Objectives : The objectives of this study were to estimate the continuity of care for all Koreans with diabetes and to identify factors affecting the continuity of care. Methods : We obtained National Health Insurance claims data for patients with diabetes who visited health-care providers during the year 2004. A total of 1,498,327 patients were included as study subjects. Most Frequent Provider Continuity (MFPC) and Modified, Modified Continuity Index (MMCI) were used as indexes of continuity of care. A multiple linear regression analysis was used to identify factors affecting continuity of care. Results : The average continuity of care in the entire population of 1,498,327 patients was $0.89{\pm}0.17$ as calculated by MFPC and $0.92{\pm}0.16$ by MMCI. In a multiple linear regression analysis, both MFPC and MMCI were lower for females than males, disabled than non-disabled, Medicaid beneficiaries than health insurance beneficiaries, patients with low monthly insurance contributions, patients in rural residential areas, and patients whose most frequently visited provider is the hospital. Conclusions : The continuity of care for patients with diabetes is high in Korea. However, women, the disabled and people of low socio-economic status have relatively low continuity of care. Therefore, our first priority is to promote a diabetes management program for these patients.

This study was conducted to identify the needs of introducing new medical specialties in oriental medicine. Three stakeholders in introducing new oriental medical specialties are oriental medical doctors, policy makers and medical consumers. Of the three, this study intended to focus on opinions of oriental medical doctors. About 1,150 self-administered questionaries were sent to the potential respondents, 320 specialists, 250 interns & residents and 580 private oriental medicine practitioners, and 480 doctors responded. The study revealed that 62% of respondents showed negative attitudes towards the introduction of new oriental medicine specialties. The private oriental medical practitioners were more likely not in favor of adding new medical boardmanship. The reasons of objection were as follows : First, it is more important to enrich the existing oriental medical boardmanship (70%). Second, the newly established specialties are most likely to be weakened(15%). The study revealed that the first and most likely specialties to be introduced was Chuna(18%), subspecialization of oriental internal medicine (15.8%), the next oriental family medicine (15.1%) and so on. And the second specialties to be desired most by the respondents were (1) cooperative medicine between the westem and oriental medicine (28%), (2) oriental preventive medicine (17.4%) and (3) oriental family medicine (16.8%). Caution must be exercised in introducing new oriental medicine specialties. The failures of western medicine in the operation of its specialist production should carefully by examined here.

Big data in the form of Internet searches can provide simple and effective analysis and forecasting compared with previous traditional polls. In particular, Google, which has the largest number of users worldwide, provides a dynamic website called Google Trend, which investigates searched keywords and provides trends in the region. This study analyzed the results of the 17th-19th Korean presidential elections using Google Trend and showed that the winners of each presidential election can be predicted. In addition, we found a remarkable correlation between the difference in the average Google Trend value and the difference in the voting rate during a given election period. The recent 20th presidential election was also analyzed. 인터넷 검색 형태의 빅 데이터는 이전의 전통적인 여론조사와 다르게, 매우 간단하고 효과적인 분석 및 예측을 제공할 수 있다. 특히 전 세계적으로 가장 사용자가 많은 구글은 구글 트렌드라는 동적 웹 사이트를 제공함으로써, 검색된 키워드를 조사하고 그 지역의 트렌드를 제공한다. 이 연구에서는 구글 트렌드를 사용하여, 앞선 한국의 17대-19대 한국 대통령선거(대선)의 결과를 분석하였고, 각 대선의 승자를 예측할 수 있음을 보여주었다. 또한 주어진 선거기간 동안, 대선 후보 간 평균 구글 트렌드 값의 차이와 실제 후보 간 득표율 차이에 유의미한 상관관계가 존재함을 입증하였으며, 최근 치러진 2022년 20대 대선을 분석하였다.

Objectives : A few culture-confirmed cases of S. sonnei have been notified from Korean hospitals. The source of epidemic can't be firmly determined in such cases because of the rarity of this illness in the local communities and the timing of the outbreaks. The objective of this study is to estimate the source of epidemic by investigating the patients' lifestyles. Methods : Alibi verification was used to access the presumed source of the epidemic. PCR (Polymerase Chain Reaction) was used to rapidly detect the genes of Shigella in water specimens. Results : The common lifestyle trait among the Shigella infected patients was connected with Mt. Martyr in J city, Korea. The first patient's son had gone on a pilgrimage to Mt. Martyr with 41 friends and he had only eaten rice cakes on April 5th; the second patients had visited Mt. Martyr with their mother for a picnic on April 12th; the third patient had visited Mt. Martyr with 22 friends for a pilgrimage and the patient had only drunk holy water on April 13th. Therefore, the holy water of Mt. Martyr was reckoned to be the source of the epidemic. PCR detected the genes of Shigella two days before the S. sonnei was confirmed. Conclusion : The patients' lifestyles for 7 days before the onset of symptoms should be determined in terms of time, place and contacted people to find the source of infection when cases with food poisoning are seen in the hospital setting.

