심혈관계 질환(CVD, Cardiovascular disease, CHD, Coronary heart disease)은 심장의 관상동맥에 염증반응과 혈전으로 인해 죽상경화중이 생겨 관상동맥이 좁아지거나 막히는 결과를 초래하는 질환으로 관상동맥질환, 고혈압, 말초혈관질환, 협심증, 심근경색증, 중풍 등이 포함된다. 심혈관계 질환의 위험인자들에는 서구화된 식생활, 유전, 나이, 성, 고혈압, 당뇨, 고지혈증, 비만, 운동부족, 스트레스, 흡연, 가족력 등이 있다. 그러나 식생활의 변화로 인한 심혈관계 질환과 생화학적 지표의 변화 및 관련 기전에 대한 연구는 거의 없었다.(중략)

우리 민족 전래의 발효식품인 김치는 많은 생리활성물질들이 존재하는 다양한 재료를 사용하여 만들어지며 여러 효소와 미생물들이 관여하는 복잡한 발효과정을 거치면서 또다른 생리활성물질들을 생성한다. 이들 물질은 복합적으로 작용하여 항산화활성을 나타내며 실험방법들에 따라 조금씩 다른 양상을 보이지만 김치 재료물질들의 종류 및 함량, 발효정도 등은 김치의 항산화성에 중요한 영향을 미치는 인자들이라고 할 수 있다. 본 총설은 김치의 항산화성을 in vitro 및 in vivo수준에서의 연구결과들을 중심으로 살펴보았다.

좁은 면적에서나마 좀더 많은 수확을 얻으려는 노력은 부단히 계속되고 있다. 그러나 인구는 나날이 불어가고 경작면적은 제한되어 있기 때문에 그 문제점은 더욱 커지고 있는 것이다. 소위 재배에 적합하다는 고래로부터의 농경지에서만이 식량생산이 가능한 것일까? 하지만 이는 옛말이 되고 말았다. 모래밭에서 노다지를 캐낼 수 있기 때문이다. 고대 농대의 김용길 교수는 녹색식물의 영양, 생장, 광합성에 관한 능력발휘의 어느한계 이상에서는 토양이 오히려 제한적 인자로 등장한다고 지적하면서 이와같은 단점을 배제한 관권농법과 모래땅의 식물재배법을 연구 발표하였다. 토양의 제한성을 제거하고 근권매지에 새로운 영양환경을 조성하여 작물생산능력을 극대화하자는 것이 김교수의 주장이다.

The factor, which was capable of accelerating the yeast cell wall lysis of the zymolyase(${\beta}-1$, 3-glucanase), was purified to a homogeneous state from the protease fraction of the crude zymolyase by Sephadex G-75 gel filtration and preparative polyacrylamide gel disc electrophoresis. The molecular weight of the purified factor was estimated to be 40,500 by SDS-polylacrylamide gel disc electrophoresis and it's iso-electric point was pH 9.6. The factor was found to be a basic protease consisted of single polypeptide chain with 395 amino acid residues and it showed the $E_{280,cm}^{1%}$ of 11.9 and the molecular extinction coefficient of $4.83{\times}10^4$, respectively.

In Yeongsan River estuary, located in the southern West Coast, a dike was constructed in December 1981. After the construction of a dike, discharge mechanism of fresh water has been changed, the water quality and chlorophyll-a are expected to be influenced by fresh water discharge. We investigated temporal and spatial variations and long-term trend of phytoplankton biomass (chlorophyll-a) and environmental factors. The concentrations of nutrient and chlorophyll-a were generally high in summer and the concentrations were increased toward downstream. Surface/bottom salinity difference was negatively correlated with salinity in surface water but positively with nutrient and chlorophyll-a. TN, TP and DIN concentrations were generally increased over 10 years. This study can provide information for better management of water quality for Youngsan River estuary.

Effective nutrition educations for prevention of chronic diseases for the general population are of great importance these days. The purpose of this study was to evaluate the feasibility of nutrition education for cardiovascular risk factor reduction by e-mail education in male workers. The participants were divided into three groups by age; 28-39 age group, 40-49 age group, and 50-59 age group who got regular checkups for anthropometry and biochemistry. The 1 year program consisted of 15 topics containing information about metabolic syndrome (MS) and healthy eating behavior (intake of salt, fat and alcohol). Seven hundred thirty nine participants volunteered for the study [28-39 age group, n = 240; body mass index (BMI) = 24.9 $\pm$ 2.7 kg/m$^2$: 40' group, n = 276; BMI = 24.8 $\pm$ 2.6 kg/m$^2$: 50' group, n = 223; BMI = 24.9 $\pm$ 2.7 kg/m$^2$]. Percentage body fat (p < 0.05) and percentage of abdominal fat (p < 0.05), total cholesterol (p < 0.05), systolic blood pressure (p < 0.05), and diastolic blood pressure (p < 0.05) were significantly decreased in all participants after the 1 year program. The total number of participants who had MS was decreased from 216 to 199 and especially the incidence of MS was decreased 27% in the group of subjects who were under the age 39. The e-mail worksite nutrition education program shows a substantial contribution to the development of effective CVD and chronic disease control and lifestyle nutrition educations that are applicable to and attractive for the large population at risk.

In this study, the nutrient concentration changes along the hydrologic flow path of a free water surface flow constructed wetland (CW) treating agricultural stream runoff was investigated. Dry sampling was performed from April 2009 to November 2011 at five locations representing each treatment units of the CW. Grab water samples were analyzed for nitrogen forms such as total nitrogen (TN), total Kjeldahl nitrogen, nitrate, and ammonium; and phosphorus forms including total phosphorus (TP) and phosphate. Findings revealed that the physical properties such as temperature, dissolved oxygen and pH affected the TP retention in the CW. High nutrient reduction was observed after passing the first sedimentation zone indicating the importance of settling process in the retention of nutrients. However, it was until the 85% of the length of the CW where nutrient retention was greatest indicating the deposition of nutrients at the alternating shallow and deep marshes. TN and TP concentration seemed to increase at the final sedimentation zone (FSZ) suggesting a possible nutrient source in this segment of the CW. It was therefore recommended to reduce or possibly remove the FSZ in the CW for an optimum performance, smaller spatial allocation and lesser construction expenses for similar systems.
