Vitamin D의 주된 작용은 칼슘과 인의 흡수증가로 인한 골의 무기질화이며 vitamin D 결핍 시 에는 소아에서는 연골에 석회 침착이 안되어 구루병을 일으키고 성인에서는 골연화증 또는 골다공증이 생긴다. 또한 최근 이슈가 되고 있는 모든 암세포의 성장을 억제하고 심장병 등도 예방한다는 역학 연구 결과들이 발표되어 혈중 최적의 vitamin D농도에 관한 연구가 지속되고 있지만 일반적으로는 20~32 ng/mL의 농도가 최적의 농도라고 여겨지고 있다. 이에 우리 한국인들의 25-Hydroxy vitamin $D_3$농도를 측정하여 어느 정도의 농도를 유지하고 있는지 분석해 보고자 하였다. 2008년 2월20일부터 2009년 4월21일까지 14개월간 (재)네오딘의학연구소에 의뢰된 의료기관 종합검진 수진자 들의 혈청 25-Hydroxy vitamin $D_3$ 검사한 2,800검체를 수집하였다. 이 검체는 모두 25-Hydroxy vitamin $D_3$ ($^{125}I$ Kit: Diasorin, USA)로 검사한 후 성별, 연령별, 계절별, 지역별로 분석하여 보았다. 총 2800 검체 중 25-Hydroxy vitamin $D_3$ 평균농도는 남 20ng/mL 여 17.22 ng/mL 연령별로는 남자 10~20세 18 ng/mL, 21~30세 17 ng/mL, 31~40세 19 ng/mL, 41~50세 21 ng/mL, 51~60세는 22 ng/mL, 61~70세는 22 ng/mL, 71~80세 22 ng/mL, 81~90세는 19.9 ng/mL 여자 10~20세는 16 ng/mL, 21~30세는 15.26 ng/mL, 31~40세는 16 ng/mL, 41~50세는 17ng/mL, 51~60세는 19 ng/mL, 61~70세는 19 ng/mL, 71~80세는 19 ng/mL, 81~90세는 17 ng/mL이었다. 계절별로는 12월~5월이 15.97 ng/mL 6월~11월이 21.60 ng/mL이었다. 지역별로는 1월~4월까지의 남성을 비교해 본 결과 서울 경기 15.52ng/mL 강원도 15.33 ng/mL 충청도 18.03 ng/mL 전라도 18.68 ng/mL 경상도 18.76 ng/mL 제주도 21.23 ng/mL의 농도를 보였다. 한국인 일반인(칼슘 보충제나 종합비타민제의 복용상태는 모름)을 대상으로 25-Hydroxy vitamin $D_3$검사를 하였을때 최소치 1.98 ng/mL, 최대치 58.66 ng/mL의 분포를 보여 메뉴얼에서 제시한 Deficiency (0~5 ng/mL)에 0.3%의 상태가 있었고, Insufficiency (5~20 ng/mL) 63.3% Hypovitaminosis(20~40 ng/mL)는 36.0%인 것으로 나타났으며 Sufficiency(40~100 ng/mL)는 0.4%로 나타났다. 또한 Toxicity (>100ng/mL)상태의 대상자는 없었다. 분석결과는 실외활동을 많이 하는 남성이 여성보다 25-Hydroxy vitamin $D_3$가 높았으며 연령별로는 남 여 모두 51~80세가 가장 높았다. 또한 계절별로는 6~11월이 높았다. 지역별로는 지방이 도시보다 높았다. 최근 vitamin D의 적정농도가 골다공증과 암 예방을 할 수 있다는 연구결과가 이슈가 되고 있는 시점에 한국인의 vitamin D농도가 다른 논문에서 언급한 20~32 ng/mL에는 미치지 못한 것으로 나타났다. 물론 한국인의 참고치가 미 설정된 상태이기에 더 많은 연구와 노력이 필요하리라 생각된다. Vitamin D의 급원인 자외선이 중요한 만큼 모든 사람들이 실외활동 시간을 많이 늘려야 할 것으로 사료된다. 또한 RIA 방법이 많이 줄고 있는 이 시점에 방법이 불편하긴 하지만 vitamin D의 유용성을 높이 평가해 종합검진이나 R&D용 등으로 검사가 널리 되었으면 하는 바램이다. Purpose: The main function of vitamin D is the mineralization of the brain by increase of calcium and phosphorus, in case it is insufficient in children, lime deposition on cartilage cannot occur so it leads to rachitis, and in adults, it leads to osteomalacia or osteoporosis. It is also strongly believed in the academic world that vitamin D can restrict the growth of cancer cells and prevent heart diseases, which is also somewhat proven in epidemiological researches. While the right density of vitamin D is still being studied, 20-32 ng/mL is believed to be the most ideal density. Therefore, I wanted analyze how much density of 25-Hydroxyvitamin D3 that Koreans possess. Materials and Methods: From February 20th, 2008 to April 21st, 2009, the collection of 2800 serums, from medical examination treated subjects by Neodin Medical Institute, have been tested. The targets were tested by 25-Hydroxyvitamin D (125I Kit: Diasorin, USA), and were analyzed by dividing into many different categories (gender, age, season, region). Results: The average density of male were 20 ng/mL, female 17.08 ng/mL. Per age groups, the density of males were as follows: 10~20-18 ng/mL, 21~30-17 ng/mL, 31~40-19 ng/mL, 41~50-21 ng/mL, 51~60-22 ng/mL, 61~70-22 ng/mL, 71~80-22 ng/mL and 81~90-19.9 ng/mL. Average density of females per age groups, were as follows: 10~20-16 ng/mL, 20~30-15.26 ng/mL, 30~40-16 ng/mL, 40~50-17 ng/mL, 50~60-19 ng/mL, 60~70-19 ng/mL, 70~80-19 ng/mL, and 80~90-17 ng/mL. Per seasons, From December to May, the subjects showed the density of 15.97 ng/mL, while from June to November, it showed 21.60 ng/mL. On density of males from January to April regionally, Seoul+Gyeonggi-Do-15.52 ng/mL, Gangwon-Do-15.33 ng/mL, Choongchung-Do-18.03 ng/mL, Jeonla-Do-18.68 ng/mL, Gyungsang-Do-18.76 ng/mL and Cheju Do-21.23 ng/mL. Conclusions: The vitamin D of Koreans is has been insufficient compared to the suggested amount. Ultraviolet rays, which is the main source of vitamin D is critical, therefore it is suggested that more outdoor activities can definitely help.

