우리는 지금까지 독일어와 한국어 두 언어간의 오류분석을 논의해 왔다. 특히 언어유형학적인 측면에서 몇 가지 오류유형과 분석을 시도했다. 그 결과는 대체로 다음과 같이 요약될 수 있다. 독일어와 한국어가 서로 근본적으로 상반되는 언어현상과 더불어 약간의 공통성을 나타내며 일정한 유형을 나타낸다. 이는 두로 인간의 언어습득장치에 기인된 언어습득의 결정주의(Determinismus)에서 비롯될 것이다. 언어특성/문제의 체계성/규칙성 또는 일관성은 이를 반영한다. 거대한 언어자료 중에 극히 미미한 일부, 즉 언어최소량를 정복함으로써 그 효용성을 극대화할 수 있는 것은 매우 중요한 의미를 지닌다. 이를 연구 이용하는 경우에는 엄청난 효과와 가능성을 기대할 수 있을 것이다. (1) 독일어와 한국어의 학습 및 오류분석에서 가장 핵심적인 것은 언어유형학적으로 드러난 언어특성, 즉 전치성(독일어/영어)과 후치성(한국어)이다. 이를 토대로 형성된 대립적인 면과 공통적인 문제를 체계화하는 것이 역시 오류분석 문제의 관건이다. 또한 독일어가 아직 후치성 언어(한국어(TXV))에서 출발해서 전치성 언어(영어(SVX))로 발전/변화해 가는 과정, 즉 중간단계인 TVX에 머물고 있다는 사실이 중요한 의미를 지닌다. 즉 그들의 대극성과 유사성을 연결하는 실마리로 볼 수 있기 때문이다. (2) 일치(Kongruenz)/상관(Korrelation) 및 반복(Wiederholung) 현상, 그리고 격변화와 인칭변화 현상은 어순문제와 더불어 형태론적 문제를 통해 문법적인 확인수단으로 작용한다. 이들은 대부분 체계적/구조적으로 나타나기 때문에 학습자는 흔히 같은 유형에서 반복적으로 오류를 범하기 마련이다. 이를 극복하기 위해서 언어 유형학적 오류분석을 이해하고 또한 이를 통해 오류를 줄이거나 예방하는 학습이 필요하다. (3) 명사가 한정사구 안에서 성/수/격에 따라 변화하는 것과 동사가 동사구에서 주어의 인칭/수에 따라 인칭변화 하는 것은 우리 한국인에게는 아주 이색적인 현상이다. 이는 양면적인 수식구조에 대한 확인수단 및 원자가에 의한 강력한 형식위주 언어인 독일어와 전위적인 단일 수식구조와 부정형 동사를 특성으로 형성된 핵/최소문 언어간의 필연적인 적응관계 및 결과라고 볼 수 있다. 이 두 가지 유형 역시 언어특성에 따라 도식화/공식화 할 수 있다. (4) 괄호현상, 즉 으뜸머리(Hauptkopf)가 버금머리(Nebenkopf)와 분리하는 것은 우리 한국인에게는 아주 이색적인 언어현상이다. 한국어에는 머리의 이동이 없기 때문이다. 긴 구문에서 버금머리를 잊어버리거나 실수하는 것은 모든 괄호구문에서 예견되는 결과이다. 그러나 이는 정치성과 후치성 언어간의 전이 과정으로 이해될 수 있다. 으뜸머리가 원래의 자리를 박차고 소속 구/문의 앞자리로 도약한 것처럼 느껴지기 때문이다. (5) 전치 및 후치 수식이 유동적으로 작용하는 독일어는 전치 수식만으로 고정된 한국어보다 복잡하지만 균형적인 언어구조이다. 이러한 수식구조에서 한국인은 흔히 형태 및 어순에서, 그리고 번역에서 오류를 범하고 만다. (6) 그러나 가장 중요한 것은 아는 것을 제대로 이용하는 문제이다. 모국어/L2를 자유로이 말하고 쓸 때까지, 즉 언어습득에는 일체이 문법이나 도표/도식을 이용할 필요가 없다는 사실이다. 이는 17세기 서구의 이성주의 철학자들의 한결같은 경고이다. 오늘날 초고속 과학문명에서 더욱 빛을 발하는 것은 당연한 결과이다. 한 언어 속에 들어있는 문법체계를 익혀 가는 것이 곧 언어습득 과정이지만, 이를 달성하는 가능성 내지 첩경은 실제적인 언어자료와 체험이지 결코 문법이나 추상적인 개념적 접근이 아님을 웅변하고 있기 때문이다. 핵심적인 문제는 모국어교육에서도 최대 장점인 대화를 통한 언어연습/대화 기회를 최대한 보장하는 데 있다. 또한 언어간섭 현상을 조장하는 분위기를 막아야 할 것이다. 이러한 의미에서 교수법 개발이 외국어/L2 성공의 관건일 것이다. (7) 언어학습에서 오류를 극복하는 데는 일차적인 실제 상황에 부합하는 대화적인 연습, 그리고 효과적인 언어자료 접촉, 즉 독서와 모방이 중요하다. 이차적이고 직접적인 것은 통사(Syntax) 및 형태론(Morphologie)를 익힐 수 있는 말/문을 끊임없이 익히는 일이다. 이것이 또한 언어최소량을 충족시켜 언어습득에 이르는 첩경이다. 자연 생태적인 모국어 학습 또는 조정 및 제도적인 언어학습에서도 실제상황에 어긋나는 문법적인 체계에 얽매이는 도식 및 도표 위주의 텟스트는 일시적인 기대일 뿐이다. 인간의 언어습득장치를 이해하지 못한 결과이기 때문이다. 문법적인 개념위주 접근은 상당한 설명이 필요해서 절박한 자료와 체험까지 앗아가기 마련이다. 더구나 이를 위해 수준을 무시하고 모국어로 일관하여 벙어리와 문맹을 자초하는 것은 참으로 어리석은 일이다. 지식 정보화 시대 및 세계화 시대에는 무엇보다도 교육 및 언어정책이 국가 발전의 원동력이다. 특히 영어를 비롯한 외국어 학습능력과 학습방법은 매우 중요하다. 학습자에게 말하고 쓰는 기본 능력을 보장하는 것이 급선무이다. 이를 위한 작업의 하나가 바로 언어간의 오류분석일 것이다. 언어의 습득과 활용이 체계적이듯이 오류분석 역시 상당히 체계적이다. 그래서 인간의 언어습득과 언어습득장치를 두고 결정론(Determinismus)이 지배적이다. 이러한 의미에서 언어습득의 3대 요소, 즉 언어습득장치를 구비한 인간으로 태어나고, 해당 언어를 통한 일관된 언어체험/학습으로 언어최소량을 충족해야 한 언어를 정복할 수 있다는 것은 결정적인 사실이다. 학생고객에게 다가서는 책임교육으로 교육개방에 대비하는 일 역시 시대적인 상황이요 또한 결정적인 단계임엔 틀림이 없을 것이다.

