The present study reviews the license registration status of dental technicians and dentists from 1970 to 2002, the number of technician members of The Korea Dental Technician Association from 1990 to 2003, and the number of dentist members in 2003. It also considers the yearly membership fluctuations, its growth rates, yearly increase/decrease, the rate of dentist to dental technician, regional distribution of association members, regional yearly increase/decrease of the members, and the regional distribution of dentists and dental technicians. The purpose is to identify and predict the problems in the demand/supply of dental technicians and the regional imbalance of manpower distribution. By doing so, this study attempts to propose the appropriate standard for the supply of dental technicians and point out the necessity of making mid- or long-term plans for ensuring the efficiency of manpower supply and balanced regional distribution. The result is as follows: 1. The number of dental technicians and dentists in 2002 has grown 36.79 and 9.27 times from 1970, and 2.20 and 2.05 times from 1990, respectively. It tool 11 years for the twofold increase of dental technicians from 1990, one year faster than the same increase of dentists. The number of dental technicians per a dentist was the lowest in 1972 (0.21 person), and the highest in 2002 (0.86 person). Specifically, the fastest growth was observed for a year from 1983 (0.47 technician per a dentist) to 1984 (0.6). From 1984 to 1986, the ratio grew by 0.1 every year. Summing up the numbers of dentists and dental technicians who passed the national certification examination, this study predicted the number of dental technicians per a dentist to be 0.88 in 2003, and 0.90 in 2004. 2. From 1990 to 2003, the average distribution of dental technician was 71.76% in the metropolitan areas and 28.24% in other smaller regions. The proportion of dental technicians working in the three major cities (Seoul, Busan, and Daegu) was the lowest in 2001 (52.39%) and the highest in 1996 (62.66%). The majority number of dental technicians who practiced in the metropolitan areas (about 70% of the entire population) were in service in the three major cities. 3. Compared with 1990, the number of dental technicians in 2003 grew 2.28 times in the large cities, and 2.05 times in other smaller regions. The yearly growth rate was the highest in 1994 over the previous year: 26.06% in large cities and 17.86% in the other regions. In the large metropolitan cities, the growth rate was the highest in Incheon (5.8 times for 5 years from 1998 to 2003), In the rest of the regions, the increase of dental technicians was the highest in Gyeonggi (6.5 times from 1990 to 2003). 4. In 2003, as much as 73.40% of all the members of the Korea Dental Technician Association were distributed in the large metropolitan cities, and the rest 26.60% were in other smaller regions. Meanwhile, 54.35% of the dentists practiced in the metropolitan cities, and the rest 45.65% were in service at other regions. This result indicates that more dental technicians than dentists are concentrated in large cities. More than half of all the technician members of the Association are distributed in the three major cities (i.e. Seoul, Busan, Daegu). On the other hand, 42.03% of dentist members are in these three cities and 53.97% of them practice in Seoul, Gyeonggi, and Busan. In 2003, the ratio of dentist to dental technician is 1:0.43 in general, while the ratio is 1:0.58 in the metropolitan cities, and 1:0.43 in other regions. In 2003, 33.30% of all the certified dental technicians are the member of the Korea Dental Technician Association, while 66.82% of all the licensed dentists are its members.

