한국어의 언어적 특성에 의해 빈번하게 등장하는 명사와 기능어의 나열은 기능어나 연결 구문의 잦은 생략현상에 의해 복합 명사의 출현을 발생시킨다. 따라서, 한국어 분석에서 복합 명사의 처리 방법은 매우 중요한 문제로 인식되었으며 활발한 연구가 진행되어 왔다. 복합 명사의 의미 결정은 복합 명사구 내 단위 명사간의 의미적인 수식 관계를 고려하여 머리어의 선택과 의미를 함께 결정할 필요가 있다. 본 논문에서는 정보 검색의 색인어 추출 방법에서 사용되는 복합 명사구 내의 서술성 명사 처리를 이용하여 복합 명사의 의미 결정을 인접 명사의 의미 공기 정보가 아닌 구문관계에 따른 의미 공기 정보를 사용하여 분석하는 방법을 제시한다. 복합 명사구 내에서 구문적인 관계는 명사구 내에 서술성 명사가 등장하는 경우 보-술 관계에 의한 격 결정 문제로 전환할 수 있다. 이러한 구문 구조는 명사 의미를 결정할 수 있는 추가적인 정보로 활용할 수 있으며, 이때 구문 구조 파악을 위해 구축된 의미 제약 조건을 활용하도록 한다. 구조 분석에서 사용되는 격틀 정보는 동사와 공기하는 명사의 구문 관계를 분석하기 위해 의미 정보를 제약조건으로 하여 구축된다. 이러한 의미 격틀 정보는 단문 내 명사들의 격 결정과 격을 채우는 명사 의미를 결정할 수 있는 정보로 활용된다. 본 논문에서는 현재 개발중인 한영 기계 번역 시스템 Tellus-KE의 단문 단위 대역어 선정을 위해 구축된 의미 대역패턴인 동사구 패턴을 사용한다. 동사구 패턴에 기술된 한국어의 단문 단위 의미 격 정보를 사용하는 경우, 격결정을 위해 사용되는 의미 제약 조건이 복합 명사의 중심어 선택과 의미 결정에 재활용 될 수 있으며, 병렬말뭉치에 의해 반자동으로 구축되는 의미 대역 패턴을 사용하여 데이터 구축의 어려움을 개선하고자 한다. 및 산출 과정에 즉각적으로 활용될 수 있을 것이다. 또한, 이러한 정보들은 현재 구축중인 세종 전자사전에도 직접 반영되고 있다.teness)은 언화행위가 성공적이라는 것이다.[J.

Cellular glass foam (CGE), the reprocessed glass, has a possibility as a component of vegetative propagation media of floricultural crops due to the its excellent air and water permeability, similar to that of perlite. An experiment was conducted to evaluate the rooting and growth thereafter of Kalanchoe blossfeldiana ‘Gold Strike’in media containing various volume ratios of granular rockwool, peat-moss, CGF and perlite. The particle size of CGF and perlite was 2.0~4.0mm and 1.2~4.0mm, respectively. Cuttings were rooted in a fog tunnel with a mean temperature of 18.2$^{\circ}C$ and RH of 66.7％ under a long day regime (14 h per day light period). Height, length of the longest root, stem diameter, no. of leaves, leaf area, percentage of rooted cuttings, shoot and root fresh weights, shoot and root dry weights, total chlorophyll concentration and physicochemical properties were measured. Cuttings rooted 100% in all treatments. Physicochemical properties in CGF and perlite-containing media showed little differences. The growth of rooted plants in the CGF-containing media was similar or rather superior to that in perlite-containing media. Consequently, CGF has a possibility as a vegetative propagation medium of Kalanchoe. To make wider commercial use of CGF, more demonstrative experiments and analyses are necessary.