The recognitions of geometrical characteristics and occurrence conditions are very important to evaluate the land-slides in natural terrains. In this paper, the geometrical characteristics of landslides are analyzed according to a geo-logical condition in three landslides areas. The three landslides areas are classified to the geological condition. The three landslides areas are Jangheung, Sangju and Pohang. The geology of Jangheung area, Sangju area and Pohang area is gneiss, granite, and the tertiary sedimentary rock, respectively. During a heavy rainfall of $150{\sim}588mm$ in these areas, 1,582 landslides have occurred in 1998. The geometrical characteristics according to the geological condition analyzed from the investigation of these landslides. The frequency of landslide is high exceedingly above 90% of a slope attitude, while the frequency is very low below 70%. The frequency of landslide is high exceedingly between $26^{\circ}$ and $30^{\circ}$ of slope angle, while the frequency is very low below $20^{\circ}$. The size of the landslides is ranged from several tens to several hundreds The length is ranged from 5 m to 300 m, and the width is ranged from 3 m to 50 m. Also, the depth is less than 1 m. Therefore, the landslides in these areas have small width, long length and shallow depth. The type of the landslides is changed from transitional slide at the scarp to debris flow at the low part of slope.

We performed fast pyrolysis of empty fruit bunch (EFB) in the range of temperature from $400{\sim}550^{\circ}C$ and 1.3 s of residence time. The effect of temperature on the yields and physicochemical properties of pyrolytic products were also studied. Elemental and component analysis of EFB showed that the large amount of potassium (ca. 8400 ppm) presents in the feedstock. Thermogravimetric analysis suggested that the potassium in the feedstock catalyzed degradation of cellulose. The yield of bio-oil increased with increasing temperature in the range of temperature from $400{\sim}500^{\circ}C$, while that of gas and biochar decreased and showed monotonous change each with increasing temperature. When the EFB was pyrolyzed at $550^{\circ}C$, the yield of bio-oil and char decreased while that of gas increased. Water content of the bio-oils obtained at different temperatures was 20~30% and their total acid number were less than 100 mg KOH/g oil. Viscosity of the bio-oils was 11 cSt (centistoke), and heating value varied from 15 to 17 MJ/kg. Using GC/MS analysis, 27 chemical compounds which were classified into two groups (cellulose-derived and lignin-derived) were identified. Remarkably the concentration of phenol was approximately 25% based on entire chemical compounds.

