This study examines and presents reasonable improvement measures for the operation and revision of the relative value scoring system, and the basis for performance of a medical technologist. Seven hospitals were enrolled in the study, and included 5 resident laboratory medicine specialists and 53 medical technologists, giving a ratio of 10.6 technologists per laboratory medicine specialist. The average of professional manpower scores was 18, and the average of each medical institution's total score was 78. Ratings and additional rates were in the range 2~3%, and quality-added ratios were 2~3%, with no significance. Excluding pathological testing and assessing physiological functions, the average number of diagnostic tests for health insurance claims were 9,618,062, including 4,378,146 points for 5% of the total relative value scores. According to the DEA, the appropriate number of medical technologist is one person per 49,974 points of relative value. In conclusion, our study results indicate that it would be desirable to set the appropriate workforce for medical technologist to one person per 50,000 points of relative value. Our data could be used as a basis for enhancing productivity of the workforce and balancing health care resources.

The resource-based relative value scale (RBRVS) compares the value of a medical practice to the consumption of resources, which consist of the work of the physician, practice expenses, and professional liability insurance. At the time of the 2nd revision of RBRVS, the fee for radiological examinations had been reduced due to the high preservation rate. In RBRVS, practice expenses account for most of the compensation of radiological examinations, and physicians' work is relatively undervalued. A new healthcare policy (Moon Jae-In care) consists of the expansion of the National Health Insurance (NHI) coverage, reduction of patient charges for the vulnerable class, and support for catastrophic medical expenses. However, Moon Jae-In care is expected to negatively affect the NHI in Korea financially. The expansion of the insurance coverage for ultrasonography and MRI examinations is a significant part of the Moon Jae-In care, and radiological societies should establish fair compensations for physicians' work within the field of radiology while implementing the Moon Jae-In care.

Run expectancy (RE) is the mean number of runs scored from a specific base runner/outs situation of an inning to the end of the inning. Win expectancy (WE) is the probability that a particular team will win the game at a specific game state such as half-inning, score difference, outs, and/or runners on base. In this paper, we derive RE and WE for the Korea Baseball Organization (KBO) League based on six-year data from 2007 to 2012 using a Markov chain model.

In the health care system, medical fee payment is a very important and basic factor. The National Health Insurance Act adopted a contract system, and the content of the contract is to be determined the unit price per relative value scale. Accordingly, in the National Health Insurance system, the costs of health care benefits are adjusted each year according to inflation or changes in economic conditions. On the other hand, in the Medical Care Assistance system, the Medical Care Assistance Act does not prescribe the method of determining the medical payment, and all matters are delegated to the Minister of Health and Welfare. Accordingly, the Minister has adopted a fixed-payment system for hemodialysis treatment since 2001. A constitutional petition was filed in 2017 against this fixed-payment system, and the Constitutional Court rejected the petition in 2020. In this study, we examine the meaning and content of the medical fee payment system, focusing on the above constitutional petition case, and present three principles as constitutional limits on the system. The first of its principles is the principle of legality, the second is the principle of prohibition of comprehensive delegation, and the third is the principle of proportionality. From that point of view, There are many unconstitutional elements in the fixed-payment system on hemodialysis.

This study was carried out to grade and evaluate the intertidal mudflat by birds. The mudflat was graded by two methods such as the scoring and ranking. First, for the scoring of the mudflat, five factors were estimated; population size, the number of protected species, the individuals of protected birds, the number of species(or subspecies) over 1% level of the survival population, and 1% level of the domestic population. After scoring of these five factors, the grade was scored by total. Second, for the ranking, six factors were estimated; population size, the density of birds, the index of species diversity, species richness, species evenness, and population stability. After ranking of these six factors, the grade was relatively ranked. Five grade by scoring was the important mudflat for the value of international preservation, and the most mudflats of the estuary gained V grade. The higher grades by ranking were the mudflats of Nakdonggang and Mankyunggang river estuaries. And the inner mudflats were more valuable than the outer mudflats in Mankyunggang & Dongjingang river estuaries. The grading of the mudflat by birds can be used for estimating and appointing of the important mudflats, and suggested the objective of criteria for the effective preservation and management.

This study investigates the current situation of medical technologists for blood collection, which is considered the most important step for diagnosis. The survey enrolled 650 medical technologists working in hospitals and medical check centers in Busan, Ulsan, and Gyeongnam. We found that each medical technologist performed blood collection for about 100 patients. There was more than one blood collection failure per day, with more than one case of pain and filing of civil complaints per year. Hence, there was a high work burden on the medical technologists. Cases where a medical technologist was stabbed with a used needle occurred more than once a year, and about 15% of them received infection control and treatment because of stab wounds. Additionally, more than half of the participants suffered from musculoskeletal disorders and mental stress due to blood collection work. Unlike administering intravenous and intramuscular injections using the same needle, no fee is charged for blood collection. Based on the results of this study, it will be possible to improve the safety and rights of medical technologists by calculating the actual fee for blood collection work and assigning a relative value score.

