이 논문에서는 "원사" "천문지" <경부>조의 기록을 바탕으로 조선시대 영부에 대해 연구하였다. 조선에서는 1435년과 1440년에 처음으로 대규표와 소규표가 제작되었으며, 이들은 모두 횡량을 가진 진화된 형태의 규표로써 영부를 사용하여 그림자길이를 측정하였다. 영부는 바늘구멍 장치로 Needham et al.에 의해 처음으로 그 모델이 제시되었지만, 구조적 측면에서 "원사"의 원문 내용과 차이를 보이고 있다. 이 연구에서는 조선시대 영부를 "원사"의 경부와 동일했을 것으로 가정하였으며, 이를 토대로 새로운 모델을 제시하였다. 바늘구멍을 통과하는 빛의 경로에 대한 분석을 통해 새 모델의 재원 중 "원사"에 명시되지 않은 영부 밑받침의 높이를 추정하였다.

Bowonsa Temple (普願寺) is located to the north of Gayasan Mountain in Unsan-myeon, Seosan-si, Chungcheongnam-do Province. The cultural properties it enshrines were produced during the late Unified Silla and early Goryeo periods, and include an Iron Seated Buddha. The Japanese Government-General of Korea Museum planned a survey on historical remains in Chungcheongnam-do Province during the early Japanese colonial era, and a field survey was conducted at the Bowonsa Temple site in 1916 (Taishō 5). During this survey, the sculpture of the Iron Seated Buddha (knee: width 212 cm x thickness 167 cm) was found enshrined in a hut. The sculpture was moved to Gyeongbokgung Palace in the following year. However, it is clear that the colossal Iron Seated Buddha was being housed at the Bowonsa Temple site at the start of the Japanese colonial era. This Iron Seated Buddha is presumed to have been produced in 955 by State Preceptor Beopin Tanmun (法印國師 坦文, 900-975). Tanmun was born into an influential family that produced many high officials. He became a leading figure in the Hwaeom (Flower Garland) school of Buddhism under the patronage of King Taejo. He also led Buddhist events at the Goryeo royal court during the reigns of King Hyejong (惠宗, r. 943-945) and King Jeongjong (定宗, r. 945-949). With the emergence of Gyunyeo (均如, 923-973), who was sponsored by Queen Daemok (大穆王后, dates unknown) of the Hwangbo clan (皇甫氏), Tanmun was transferred to Bowonsa Temple far from Kaesong. However, even while there Tanmun strengthened his ties with his supporters under the patronage of the Chungju Yu clan. He appears to have produced this colossal sculpture of Iron Seated Buddha as a prayer for longevity and a happy life for King Gwangjong (光宗, r. 949-975). The inscription on the Stele of State Preceptor Beopin at Bowonsa Temple Site that reads "[I] created a Buddha triad in gold" also suggests the Iron Seated Buddha was produced at Bowonsa Temple. This Iron Seated Buddha is thought to have been enshrined originally in a hall at Building Site No. 3 within the Bowonsa Temple precinct. Since excavations at the temple site have revealed that the temple's main hall was erected in the Joseon period, the Iron Seated Buddha might have been enshrined in a different hall at the time of its creation. It is likely that the sculpture was placed in a hall at Building Site No. 3 since Goryeo-era roof tiles and porcelain have been frequently excavated there and the remains of a square Buddhist altar have survived at the site. At the time of its creation, the Iron Seated Buddha was likely enshrined in a Goryeo-era hall at Building Site No. 3 but was transferred to the main hall during a rebuilding project undertaken at Bowonsa Temple in the Joseon period.

The objective of this study is to examine the structural performance on the Rectangular Steel Tube Column-to-H Beam connections using one-side bolts and T-stub. Although a rectangular steel tube comparing with a H-shaped steel has many advantages and is more efficient, its application is limited due to the lack of experiences and connection details. Existing steel moment connections using the rectangular steel tube are mainly using through plate diaphragms. Its processing of construction is so complicated that it is hard to apply in the field. In this study, the structural performance and the earthquake capacity for T-stub connection with one-side bolts were investigated. And it is performed a comparative analysis of strength, rigidity, total rotation and energy absorption capacity for the various connection details.

