Purpose: The purpose of this study was to identify the job of emergency room (ER) nurses working in small and medium sized hospitals and to explore factors affecting their job. Methods: The survey data were collected between January 2014 and May 2014 and participants were 159 nurses working in Seoul, Kyunggi, Incheon, and Chungnam in hospitals of less than 500 beds. Results: The score for nurses job was 2.12/4.0, and emergency treatment (1.87/4.0) followed basic nursing (3.51/4.0) and counseling (2.32/4.0). The nursing job was significantly different depending on the age, education level, position, resident doctor(emergency medicine specialty or other) and grade of ER (regional ER or local ER). In the multiple regression, education level (${\beta}=.18$), position (${\beta}=.24$), hospital size (${\beta}=.20$), and grade of ER (${\beta}=.21$) explained 17.0% of variance in ER nurses' job in small and medium sized hospitals. Conclusion: The findings indicate that ER nurses in vulnerable areas do more nursing practice including emergency treatment as well as the usual independent nursing practice. Accordingly, a systematic assignment of nursing professionals is needed to reduce loading of ER nurses in small and medium sized hospitals.

Purpose: The study aimed to identify the effects of a newborn care education program on newborn care confidence and behavioral accuracy of primiparas in a postpartum care center. Method: This was a quasi-experimental study with a non-equivalent control group non-synchronized design. Subjects were 29 primiparas selected from a postpartum care center in D and P hospitals in Ulsan. The intervention was a newborn care education program which was composed of education with a booklet, demonstration, watching a video, and verbal encouragement. The outcome variables were newborn care confidence and behavioral accuracy. Data was collected from Feb. 1 to Mar 22 in 2005 with self-administered questionnaires and observation by researchers. Data was analyzed using the $X^2-test$, Fisher's exact test, t-test and ANCOVA. Result: The experimental group showed significantly higher score changes between the pre-test and post-test in confidence and behavioral accuracy than the control group. Conclusion: The newborn care education program showed positive effects on newborn care confidence and behavioral accuracy of primiparas in a postpartum care center. Therefore, we recommend that this program should be applied in postpartum care centers.

This study proposed a simple estimation method for irrigation return flow from paddy fields using the water balance model. The merit of this method is applicability to other paddy fields irrigated from agricultural reservoirs due to the simplicity compared with the previous monitoring based estimation method. It was assumed that the unused amount of irrigation water was the return flow which included the quick and delayed return flows. The amount of irrigation supply from a reservoir was estimated from the reservoir water balance with the storage rate and runoff model. It was also assumed that the infiltration was the main source of the delayed return flow and that the other delayed return flow was neglected. In this study, the amount of reservoir inflow and water demand from paddy field are calculated on a daily basis, and irrigation supply was calculated on 10-day basis, taking into account the uncertainty of the model and the reliability of the data. The regression rate was calculated on a yearly basis, and yearly data was computed by accumulating daily and 10-day data, considering that the recirculating water circulation cycle was relatively long. The proposed method was applied to the paddy blocks of the Jamhong and Seosan agricultural reservoirs and the results were acceptable.

The purpose of this study was to detect QTL for carcass quality on bovine chromosome (BTA) 6 using a high density SNP map in a Hanwoo population. The data set comprised 45 sires and their 427 Hanwoo steers that were born between spring of 2005 and fall of 2007. The steers that were used for progeny testing in the Hanwoo Improvement Center in Seosan, Korea, were genotyped with the 2,535SNPs on BTA6 that were embedded in the Illumina bovine SNP 50K chip. Four different linkage disequilibrium (LD) mapping models were applied to detect significant SNPs for carcass quality traits; the fixed model with a single marker, the random model with a single marker, the random model with haplotype effects using two adjacent markers, and the random model at hidden state. A total of twelve QTL were detected, for which four, one, three and four SNPs were detected on BTA6 under the respective models (p<0.001). Among the detected QTL, four, two, five and one QTL were associated with carcass weight, backfat thickness, longissimus dorsi muscle area, and marbling score, respectively (p<0.001). Our results suggest that the use of multiple LD mapping approaches may be beneficial in increasing power to detect QTL given a limited sample size and magnitude of QTL effect.