This study has focused on the possibility for recycling of tailings from the sangdong tungsten mine as powder (TA) of self-compacting concrete (SCC). The experimental tests for entrapped water ratio were carried out in accordance with the specified method by Okamura. The rheological measurements of cement paste were conducted by using a commercially digital Brookfield viscometer (Model LVDV-II+) equipped with cylindrical spindles, also tests for slump-flow, time required to reach 500 mm of slump flow (sec), time required to flow through V-funnel (sec) and filling height of U-box test (mm) were carried out in accordance with the specified by the Japanese Society of Civil Engineering (JSCE). The results of this study, entrapped water ratio was decreased with increasing replacement of TA. Thickness of pseudo water film was increased, and mean plastic viscosity was decreased with increasing replacement of TA. And slump-flow of SCC was decreased with increasing replacement of TA. But time required to reach 500 mm of slump flow (sec), time required to flow through V-funnel (sec) and filling height of U-box test (mm) were satisfied a prescribed range. The mechanical properties including compressive strength, splitting tensile strength and elastic modulus were checked with the requirements specified by Korean Industrial Standard (KS). The compressive strength of SCC was decreased with increasing replacement of TA, splitting tensile strength and elastic modulus were similar to those of normal concrete.

For evaluating the boar semen quality, sperm motility (MOT) is an important parameter because the movement of spermatozoa indicates active metabolism, membrane integrity and fertilizing capacity. Estrogen receptors 2(ESR2) is involved in estrogen related apoptosis in cell cycle spermatogenesis, but their functions have not been confirmed in pig until now. Therefore, this study was conducted to analyze their association with sperm motility and kinematic characteristics. DNA samples from 105 Duroc pigs with records of semen motility and kinematic characteristics [Total motile spermatozoa (MOT), Curvilinear velocity(VCL), Straight-line velocity(VSL), the ratio between VSL and VCL(LIN), Amplitude of Lateral Head displacement(ALH)] were analyzed. A SNP in coding region of ESR2 g.35547A > G in exon 5 was associated with MOT (p < 0.05) in Duroc population. Therefore, we suggest that the porcine ESR2 gene may be used as a molecular marker for Duroc boar semen quality, although its functional effects were not defined yet. These results might shed new light on the roles of ESR2 in spermatogenesis as candidate gene for boar fertility, but still the lack of association across populations should be considered.

A method to calculate stability limits is investigated to predict the characteristics of high-frequency combustion instability in liquid-propellant rocket engine. It is based on the theory of linear stability analysis proposed in previous works and useful to predict combustion stability at the beginning stage of engine development. The system of equations governing reactive flow in combustor has the simplified and linearized forms. The overall equation expressing stability limits is adopted. The procedures to evaluate quantitatively each term included in the equation are proposed. The thermo-chemical properties and flow variables required in the evaluation can be obtained from calculation of thermodynamic equilibrium, CFD results, and experimental test data. Based on the existent data, stability limits are calculated with actual rocket engine (KSR-III rocket engine). The present calculations show the reasonable stability limits in a quantitative manner and the stability characteristics of the engine are discussed. The prediction from linear stability analysis could be serve as the first approximation to the true prediction.

The present study has been carried out to analyze the flow characteristics with geometric shape and control conditions in subsea by-pass valve. The function of by-pass valve is to prevent reverse flow. In this study, the static analysis has been perform for analyzing fluid flow in open state. In order to consider the turbulent effect, the standard ${\kappa}-{\varepsilon}$ model was used. A variety of parametric studies, such as by-pass valve type or size, volume flow rate, leakage hole size, leakage hole position, block type, block shape, were performed. The pressure difference across the valve in the model broadened the flow channel cross-sectional area was greater than the base model for the same operating conditions. As the pipe diameter in the block decreases the pressure difference is greatly increased. The pressure difference according to block shape such as edge type and round was almost negligible. For the same Reynolds number the pressure difference was little changed according to the size of the valve.

K-SGICs(synthetic graphite intercalation compounds) were synthesized in a modified two-bulb pyrex tube. The pressure in the two-bulb tube was maintained at approximately $10^{-3}$ torr for the reaction of potassium and graphite. Deintercalation process of the K-SGlCs obtained by the modified method was heat-treated by keeping in liquid paraffin between $25^{\circ}C$ and $1400^{\circ}C$. The thermal stability and the temperature dependence of the K-SGICs were characterized using differential scanning calorimeter(DSC) analyzer. Enthalpy and entropy for K-SGIC formations were calculated by confirming the deintercalation and thermodynamic exothermic reactions depending on the various temperatures. The structure changes and thermal stability of K-SGICs during the deintercalation reaction of potassium ions and the interlayer spaces of the synthetic graphite were identified by X-ray diffraction(XRD).