BACKGROUND: This study was conducted to evaluate the effects of the fertilizer sources and ground cover mulches on nutrient release, growth, and photosynthesis in small one-year-old apple (Malus ${\times}$ domestica Borkh.) trees in controlled conditions. METHODS AND RESULTS: Treatments included no fertilizer (NF), commercial organic fertilizer (CF), and poultry litter (PL) for fertilizer treatments, and wood chips (WC), shredded paper (SP), green compost (GC), and grass clippings (GR) for cover mulch treatments. All treatments were applied proportionally based on the volume ratio equivalent to the soil. CF, PL, and GR treatments that had optimum carbon (C) and nitrogen (N) ratios (less than 30:1) for N mineralization through the microbes released the greatest $NH_4^+$ concentrations in the pot media at 90 days after the treatments, but GC mulch with the optimum C:N ratio did not. CF-, PL- and GR-treated plants had the largest leaf area, thickest stem diameter, longest shoot extension, and greater dry matter production. CONCLUSION(s): CF and PL showed an suitable organic nutrient source for improving plant growth in an orchard. Interestingly, GR also could be a nutrient source for tree growth, if vegetation competition is controlled by maintaining vegetation height and recycling enough grass clippings to the soil in an orchard.

Increase in demotion and repair works on buildings in the construction market generates a large amount of construction waste. Recycling of construction waste is important for saving of resources, preservation of environment and constant advance of the construction industry. Accordingly, the environmental and economic value of recycled aggregate, which is produced after waste concrete is crushed, is increasingly highlighted. It is generally known that compared to concrete made of ordinary aggregate, concrete made of recycled aggregate has low quality, and the low quality is dependent on the amount of the bonding heterogeneous (cement paste and mortar) as well as the amount of the pores within the bonding heterogeneous. Reports on carbonation mechanism shows that the pores of cement-based materials are filled up by the progress of carbonation. Therefore, this study aims at an estimation of the period for optimum carbonation reforming appropriate for the thickness of the bonding heterogeneous of recycled aggregate, based on carbonation mechanism, with a view to improving the product quality by means of filling up the pores of the bonding heterogeneous of recycled aggregate. This study drew the carbonation depth according to the passage of age by calculating the bonding ratio and bonding thickness of the bonding heterogeneous as against the particle size distribution of recycled aggregate as well as by chemical quantitative analysis according to the age of accelerated carbonation of mock-up samples imitating bonding heterogeneous. Based on the correlation between the age of accelerated carbonation and carbonation depth, this study also proposed the estimated period of carbonation reforming of recycled aggregate appropriate for the thickness of the bonding heterogeneous.

This study was conducted in an effort to meet the need for domestic production of hydroponic media and for medium development using recycled hydroponic rockwool slabs. Two experiments were conducted to evaluate the growth of plug seedlings of petunia 'Romeo' in various mixtures including particles of used rockwool slabs (rockwool particles) and wood chips. In the first experiment, seedlings were grown in plugs filled with mixtures of steam- sterilized rockwool particles and chestnut wood chips, which had been weathered for six months and screened through either 2.8 mm or 5.6 mm sieve, at the mixing ratio of 100:0, 75:25, 50:50, 25:75, or 0:100 (v/v). In the second experiment, seedlings were grown in plugs filled with twenty different mixtures of steam-sterilized particles of used hydroponic rockwool slabs with 4 mm chestnut or pine wood chips, coir, peatmoss, or perlite. In the first experiment seedling growth was not affected by particle size of chestnut wood chips, was superior in the control (commercial plug medium) and in 100% rockwool particles, but was suppressed as mixing ratio of chestnut wood chips increased. In the second experiment, leaf length, and shoot fresh and dry weights were the greatest in rockwool particles+peatmoss+coir treatment, followed by rockwool particles+peatmoss treatment. Leaf length was suppressed as ratio of wood chips increased, especially of chestnut wood chips. Root development was the greatest in rockwool particles+peatmoss+perlite treatment, followed by the control, and rockwool particles+peatmoss+coir treatment. The growth was suppressed as the mixing ratio of rockwool particles, peatmoss, or coir decreased.

