This paper presents an incremental delta-sigma analog-to-digital converter (ADC) for a single-electrode capacitive touch sensor. The second-order cascade of integrators with distributed feedback (CIFB) delta-sigma modulator with 1-bit quantization was fabricated by a $0.18-{\mu}m$ CMOS process. In order to achieve a wide input range in this incremental delta-sigma analog-to-digital converter, the shielding signal and the digitally controlled offset capacitors are used in front of a converter. This circuit operated at a supply voltage of 2.6 V to 3.7 V, and is suitable for single-electrode capacitive touch sensor for ${\pm}10-pF$ input range with sub-fF resolution.

This study is to analyse the impacts of screen quota in the screen industry and suggests policy implications. To achieve the purpose of this study, we reviewed the theoretical base and history of screen quota, and analyze the share ratio of domestic films and the impacts of screen quota on the actors concerned it. The screen quota was introduced for the purpose of cultural diversity and the protection of screen industry. But it constrained consumer's choice and owner's property. This study suggested policy implications bases the analytical results.

This study has a main purpose that closely examines the structural relationship among relationship marketing, and relationship quality and re-use intention of adult ballet academy In order to achieve it, the sample from customer of ballet academy were accumulated by using convenience sampling that chose ballet academy in Seoul. The samples were 400 people. and we excluded unsuitable sheet like that were decided as un-trustful one and an omission and unclear. So the final samples were 361 people. On the basis of that, The statistical techniques, spss 24.0 and amos 24.0 program have been used for the analysis as per research purpose. The research has drawn the following conclusions, based on the above mentioned research method and its procedures: First, relationship marketing influences customer satisfaction. Second, relationship marketing influences customer trust. Third, customer satisfaction influences re-use intention. Fourth, customer trust influences re-use intention.
복잡계 리더십이 구성원 민첩성에 미치는 영향: 개인적 양면성 매개효과와 참여적 리더십과 상호작용 공정성의 조절효과

본 연구는 복잡계 리더십 (complexity leadership) 이 구성원 민첩성 (employee ’ s agility) 에 영향을 미치는 직접효과와 개인적 양면성 (individual ambidexterity)을 경유하는 간접효과를 규명하고, 복잡계 리더십과 개인적 양면성 간 참여적 리더십의 조절효과와 개인적 양면성과 구성원 민첩성 간 상호작용 공정성의 조절효과를 밝히고자 하였다. 본 연구에서는 자기보고형 설문방식의 측정으로 인해 나타날 수 있는 동일방법편의 (common method bias) 를 최소화하기 위해 종속변수는 시차를 두고 별도로 측정하였고, 직무상황에서 정서 상태를 표현해주는 긍정정서와 부정정서 및 상사와의 근무기간을 통제변수로 채택하였다. 국내 300 인 이상 규모의 다양한 업종의 기업에 근무하는 직장인들로부터 획득된 303부의 설문지가 분석에 사용되었다. 연구 결과 첫째, 복잡계 리더십과 구성원 민첩성 간의 직접효과는 유의하지 않은 것으로 나타났다. 둘째, 복잡계 리더십은 개인적 양면성을 매개로 하여 구성원의 민첩성을 촉진하는 것을 확인하였다. 셋째, 리더의 참여적 리더십 발휘가 복잡계 리더십이 개인적 양면성에 미치는 효과를 강화하는 것으로 확인되었다. 넷째 개인적 양면성과 구성원 민첩성의 관계에서 상호작용 공정성의 조절효과가 나타났다. 본 연구는 구성원 민첩성을 촉진하는 메커니즘을 규명하였다. 즉, 조직 민첩성을 위해 가장 기본이 되는 구성원 민첩성이 어떠한 리더십 및 구성원 개인의 역량에 의해 촉진되는지를 검증하였다. 특히 국내에서는 실증연구가 부족한 복잡계 리더십을 새롭게 제시하여 리더십 연구의 확장 가능성을 보여준데 의의가 있다. 또한 리더가 문제해결 과정을 공유하는 참여적 리더십과 의사결정 과정에서 리더가 보여주는 행위에 대한 구성원의 인식인 상호작용 공정성의 조절효과를 각각 검증함으로써 기존 선행연구와는 다른 새로운 시사점을 제시하였다.

On July 23th, 2009, the newly-revised copyright law was reflected the free trade agreement which occurred between the United States and the Republic of Korea. The agreement is expected to have positive effects such as competition as well as the social efficiency in the field of intellectual property. Nevertheless, Korean government should pay much costs, Therefore, we should minimize the cost in a short run and maximize the benefits we could obtain out of the agreement in a long run. However, we are not prepared to improve economic value of the intellectual property rights. Specifically, it should be noted that the aspects of law execution to protect not only the intellectual property rights. If we manage to get the utmost out of the agreement, we could be going through the transition from a consumer nation of intellectual properties to a producer nation.

Farmers’ fertilization management, particularly application of livestock manure and compost which are typically enriched with heavy isotopes of carbon (C) and nitrogen (N) as well as copper (Cu) and zinc (Zn), may change these chemical variables in agricultural soils. This study was conducted to investigate variations in the concentrations of C, N, Cu and Zn, and stable C (δ<sup>13</sup>C) and N (δ<sup>15</sup>N) isotope ratios of paddy, upland, and orchard soils that received different rate of manure and compost. Forest (pine and oak) soils were additionally included as background soils. The elemental and isotopic compositions of agricultural inputs (including synthetic fertilizer, rice straw, and livestock feed, manure, and compost) and forest litter layer were also analyzed. There was no systematic variation in soil C and N concentrations among different land-use types. However, the δ<sup>13</sup>C, δ<sup>15</sup>N, and the concentrations of Cu and Zn of agricultural soils were higher than those of forest soils, reflecting repeated manure and compost applications in agricultural soils. Among agricultural soils, orchard soils which received higher rates of manure and compost had higher δ<sup>13</sup>C (-24.2‰), δ15N (+10.6‰), and the concentrations of Cu (16.3 mg kg<sup>-1</sup>) and Zn (61.7 mg kg<sup>-1</sup>), compared to paddy (-28.0‰, +4. 9‰, 10.3 mg kg<sup>-1</sup>, and 41.9 mg kg<sup>-1</sup> for δ<sup>13</sup>C, δ<sup>15</sup>N, and Cu and Zn concentrations, respectively) and upland soils (-25.4‰, +9.6‰, 11.8 mg kg<sup>-1</sup>, and 41.7 mg kg<sup>-1</sup>, respectively). Such differences in the isotopic and metal compositions among agricultural soils were also found for soil solutions extracted with K<sub>2</sub>SO<sub>4</sub>. Our study suggests that farmers’ fertilization management such as repeated application of livestock manure and compost may change δ<sup>13</sup>C, δ<sup>15</sup>N, and Cu and Zn concentrations of agricultural soils. However, the potential effects of other compounding factors that co-vary with land-use type such as parent materials and topography need to be further evaluated.