Throughout this research course, we have analyzed the financial situation of more than 2,700 companies using credit evaluation disclosures from 2017 to 2019. The population was gathered based on the certification of Ppuri companies and Ppuri Expertise companies through the Korea National Ppuri Industry Center, accompanied by the NICE credit evaluation index. For the first time in Korea, we wanted to look at growth, profitability, and stability through financial analysis of the Ppuri industry. Through an indepth analysis, we identified operating income (rate), net income (rate), asset size, and debt ratio, along with three years of Ppuri company workers and total sales fluctuations, and looked at the financial structure per capita. In addition, financial status per person was compared by dividing Ppuri companies into six groups by employee size. Groups were 10 or fewer people, 11 to 20 people, 21 to 50 people, 51 to 200 people, 201-300 people, and 300 or more people; single individual companies were excluded for research convenience. Overall, the financial situation of Ppuri companies was judged to be in a very bad downturn, and financial indicators deteriorated over the course of the three years of investigation. In particular, the smaller the number of employees, the greater the financial fluctuations were and the worse the situations were. Among Ppuri companies, the casting industry, which is the technical starting point for the value chain of the industry, was found to also be in a very bad state, with continued workforce declines, total assets and sales reductions at severe levels, and operating income (rate) and net income (rate) also very poor. This is why we need a suitable and feasible policy direction, something that is difficult but must be allowed to develop.

This paper examines differences of the participants’ Negative Polarity Item(NPI) responses and discovers the reason for the differences. Sixty children aged four to six took part in the experiment for this study. In the result, the participants produced more NPIs in object position than in subject position. The K5 group produced fewer NPIs among the three groups during the experiment. Unlike English any -type NPIs, other NPIs such as hanato and amwusalam-to can be used instead of Korean NPIs amwuto . Compared to the study done by Kim (2016), the Korean children produced much more NPIs both in subject and object positions. Another finding here is that the difference is not statistically significant both in subject and object positions unlike Kim’s study. In summary, the responses manifested no subject/object asymmetry for NPIs in Korean.

(4)내전압시험법의 동향 - 상용주파에 의한 내전압시험은 수트리 열화정도와 잔존파괴성능의 관계 및 수트리 진전속도등이 아직 명확해지지 않았지만, 전력케이블의 열화진단에 유용할 것으로 생각되며, 케이블 길이 가 긴 경우에는 전원용량 때문에 시험설비가 대형화되어지는 문제가 있다. 최근에는 교류내전압 시험과 동등한 능력을 갖고 건전케이블에 미치는 영향이 작고 시험설비가 작아질 수 있는 이점을 가진 감쇠진동파법, 초저주파법 등이 검토되고 있다.(중략)

This study investigated the development and core mechanism of subitizing in children and adults as well as provides related theoretical and practical discussions. This study was conducted to determine if subitizing changed with the age of participants and if there were differences in subitizing according to the spacing, color, and shape of the stimuli. The subitizing task set (including forty main trials) was prepared. Forty-five children (fifteen each in groups of 3, 4, and 5-year-olds) and fifteen adults were recruited to perform the subitizing tasks. The results demonstrated that the subitizing speed and accuracy of children improved abruptly between age 3 and age 4. Furthermore, there were significant differences in children's subitizing speed according to the spacing and color of the objects. The children's response time decreased when the objects were fully apart or were of diverse colors. In addition, there were partial significant differences in the subitizing speed of children related to the shape of the objects. The subitizing speed of children decreased in a condition (subitizing 5 objects of diverse colors in fixed spacing) when the shapes of the objects were diverse. The subitizing speed of adults only differed according to the space of the objects. The results demonstrate the development of subitizing in early childhood along with the presence of object individuation processing stages underlying subitizing. This study also provides practical information and suggestions for educational curricula that can strengthen the competency of children in systematic and diverse activities.
