This study is about the effect chiropractic correction has on the changes in attention cathexis. A total of 20 who are currently students at Hanseo University were selected. The study measured changes in the score for the attention cathexis ability and the changes in delta wave, theta wave, alpha wave, SMR, BetaL wave, and BetaH wave of the prefrontal lobe. The changes in brainwaves of the prefrontal lobe and the score of the attention cathexis ability for the false procedure before and after the treatment did not show much difference statistically(p>.05). The chiropractic correction group showed statistically meaningful results of the decrease of delta wave, theta wave, and BetaH, and the increase of alpha wave, SMR, and BetaL on the left side(p<.05). The decrease of delta wave, theta wave, and BetaH, and the increase of alpha wave, SMR, and BetaL on the right were statistically meaningful as well(p<.05). The increase in the score of the attention cathexis ability was significant statistically as well(p<.05). The chiropractic correction affected the increase of the attention cathexis ability.

In order to observe hydrological characteristics in the Gulf of Yoeng-il, measurements of water temperature have been carried out from February to August 1983, and from August 1985 to December 1986. Surface water temperatures are closely linked to air temperature and solar-radiation for all littoral stations. Seasonal and annual variations of all horizontal stations are very similar to one another. Vertical variations of water temperatures for the stations located along the central-line of the Gulf are characteristic (and observed) as thermoclines and thermal stratification in the hottest summer-time (August). It is interesting to note that water column temperature of July and September are rather warmer than August, on account of a cold water mass coming from NE direction. For example, surface temperature in June 1982 was above 19℃, but the water below a depth of about 30m drastically drops to 4℃. It is indicative of invasion of water mass from cold current or deep sea.

Purpose: This study was aimed to specify roles of nurses from the anesthesia and recovery room by analyzing nursing activities as well as anesthesia nursing during surgery. Method: The objects were 12 RNs working in the recovery room of a university hospital located in Incheon. Self-report was performed by measuring stop-watch for five days from May 17th to May 21st in 2004. Research method was designed to record the time and frequency of the nursing activity from anesthesia and recovery room based on nurses' statement and other references for five days. The data were analyzed with descriptive statistics, ANOVA, and t-test via SPSS Win 10.0 program. Result: Nursing activities in anesthesia recovery room were classified into two different characteristics such as direct and indirect nursing activity. The activities consisted of 11 direct nursing areas and 39 nursing activities in anesthesia preparation room. The indirect nursing was classified into 8 nursing areas and 32 nursing activities. The direct nursing was classified into 12 nursing areas and 55 nursing activity. Also, the indirect nursing was classified into 7 nursing areas and 21 nursing activities in recovery room. In terms of prevalence of nursing activities in the anesthesia preparation room, observation and cooperation of anesthesia was the most prevalent activity, drug and eqipment management the second prevalent, and drug administration the third. On the other hand, in the recovery room, the most prevalent activity was vital sign checking and observation, the second most prevalent activity informative activity, and the third body temperature control. Nursing activity time was recorded according to the nursing characteristics. In the anesthesia preparation room, the direct nursing spent for 8092.20 minutes was larger than the indirect nursing spent for 7198.50 minutes. Also, in the recovery room, the direct nursing spent for 2361.16 minutes was larger than the indirect nursing spent for 1134.13 minutes. 4. Nursing activity time was compared to duty shifts. In the anesthesia preparation room, the direct nursing was more prevalent on day shift and the indirect nursing was prevalent on evening shift. However, in the recovery room, both direct and indirect nursing activities were prevalent on day shift. Conclusion: The role of anesthesia and recovery room nurses was analysed according to the time, frequency, and its characteristics.

In order to understand phytoplankton ecology in the Gulf of Yeong-il, climatic factors such as air-temperature, solar-radiation, evaporation, direction and strength of winds, and precipitation are studied from January 1982 to December 1985. Annual average of air-temperature during the four-years period is about 13.6C, ranging from 1.7C (January) to 26.5C (August). The maximum value of solarradiation is measured in spring (520MJm²in May), the minimun : in winter (62 MJm²in December, January or February), and the total annual value : about 4987MJm². Annual average of evaporation is about 1200mm (Maximum: 169 in May : Minimun: 56 in February), close to precipitation (about 1050mm). Annual average of strength of "North Winds" (350°-90°)is about 550m·sec for 156 frequences during 191 days, "West Winds" (170°-340°) : 511m·sec¹for 185 frequences during 148 days, and "South Winds" (100°-160°) about 61m·sec¹for frequences during 24 days. "N" winds is about 30% more violant than "W" winds, but both winds are influential in terms of water movements in the Gulf.

