) and p38, each of which forms a signaling pathway. In this work we first examined the effect of nitric oxide (NO) on the production of MMP-1 and MMP-2 by the human dermal fibroblasts (HDFs). NO is a multifunctional messenger molecule generated from L-arginine and involved in many kinds of signaling pathway. We found that the treatment of HDF with NO donor, sodium nitroprusside (SNP) enhanced the expression of MMPs with or without UV irradiation and the treatment with nitric oxide synthase (NOS) inhibitors resulted in the significant decrease of MMPs production. From these results, we concluded that the production of MMPs by the UV irradiated HDF is regulated through the signaling pathway involving NO and cyclic GMP.

In recent years, medical practice has seen a drastic change due to the rapid, exponential expansion of scientific and medical technologies. Specially, the role of medical technologists (also known as medical laboratory scientists and/or clinical laboratory scientists) are increasing in the development of science of medical technology. As such, their responsibility has also been increasing. Therefore, given their highly specialized knowledge and skills, they are not regarded solely as doctor's assistants. Their independence and deeper specialization have been increasing, as they perform medial practices under the guidance of doctors or dentists pursuant to the "Act on Medical Service Technologists." From a legal point of view, medical guidance and scope of work were examined. As a conclusion, the definition of doctor's superintendency on the "Act on Medical Service Technologists" is required, and the qualification for the Korean license examination and their roles should be stated clearly. Moreover, communications among health professions regarding the roles of medical technologists are necessary to further facilitate clarification of their role. There is a need for independent legislation to expand the field of medical technologists and to strengthen their professionalism.
