인공어초는 1971년부터 시설해오고 있으며, 1999년까지 전국 연안 1,200개소에 약 7,000,000공㎥가 시설되었다 (해양수산부, 2000). 이들 어초는 대부분 침설어초이며, 금후 시설량이 가속적으로 증대될 것으로 예상된다. 그러나 침설어초의 시설량이 증대됨에 따라 매몰을 최소화하고 대상으로 하는 어류의 위집을 극대화 할 수 있는 시설지의 확보가 무엇보다 선결 과제로 대두되고 있다. (중략)

This study is to analyze the Korean translation of "Goseong Chongswaerok" by O Hoeng-muk as a local governor through political ecology. It focuses on how O Hoeng-muk recognized and wrote the interrelation among weather, agriculture, local resident's life, and local policy. The results are summarized in the followings. Firstly, weather was recorded into three types of expression, simple and dynamic expression and agriculture-related expression. Its dynamics was much meaningful and important when weather was related to local resident's life and local or non-local economy and politics. Secondly, weather and local government were conflict under a particular natural condition like severe drought. And society and politics are affected by such a conflict. Thirdly, local people's demonstration was occurred under a certain condition. Bounded agency can be founded in O Hoeng-muk's behavior as a local governor like jinhyul(賑恤), rain rituals, tax collection. Fourthly, the interrelation among weather, agriculture, local people's life, and local policy implemented in a particular local like Goseong ought to be interpreted in terms of multiple scales.

The results of examining the architectural features and changes of the main building of Dogapsa temple which is multi roofs wooden structure are as follows. The passage comparing 'Dogapsa' of <>, account of Lee Ha Gon's trip as the literature showing the appearance of Dogapsa temple in the early 18th century to Borimsa through verse of 'Dutacho' was noticeable. Dogapsa temple at Yeongam was distant over 100 ri from Borimsa temple at Jangheung and it was considered that there were many temples at Mt. Wolchul, Yeongam and there were also many temples to be comparable with it. But, Dogapsa temple was compared to Borimsa temple because verses 'many-storied building is high and immense' of 'Dogapsa' at <> and 'Dogapsa is lower than Borimsa at Jangheung' at 'Dutacho' of <> were interpreted as the existence of multi roofs Buddhist temple which had something in common with Dogapsa and Borimsa and was comparable to them. According to existing materials, it was assumed that the main building of Dogapsa was burnt through the Japanese invasion of Korea in the 52nd year of the sexagenary cycle (Eulmyooebyeon, 1555) and Jungyujaeran (1597), but record of major history of the main buildings of Dogapsa and Borimsa indicated that multi roofs wooden structure of the two temples were built at the same period. Since multi roofs wooden structure of main building of Borimsa was rebuilt in 1692, these buildings existed from the early 18th century to middle 18th century.

To suggest basic research data for a plan raising naturalness of urban park forest, the structure of forest vegetation and bird community were analyzed in four urban parks of Gwangju city. And also, their relationships were discussed. Some of the structural characteristics in the two communities were closely related to each other. Species and individual densities of birds were relatively high in Songjong and Sangmu park showing the vigorous successional progress, but were low in Anchong park with simple vegetation. The bird group that nest and feed in canopy or dead wood held occupy the highest percent in Sajik park with well developed upper layer of forest, the bird group that nest and feed in shrub did in Sangmu park with developed middle layer, and the bird group that feed in ground did in Songjong park with developed low layer. Relationship between the species diversities of forest and birds was not significant. Nevertheless, bird diversity was relatively high in Sajik and Sangmu park with the high proportion of broad-leaved trees in upper and middle layers.

The authors carried out an experiment to measure the hydrodynamic resistance of the gear and the efficiency of otter board of the midwater trawl, which is the same used in the former experiment in this series of studies. The whole resistance of the gear was measured by a 10 ton scale recording tension meter, and they were analyzed into the shearing force and the drag with relevant factors determined in the former experiments. The results obtained can be summarized as follows: 1. The whole drag of gear T(kg) and the drag of net R sub(N) (kg) can be expressed as T=2.15 v super(1.12). R sub(N)=1.96 v super(1.01) (v: towing speed in m/sec) 2. The formula of estimating the drag of net deduced by Koyama's method can be expressed as R sub(N)=4.3$\times$d/l$\times$abv 3. The shearing force and the drag of otter board is about 19 to 22% and 5 to 7% of the drag of net, respectively. Whereas, the shearing coefficient and the drag coefficient calculated by the resistance and the opening of gear are 1.5 and 0.42, respectively.

