월악산 국립공원 내의 소나무군락에서 2005년 5월부터 2008년 4월까지 3년 동안 월별 낙엽의 생산량과 낙엽을 통해 임상에 이입되는 영양염류의 양을 조사하였다. 2005, 2006, 2007년의 낙엽생산량은 각각 3.070, 3.066, 3.099 ton ha-1 yr-1이었으며, 3년 동안의 평균 낙엽생산량은 3.078±0.018 ton ha-1 yr-1이었다. 낙엽 구성원 중 침엽, 가지 및 수피, 생식기관 그리고 기타가 차지하는 비율은 각각 61.9, 10.4, 5.2, 22.5%으로 침엽이 차지하는 비율이 가장 컷다. 조사지소에서 3년 동안 낙엽을 통해 임상에 이입되는 질소, 인, 칼륨, 칼슘 그리고 마그네슘의 평균 양은 18.014, 0.878, 4.240, 7.349 그리고 2.172 kg ha-1 yr-1이었다.

생물학적인 과정으로서 분만과 관련된 공포와 불안은 임상적으로 흔하며 흥미로운 것으로 여겨졌지만, 임신의 결과가 양호한 경우 대부분 중요하게 연구되지 않았다. 본 연구에서는 분만 공포를 이해하기 위해 534명의 한국인 산모를 대상으로 불안, 공포, 통증과 관련되어 있다고 알려진 5-HTT의 단일염기 다형성을 조사하였다. 534명의 한국인 산모에서 단일염기 다형성 빈도는 5-HTT -15375 insdel (44 bp) 0.24, -1002A>C 0.10, -922A>C 0.11, +18784A>C 0.073이었으며, +3746G>C는 한국인 산모에 있어 유전적 다형성이 없었다. 분만 공포와 유전적 다형성의 연관성을 연구하기 위해 534명 중 자연분만을 시행한 293명의 산모들을 대상으로 분만공포지수를 이용하여 분만 공포를 평가하였으며 분만력으로 보정한 다중회귀분석을 사용하여 분석하였다. 본 연구에서 5-HTT유전자의 단일염기 다형성은 분만 공포와 상호연관성이 없었다. 분만 공포는 유전적 요소인 5-HTT 유전자의 다형성 보다 심리적, 사회적, 환경적 요인 등이 더 중요한 역할을 하는 것으로 보이며 다른 유전자들과 유전자간의 상호 작용에 의해 복합적 영향을 받는 것으로 생각된다. 따라서 분만 공포를 이해하기 위해 이후 사회적, 심리적, 환경적 요소와 이와 관련된 유전자의 상호연관성에 대한 연구가 포괄적으로 진행되어야 할 것이다. The fear and anxiety in the biological processes of childbirth have been of clinical interest, but the studies addressing this subject are rare, particularly where the outcome of the pregnancy has been favourable. In this study, single nucleotide polymorphisms were studied for understanding the fear during childbirth in 534 Korean pregnant women. The frequencies of each SNP were 5-HTT -15375 insdel (44 bp) 0.24, -1002A>C 0.10, -922A>C 0.11, +18784A>C 0.073 in Korean pregnant women (n=534). No polymorphisms was found in 5-HTT +3746G>C The relationship between the fear during childbirth and genetic polymorphisms was investigated by multiple regression analysis adjusting for parity in 293 women who gave birth to a child vaginally and made a reply to Delivery Fear Scale (DFS) which was the measuring instrument for the fear during childbirth among 534 Korean pregnant women. There was no genetic association between the 5-HTT gene polymorphism and fear during childbirth. The results of this study show that the psychological, social, environmental factors play the major role in the fear during childbirth whereas this gene (5-HTT) most likely has only a minor effect in its etiology. And other genes and the interactions between them have been thought to make complex effects. In order to identify the fear during childbirth, further studies will have to be focused on the comprehensive research of the social, psychological, environmental factors and the interaction of the connected genes.

Mass loss and dynamics of mineral nutrient during decomposition of deciduous leaves and 3 species of needles were investigated for 38 months from October in 1992 to November in 1995 in Kwangneung, Korea. After 38 months, the remaining mass of deciduous leaves, Pinus koraiensis, Pinus rigida and Abies holophylla was 16.2%, 29.8%, 33.5% and 53.9%, respectively. The decay rate (k) of deciduous leaves, Pinus koraiensis, Pinus rigida and Abies holophylla was 0.61, 0.40, 0.37, 0.21yr^-1, respectively. The lowest decay rate in fir needle might be, in part, due to low N concentration. N concentration of the decomposing litter increased during the experimental period except for P. rigida. Deciduous leaves showed a short immobilization period during the early stage of decomposition, and big-cone pine and pitch pine had no immobilization period. However, there was no net N mineralization in fir litter. P increased during the experimental period for all litter. Except for deciduous leaves, there was no net mineralization period. In case of deciduous leaves, however, remaining P after 38 months was 53% of the initial P capital. Remaining cations of the decomposing litter after 38 months were lower than those of initial contents.

