정부가 대 중소기업간 상생협력을 본격 추진하기 위해 지난해 말 동반성장위원회를 구성하면서 동반성장 정책이 활기를 띄고 있다. 올해 말에는 56개 대기업(건설사 12개 업체)의 동반성장 및 공정거래 협약 실적이 평가 된다. 이에 따라 대기업은 동반성장 협력 방안을 잇달아 내놓고 있다. 지난 4월 15일 10대 대형건설사가 공정거래 및 동반성장 협약을 체결한 것도 정부의 이러한 정책을 반영하기 위함이다. 서울시 등 일부 지자체도 상생을 위한 하도급 정책을 속속 내놓고 있다. 서울시는 하도급 문화 개선 을 위해 ${\Delta}$하도급 직불제 ${\Delta}$표준계약서 사용 ${\Delta}$주계약자 공동도급제 등 3가지 분야를 확대시행 정책 과제로 삼고 올해부터 집중 추진하기로 했다. 인천시 종합건설본부도 4월부터 하도급 대금 직불제 시행에 들어갔다. 본지는 핫이슈로 떠오르고 있는 정부의 동반성장 정책 방향 및 제도개선 현황과 서울시의 하도급 정책, 동반성장지수 평가 대상업체인 12개 건설사의 상생협력 방안에 대해 알아본다.

Purpose: This study was performed to evaluate the cereal intake status and explore its relationship with the nutritional status of the Korean adults from 2013 ~ 2016, Korean National Health and Nutrition Examination Survey (KNHANES). Methods: We analyzed dData from the combined 2013 ~ 2016 Korean National Health and Nutrition Examination Survey were analyzed. The analysis included 12,199 adults aged from 19 to 64 years (male, n = 5,127, female, n = 7,072). In this study, according to cereal intake frequency (From food frequency questionnaire), we classified tThe subjects were classified according into the "non-cereal intake (NCI)" group (male, n = 4,290, female, n = 5,578), and "cereal intake (CI)" group (male, n = 837, female, n = 1,494) according to cereal intake frequency (From food frequency questionnaire). Results: Typically, 79.6% of adults did not consume cereals (male 81.6%, female 77.3%);, 13.4% consumed cereals 1-3 times a month (male 12.2%, female 14.8%) and 7.1% consumed cereals more than once a week (male 6.2%, female 7.9%). In the case of both males and females, the nutrient density (nutrient intake per 1,000 kcal) and Index of Nutritional Quality (INQ) of protein, calcium, phosphorous, potassium, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin, and vitamin C in the Non-Cereal group were significantly lower than those of the CI group (respectively, p < 0.01). Conclusion: Our These results reveal highlight the low frequency of cereal intake in Korean adults and the better nutritional status in adults who consume cereals. It is hypothesized that tThe data of the present study would is expected to serve as basic data to improve the nutritional status of Korean adults.

An adequate exposure is important in thoracoscopic procedures. The insufflation of $CO_2$has been demonstrated to aid in compressing lung parenchyma, and act as a retractor when combined with changes in patient's position. However, a recent study demonstrated that $CO_2$insufflation during thoracoscopy in the pig has adverse hemodynamic consequences. We prospectively studied 12 patients undergoing thoracoscopy to evaluate the effect of $CO_2$insufflation in the clinical setting. The mean arterial pressure, heart rate, central venous pressure, arterial oxygen saturation, and end-tidal $CO_2$pressure were monitored. Measurements were determined at baseline, at the initiation of one-lung ventilation, and at intrapleural pressure of 5, 10, 15 mmHg and following results were obtained. 1) The insufflation of 5 to 15 mmHg of $CO_2$had no significant effect on the mean arterial pressure, heart rate, arterial oxygen saturation. 2) The end-tidal $CO_2$pressure rose from 31.00$\pm$1.67 mmHg to 38.49$\pm$1.82 mmHg at an intrapleural pressure of 15 mmHg(p<0.05). 3) The central venous pressure rose from 7.75$\pm$0.76 mmHg to 12.83$\pm$1.64 mmHg and 16.16$\pm$l.97mmHg at an intrapleural pressure of 10 and 15 mmHg(p<0.05). 4) The low pressure (<10 mmHg) insufflation is a safe adjunct to the conduct of thoracoscopic surgical procedures.

