본 연구는 지리교과를 통한 시민성 교육의 가능성을 탐색하기 위한 것으로서 '시민성'과 '시민성의 공간' 에 대한 내재적 정당화에 관한 논의이다. Peters의 지식의 형식과 입문으로서의 교육관에 따라 지리적 지식의 형식을 검토하여 시민성을 내재적으로 정당화하였다. 지리학은 탈실증주의 패러다임의 언어와 이데올로기의 도입을 통해 기존의 '공간' 중심에서 '인간'과 '사회'에 더욱 관심을 가지는 방향으로 나아가고 있는데 이는 다름아닌 시민성의 공간으로의 전환을 의미한다. 즉, 사회공간이론을 통해 가치중립적인 물리적 공간 개념을 거부하고, 가치내재적인 '시민성의 공간'으로 전환을 모색하고 있다. 이러한 지리적 지식의 형식의 변화가 지리교과의 내용지식의 변화를 주도한다고 볼 때, 시민성은 내재적으로 정당화될 수 있다. 이와 같이 지리교과의 내용지식으로서의 시민성은 사회과 교육목적을 그대로 수용하는 외재적 정당화가 아니라, 지리적 지식의 형식을 통해 내재적으로 정당화될 때 의미를 지닌다. 그리고 시민성 공간에 토대한 시민성이라는 가치와 신념으로의 입문으로서의 지리교육은 학생들로 하여금 어떤 목적지에 도달하도록 하는 것이 아니라, 다른 관점을 가지고 나아가도록 해야 한다는 것을 의미한다.

We present results of our investigation of the radio intrinsic brightness temperatures of compact radio jets. The intrinsic brightness temperatures of about 100 compact radio jets at 2, 5, 8, 15, and 86 GHz are estimated based on large VLBI surveys conducted in 2001-2003 (or in 1996 for the 5 GHz sample). The multi-frequency intrinsic brightness temperatures of the sample of jets are determined by a statistical method relating the observed brightness temperatures with the maximal apparent jet speeds, assuming one representative intrinsic brightness temperature for a sample of jets at each observing frequency. By investigating the observed brightness temperatures at 15 GHz in multiple epochs, we find that the determination of the intrinsic brightness temperature for our sample is affected by the flux density variability of individual jets at time scales of a few years. This implies that it is important to use contemporaneous VLBI observations for the multi-frequency analysis of intrinsic brightness temperatures. Since our analysis is based on the VLBI observations conducted in 2001-2003, the results are not strongly affected by the flux density variability. We find that the intrinsic brightness temperature $T_0$ increases as $T_0{\propto}{\nu}^{\xi}_{obs}$ with ${\xi}=0.7$ below a critical frequency ${\nu}_c{\approx}9GHz$ where the energy loss begins to dominate the emission. Above ${\nu}_c$, $T_0$ decreases with ${\xi}=-1.2$, supporting the decelerating jet model or particle cascade model. We also find that the peak value of $T_0{\approx}3.4{\times}10^{10}$ K is close to the equipartition temperature, implying that the VLBI cores observable at 2-86 GHz may be representing jet regions where the magnetic field energy dominates the total energy in jets.

Highly viscous biopolymer from alkali-tolerant Bacillus sp. was purified and its solution properties were investigated. The intrinsic viscosities for crude biopolymer and biopolymers purified by dialysis or CPC(cetylpyridinium chloride) treatment were 58.24, 73.60 and 42.18 dL/g, respectively. The intrinsic viscosity of biopolymer showed the maximum value at the neutral pH but it was decreased remarkably at the alkaline or acidic pH. Biopolymer exhibited the property of polyelectrolyte, showing the sharp decrease of intrinsic viscosity by the addition of NaCl. Intrinsic viscosity of dilute solution at the low NaCl concentration was exponentially dependent on temperature and its temperature dependency was increased with NaCl concentrations. The chain stiffness, coil overlap parameter, and critical concentration were 0.09, 5.25 and 0.07g/dL, respectively. Temperature dependency on intrinsic viscosity of biopolymer solution was different each other at $45^{\circ}C$. Flow activation energies at temperatures above $45^{\circ}C$ were constant, while those at temperatures below $45^{\circ}C$ increased with increase of added NaCl concentration.

