Background & Objectives : As the government of South Korea implemented policies to strengthen health insurance coverage, the health insurance benefit for raw herbal medicines has been promoted. This study investigated the current status of the herbal medicines coverage in the Japanese national health insurance to secure reference data for the design of herbal medicines coverage in South Korea. Methods : Literature review was conducted to collect and analyze the history and current situation on herbal medicines coverage in the Japanese health insurance system. To supplement the contents not presented in the documents, on-site interviews were conducted at the medical institutions and pharmacies that prescribed or prepared herbal medicines in Tokyo, Japan. The contents of the survey included the background and progress of the herbal medicines coverage, the status of herbal medicines use, the payment system, and the safety management of herbal medicines. Results : Since the introduction of health insurance in the 1960s, Japanese insurance system has covered herbal medicines, and so far, it has been maintained without any additional restrictions. When the raw herbal medicines are prescribed to outpatients, the preparation fee is set higher than that of other medicines, but overall payment regulations and systems for herbal medicine are generally the same as other medicines. Conclusions : The case of Japan can be a useful references and implications for national health insurance policy on herbal medicines in south Korea.

This study was designed to help develop an optimized sizing system for the military winter jackets of Korean males. First, we conducted a survey on the supply rate of military winter jackets and the wearing of suitable size jackets in order to identify problems in the current sizing system. We next developed a new sizing system generation method to satisfy the coverage rate and appropriate size number: Hybrid of Grid with Optimization. The findings of this study were: 1. The survey indicated that a 90 (chest girth) size is necessary; in addition, a one-step large size jacket fit well as a right size jacket. 2. We developed three optimized sizing systems for Korean male military winter jackets using the Hybrid of Grid with an optimization method and suggested one of them as a final new sizing system. The new sizing system consisted of two primary dimension: chest girth and stature. It has a 14 size number and its extended coverage rate is larger than the current sizing system and it has a 90 (chest girth) size. It also selected an optimized size for the area of low population density. The new sizing system is therefore considered very effective for Korean male soldiers military winter jackets.

Influenza vaccination in adolescents is crucial to prevent the influenza expansion. The aim of this study was to investigate the difference of personal factors and parental factors affected influenza vaccination coverage. Study data on 12-18 years old adolescents and their parents were obtained from the 6th Korea National Health and Nutrition Examination Survey. Rao-Scott Chi-square test and multivariate logistic regression were used for the analysis. The percentage of influenza vaccination coverage in adolescents was low (26.2%). The personal factors influencing influenza vaccination were age, discomfort within two weeks, history of pneumonia, and wearing safety belt in adolescents, and the parental factors were age and influenza vaccination. In order to increase the influenza vaccination coverage for adolescents, media and healthcare professionals should provide education to adolescents and their parents about influenza vaccination.

The degree of income inequality deepened by health care expenditure was useful in assessing the health security level. This exploratory study was conducted to provide a basic evidence to prove the necessity of reinforcement the benefit coverage of South Korea's health security systems. Data from the Household Income and Expenditure Survey of Korea and Luxembourg Income Study were used. Income inequality indices before and after deduction of health care expenditure were computed, and the degree of the increase in the indices was compared among 13 countries. The degree of decrease against the effect of income inequality reduction policies by health care expenditure was determined. The relationships between the national characteristics and the increase in income inequality were examined. In South Korea, all income inequality indices increased after deducting health care expenditure, but the difference was not high compared to the mean of 13 countries. However, the degree of decrease against the effect of income inequality reduction policies by health care expenditure was high, compared to the mean of 13 countries. The proportion of public sector spending on health care proved to be statistically significant with the increase of income inequality indices (p<0.05). In the context of the continuous increase in health care expenditure, if benefit coverage of health security systems is not reinforced, income inequality will all the more increase due to health care expenditure. In the establishment of the policies for reinforcement of the benefit coverage, income inequality after deduction of health care expenditure should be continuously monitored.