This study seeks the countermeasures for the successful organization of the social welfare labor union after examining social welfare workers' cognizance about a labor union and analyzing the major factors affecting their participation in a labor union. An analysis of social welfare workers' cognizance about the social welfare labor union. demonstrates that (1) most social welfare workers have positive opinions about a labor union organization and the participation in a labor union, (2) a great part of workers prefer forming a labor union and a professional organization together in relation to the organization of social welfare workers, and (3) the effective strategies for the organization of a labor union are in the order of the uplift of social welfare workers' consciousness, the constitution of the basic organizations which propel the formation of a labor union, and the preparation of policy countermeasures which attain the supports of clients and citizens. An analysis of factors affecting the participation in a labor union shows that the attitude toward the participation behavior (positive results), subjective norm (specific individuals), subjective norm (social constituent members), and perceived behavior control in the analysis model, male, lower position in officers, and lower educational attainment in democratic characteristics, and lower democratic and professional managements in officers and longer working hours in labor environmental conditions affect positively the participation in a labor union. These results suggest several assignments for the successful organization of the social welfare labor union. First the activities that make social welfare workers recognize the beneficial results bringing about by the participation in a labor union need to be carried out, second strategies that persuade the influential individuals to supports the participation in a labor union need to be developed, third activities that make the social constituent members understand the ethical, professional, and non-productive characteristics of social service works not to be confronted with the organization of a labor union should be pursued, fourth the organizational environments in which social welfare workers can freely participate in a labor union according to their intentions need to be made up, fifth the policy countermeasures which attain the support of social welfare workers, clients and citizens should be developed and carried out, and finally the basic organizations that effectively propel the formation of a labor union need to be constituted.

This study is aimed at the exploratory research on the influence of the obligation of extension of the retirement age on the baby boom generation. The basic question of this study is about which of the baby boom generation can get how much benefit according as the extension of the retirement age becomes compulsory. The extension of the retirement age is the system that can be applied to regular full-time workers. Accordingly, this study is intending to analyze the characteristics of the workers having a high likelihood for benefits from extension of the retirement age by tracing the economic activity state and labor history of the baby boomers. For this purpose, this study looked into the change of the economic activity state by age cohort of the male baby boomers based on the data for the Korea Labor Panel's 4th(2001) & 17th(2014)year. Using Survival analysis, this study also analyzed who will continue to remain as a regular full-time wage earner. As the result of the analysis, it was found that the more the cohort ages of baby boomers increased, the smaller the probability of remaining as a regular full-time wage earner, and the group who can get benefits from extension of the retirement age was predicted to account for only 11.4% level among the baby boomers. In addition, the result showed that there was a high likelihood of getting more benefits from extension of the retirement age when the baby boomers worked for the government-invested institution, corporate bodies, and government organizations rather than working for private enterprises. Thus, it can be safely said that there might appear a generational conflict due to extension of the retirement age in that such jobs coincide with the ones favored by the rising generation.

Backgroung : The incidence of penicillin-resistant streptococcus pneumoniae(PRSP) accounts for almost 70% of all pneumococcal pneumonia cases in Korea. It is still unclear as to whether the efficacy of penicillin or equally active beta-lactam agents is compromised in PRSP pneumonia. This study investigated the prevalence of PRSP in community-acquired pneumonia and its clinical course. Methods : A total of 42 patients with community-acquired pneumococcal pneumonia were evaluated from July 1999 to May 2001. The cultured strains of Streptococcus pneumoniae were divided into susceptible, intermediately resistant, and resistant strains by an E-test, and the effect of the clinical course was investigated. Results : From a total of 42 patients, 22 (52.4%) patients had an intermediate resistance (MIC $0.1-1{\mu}g/m{\ell}$) and six (14.3%) showed a high resistance ($MIC{\geq}2.0{\mu}g/m{\ell}$) with current penicillin susceptibility categories. However, according to the classification of the DRSPTWG (Drug Resistant Streptococcus pneumoniae Therapeutic Working Group), there were 11 cases (26.2%) of intermediate resistance and no case of high resistance. Under empirical antimicrobial treatment, there was no difference in the clinical outcome between the penicillin susceptible and resistant group. Conclusion : The clinical outcome of PRSP pneumonia with empirical therapy was acceptable. These results suggest that the current MIC breakpoint for penicillin resistance in Streptococcus pneumoniae has been set at a very low level and penicillin resistance according to the NCCLS classification does not significantly influence the outcome of the empirical treatment for pneumococcal pneumonia.