고속방사소재는 연신공정이 없이 6,000m/min이상의 고속방사공정만이 있으므로 원가절감이 되고, 빠른 냉각, 높은 변형속도 등으로 섬유의 결정화도, 분자와 결정의 배향 및 모폴로지(morphology) 변화 등의 기계적 및 섬유상의 특성이 종래의 원사와는 다르게 된다. 방사속도가 증가함에 따라 배향도가 증가하면서 결정영역 또한 증가한다. 또한 기존 연신사에 비해 큰 결정크기를 갖는데 방사속도에 에 따른 방사응력의 증가가 응력유도 결정화도를 유발하여 결정크기 및 결정화도를 증가시키고,따라서 고분자의 용융점도를 고온측으로 이동시키는 현상을 나타내게 한다. 즉, 고속방사에 있어서는 연신에 필요한 임계응력 이상의 과도한 응력이 가해짐으로 인해 결정구조가 일반 연신사에 비해 현저히 발달한다는 것을 알 수 있다. 고속방사 원사를 통일한 조건으로 염색하는 경우 기존의 연신사보다 염착량이 많아 농색으로 염색이 가능하고 염착속도도 빠른 특징을 갖는 데이는 고속방사 원사의 비결정 배향이 낮고 느슨한 구조를 갖기 때문에 염료의 침투가 용이한 것으로 해석되고 있다. PET 섬유는 방사 후 형태안정성을 부여하기 위해서 염색 전처리 공정에서 열을 가하게 된다. 이런 과정에서 섬유의 미세구조가 변하게 되는데,특히 고속방사의 경우 섬유 형성과정이 연신사와는 다르므로 열에 의한 구조 변화와 이에 따른 염색성 변화에 대해 검토해 보는 것은 고속방사의 응용면에서 꼭 필요하다. 본 연구에서는 고속방사소재의 가장 단점인 잔류신도, 저수축현상, stiff감을 보완하면서 고속방사소재의 장점인 심색성을 부각시켜 차별화된 복합사 제조기술을 개발하기 위해 그 기술개발이 기초 연구로서 일반 일반 DTY사와 고속방사소재인 HOY사를 이용한 DTY사의 물성 및 염색 특성을 비교분석 하고자 한다.

공정거래위원회(위원장 권오승)는 최근 하도급법 위반사업자에 대한 과징금 부과시 과징금 부과여부 결정 및 과징금액 산정을 위한 세부 기준을 마련하고 지난 8월 22일 하도급법 위반사업자에 대한 과징금 부과기준에 관한 고시를 제정한데 이어 지난 8월 30일부터 시행에 들어갔다. 공정위는 과징금 부과를 위해 종전에는 위원회 사무준칙인 지침을 운용하였으나, 이번 고시 제정을 통해 과징금 부과의 예측가능성, 객관성 및 투명성을 제고하였다. 고시에 따르면 원사업자의 위법행위를 신고한 중소 하도급업체에 거래단절 등 불이익을 주는 보복행위를 하거나 하도급대금·어음할인료·지연이자 등을 지급한 후 이를 회수 또는 납품대금에서 공제하는 탈법행위 등 악성 위법행위에 대해서는 과징금을 부과하기로 했다. 또 위반사업자가 하도급거래시장에서 영향력이 큰 대기업자 이거나 과거 위반전력이 많은 경우로서 부당 하도급대금 결정, 부당감액 등 중대하거나 파급효과가 큰 위반행위를 했을 때도 과징금을 부과하기로 했다. 공정위가 하도급법 위반사업자에 대한 과징금 부과여부의 결정기준과 과징금액 산정방식을 보다 구체화하여 시행함으로써, 법위반의 정도에 상응하는 제재로 인하여 법집행의 실효성이 강화되어 재발방지 효과가 클 것으로 기대된다. 아울러 과징금 부과의 객관성과 투명성을 높이는 한편, 예측가능성을 높임에 따라 대기업 등 원사업자의 자율적인 하도급법 준수 의식을 제고하여 법위반을 사전에 방지함으로써 중소기업의 피해를 예방하는데 크게 기여할 것으로 보여진다.

As the interest and demand in the recycled yarn field has increased rapidly worldwide, domestic companies are also promoting research and development and business on recycled yarn. The chemical and thermal properties of four types of virgin and recycled PET samples from A and B company, which are the leading domestic companies in the recycled polyester yarn business, were confirmed through infrared (FT-IR) spectroscopy and differential scanning calorimetry (DSC). Virgin and recycled PET from two companies were compared. FT-IR spectroscopy revealed the typical spectra of PET for both companies and a different peak at 872 cm-1. DSC confirmed that the melting point and crystallization temperature of recycled PET were lower than those of virgin PET. These results indicate that small amounts of contaminants are an important parameter affecting the thermal properties of recycled PET. In the DSC results after seven repeats of the heating and cooling processes, all four samples showed that a lower melting point, crystallization temperature, and low heat flow intensity increased with increasing number of cycles. The results of melting and crystallization enthalpy also showed similar patterns.

The existing RBAC models are not sufficient for managing delegations or separation of roles. Researches have been done on RBDM(Role Based Delegation Model) that deal with delegating role or permission to other users. In this paper, we divide the delegated roles into two groups: periodic and temporary delegation roles. When a role is delegated, a time period is assigned together, which is used to revoke the permission of delegated role automatically. In our model, the role of monotonic delegation by an original user can be revoked at any time in case of malicious use by the delegated user. The contribution of our model is that the malicious use of delegated role can be prohibited and security vulnerability in the role hierarchy due to role delegations can be alleviated. The proposed model, T RBDM(Time out Based RBDM) is analyzed and compared with the conventional models, such as RBDM0, RBDM1 and PBDM. Our model shows an advantage over other models in terms of security robustness.
