Purpose: A purpose of this study was to identify the effects of cold water gargling on thirst, oral cavity condition and sore throat in orthopedics surgery patients who underwent general anesthesia. Methods: Pretest-posttest non-synchronized design with a nonequivalent control group was used. A total of 52 participants were conveniently selected and assigned to each group. The experimental group gargled hourly with cold water for 8 hours after operation. The control group received wet gauze as needed. We compared the thirst, oral cavity condition and sore throat at 0, 2, 4 and 8 hours after operation. Results: The score of thirst and oral cavity condition was lower in the experimental group than in the control group. However, there was no significant differences in the levels of sore throat between the experimental and control group. Conclusion: These findings suggest that cold water gargling can be a useful nursing intervention for alleviating thirst and improving oral condition for patients with orthopedic surgery after general anesthesia.

경상북도 구룡포 해역에서 하계 냉수 발생 특성과 어류 폐사를 유발하는 냉수대 강도를 파악하고자 2007년 8~11월 멍게양식장에 수온로거를 설치하여 수층별 수온을 측정하였으며, 2015년과 2016년은 국립수산과학원 실시간어장정보시스템의 표층수온 자료를 이용하였다. 동해 남부해역의 냉수대 발생 원리와 부합하게 남~남서풍이 강하게 불 때 용승으로 표층수온이 급격히 하강하였으며(2007년 8월 하순, 9월 20~22일, 2015년 7월 13~15일), 반대로 북~북동풍이 우세할 때 저층수온이 급상승하는(2007년 9월 5~7일, 9월 16~18일) 것으로 나타났다. 그 외에도 7~8월 구룡포 해역에 나타나는 약한 강도의 표층수온의 하강과 상승은 바람 방향과 밀접한 관계가 있는 것으로 나타났다. 구룡포 해역에서 최대풍속이 5 m/s 이상인 남~남서풍이 최소 이틀 이상 유지되면 표층수온이 약 $10^{\circ}C$ 이하로 하강하는 강한 냉수대가 발생하고 이로 인해 어류 폐사가 발생하는 것으로 파악되었다. 이를 바탕으로 포항기상대의 최대풍속과 최대풍속 풍향을 이용하여 냉수발생지수(Cold Water Index)를 정의하고 계산한 결과, $CWI_{2d}$(CWI 2일 평균)가 100 이상일 때 어류 폐사가 주로 발생하였으며, $CWI_{4d}$(CWI 4일 평균)는 7~8월 구룡포 표층수온과 높은 음의 상관성을 나타내었다($R^2=0.5$). 2007년 10월 30 m 수층의 수온 일변화($7{\sim}23^{\circ}C$)는 조석변화와 일치하는 주기와 스펙트럼을 보였으며, 이는 북한한류수 영향인 것으로 파악된다. 이와 같이 조석과 북한한류수로 인한 일변화가 어류 가 두리가 설치된 수심에도 영향을 미친다면 어업 피해로 이어질 수 있으므로 정밀한 조사가 필요할 것으로 생각된다.

Purpose : This study is to examine the effects of Hwaganjeon water extract(HGJ) on immobilization-stress or cold-stress in BALB/C mice. Methods : We have Hwaganjeon water extract(HGJ) by freeze-dryer & melt it by a saline solution. We feed HGJ 500mg/Kg to 5mice, and add immobilization-stress by putting mice in plastic cylinder 10 hours, and add cold-stress by putting mice in $4^{\circ}C$ cold room 6 hours. Results : 1. HGJ decreased the serum level of histamine and corticosterone increased by immobilization-stress or cold-stress. HGJ inhibited the release of histamine from mast cells at the concentration of 1 mg/ml. 2. HGJ did not affect the cell viability of thymocytes decreased by immobilization-stress or cold-stress, but increased the cell viability of splenocytes decreased by immobilization-stress or cold-stress. 3. HGJ decreased the population of splenic $CD4^{+}$ and $CD8^{+}$cells increased by immobolization-stress or cold-stress. 4. HGJ enhanced the production of ${\gamma}$-interferon(IFN) and interleukin(IL)-2 decreased by immobilization-stress or cold-stress. Conclusion : These results indicate that HGJ may be useful for the prevention and treatment of stress via suppression of serum histamine and corticosterone level and enhancement of immune response.

Most scyphomedusae jellyfishes recorded in Korean waters are temperate and subtropical species. In the present study, two cold-water jellyfishes from Korean waters are first described. Scyphomedusae were collected from the coasts of Gangneung and Ulsan of the East Sea, and Boryeong, and the eastern area of the Yellow Sea from June 2006 to May 2015. Scyphomedusae collected in Ulsan and Gangneung were identified morphologically as Aurelia limbata Brandt, 1835. Their umbrella was 250-500 mm in width and 30-50 mm in height; the exumbrella was white and the subumbrella was dark brown in color. The vascular system was complex with anastomosed branches. Individuals of this species lived at about 6.6-9.9℃ and 30-50 m depth in Korean waters. Scyphomedusae collected from the center of the Yellow Sea and from Boryeong were identified as Parumbrosa polylobata Kishinouye, 1910. Their umbrella was disc-shaped, 80-200 mm in width and 20-40 mm in height. Its milky white gonads could be seen through the transparent exumbrella. The stomach cavity was round and flat with four interradial cavities connected by subgenital cavities, and the four oral arms were bifurcated and spear-head shaped. Individuals were found at about 6.4-10.0℃ and 40-90 m depth in Korean waters. The identities of both species were confirmed by molecular analysis using nuclear ribosomal DNA sequences.