In this study, we used artificial intelligence algorithms for the prediction of dissolved oxygen in Jindong Bay. To determine missing values in the observational data, we used the Bidirectional Recurrent Imputation for Time Series (BRITS) deep learning algorithm, Auto-Regressive Integrated Moving Average (ARIMA), a widely used time series analysis method, and the Long Short-Term Memory (LSTM) deep learning method were used to predict the dissolved oxygen. We also compared accuracy of ARIMA and LSTM. The missing values were determined with high accuracy by BRITS in the surface layer; however, the accuracy was low in the lower layers. The accuracy of BRITS was unstable due to the experimental conditions in the middle layer. In the middle and bottom layers, the LSTM model showed higher accuracy than the ARIMA model, whereas the ARIMA model showed superior performance in the surface layer.

As an investigation on the catabolite repression system in cellulase production by Cellulomons sp. CS1-1, the organism was tested on the avicel overlay plates containing glucose or cellobiose at a range of concentration and was grown in continuous culture vessel, supplied by cellobiose medium, aiming the enhanced production of extracellular CM-cellulase at low dilution rates. Product inhibition of cellulase action by cellobiose was also tested. The results obtained are: i) no inhibition of CM-cellulase was observed up to 10 mM(3.4mg/ml) cellobiose in the reaction mixture, however 30% inhibition was observed at 20mM and 55% at 50mM, ii) the tests of catabolite repression on the solid media were successful, and avicel degradation was markedly repressed by glucose or cellobiose, iii) at low concentrations of cellobiose, dilution rate 0.05 and $1.0hour^{-1}$, no significant increase was observed in the production of either intra or extracellular CM-cellulase.

Mo2N/Mo double layer which is to be used for gate of the RMOS (refractory metal oxide semiconductor) and interconnection material has been formed by means of low temperature r.f. reactive sputtering in Ar and N2 mixture. The sheet .esistance of 1 000$\AA$Mo2 N/4000$\AA$Mofilm was about 1.20-1.28 ohms/square, which is about an order of magnitude lower than that of polysilicon film. The workfunction difference naE between MO2N/MO layer and (100) p-Si with 6-9 ohm'cm resistivity obtained from C-V plots was about -0.30ev, and the fixed charge density Qss/q in the oxide was about 2. Ix1011/cm2. To evaluate the signal transfer delay time per inverter stage, an integrated ring oscillator circuit consisting of 45-stage inverters was fabricated using the polysilicon gate NMOS process. The signal transfer delay time per inverter stage obtained in this experiment was about 0.8 nsec

Inductively coupled plasma (ICP) excited by a spiral planar antenna is used to etch elctrodes for PZT capacitors. Pt/RuO$_{2}$ bilayers are tested as bottom electrodes for PZT capacitors in order to utilize better leakage characteristics of Pt and easy etch characteristics of RuO$_{2}$ at the same time. The etch rates and selectivities to SiO$_{2}$ hard mask have been measured for each of Pt and RuO$_{2}$ in terms of various plasma conditions. As Cl$_{2}$ ratio increases in $O_{2}$/Cl$_{2}$ mixture, the etch rate of Pt increases while that of RuO$_{2}$ reaches the highest near 10 ％ of Cl$_{2}$. Optimum gas mixture ratio has been determined for etching Pt and RuO$_{2}$ bilayers sequentially, and sub-half micron patterning is demonstrated.

All the phenomena and subjects of nature and society are within correlation interconnection, and they are inseparably connected one another. The elements of this interaction can be found out through the concept of transparency in the space composition of Korean traditional architecture. This study is focusing on the access space, in other words, a gate-house that is a buffer zone playing a process role up to the main space among successive spaces. It was chosen to be the subject of the study since it strengthens convergence into the main building and with the effect connecting spaces, it could show well the spatial possibility of transparency. Besides, the subject of the study is limited to the Moonru Multi roofs that improves the functionality of spaces between gate-houses, and it is intended to progress contents by comparative analysis of two kinds such as Seo Won gate-house and temple gate-house. Korean traditional architecture places emphasis on harmony within the whole spaces. There are intimate relations between surrounding environment, external spaces and internal spaces, and it is important understand the spatial relations according to the shape appearing through interactions of parts in the whole spaces. In conclusion, the Moonru Multi roofs is analyzed with the method of extracting the concept that is contained in the frame of analysis and through ecological views through a visible and structural method. It can be understood what kinds of method for communication were used for ancestors to recognize and use spaces with the deduced concept through the analysis of the Moonru Multi roofs with different character.