The purpose of this study was to find out the various opinions of Oriental Medical Doctors to give the recommendations for making the proper policy of the supply and demand of Oriental Medical specialist. This study was desinged of 480 doctors who answered about questions that is composed of 105 Oriental medical specialist, 227 Apprentice doctor and 148 Oriental Medical doctors. On the assumption that there are many different situations and visions about the Oriental medical specialty system, we wanted to know about the each situations and visions about oriental specialty system. Generally, as one grows older, they adapted high proportion about the propriate number of specialist. About this difference from each generations, we can explain that young doctors more worry about the supply of specialist. As well each achievement, the more higher achievement, the more higher proportions of specialist is adapted. Answers about the number of present specialist, the more aging the more negative response about the number of present, number of specialist, this is because of the proprotions who wanted to be a specialist in open doctors. About the property of the number of specialist, there are many different views in each other groups. Anyway it is important that hearing the opinion of each Oriental Medical Doctors for the better Oriental Medical System.

개방형 사무실에서 소음과 스피치 프라이버시 문제는 꾸준히 제기되어 왔다. 이러한 개방형 사무실의 문제점을해결하기 위한 마스킹 음원에 대한 연구가 필요하다. 따라서 본 연구에서는 청취 실험을 통하여, 쾌적한 물소리를 마스킹음원으로 제안하고자 한다. 먼저 다양한 소음 레벨에 대하여 음환경 쾌적도와 스피치 프라이버시를 고려한 최적 물소리레벨에 대하여 고찰하고자 한다. 이후 최적 레벨의 물소리 도입이 업무효율성에 미치는 영향을 검정하고자 한다. 청취실험에서 사용된 사무실 소음은 실제 개방형 사무실에서 바이노럴 마이크를 활용해 녹음하였고, 헤드폰을 통해 피험자들에게 제시하였다. 청취실험 음원은 각각 3개의 등가 배경소음레벨(55 dBA, 60 dBA, 65 dBA)과 5개의 신호대잡음비[Signal to noise ratio(SNR) –10 dB, –5 dB, 0 dB, +5 dB, +10 dB]의 조합로 구성하였고, 각 음원에 대한 주관평가로전체적인 음환경 쾌적도(Overall Soundscape Quality, OSQ)와 듣기 어려운 정도(Listening Difficulty, LD)를 평가하였다. 평가 결과 배경음 보다 물소리가 커질수록 LD는 증가하였지만 OSQ는 감소하였다. 특히 물소리가 사무실 소음 보다 클경우 도입 전보다 OSQ가 감소하였다. 따라서 OSQ와 LD를 고려하였을 때 소음레벨별 최적 SNR은 모든 소음레벨에 대하여, –5 dB로 나타났다. 이후 업무 효율성을 평가하기 위하여, 최적 레벨의 물소리 도입 전후에 인지능력(Cognitive performance)을 평가하였다. 평가 결과 최적 레벨의 물소리를 도입할 경우, 배경소음이 55 dBA에서는 인지능력평가 결과가 물소리 도입 전에 비해 감소하는 것으로 나타났으나, 60 dBA와 65 dBA에서는 증가하는 것으로 나타났다. This study aims to investigate the preferred sound level of water sound for various levels of open-plan-office noise regarding soundscape quality and speech privacy. And assessment of the work efficiency of the water sound. For the laboratory experiment, office noise was recorded using a binaural microphone in a real open-plan office. For the assessment of the soundscape quality and speech privacy, Overall Soundscape Quality (OSQ) and Listening Difficulty (LD) were evaluated under three different sound levels (55 dBA, 60 dBA, and 65 dBA) and five different signal-to-noise ratios (SNR –10 dB, –5 dB, 0 dB, +5 dB, and +10 dB). After the evaluation, the preferred SNR was proposed according to OSQ and LD. For the assessment of to work efficiency of water sound, this study evaluated the cognitive performance of both of the condition noise only and combine the water sound with office noise. The results showed that LD increased as the water sound level increased, but OSQ decreased. When the water sound level was more than the office noise level, the OSQ decreased from noise only. Therefore, considering OSQ and LD, the preferred SNR of water sound was –5 dB for all noise levels. At the preferred level of water sound, the cognitive performance results were shown to decrease at 55 dBA compared to noise only, but at 60 dBA and 65 dBA combine the water sound results were increased than the noise only.