The aim of this study, a traditional residential area in the environmentally friendly design techniques to identify the techniques and principles that have been carried out to reestablish the principles. To do this, through literature review environmental performance is reflected in the traditional residential area side of resources conservation, locational aspects, spatial configuration, and how cases were selected looking for ways to apply modern. Are examples of upper class housing in the Chosen Dynasty Period period construction relatively well-preserved round and a good building with a clear housing Dokrakdang year were selected. Locational aspects of the terrain with minimal changes to the building and construction techniques were entirely in terms of environmental conservation and environmental temperature was adjusted to regulate the room temperature technique could be seen. In terms of cycling in natural materials were recycled. and water make used of positive through water cycling technique & water control. In addition, the importance of landscape views overlooking the landscape from inside to outside through the regulation of the various internal and external space technique was used to attract and expand. Traditionality in the pursuit of modern space, simply cut off because of tradition rather than to restore or recover the organizing principle inherent in the traditional space, and extraction of the contemporary social, cultural and environmental understanding of space is acceptable in basis. Environmentally-friendly design techniques in a traditional residential area for a long time to be developed by the experience of its application of modern environmental and energy problems and pleasant environment to the creation of human life and are subject to significant swings in that.

Production cost as well as environmental contamination can be reduced by reuse of drained nutrient solution in hydroponic. This research was conducted to obtain the information in changes in inorganic elements concentration of supplied and drained nutrient solution as well as of plant leaves. To achieve the objective, the samples of supplied and drained solution and cherry tomato leaf tissues were periodically collected and analyzed during the hydroponic cultivation. The electrical conductivity (EC) of supplied and drained nutrient solution in early growth stage of cherry tomato were measured as around $2.0dS{\cdot}m^{-1}$, but those values move up with the passage of time reaching to $2.0dS{\cdot}m^{-1}$ at flowering stage of 9th fruiting node. The pHs of drained solution in early growth stage were 6.4 to 6.7, however those showed a tendency to get lowered to 5.9 to 6.1 as time passed during the crop cultivation. The concentration differences of $NO_3-N$, P, K, Ca, and Mg between supplied and drained solution were not distinctive until flowering stages of 4th fruiting nodes, while those in drained solution moved up after the stage. The tissue N contents of leaves decrease gradually and those of K and Ca increased as crops grew. However, Tissue P and Mg contents were maintained similarly from transplant to end-crop. The above results would be used in correction of drained nutrient solution when element compositions are varied compared to supplied solution in hydroponic cultivation of tomatoes.

This paper explores the photocatalytic sensitivity of cement mortar incorporated with recycled $TiO_2$ from waste water sludge. Basically, $TiO_2$ cluster sank down slowly to the bottom of cement mortar specimen before setting and hardening process. This leads the mismatch of $TiO_2$ concentration on the top and the bottom faces of a specimen. This poorly dispersed $TiO_2$-cement mortar naturally exhibits poor NOx removal efficiency especially on the top of cementitious structure. In architectural engineering application such as building or housing structures, one can simply filp over from the bottom so that more $TiO_2$ concentrated surface can be placed outward into the air. However, in highway pavement case, this could not be applicable due to in-situ installation of concrete pavement. Hence, the dispersion of $TiO_2$ cluster inside the cementitous material is getting important issue onto road construction application. To elaborate this issue, according to our results, silica fume, high-ranged water reducer, viscosity agent, blast furnace slag were not enhanced much of dispersion characteristics of $TiO_2$ cluster. The combination of foaming agent and accelerator of hardening with viscosity agent and small grain size of fine aggregate may help the dispersion of $TiO_2$ inside cementitious materials. Even though the enhanced dispersion were applied to the specimen, NOx removal efficiency doest not change much for the top surface of the specimen. This concurrently affected by the presence of tiny air voids and the dispersion of $TiO_2$ in that these voids could easily adsorbed NOx gas with the aid of large surface area.

