In order to secure clinical evidence for the treatment of cold accumulation (CA), this study reviewed and analyzed 91 records of literature and related records. To perform a classical literature search, the Oriental Medicine Classic databases and the Uibujeonrok electronic data were searched. Books on Immunopharmacopuncture (IP) were also reviewed. A common etiology for CA was attributed to the abdomen, while the detailed sites of the abdomen differed. In IP, CA had a more comprehensive list of symptoms of physiological and pathological significance. As for the treatment of CA, typically, herbal medicine was used until the end of the Korean Empire period, and moxibustion treatment on CV4, CV6, CV-12, ST36, EX-B4, and conduction exercise therapy were also reported. Since 1965, acupuncture needle-based invasive treatment such as acupuncture for CA, and IP have been described in IP theory. Consequently, the treatment of CA (as described in the IP theory), was considered to be a more advanced method of treatment compared with the existing classical treatment methods.

동계 동중국대륙의 연안수가 발달하여 쿠로시오 난류의 경계역으로 확장된 후 주변의 북상 난류역에 의해 포획됨으로써, 고립되는 현상이 1999년 및 2003년 NOAA 위성영상에 포착되었다. 1999년의 경우 냉핵 와동류(cold core eddy)는 약 2개불간 존재하였고 (5월초~6월 하순), cold core의 중심 수온은 15~2$0^{\circ}C$로 주변보다 2~3$^{\circ}C$ 낮게 나타났다. NOAA 위성수온 영상에 포착된 냉핵 와동류의 주변 가장자리 해역에서 SeaWiFS 위성자료로부터 추정된 클로로필 $\alpha$ 분포는 4.0~6.0 mg/m$^3$으로 냉핵 와동류 중심해역의 농도 1.0~3.0 mg/m$^3$ 보다 2배정도 높게 나타났다. 2003년 경우 2월중순에 냉핵 와동류 중심수온은 9~1$0^{\circ}C$였다. 와동류의 크기는 직경 150km 정도였으며, 냉핵 와동류의 수평 분포양상은 50m 등수심 분포와 유사하게 나타났다. 이어도(Socotra Rock) 해역을 중심으로 동계-춘계에 발생되는 냉핵 와동류의 형성 메카니즘은 중국대륙 연안수와 쿠로시오 난류가 만나는 경계역에서 수괴간의 힘의 균형, 계절풍 조건 및 해저 지형 분포와 밀접한 관계성이 있는 것으로 나타났다.

We examined the community structure of fish off the coast of Jindo Island in response to a cold water appearance in the southwestern sea of Korea each August between 2013–2015. Using a gape net with wings, we collected 31 taxa during the study period, wherein the most dominant species was Engraulis japonicus. Collichthys lucidus and Neosalanx andersoni, which are mainly distributed in the western sea of Korea, increased in abundance and were dominant in August 2013, possibly due to the apparent intrusion of cold water (< 19°C) from offshore into the coastal waters of Jindo Island. Meanwhile, Scomberomorus niphonius and Sardinella zunasi, which are known as warmwater migratory species, increased in abundance and were dominant in August 2015, likely influenced by the warmer water (> 20°C) at the coast, which resulted in a noticeable lessening of the cold water in the study area. However, no significant differences were observed in fish community structure in the month of August between 2013–1015. This implies that the small-scale spatial and temporal variations in the cold water had limited effects on the fish community structure, even though the abundances of several dominant species varied in the coastal waters.

본 연구에서는 하계 한국 남동해 간절곶 주변해역의 냉수대 구조와 변동을 CTD 관측과 수층별 수온 장기 연속 모니터링 자료를 이용하여 분석하였다. 냉수대의 표층수온은 냉수기 이전과 $-12^{\circ}C$의 차이를 보였으며 해저지형 효과로 간절곶에서 냉수대 세력이 가장 컸다. 남북해역 간 등온선의 시계열분포에 간절곶을 경계로 공간변화가 발생해 간절곶 주변 해저지형이 언덕(hill)역할을 하고 있음이 추정되었다. 냉수대는 해안에 평행한 풍속이 양(+)의 값일 때 출현하는 연안용승반응을 나타냈고, 수온의 감소와 상승은 풍향이 바뀐 후 하루 이내에 반응하였다. 간절곶 주변은 얕은 수심 주위에서 발생하는 와류효과가 결합하여 바람에 의한 용승효과가 강화되었다. 수온변화는 2~6일 주기의 바람변동에 민감하였으며, 수온감소는 12~36시간의 위상차를 나타냈다. 냉수대가 출현한 7월은 2~3일 주기, 8월은 3~8일 주기에서 바람-수온변화의 상관성이 컸다.