차전초(Plantago asiatica herba)는 저지대의 공터와 길가에 흔히 자생하는 다년초로서 이 식물의 종자를 차전자(Plantaginis semen)라고 부르며, 민간에서 이뇨, 소염, 천식 등의 효과로 사용되고 있다. 차전초의 성분중 Phenylpropanoid에 의한 관한 연구가 보고 되었지만 이외 성분의 소염, 진통의 약리학적인 효과에 대한 연구가 수행된 것이 없었다. 이에 본 연구는 차전초의 메탄올 추출액과 그 추출액을 다시 수층, 부탄올층, 에테르층으로 분획하여 각 분획별로 소염, 진통 효과에 대해 실험하였다. 소염효과는 카라게난 유발 족부종과 arachidonic acid(AA) 유발 귀부종에서 연구하였고 진통효과는 acetic acid 유발에 의한 writhing syndrome 대해서 실시하였는데 대조약물은 ibuprofen을 사용하였다. 카라게난 유발 족부종에서 차전초와 차전자의 메탄올 추출액은 대조군과 비교하여 족부종율에 유의성 있는 변화가 없었는데 카라게난 주사 4시간후 차전초는 용량 의존적으로 족부종을 감소시켰으나 차전자는 50, 100mg/kg에서 감소가 있었다. 차전초의 수층 분획물 100mg/kg는 카라게난 투여 3시간후 대조군의 부종율인 58.78±3.34%에 비해 부탄올 분획물의 47.43±3.28%, 에테르 분획물의 48.11±2.99%보다 43.47±2.88%의 유의성 있는 감소율을 보였다. 이는 같은 시점에서 Ibuprofen 25mg/kg의 족부종율인 40.44±3.42%와 유사함을 나타내었다. 또한 수층 분획물 50mg/kg도 역시 카라게난 투여 4시간후 대조군의54.24±2.80%에 비해 부탄올 분획물의 47.27±3.68%, 에테르 분획물의 47.36±4.67%보다 41.94±3.81%의 감소를 나타내었다. AA 유발 귀부종에서는 차전초의 메탄올 추출액이 용량의존적으로 감소를 보였으나 유의성은 없었다. 차전초의 수층 분획물 50, 100mg/kg은 대조군에 비해 부탄올, 에테르 분획물보다 감소를 보였는데 억제율은 각각 28.97%, 30.68%였다. 또한 부탄올층 50, 100mg/kg은 대조군과 비교시 귀부종을 각각 33.38±1.03%, 32.63±2.39%로 억제시켰다. Acetic acid에 의한 writhing syndrome에서 차전초의 메탄올 추출액 100mg/kg는 16.7%의 억제율을 보였고 부탄올 분획물 50, 100mg/kg 투여시 20, 23.8%의 억제율을 보였다. 차전초의 수층 분획물 25, 5Omg/kg은 21.4, 24.8%을 나타냈는데 특히 100mg/kg는 31%의 억제율을 보였다. 본 연구결과 차전초의 수층, 부탄올 분획물은 소염, 진통 효과를 나타내었고 메탄올 추출액은 Acetic acid에 의한 writhing syndrome에 효과가 있었다. 특히 분획물중 수층이 가장 효과있는 성분으로 향후 차전초의 소염, 진통 효과를 나타내는 구성성분과 기전에 대한 연구에 기초가 될 것으로 사료된다.

Yi Sang Yoon,Ungsoo Samuel Kim 대한안과학회 2021 Korean Journal of Ophthalmology Vol.35 No.6
Purpose: This study aimed to investigate the surgical outcomes of nonadjustable Harada-Ito surgery under general anesthesia. Methods: Twenty-two patients who underwent nonadjustable modified Harada-Ito surgery under general anesthesia werereviewed retrospectively. Among them, 21 out of the 22 patients who were followed up for 6 months after surgery were includedin this study. Subjective cyclotorsion (double Maddox rod test) and objective cyclotorsions (fundus photography) weremeasured. Success of the surgery was defined as follows: success (the patients do not acknowledge diplopia at any direction),partial (the patients feel diplopia at a specific direction, but they do not feel discomfort in routine life), and fail (the patientsfeel diplopia in primary gaze, hence requiring a thorough investigation). Results: The mean age of the patients (18 male and 3 female) was 56.5 years (range, 40-77 years). Based on the alternateprism cover test, the patients had 4.2 ± 3.0 prism diopters of vertical deviation. The corrected amounts of cyclotorsion basedon the double Maddox rod test and fundus photography were 14.8° ± 7.5° and 9.8° ± 7.9°, respectively, and were significantlydifferent between the two methods (p = 0.006). After the surgery, 20 out of the 21 patients (95.2%) completely recoveredfrom diplopia in the primary gaze. However, among the 20 patients, seven complained of diplopia in the secondary gaze (downgaze, four patients; head tilt gaze, three patients). The success group had a smaller preoperative subjective excyclotorsionthan the partial and fail groups (12.6° ± 2.5° and 21.0° ± 8.9°, respectively; p = 0.046). Conclusions: Nonadjustable modified Harada-Ito surgery under general anesthesia has favorable success rate, and preoperativesubjective excyclotorsion can be a prognostic factor in patients with bilateral superior oblique palsy.

ABSTRACTAn investigation of trace metal distributions in the Western Mediterranean sea was carried out during the RRS Discovery cruise (July 1993) in which a transect from the Strait of Gibraltar to the Strait of Sicily was conducted. Organically complexed dissolved trace metals and their total concentrations were measured to investigate the end-members and to predict the environmental capacity of the Mediterranean for potential toxic metals. The distribution of trace metals can be accounted for by the mixing of several end-members and by some atmospheric inputs to the surface water. For Pb and Fe the effects of the atmospheric inputs are more pronounced than for the other metals. Due to the rapid exchange of water masses, the Western Mediterranean may have the ability to assimilate the increased external inputs for some trace metals such as Cu, Cd, Ni and Zn. But the external inputs for Pb and Fe exceed the removal capacity of the Western Mediterranean and these elements may accumulate in the water column of the western basin.The C18 Sep-Pak technique and direct determination by DPASV were used to determine the amount of trace metal-organic complexes. The C18 Sep-Pak column isolates only a small fraction of trace metals except for Cu. The maximum hydrophobic fractions for the studied trace metals, except for Cd and Pb, which are not detectable, were found in the subsurface layer at all stations. This maximum may well by linked to picoplankton activity and the picoplankton, prochlorophytes may have an important role in the speciation of dissolved Cu as well as Synechococcus. These organic ligands for Cu were producted at the maximum of biological activity in the Western Mediterranean basin and seem to be accumulated at halocline level by Mediterranean hydrodynamic characteristics.However, direct determination by DPASV showed that the major part of Cu, Cd and Pb, complexed by organic materials, was not isolated by C18 Sep-Pak technique.