The QuantiFERON-TB Gold assay and tuberculin skin test (TST) have been useful test for diagnosing latent tuberculosis infections (LTBI). However, there are few reports on the efficacy of the QuantiFERON-TB Gold assay and TST in evaluating the response after the treatment of LTBI. This study examined the changes in the TST and QuantiFERON-TB Gold assay before and after a treatment for latent tuberculosis in health care workers (HCWs) at a local tertiary hospital. Methods: A cohort of volunteers working as nurses and doctors who underwent a TST and QuantiFERON-TB Gold assay was established. The volunteers positive for the QuantiFERON-TB Gold assay had been treated with 3 months of isoniazid (INH) and rifampin (RFP). After completing treatment, the TST and QuantiFERON-TB Gold assay were repeated. Results: Of the 48 participants (14 doctors, 34 nurses, M: F=11:37, mean $age=29.9{\pm}5.5$ years, mean employment $period=74.9{\pm}64.3$ months), 19 (39.6%) tested positive to the TST (mean induration=$19.1{\pm}9.7mm$) and 8 (16.7%) were QuantiFERON-TB Gold assay. Among them, one had active pulmonary tuberculosis. Seven volunteers were consistently positive to both the TST and QuantiFERON-TB Gold assay after being medicated with INH and RFP for 3 months. Conclusion: TST and QuantiFERON-TB Gold assay are unsuitable for evaluating the treatment response of LTBI because they were consistently positive both before and after the anti-tuberculosis medication.

The purpose of this study was to define the content of the requisite knowledge of pathophysiology, clinical microbiology, and mechanisms and effects of drugs needed for clinical knowledge for nursing practice. Contents of knowlege on pathological physiology, clinical microbiology, and mechanisms and effects of drugs were constructed from syllabus of basic nursing subjects in 4 colleges of nursing, and textbooks. The degree of need of 72 items was measured with a 4 point scale. The subjects of this study were college-graduated 136 nurses from seven university hospital in Seoul and three in Chonnam Province, Kyungbook Province, and Inchon. They have been working at internal medicine ward, surgical ward, intensive care unit, obstetrics and gynecology ward, pediatrics ward, opthalmology ward, ear, nose, and throat ward, emergency room, rehabilitation ward, cancer ward, and hospice ward. The results were as follows : 1. The highest scored items of the knowledge of pathophysiology, clinical microbiology, and mechanisms and effects of drugs necessary for nursing practice were side effects of drugs, anticoagulants, mechanisms of drugs, antihypertensive drugs, tolerance and addiction of drugs, interactions among drugs, hospital infection in the order of importance. The lowest scored item was structure of microorganisms. 2. The highest order of need according to unit was repair in tissue injury unit, definition etiology classification of inflammation in inflammation unit, transplantation and immunologic response in alterations in immunity unit, thrombus and thrombosis in disorders of cardiovascular function unit, gene disorders in genetic disorders unit, hospital infection in infection unit, virus in microorganisms unit, side reactions of drugs in introduction unit, anticonvulsants in drugs for central nervous system unit, local anesthesia in anesthesia unit, anticoagulants in drugs for cardiovascular system unit, anti-inflammatory drugs in antibiotics unit, anti-ulcer drugs in drugs for digestive system unit, and bronchodilators in drugs for respiratory system unit. 3. The common content of the knowledge of pathophysiology, clinical microbiology, and mechanisms and effects of drugs needed for all clinical areas in nursing were side effects of drugs, anticoagulants, interactions among drugs, and hospital infection. However, the degree of need of each pathological physiology, clinical microbiology, clinical microbiology, and mechanisms and effects of drugs was different depending on clinical areas. 4. Significant differences in the knowledge of pathophysiology, clinical microbiology, and mechanisms and effects of drugs necessary for nursing practice such as tissue changes due to injurious stimuli, degenerative changes of tissue, alterations in metabolism of carbohydrates, ischemia, hyperemia and congestion, hospital infection, structure of microorganism, classification of microorganism, bacteria, virus, antidepressants, antipsychotic drugs, antiemetic drugs, antiparkinsonism drugs, antianxiety drugs, antibiotics, tuberculostatics, antiviral drugs, antifungal drugs, parasiticides, antiulcer drugs, antidiarrheais, and anti constipation drugs were shown according to the work area. 5. Significant differences in the knowledge of pathophysiology, clinical microbiology, and mechanisms and effects of drugs necessary for nursing practice such as transplantation and immunologic response, alterations in the metabolism of uric acid, structure of microorganism, classification of microorganism, immunosuppressants, drugs for congestive heart failure were demonstrated according to the duration of work. Based on these findings, all the 72 items constructed by Korean Academic Society of Basic Nursing science should be included as contents of the knowledge of pathophysiology, clinical microbiology, and mechanisms and effects of drugs.