The purpose of this study is to examine the effect of the improved cold tolerance resulting from cool clothing in winter on heat tolerance in summer. Ten healthy women were divided into two groups, cold group(C group) (n=5) and warm group(W group) (n=5) . In the previous study, C group was proved that their cold acclimatization was achieved through wearing cool clothing from September to February of the following year, while Wgroup was not proved because of wearing warm clothing during same period. After February, no more clothing training was continued in two groups. To determine the heat tolerance, both groups were exposed from a thermoneutral environment(25$\pm$1$^{\circ}C$, 50$\pm$5% R.H.) to a hot environment (35$\pm$1$^{\circ}C$, 50$\pm$5% R.H.) before and after clothing training, respectively September in 1994 and truly in 1995. Rectal temperature, skin temperatures, thermal sensation and comfort were measured every 10 min., and Os uptake was measured at 10, 45, 85 min. after entering the chamber for 5 min. Body weight was measured before and after the experiment and amount of local sweat was measured during the 90 min long experiment. The results are as follows: Rectal temperatures in 35'c environment of C group were increased after training when compared with before clothing, while those of W group were not changed. But the changes of rectal temperature and heat production during 90 min in hot environment were almost the same in two groups after training. And mean skin temperatures, the changes of mean skin temperatures during 90 min in hot environment, total sweat amount and local sweat amount after training were also the same in two groups. From these results, it might be supposed that the heat loss of two groups were the same but the heat production, especially heat production during rest in C group was higher than in Wgroup. This fact suggests that the increase of rest heat production from cold acclimatization in winter is maintained to summer of the following year. And mild cold acclimatization coming from westing cool clothing does not have a negative effect on heat tolerance.

The food cold chain refers to a technology and distribution supply chain applied to maintain a constant temperature suitable for the product from production (harvest) to delivery to consumers. In particular, in Korea, the insulation material used in the food cold chain is mostly EPS (Expanded Polystyrene), which is used as a transport container for various food cold chains. However, according to the government's eco-friendly policy, companies charge environmental contributions to the use of EPS, but due to its low price and convenience of handling, it is still used as a container for delivering food. In this study, in order to measure the domestic delivery environment of general refrigerated foods, changes in impact, temperature, and humidity during transport of the EPS packaging system containing foods and ice pack refrigerants were measured. As a result, there were 2?3 sections in which a high impact force of 40 G or more was generated during transport. This can cause damage to the product and EPS container. The difference in temperature and humidity changes by parcel transport routes is more than 30%, so it is necessary to present accurate standards for the domestic cold chain distribution environment. As a result of microbial experiments. the transportation period had a dominant effect on the increase in total viable count and E. coli count.

Objectives : This study aimed to investigate the relationship between cold feet and sleep quality using polysomnography (PSG) and Pittsburgh Sleep Quality Index (PSQI). Methods : We divided 11 adults (6 females, 5 males) with Insomnia Severity Index score below 21 into cold feet (CF) and a non-cold feet (NCF) group based on the median feet temperature (Taichong, LR3). PSG and PSQI were administered to assess sleep characteristics and subjective sleep quality. Results : CF group exhibited significantly lower time in bed, sleep period time, and total sleep time compared to NCF group. While there were no significant group differences in sleep latency, wakefulness after sleep onset, or total arousal index, NCF group had significantly lower minimum oxygen saturation and apnea-hypopnea index in REM (rapid eye movement) sleep compared to CF group. Although the PSQI score and the proportion of poor sleepers were both higher in the CF group (7.40 and 80%) compared to the NCF group (5.50 and 50%), these differences did not reach statistical significance. Conclusions : This study showed that foot temperature affects sleep characteristics and suggests the need to utilize PSG in sleep research in Korean medicine.

This paper is to investigate the change of the period of hot weather concrete with elapse of age based on climate data. Climate data for 30 years and 5 years are used respectively. Determination of the period of hot weather concreting on architectural execution in Korea according to the specifications of AIJ, KSCE, and ACI are discussed. According to the research, the period of hot weather concreting with each specification in most regions lasts over 35 days. Compared with the period of cold weather concreting in hillside and inland area, coastal areas have shorter period in the same latitude. The period of hot weather concreting tends to decrease with high latitude. As expected, with the elapse of age, the period of hot weather concrete exhibited to decrease, especially, big city like Seoul, Busan etc had remarkably increased period by as much as a week. This is due to the global warming and industrialization effect with the elapse of age.