In this study, by analyzing the examination time for each procedure, the appropriate workload of radiologic technologist is analyzed based on the actual examination time in the current clinical setting by comparing with the examination time in the radiology field setting of the health insurance review and assessment service. In addition, this result is introduced into the calculation of relate value units; it was attempted to provide accurate and objective evidence in the field of radiology. From May 2020 to December 2021, the study retrospectively investigated the examination times recorded in the electronic medical record and picture archiving and communication system at 5 tertiary general hospitals and 1 general hospital. The total of 16 examination parts are applied in this study, including the head, sinuses, chest, ribs, abdomen, pelvis, cervical, thoracic, lumbar, shoulder, elbow, wrist, hip, femur, knee, and ankle. The minimum number of images that could be obtained per radiation generator was 3.6 images for one hour, and the maximum was 6.4 images. When 50% median of procedure time is calculated, the minimum number of images that could be obtained was 16.7 images and maximum was 35.3 images; in addition, minimum examination time is 1.7 minutes, and maximum time is 3.6 minutes. In conclusion, it is judged that there will be insufficient explanation time for basic infection instructions such as hand hygiene during the examinations in current clinical practice. It is believed that radiologic technologists will contribute to providing higher-quality of radiation examination services to the public by complying with guidelines for work and setting appropriate workload on their own.

Peer assessment is an educational valuation system that involves studying with a colleague and granting value to the progress made by the colleague. Although this method has many merits, there is also a drawback pertaining to calculating the mean of the scores that were granted to the levels of contribution. However, this has been improved upon by a diversified study. However, the concept of the chi-square test and p-value used in the preceding study is not easy individuals engaged in the industrial engineering field or education when using peer assessment. This study uses simple statistics like standard deviation, in addition to, investigating the availability of a suggested method as well as examples of utility and application. This study can contribute to increase the convenience of users through the use of convenience analysis and with this method.

This study was intended to investigate physical characteristics of the bread with Laminaria powder. Three different powder concentration levels of 2.5%, 5% and 7.5% were added to flour to make the bread. The puffing rate, density, color, and texture were analyzed. Sensory evaluation was performed among female college students and housewives in their 50s. The volume of the dough during the fermentation and the final volume of the bread containing Laminaria powder was smaller than that of the dough without the powder. While adding the powder to the bread decreased the Hunter L (lightness) and a value (redness), it increased the b value (yellowness). In the texture analyzer measurement, hardness and fracturability of the bread were significantly increased by adding the powder and chewiness tended to increase. However, adhesiveness, springiness and cohesiveness were not significantly different among groups. As the result of the sensory evaluation, differences were observed between female college students and housewives in their 50s. In all indices of the sensory test, college students evaluated the bread with the powder lower than the bread without the powder, while the housewives preferred the bread with the powder. The bread containing 2.5% Laminaria powder obtained the most excellent scores. In conclusion, it is suggested that the bread with 2.5% Laminaria powder would be a highly acceptable bio-active product with proper physical characteristics.

It is a global trend that the water management policy is shifting from a water quality-oriented assessment to the aquatic ecosystem-based assessment. The majority of aquatic ecosystem assessment systems were developed solely based on physicochemical factors (e.g., water quality and bed structure) and a limited number of organisms (e.g., plankton and benthic organisms). Only a few systems use plants for a health assessment, although plants are sensitive indicators reflecting long-term disturbances and alterations in water regimes. The development of an assessment system is underway to evaluate and manage lakes as ecosystem units in the Korean Ministry of Environment. We reviewed the existing multivariate health assessment methods of other leading countries, and discussed their applicability to Korean lakes. The application of multivariate assessment methods is costly and time consuming, in addition to the correlation problem among variables. However, a single variable is not available at this moment, and the multivariate method is an appropriate system due to its multidimensional evaluation and cumulative data generation. We, therefore, discussed multivariate assessment methods in three steps: selecting metrics, scoring metrics and assessing indices. In the step of selecting metrics, the best available metrics are species-related variables, such as composition and abundance, as well as richness and diversity. Indicator species, such as sensitive species, are the most frequently used in other countries, but their system of classification in Korea is not yet complete. In terms of scoring metrics, the lack of reference lakes with little anthropogenic impact make this step difficult, and therefore, the use of relative scores among the investigated lakes is a suitable alternative. Overall, in spite of several limitations, the development of a plant-based multivariate assessment method in Korea is possible using mostly field research data. Later, it could be improved based on qualitative metrics on plant species, and with the emergence of further survey data.