In order to obtain necessary data for the use of hydrophytes to improve water quality of artificial lakes, production and nutrients absorption by some macrohyrophytes were investigated in a small water course at Woongcheon, Chungnam Province. The maximum above-ground standing biomass of Phragmites communis, Typha angustifolia and Zizania latifolia stand were 3,504g/㎡, 2,834g/㎡ and 3,125g/㎡, respectively. Estimated below-ground standing biomass of each stand were 9,671g/㎡, 5,158g/㎡ and 5,813g/㎡, respectively. Concentration of nutrients in each organ was different among plant species. Maximum amount of standing nitrogen was the highest in the reed stand and that of standing phosphorus was the highest in the cattail stand. Amount of maximum standing nutrients are 2795.6㎏N/㏊ and 42.5㎏P/㏊ for the reed stand, 1,414㎏ N/㏊ and 24.8㎏P/㏊ for the cattail stand and 1.901,1㎏N/㏊ and 38.4㎏ P/㏊ for the wild rice stand, respectively. According to our investigation, it is concluded that reed, cattail and wild rice are suitable for water quality improvement of artificial lakes through nutrients absorption.

Mass loss and changes of mineral nutrient during the decomposition of Typha angustata for 13 months from November in 1998 to December in 1999, were investigated in small watercourse in Boryeong, Chungnam Province, Korea. After 13 months, remaining mass of leaves, stems and rhizomes was 34.7%, 59.2%, 7.2%, respectively. The rate of weight loss of the rhizomes was significantly higher than those of the leaves and stems. The decay rate of leaves, stems and rhizomes was 1.06, 0.52, 2.63 yr^-1, respectively. Initial concentration of nutrients in leaves, stems and rhizomes was 11.5, 9.0, 14.5 ㎎/g for N, 0.30, 0.27, 0.47 ㎎/g for P, 20.7, 26.9, 26.6 ㎎/g for K, 14.50, 4.77, 3.25 ㎎/g for Ca, and 1.99, 1.32, 2.07 ㎎/g for Mg, respectively. Except for Ca, concentrations of nutrients in rhizomes were higher than those in stems and rhizomes. There was no immobilization period during the decomposition of each organ of T. angustata. In case of K, most are lost during the first 1 month. Phosphorus in decomposing leaves and stems lost 58% and 66%, respectively, of the initial P capital within 1 month.

The RIL Based Approach for Predicting the Growth of Pearl Spot Fish Using-UWAC
Delphin Raj K M(델핀라즈),Soo-young Shin(신수영),Jeong-Il Namgung(남궁정일),Soo-Hyun Park(박수현) 대한전자공학회 2018 전자공학회논문지 Vol.55 No.8
Pearl spot은 인도 케랄라주에서 흔히 “Karimeen”이라고 알려진 Etroplus suratensis로 인도 반도의 동부와 남서쪽 해안을 따라 광범위하게 발견되며 케랄라주에서 널리 이용되는 어종 중 하나이다. 가두리 양식 방법에서는 어류의 성장을 효과적으로 관찰하기가 어렵다. 전통적인 어류 모니터링 시스템 방법들은 높은 비용 및 배터리 사용, 주기적인 카메라 렌즈 청소, 정기적인 모니터링 등과 같은 많은 단점이 있다. 수중음향통신(UWAC)은 어류의 성장 모니터링에 있어서 전망이 있는 접근법 중 하나이다. 이 논문에서 우리는 케이지 안에 있는 다양한 크기의 어류(Pearl spot)의 성장을 예측하기 위해 수중음향통신(UWAC)을 기초로 한 수신된 음강도레벨(RIL)을 제안하였고, 음향 트랜스듀서는 케이지 안에서 음파를 송수신하는데 사용된다. 제안된 시스템은 온도, 산소, pH, 염도 등과 같은 수질 매개변수를 모니터 할 수 있기에 어류의 건강을 능률적으로 추적 관찰 할 수 있다. 따라서 제안된 시스템의 수중 센서와 수중음향통신(UWAC)은 각각 어류의 건강을 모니터링, 예측하는데 사용 가능할 것으로 사료된다. The Pearl spot, Etroplus suratensis commonly known as “Karimeen” in Kerala, is extensively found along the east and south-west coasts of Peninsular India, and is one of the widely used species of Kerala. In cage farming method, it is difficult to observe the growth of fish efficiently. The traditional approaches for fish monitoring system has many disadvantages such as high cost, low battery power, cleaning camera lens periodically, regular monitoring, etc. Underwater Acoustic Communication (UWAC) is one of the promising approaches of fish growth monitoring. In this paper, we propose the Received Intensity Levels (RIL) based approach to predict the growth of pearl spot fish inside the cage at different levels. An acoustic transducer is used for sending and receiving acoustic waves inside the cage. The proposed system can monitor the water quality parameters such as Temperature, Oxygen, pH, Salinity, etc., thereby efficiently monitoring the health of the fish. In addition, UWAC and acoustic transducer can be used for fish growth prediction at different levels inside the cage.