This paper attempts to define some general characteristics of the Abstracting Journals published in Korea as evidenced in those published during last ten years. This purpose is achieved by comparing the results of the two studies conducted by the author in 1984 and in 1994. Both studies were conducted to present the state of the art in the abstracting services in Korea. The major conclusions made in this paper are summarised as follows： (1) Researchers and professionals working in a small number of subject fields are benefited by the abstracting journals, which provide current-awareness services of recent achievements in research and development in Korea. Those in most of the fields have no abstracting journals of their own, and naturally they have no substantial abstract-ing services. Even many researchers and professionals in the fields that have some abstracting journals are not informed of research results in their fields because the abstracting journals are scattered in many narrow subjects and in many cases, the abstracting journals only cover publications in some specific forms and kinds. (2) Abstracting journals that cover more than two subject fields, which are supposed to be of more or less help to the researchers and professionals in the subject fields that have no abstracting journals published in their fields, have rapidly increased in number in the past ten years. Most of suh abstracting journals carry thesis and dissertation abstracts, and the rest, those of research papers published in specific places, in specific forms, by specific institutions, and of reports of research projects sponsored by specific foundations. These abstracting journals are not of the kind that comprehensively provide researchers in related fields with current awareness of publications of research results in Korea. (3) Most of the abstracting Journals existing in Korea are Published by institutions of higher education and research institutes, and the rest, by commercial publishers, industrial firms, libraries, information centres, government agencies, research foundations, learned societies, etc. Those which publish many titles are small in number and those publish one or two titles are large in number. The former is largely made up of institutions of higher education and research institutes. (4) The abstracting journals published in Korea are classified by type into those of dissertations, research papers, journal articles, patent specifications in that descending order. The fact that Master; and doctoral dissertation abstracts ate dominating in Korea is due to the irrational practice of publishing those abstracts at many different institutions. (5) Most of the abstracting journals existing in Korea are published by national or government-supported research institutes in order to publicise their own research outputs. Their coverage of literature is normally narrow, and naturally their value to users is limited. (6) Korean is the desirable language for the abstracting journals intended to be distributed within Korea. About half of the abstracting jornals published in Korea is printed in Korean and the other half, in foreign languages, and in Korean and in foreign languages together. All the abstracting journals in foreign languages are printed in English except one, which is printed in Japanese. (7) Some twenty per cent of the abstracting journals in Korea is published monthly, bimonthly, and quarterly. The others are published annually, biannually and irregularly. The latter may not function properly as a current-awareness tool due to long intervals between their issues. It is particularly undesirable that about half of the abstracting journals in Korea is published irregularly. Most of the abstracting journals published in Korea are distributed freely to individuals and institutions selected by the publishers. (8) The abstracting journals published by the use of computers increased drastically in the past ten years. The abstracting journals produced by the conventional type-setting method will possibly disappear in Korea in another ten years to come. Automation of the production of abstracting journals does not simply mean technical, economic improvement in publishing processes but availability of machine-readable databases that can be used for many other pur-poses, including generation of other bibliographical publications and provision of machine literature searching capabilities. Necessary steps should be taken for this important development immediately.