Objective: This study aimed to determine the effect of intermittent feeding and cold water on performance and carcass traits in broiler chickens between 4 to 6 wk of age exposed to daily high temperature. Methods: Broilers were assigned to four treatment groups according to a 2×2 factorial design between 22 to 42 d of age (80 broilers per treatment, 4 replications). Broilers were divided into two main groups as feeding type (ad-libitum [AL] and intermittent [IF] for 6 h daily) and sub-groups as water temperature (normal [NW], 24.9℃ and cold [CW], 16.4℃). Heat treatment was applied between 11.00 to 17.00 h daily between 22 to 42 d of age. Results: Live weight at 6th wk was not affected by feeding type and water temperature, but the live weight was significantly higher in IF chickens at the 5th wk (p<0.05). Average weekly gain of IF broiler chickens were higher compared to AL group at 4, 5, and 6 wk of age (p< 0.05). Although feeding type did not affect feed intake in 4 and 5th wk, feed intake was higher in IF chickens at 6th wk (p<0.01). In addition, feeding type and water temperature did not affect feed conversion ratio and interactions were not significant (p>0.05). Water temperature had no significant effect on heart, liver, gizzard, and abdominal fat percentages (p>0.05). Conclusion: It is concluded that IF increased the average weekly gain in chickens reared under daily heat stress for 6 h between 22 to 42 d of age. IF in hot environmental conditions slightly increased performance without adversely affecting health, welfare, and physiological traits, whereas CW implementation had no significant effect on performance. It can also be said that IF suppresses a sudden increase in body temperature depending on age and live weight.

1982년과 1983년 여름 한국 남동 해안부근에서 관측된 냉수를 수온, 염분, 해면, 바람 및 인공위성 영상의 자료를 이용하여 연구하였다. 3층구조의 해양을 보이는 여름철에 수일 동안 지속되는 단속적인 남서풍에 의해 완벽한(full) 용승현상이 나타난다. 용승기간 동안에 고온의 표층수는 외해로 이동하였고, 저온의 중층수가 해표면으로 노출하였으며, 해면은 하강되었으나 표층의 균형(equilibrium) 깊이는 변화되지 않았었다. 관측결과는 해표면의 냉수가 중층으로부터 기원되고 강한 전선은 계절 수온약층이 해표면에 상승된 결과임을 보인다. 해표면 전선위치와 바람입력사이의 상관관계 파악을 위해 Csanady(1982)의 모델을 rigid lid 근사조건에서 해를 구하였다. 그 결과는 전선의 위치가 바람입력 및 한국 남동 해안부근의 해양구조에 의해 결정될 수 있음을 보이고 있다. 여름철 냉수는 $10m^2/sec$ 크기 정도인 최소 바람역적보다 큰 바람이 작용될 경우에만 해표면에 나타날 수 있다.

Oceanographic observation and qualitative analysis for deep ocean water in the East Sea were carried out from January 2003 to January 2004, in order to understand the characteristics of deep sea water in the East Sea. Temporal and spatial variation of water masses were discussed from survey of the study area including the coastal sea of Kwangwon province in where the polar front mixing cold and warm water masses were formed. On the basis of the vertical profiles of temperature, salinity and dissolved oxygen, water masses in the study area were divided into 5 major groups; (1) Low Saline Surface Water (LSSW) (2) Tsushima Surface water (TSW) (3) Tsushima Middle Water (TMW) (4) North Korea Cold Water (NKCW) and (5) East Sea Proper Water (ESPW). In winter, surface water in coastal sea of Kwangwaan Kosung region were dominated by North Korean Cold Water (NKCW). As Tsushima warm current were enforced in summer, various water masses were vertically emerged in study area, in order of TSW, TMW, NKCW and ESPW. It is highly possible that the LSSW which occurred at surface water of september is originated from influx of fresh water due to the seasonal rainy spell. Nevertheless water masses existed within surface water were seasonally varied, water quality characteristics of East Sea Proper Water (ESPW) under 300 m did not changed all the seasons of the year.

Purpose: This study was aimed to compare the effect between wet gauze with cold normal saline and wet gauze with cold water on thirst, oral cavity condition, and saliva pH among postoperative patients. Methods: This study was a quasi-experimental study with 56 participants. The experimental group received wet gauze with cold normal saline, and control group received wet gauze with cold water for three times at 15 minute intervals. Data were collected using visual analog scale for thirst, oral assessment guide for oral cavity condition and acidity tape for saliva pH. Measurement were made before applying the gauze and at 15min, 30min, and 45min after applying gauze. Data were analyzed using repeated measured ANOVA. Results: Thirst, oral cavity condition, and saliva pH improved in both groups with increasing number of gauze application. Thirst for the experimental group improved more than for the control group (F=4.29, p=.009), oral cavity condition except saliva, and saliva pH were not significantly different between the groups. Conclusion: This study results indicated that nurses can apply wet gauze with cold normal saline to reduce thirst and saliva acidity, and to improve the oral cavity condition for postoperative patients.