This study was conducted to investigate the horticultural media + decomposed granite + reused rock wool in the following mixing ratio: Control = 100:0, M1 = 80:0:20, M2 = 60:30:10, M3 = 40:30:30, M4 = 30:40:30, M5 = 0:50:50 (reused rockwool : decomposed granite : horticultural media) and develop the physicochemical properties and the growth of 'Sulhyang' strawberry runner plant. In the physical aspect of the horticultural media, statistical differences were recognized that the bulk density and particle density were lower in the control and M1. But the bulk density and particle density were high in the M3, M4, and M5, because it had high mixing ratio between recycled rock wool and decomposed granite. EAW and WBC showed a similar tendency. The air porosity and total porosity were higher in control and M1 than M3, M4, M5. Exchangeable cation (K⁺, Ca²⁺, Na⁺, Mg²⁺) and base replacement capacity (CEC) were higher in control and M1, than M2, M3, M4, and M5. As a result of the cultivation of 'Sulhyang' runner plant, the plant length was long in M2, 32.1 cm and smaller than M5 to 28.4 cm. However, if the crown diameter, which is the growth indicator of the runner plant, all 6 treatments were formed 11.23 mm-12.03 mm, which is considered to be suitable for the growth of the runner plant. There wasn't a statistical difference between the weight and dry weight of the root. As a result, the growth difference of the seedlings by the horticulture media was similar. Therefore, considering the physical properties of the horticultural media, it was judged that the air porosity and total porosity would be improved when the recycled rock wool and the decomposed granite were properly mixed rather than the use of the horticultural media as a single medium, which would be advantageous for irrigation management.

The Daebodan was an altar, which held a memorial service for emperors of the Ming dynasty. This alter, which was referred to as Hwangdan, was first constructed in 1704. When the Japanese Invasion of Korea commenced in 1592, Shinjong, the emperor of the Ming dynasty, sent reinforcements to Josun to help. This alter was made to repay Shinjong's kindness. Before this, Song-siyeol(宋時烈), Leader of Noron(老論), made a shrine at Hwayangdong to hold memorial services for Shinjong, and after some time, this developed into a national ceremony. Construction of the Daebodan largely changed the backyard of Changdukgung-palace. However considering the construction process, the meaning of the Daebodan was not a big deal. At first, the optimal place for the Daebodan was selected at the site of a inner icehouse. But the inner icehouse could not be transferred to other site due to the circumstances. After all, the Daebodan was constructed at the site of Byeoldaeyeong(別隊營) which was located in the outside of palace. Most of the stones for the new Daebodan were used ones. And the annexe of Byeoldaeyeong was used for Daebodan without any changes being made. The scale of the construction was not particularly grand. After the construction, Sukjong, who made the Daebodan, showed barely any interest in it. But the conception of the Daebodan was back again in the history by Youngjo. He was also not interested in the Daebodan during his early years of ruling time. However, in the 1740's, he started to become interested in the ceremony of Daebodan, and carried out a large-scale reconstruction of the Daebodan. Jegigo(祭器庫) was rebuilt In 1739. And Jaesil(齋室), staying one night before the ceremonial day, was added in 1745. In 1749, the Daebodan was greatly changed by enshrining Uijong and Taejo, emperors of the Ming dynasty. The shape of alter was changed. Moreover this alter was made by newly quarried stones. And several buildings, Junsachung(典祀廳), Jaesaengchung(宰牲廳) and Akgongchung(樂工廳), were added to the site. In 1762, meritorious retainers were enshrined to the Daebodan. After all the Daebodan became an important part of the backyard of Changdukgung-palace. During the reign of Jungjo, the Daebodan also was an important part of backyard of Changdukgung-palace. But significant changes were not made at that time. The only change was the moving of Kyungbonggak(敬奉閣) in 1799. Afterward the Daebodan remained unchanged. The ceremonies at the Daebodan stopped in 1908. And the Daebodan disappeared into the mist of history.