This study was to carried out to estimate the relationship between acceleration storage and room temperature storage of gangjung (control unit) and dried insam gangjung (experiment unit), by acid value and peroxide value. The result were summarized as follows. : 1. Test for acid value of control unit, every 1 hour after acceleration storage is similar to each 7 days after room temperature storage is imilar to each 7.5 days after room temeprature storage. 2. Test for peroxide value of control unit, evry 1 hour after acceleration storage is similar to each 7.5 days after room temperature storage but to test peroxide value of experiment unit, every 1 hour after acceleration storage is imilar to each 7.7 days after room temperature storage. 3. In case of the oxidized flavor, control unit is not detected during storage stability but the experiment unit is detected unit is detected 1 hour ahead of acceleration storage than room temperature storage.

이번 고병원성조류인플루엔자(이하 HPAI로 기술)는 2008년 4월 1일 우리 전라북도 김제시 용지면 산란계 밀집 사육지역에서 시작하여 5월 12일 경북 경산시 토종닭 농장을 끝으로 11개 시 도 19개 시 군 구에서 총 33건이 발생되어 2,6410억원의 경제적 피해가 발생하였다. 우리 전라북도는 최초 발생농가를 포함 4개 시 군(익산, 정읍, 김제, 순창)에서 17건(닭13, 오리 4)이 발생하여 전국에서 HPAI발생이 가장 많았던 도로 남는 불명예를 안게 되었다. 이에 막대한 경제적 피해가 다시 발생하지 않도록 HPAI의 현장 방역에 대해 나름대로 경험한 것과 느꼈던 것들을 사례별로 기술하고자 한다.

Following a preceding study of Shin et al.(2004), wave fields for a month of September of 2003 are simulated based on the modified WAM cycle 4 model that enables the precise wave hindcasting with fine spatial meshes, and characteristics of extreme waves at the south coast of Korea are analyzed The accuracy of applied wave model is verified by comparing computed wave parameters and corresponding ones measured at Ieodo ocean research station. The wave hindcasting of typhoon 'Maemi' with an hour time interval reveals the extreme wave characteristics at 4 primary locations of south coast of Korea as follows: 1) At the front sea of Chaguido in the south of Jeju-do, the maximum significant wave height, mean wave period and mean wave direction appear to be 7.41m, 13.65s and $6.4^{\circ}$ respectively at 16:00 KST of Sep. 12, 2003. 2) At the entrance of Masan Bay, 12.50m, 13.65s and $1.2^{\circ}$ at 21:00 KST of Sep. 12. 3) At the front sea of Suyoung Bay, 13.85m, 13.81s and $0.2^{\circ}$ at 22;00 KST of Sep. 12. 4) At the front sea of Ulsan port, l1.00m, 13.25s and $2.8^{\circ}$ at 23:00 KST of Sep. 12.

In this paper, a new time delay estimation algorithm, WTD-LMSTDE was proposed. This method has great improvement in convergence rate relative to the time domain approach by decreasing the eigen value spread of input signal autocorrelation matrix. The performance of the algorithm was evaluated for the cases of time invariant time delay and time varying time delay. In the case of time invariant time delay, the estimation accuracy of WTD-LMSTDE was better than that of LMSTDE from 3.3% to 12.5% with respect to SNR. In the case of time varying time delay, the mean error power of WTD-LMSTDE in linear increased delay environment was decreased about 2.4dB compared to that of LMSTDE under noise-free condition. As a result, we showed that the performance of WTD-LMSTDE is better than of LMSTDE.