The activated partial thromboplastin time (APTT) is used primarily to evaluate coagulation abnormalities in the intrinsic pathway. The proper specimen is very important factor for precise results of blood coagulation analysis. The objective of this study was to get to the conclusion of whether to analyze again and to collect blood sample over again when APTT result shows below the reference value. We evaluated 126 samples showing a value below 20.0 sec at ATPT result, which consist of 48 males and 78 females candidates during night duty from March 2012 to December 2012. Average comparisons of APTT result between first and retested analysis among study subjects were significantly different in male samples. APTT results comparison of recollected subjects among clotted samples were also significantly different with both sexes (p<0.000). We suggest that we should carefully check the samples to get accurate results and collect samples again in case of only obtaining improper samples; even though the APTT result show below reference value.

The aim of this study is twofold. First, this study aimed to explore how Korean university students' English learning motivation is related to their English listening proficiency and study time. Second, it attempted to interpret the English learning motivation linking the two different motivation theories: self-determination theory and L2 motivational self system. The constructs of the students' L2 learning motivation were investigated with the data obtained through the questionnaire from 122 sophomore students. A factor analysis was conducted to extract the major factors of motivation. As a result, 6 factors were extracted: Intrinsic Pleasure, Identified Value Regulation, Intrinsic Accomplishment, Introjected Regulation, External Regulation, and Identified Regulation. The Interrelatedness among the assessment results on the L2 listening proficiency (pre and post test), listening study time, and motivation factors was measured by correlation coefficients. The statistical results indicated that pre-test scores were significantly related to Identified Regulation and Identified Value Regulation toward English learning, and post-test results had significant correlation with Intrinsic Accomplishment and Identified Regulation. However, no motivation subtypes showed statistical association with the students' listening study time. The results were attempted to be interpreted both under L2 motivational self system and self-determination framework to better illuminate the motivation theory with more explanatory power.

Purpose: This study was tried to investigate a structural relationship among key impacting factors and usage in SNS of government institutions. It was designed to research the processing property of SNS, the emotional property of SNS, and the service property of SNS for the SNS usage. Based on the research framework from the relationships among intrinsic SNS characteristics, social psychological characteristics, and the attitude of government institutions' SNS, the empirical research model and the hypotheses were established. Design/methodology/approach: Data for empirical study were collected from 453 of total distributed 500 by the structured questionnaire survey with SNS users of government institutions. The analysis was performed from effective 432 data, and the sample was mainly consisted of men, the thirty-old, and salesmen. Findings: The results showed that the emotional and service properties in intrinsic characteristics of SNS have a significantly positive effect to the value perception and the security variable in social psychological characteristics has a significant positive effects to the trust. Finally, the value perception has positive effects on both trust and use intention of government institutions' SNS. Meaning of these results is that intrinsic SNS characteristics, social psychological characteristics, and the attitude of government institutions' SNS have a significant effect on SNS usage.

통일 및 팔달쌀 전분의 이화학적 성질을 살펴본 바, 전분의 물결합능력, blue value 및 아밀로스 함량에 서로 차이가 없었다. 팔달 전분은 통일 전분에 비해 팽화력이 높았다. 아밀로그라프에 의한 두전분의 차이는 볼 수 없었으나 통일이 팔달보다 $50^{\circ}C$로 냉각시 점도가 다소 높았다. 또한 통일 아밀로스의 intrinsic viscosity는 팔달 아밀로스보다 높았으나 아밀로펙틴은 두 전분모두 비슷한 값을 보였다. 전분 gel의 retrogradation 속도는 $21^{\circ}C$에서 통일이 팔달보다 다소 빨랐다.

Everyone lives in a home. We pursue happiness and the meaning of life through home life or family life. Home life, therefore, has an important meaning in the whole life, But home life can be sustained only through housework and wage labor. All human activities can be divided into two kinds of activities. The one has intrinsic value, the other has extrinsic value. Housework belongs to the activity with intrinsic value, but wage labor belongs to the activity with extrinsic value. In view of home life, housework has primary meaning, and wage labor has subsidiary meaning. In other words, wage labor is only means of home life. We mush not forget that important fact. But we cannot help thinking that nowadays people consider wage labor itself as an aim of life. It is said that we are achieving self-actualization through wage labor, but it is not ture. To tell the truth, most of us are experiencing self-alienation in job. We must recover the legitimate relation between housework and wage labor. Wage labor is means of home life, therefore it is on the extension line of housework. If we achieve happiness through home life, we must recognize that wage labor is only means of home life, not an end in itself.

Image matching is fundamental process to identify conjugate points on the stereo images. However, standard methods or general solutions for matching problem have not been found yet, in spite of long history. Quality of the matching basically depends on uniqueness of the matching entity and robustness of the algorithm. In this study, conjugate points were extracted by implementing interest operator, then area based matching method was applied to the topographical characteristics of the gray value as the matching entities. The matching entities were utilized based on the concept of the intrinsic image.