This research is intended to identify how office worker's recognition of strength affects the intention of starting a business when it is used as a medium for utilizing strength. The survey period was conducted for two months from January 17, 2019 to March 8, 2019. In order to achieve the object of this study, a significant number of employees have been collected nationwide, and 287 office workers were analyzed after collecting 300 questionaires, excluding 13 office workers who were not sincere. The significant data were analyzed by utilizing the structural equation and technical statistics and by verifying the conformity of structural model and measurement model and by investigating the relationship between variables. The results of this study are summarized as follows: First, employee's perception of strength has been found to have a significant effect on the utilizing of strength. Second, the use of workers' strengths has been found to have a significant effect on the intention of starting a business. Third, it has been confirmed that in the relationship between the employee's perception of strength and intention to start a business, the recognition of strength has a significant effect on the intention of starting a business only through the use of strength. Most office workers are nervous about the future and make various plans. The time to live after retirement is getting longer and jobs and working hours are shrinking at an alarming rate. According to the analysis on the status of small business owners in the mid-term of 2017 data, the average monthly operating profit of small business owners across the country is decreasing over the years, and most start-ups are subsistence-type start-ups, and they decide to start their own businesses because they have no other choice than start-ups. As the number of small business owners suffering from financial difficulties has increased since the financial crisis and insecurity of job is pushing those with financial difficulties after retirement to the battleground of the start-up market, the result of this research suggest that the workers need to recognize their own strength and enhance the importance of utilizing the strength.

Due to the introduction of CR and DR, it has been neglected the use of the X-ray beam collimator and field size. This study examines nationwide survey of the proper use of collimator and field size by area in a specific field of plain radiography and the current status. Authors emphasized the need for the field size criteria, and propose a standard reference field size in each specific radiologic examination. Total 333 medical institutions (included in Seoul, Gyeonggi-do, Jeolla, Chungcheong, Gangwon-do, Busan area), were investigated in relation to the status of the X-ray beam collimation field size, type specific inspection areas, medical facilities, and image analyses by type to figure out whether they use the adjustment of image field to the specific examination. To assess the awareness and the impact of radiation exposure to the collimation adjustable, 168 radiographers who was working in 10 general hospitals, 10 hospitals, and 10 clinics, were surveyed how they haver adjusted the actual field size. We examine that 61.3% of medical institutions used the "Proper collimation" and only 49.9% of them employed proper one in lumbar spine densely crowded by major organs. 69% among general hospitals, and 65% among hospitals using DR system were using proper collimation. Radiographers recognized that proper adjustment of collimation could reduce the harmful radiation dose on patients. In the survey, 97.6% of respondents were aware of this fact, but only 83.3% of respondents did the adjustment of the size of the collimation field. The using of proper collimation field was low in the nationwide survey, so the effort to reduce the radiation dose on the patients is urgently needed. A unified standard for the field accompanied by thorough education should be needed.

For the purpose of reducing the cost for greenhouse operation by acquiring the electric power necessary for it, this study installed a solar photovoltaic system on the roof of the building adjacent to green-houses and experimentally examined the quantity of power generation based on weather conditions. The results of the study are as per the below: The maximum, average and minimum temperature while the experiment was conducted was $0.4{\sim}34.1,\;-6.1{\sim}22.2$, and $-14.1{\sim}16.7^{\circ}C$ respectively, and the solar radiation was $28.8MJ{\cdot}m^{-2}$ (maximum), $14.9MJ{\cdot}m^{-2}$ (average), and $0.6MJ{\cdot}m^{-2}$ (minimum). The quantity of electric power didn't increase in proportion to the quantity of solar radiation and instead, it was almost consistent around 750W. Daily maximum, average and minimum consumption of electric power was 5.2kWh, 2.5kWh and 0kWh respectively. Based on the average electric power consumption of the system used for this experiment, it was sufficient in case the capacity and the working time of a hot blast heater are small, but it was short in case they are big. In case the capacity of the hot blast heater is big, the average electric power quantity will be sufficient for array area $21m^2$, about three times of the present area. In summer when the temperature of the array becomes high, the generation of electric power didn't increase in proportion to the quantity of solar radiation, but this experiment result shows a high correlation between two factors (coefficient of correlation 0.84).