Background & objective: The Korean government has expanded its benefit coverage to enhance patients' access to orphan drugs and cancer medicines. However, the number of new drugs whose indications were not applied to reimbursement in health insurance was increased. This study aimed to understand the perspectives of experts and various stakeholders on the introduction of a new funding program for cancer treatment and orphan drugs. Methods: We conducted email surveys comprising 19 questions, from September 9 to 26, 2016. We distributed questionnaires to members of the Pharmaceutical Benefit Appraisal Committee and Cancer Assessment Committee. We also conducted a qualitative study through group interviews with stakeholders, including pharmaceutical companies and some patient groups for diseases. Results: A total of 35 survey respondents recommended the introduction of a funding program for orphan drugs, whereas 66% recommended the launch of funding for anticancer drugs. In addition, most pharmaceutical companies and patient groups recommended the introduction of new funding programs targeting patients with cancer and rare diseases. However, some participants asserted that it would be more appropriate to modify the existing reimbursement scheme than launch new funding. Conclusion: This study concluded that introducing new funding needs a social consensus to relieve financial hardships at the patient level.

Unmanned aerial vehicles (UAVs) are a new and yet constantly developing part of forest inventory studies and vegetation-monitoring fields. Covering large areas, their extensive usage has saved time and money for researchers and conservationists to survey vegetation for various data analyses. Post-processing imaging software has improved the effectiveness of UAVs further by providing 3D models for accurate visualization of the data. We focus on determining the coniferous tree coverage to show the current advantages and disadvantages of the orthorectified 2D and 3D models obtained from the image photogrammetry software, Pix4Dmapper Pro-Non-Commercial. We also examine the methodology used for mapping the study site, additionally investigating the spread of coniferous trees. The collected images were transformed into 2D black and white binary pixel images to calculate the coverage area of coniferous trees in the study site using MATLAB. The research was able to conclude that the 3D model was effective in perceiving the tree composition in the designated site, while the orthorectified 2D map is appropriate for the clear differentiation of coniferous and deciduous trees. In its conclusion, the paper will also be able to show how UAVs could be improved for future usability.

Detection and monitoring of wildfires are essential for limiting their harmful effects on ecosystems, human lives, and property. In this research, we propose a novel method running in the Google Earth Engine platform for identifying and characterizing burnt regions using a hybrid of Sentinel-1 (C-band synthetic aperture radar) and Sentinel-2 (multispectral photography) images. The 2022 Uljin wildfire, the severest event in South Korean history, is the primary area of our investigation. Given its documented success in remote sensing and land cover categorization applications, we select the Random Forest (RF) method as our primary classifier. Next, we evaluate the performance of our model using multiple accuracy measures, including overall accuracy (OA), Kappa coefficient, and area under the curve (AUC). The proposed method shows the accuracy and resilience of wildfire identification compared to traditional methods that depend on survey data. These results have significant implications for the development of efficient and dependable wildfire monitoring systems and add to our knowledge of how machine learning and remote sensing-based approaches may be combined to improve environmental monitoring and management applications.

This study was conducted to investigate the plant community structure and to propose ecological management planning for the urban forest on Sungdongku, Joongku and Yongsanku in Seoul. Field survey was excuted October 1991 and the results were as follows. Robinia pseudoacasia community covered 61.1% and Populus x albaglandulosa covered 3.8% of survey site II and survey site was covered by the deciduous-broad leaf mixtured forest. According to the human impact and inappropriate management impact, survey area was divided into five forest community. As for the analysis of plant community structure which was classified into five forest community, the importance values, ecological diversity, number of species, number of individuals, basal area and crown coverage of the native plant community showed relatively higher than community that vegetation deterioration degree by the human impact showed seriously. In landscape forest of Mt. Daehyun, it showed problems for the planting method and the soil condition. So it was proposed to management guide, vegetation restoration and soil management through ecological management planning based on above results.

The paper presents implementation & evaluation of survey method with tilted transducer of Multi Beam Echo Sounder (MBES) to increase horizontal & vertical coverage over obstructed port environments with limited physical properties of MBES. Proposed method ($25^{\circ}$ titled transducer) have some discrepancy of bathymetric profiles between normal and tilting method, but we proved average difference is less than IHO Special Order requirements with survey data at port of Dong Ho Port, Masan, Korea. For horizontal mapping coverage of total survey area ($114,961m^2$), normal method covered 53%, $60,895m^2$ of total area but tilting method covered 75%, $5.933m^2$. It is 22% efficient than normal method with similar environments. For vertical mapping coverage of total vertical structure face ($7,421m^2$), normal method covered 14%, $1,046m^2$, proposed methods covered 60%, $4,450m^2$. And we adapt longitudal steel bar to validate MBES results, and provide calibration method with titled transducer of MBES.
