시청이동 및 기기이동 이용 판결논리를 토대로 슬링박스를 이용한 TV프로그램의 장소이동 시청의 법적 성격을 공정이용 관점에서 분석하였다. 분석 결과, 소니 판결과 RIAA 판결에 기초하면 장소이동 시청은 비상업적인 사적 이용으로서 공정이용에 해당된다. 냅스터 판결을 적용시킬 경우, 장소이동 시청은 슬링박스 구매자에게만 저작물이 노출되므로 공정이용이지만, 장소이동 기능의 공유는 저작권침해 책임 논란의 소지가 크다. 반면 이용자의 편의성 도모는 저작권 취지에서 벗어난다는 이유로 시간 및 공간이동 기능의 공정이용을 부인한 소니 사건의 2심과 MP3.com 판결에 따르면, 장소이동 시청은 공정이용에 포함되지 않는다. 또한 방송콘텐츠에 미치는 경제적 효과는 플랫폼 확장 차원에서 긍정적이지만, 다양한 단말이 저작권자의 후속시장이 된다는 점에서 부정적이다. 장소이동 시청의 법적 쟁점은 결국 기술혁신과 저작권의 충돌에서 비롯되었다는 점에서 새로운 매체의 법적 책임 분석기준인 "혁신매체의 항변" 을 제안해 본다.

An EPG study was conducted to examine the place of articulation of Korean lenis affricate /c/. Results indicated that the place of articulation of the stop portion /t/ of /c/ was shifted to the place of articulation of the fricative portion /s/ of /c/. Also, we found that the shifting in the place of articulation occurred because of the gap of the place of articulation between /t/ and /s/ (two portions of /c/). From this study, we proposed that the /e/ is articulated at the same place of articulation of /s/ both for its stop portion and its fricative portion. Also, we observed that the place of articulation of /t/ is articulated farther front than that of /s/ and /c/.

In this paper, we implemented a hierarchical encryption system using two-step phase-shifting digital holography(PSDH) technology based on XOR and scramble operations. The proposed encryption system is a system that authenticates access through the issuance of an encryption key for access to individual laboratories, department offices, and universities. In the encryption process, we proposed a double encryption method using XOR and scramble operation with digital technology and two-step phase-shifting digital holography with optical technology. In the two-step PSDH process, an new method of determining the reference wave intensity without measuring it by using random common object image gererated from digital encryption process was also proposed. In the decryption process, the process is performed in the reverse order of encryption process. And only when the various key information used in the encryption process is correct, the encrypted information can be decrypted, so that the user can access the desired place. That is, there is a feature that can hierarchically control the space that can be accessed according to the type of key issued in the proposed encryption system. Through the computer simulation, the feasibility of the proposed hierarchical encryption system was confirmed.

세계의 경제가 글로컬라이제이션(glocalization)이라는 조건 속에서 변화하면서, 국가의 역할은 축소되고, 도시 및 지역의 공간적 역할이 상대적으로 중요해지고 있으며, 관련하여 장소의 역할에 대해 장소마케팅이나 장소브랜딩 등을 통해 지금까지 많은 논의가 이루어져왔다. 하지만, 결과로서의 마케팅전략보다는 과정과 참여를 중요시하는 광의적 의미의 종합적인 '장소만들기'가 중요하다는 의미에서 본 논문은 문화를 기반으로 하는 지역발전이라는 부분에 집중하여 창조적 장소만들기의 전략이 어떤 의미를 갖는지를 재조명하려고 하였다. 구체적으로는 문화콘텐츠산업을 통한 창조적 장소만들기의 한국과 일본사례의 검증을 통하여, 글로컬라이제이션 시대 장소마케팅과 장소브랜딩, 장소만들기의 융합모델을 제시하고, 가치사슬적 특성을 고려하여 자원의 투입과 과정, 산출 등 각 과정의 특성에 집중할 필요가 있음을 밝혔다. 특히, 문화를 기반으로 장소를 해석하고, 지역공동체에서 삶의 질을 개선시키는 목표를 위해 어떻게 선순환구조를 만들것인가 하는 것이 중요하다는 점을 강조하였다.

An Electropalatographic (EPG) study was conducted to investigate the articulatory characteristics which determine the, distinction between the Korean lax fricative [s] and tense fricative [s']. This study also intended to test if an increase in the degree of tensity (lax fricative [s] < tense fricative [s']) induces a decrease in coarticulatory vocalic effects. The results indicated that the increase in the tensity of Korean fricatives is closely related to the increase in the narrowness of the groove width (wider contact at the place of articulation), the forward shifting in the place of articulation, and the longer duration of the constriction (longer maintenance in the manner of articulation). It was also found that coarticulatory vocalic effects on Korean fricatives are affected by Recasens' two rules of constraint (1983) : spatial and temporal constraints.