Purpose: The purpose of this study was to examine the meaning and essence of suicide for elderly people who had previously attempted suicide as an older person. Methods: Giorgi's descriptive phenomenology was used for analysis. The researchers carried out in-depth interviews, recordings and memos individually with four elders. The elders were individuals who had attempted suicide sometime in the past 5 yr. They were interviewed from 5 to 10 times using open-ended questions and a semi-structural format. Demographic data were also collected. Results: The meaning of suicide before a suicide attempt in older people had four core components: conflict with family, powerlessness and despair in their life with a drop in self-esteem, using internal and external resources to resolve their troubles and awareness of imminent crisis. Conclusion: These results of this study will increase understanding of suicide in older people by defining their subjective experience of suicide attempts and applying grounded data in the development of programs that provide concrete intervention strategies to prevent suicide in elderly people.

A sedimentation study of the Cheonripo intertidal beach sands and its related coastal dune sands, Cheonripo, Seosan Gun, Choongcheong Namdo, Korea has been carried out based on a series of several summer time field surveys. Each subenvironment in the Cheonripo coastal zone, that is, intertidal sand beach and coastal sand dune, could be differenciated in terms of textural parameters. The coastal dune sands are finer than the intertidal beach sands in mean grain size, and the sorting of dune sands is relatively poorer than that of intertidal beach sands. However, the skewness of intertidal beach and dune sands is commonly positive. Such textural parameters are characteristically differentiated on scatter diagrams. A series of megaripple bedform observations for 6 tidal cycle periods(August 13, 14 and 15, 1990) are interpreted to find out migration pattern of bedforms and its related sand migration. Such migration natures are shown on the tables and figures.

PURPOSE: The purpose of this study was to observe the effect of pain and function according to the high and low manual passive coping strategies after whiplash injury. METHODS: The study was tested with 30 patients with neck pain. Coping was measured at after 10 days using the Pain Management Inventory. Group was divided into high passive(experimental) and low passive(control) group. All patients were equally treated with the ordinary therapy. Patients attended physical therapy for 3 times a week, for 6 weeks. Visual analogue scale (VAS) for pain, Pain Disability Index (PDI), neck disability index (NDI), were recorded both before and after the intervention. RESULTS: Each coping strategy group were evaluated after 6 weeks. VAS has been significantly reduced in both groups (p <.05). PDI and NDI was significantly decreased after the experiment before. In the experimental group (p <.001), the control group showed no significant difference. In the comparison between groups VAS was significantly reduced compared with the control group (p <.05), PDI and NDI was significantly reduced compared with the control group (p <.001). CONCLUSION: Low passive coping strategy predicts neck pain and disability recovery. It may be beneficial to assess and improve coping strategy early in whiplash injury.

GPS/Meteorology technique for PWV monitoring is currently actively being researched an advanced nation. But, there is no detailed research on an evaluation of precision of GPS derived PWV measurements during the period of foul weather condition. Here, we deal with the precision of GPS derived PWV during the passage of Typhoon RUSA. Typhoon RUSA which caused a series damage was passed over in Korea from August 30 to September 1, 2002. We compared th tropospheric wet delay estimated from GPS observation and radio-sonde data at four sites(Suwon, Kwangju, Taegu, Cheju). The mean standard deviation of PWV differences at each site is ${\pm}$0.005mm. We also obtained GPS PWV at 13 GPS permanent stations(Seoul, Wonju, Seosan, Sangju, Junju, Cheongju, Taegu, Wuljin, Jinju, Daejeon, Mokpo, Sokcho, Jeju). GPS PWV time series shows, in general, peak value before and during th passage of RUSA, and low after the RUSA. GPS PWV peak time at each station is related to the progress of a typhoon RUSA. We obtained very similar result as we compare GMS satellite image with tomograph using GPS PWV and we could present th possibility of practical use by numerical model for weather forecast.

In plant virus ecology, weeds are regarded as wild reservoirs of viruses and as potential sources for insect-mediated transmission of viruses. During field surveys in 2013-2014, three Leonurus sibiricus plants showing virus-like symptoms were collected from pepper fields in Daegu, Seosan, and Danyang in Korea. Molecular diagnosis assays showed that the collected L. sibiricus samples were infected with either Tomato spotted wilt virus (TSWV), Pepper mild mottle virus (PMMoV), or Beet western yellow virus (BWYV), respectively. Since this is the first identification of TSWV, PMMoV, and BWYV from L. sibiricus, complete genome sequences of three virus isolates were determined to examine their phylogenetic relationships with the previously reported strains and isolates. Phylogenetic analyses performed using full genome sequences of the viruses showed the isolates of TSWV and PMMoV obtained from L. sibiricus are closely related to the pepper isolates of the corresponding viruses. Our results suggest that L. sibiricus could act an alternative host and reservoir of viruses that cause damages in pepper fields.