피조 간섭계의 측정 정밀도를 향상시키기 위해서 광 분할기를 제거한 형태의 피조 간섭계를 구현했다. 단일 모드 광섬유를 구면파 광원으로 사용했고 끝 단을 반사면으로 만들기 위해서 경면 가공했다. 반사면은 적당한 각도로 경사지게 가공되어 있는데 이것은 간섭무늬의 CCD관찰을 용이하게 한다. 경사 단면 광섬유 광원을 이용한 피조 간섭계는 기존의 피조 간섭계에서 구면파를 왜곡시키는 광 분할기를 제거함으로써 측정 정밀도를 향상시킬 수 있었다 또한 동일한 시편의 측정결과를 비교함으로써 기존의 피조 간섭계로부터 개선된 정밀도를 정량적으로 구할 수 있었다. 그리고 경사 단면 광섬유 광원의 구면파정도를 알아보기 위해서 PS/PDI(Phase Shifting/Point Diffraction Interferometer)를 구현함으로써 광원의 구면파 정도를 실험적으로 검증했다.

Construction of power plants and T&D facilities is so difficult because of the civil complaints and the additional cost according to the concerning field conditions. Therefore, various researches and methods have been considered to get solutions in the demand side and energy storage systems have been in the spotlight because of the various functions such as peak shaving, load shifting, and power system stabilizing, and so on. Residential small size batteries are considered in this paper and the economic analysis is carried out to evaluate the reasonable subsidy levels for the deployment of energy storage systems. Various economic parties are considered to find reasonable subsidy level comparing each other, which parties consist of utilities, participants and non-participants in general. The evaluation is based on California Standard Practice Test and the results are able to be used as subsidy guidelines.

Using EPG, the stop and fricative portions of the Korean and English afficates were examined to find out whether the stop and fricative portions of Korean affricates are the same as those of English ones in articulation, as generally assumed in the literature. The English affricate in the word 'choose' is classified as alveopalatal just like the Korean affricate in the word 'cam'. The results of the EPG data showed that Korean affricates were not articulated the same as those in English, especially in the stop portion. In English, the stop portion of 'choose' was quite similar to /t/ as 'tooth', but in Korean, the stop portion of 'cam' was somewhat different from /t/ in 'tam'. More specifically, the stop portion of /t/ in 'tam' was articulated with the contact at the upper teeth and the alveolar ridge, but the stop portion of /t/ in 'cam' was articulated with the contact in the alveopalatal region. This shifting in the place of articulation of the stop portions of the Korean affricate (from dental and alveolar to alveopalatal) can be explained. Unlike English affricates, the stop portions of Korean affricates and the fricative portions of Korean affricates are co-articulated at the same place of articulation.

Axial-ratio (AR) bandwidth enhancement is achieved for a circularly polarized (CP) cylindrical dielectric resonator antenna (DRA) using a wideband hybrid coupler (WHC) combined with dual probe feed. The presented WHC, comprised of a Wilkinson power divider and a wideband $90^{\circ}$ shifter, delivers good characteristics in terms of 3 dB power splitting and consistent $90^{\circ}$ (${\pm}5^{\circ}$) phase shifting over a wide bandwidth. In turn, the proposed CP DRA, for the employment of the WHC, in place of conventional designs, provides a significant enhancement on AR bandwidth and impedance matching. The antenna prototype with the WHC exhibits a 3 dB AR bandwidth of 48.66%, an impedance bandwidth of 52.5% for voltage standing wave ratio (VSWR) ${\leq}2$, and a bandwidth of 44.66% for a gain of no less than 3 dBi. Experiments demonstrate that the proposed WHC is suitable for broadband CP DRA design.

Metrical Phonology has asserted that stress shift does not occur in English compounds because it violates the Continuous Column Constraint. Noun phrases, on the other hand, freely allow for stress shift, whereby the preceding stress moves forward to the preceding heavy syllable. This paper hypothesizes that stress does not shift in compounds as opposed to noun phrases and compares their pitch accentual patterns in a phonetic experiment. More specifically, we examined two-word combinations, noun phrases and compounds, whose boundaries involve stress clash and assured that the preceding words involve a heavy syllable ahead of the stress to guarantee the place for a shifting stress. Depending on where the preceding pitch accent is aligned, stress shift is determined. Results show that stress shift occurs in approximately 47% of the noun phrases and 59% of the compounds; therefore, the hypothesis is not borne out. This suggests that the surface representations derived by phonological rules may not be implemented in real utterance but that phonetic forms may be determined by the phonetic constraints. directly operating on human speech.
