이 글의 목적은 요한 제바스티안 바흐와 그의 교회 칸타타 안에 흐르는 ‘당대’ 루터교의 신학 언어를 읽어내고, 이것이 의미하는 바를 역시 신학적인 언어로 해석하는 것이다. 이를 위해 바흐 의 ≪칸타타 75번≫, ‘주린 자는 먹을지어다’(Die Elenden sollen essen)를 분석한다. 이 작품 안 에 담긴 루터교의 교리와 메시지는 어떤 것인지, 그리고 이들은 어떤 신학적 언어로 기록되어 있 는지 파악해 나간다. 이러한 논의를 통해 주목하고자 하는 것은 ≪칸타타 75번≫에서 발견되는 두 개의 교리, 즉, ‘칭의’와 ‘십자가 신학’이고 이것의 신학적인 의미이다. 마지막으로 이 글은 루터 교를 상징하는 두 교리가 ≪칸타타 75번≫에 깊숙이 뿌리내리고 있다는 사실을 역설하면서, 이러 한 주장이 내포하는 바에 대해 질문한다.

사회적 기업은 효율과 경쟁 중심의 자본주의 시장경제 속에서 발생하는 양극 화, 고령화 사회, 환경문제 등 다양한 사회 문제를 해결하기 위하여 등장하였 다. 특히, 세계적인 금융위기가 지속되면서 전통적인 사회적 기업인 협동조 합이 대안 모델로 주목받고 있다. 하지만, 이러한 협동조합이 자본주의 시장 경제 속에서 경쟁력을 갖춘 사회적 기업으로 지속가능할 것인가에 대해서는 다소 의문이 제기되고 있다. 그 이유는 협동조합이 사업체임과 동시에 사회 적 목적을 실현하는 단체로서의 이중성을 갖고 있으며, 주식회사와 다른 고 유한 조직적 특성이 있음에도 불구하고 이러한 특성이 제대로 반영되지 못하 고 있기 때문이라고 한다. 이에 이러한 특성을 반영하고 그 기능과 역할을 제대로 수행할 새로운 형태 의 사회적 기업을 요청하게 되었다. 따라서 본 논문은 사회적 목적과 가치를 실현하며 정부의 지원 없이도 독자적으로 지속 가능한 운영을 할 수 있는 새 로운 형태의 사회적 기업으로 미국의 L3C, 인증 B콥 기업, BC를 검토하고자 하였다. 이러한 제도는 유럽과 달리 국가 내지 정부 중심이 아닌 기업 중심으 로 기본적으로 영리추구형 사회적 기업이며, 독자적 형태의 존립 기반과 정 부의 지배를 받지 않는 자율적인 운영을 하는 기업이기 때문이다. 생각건대, 사회적 기업으로서 기능과 역할을 제대로 수행하기 위해서는 유럽식의 사회 적 기업 모델은 한계가 있다고 생각된다. 따라서 위에서 요청하는 역할과 기 능을 실질적이고 지속적으로 수행할 수 있는 미국의 새로운 형태인 사회적 기업에 대한 검토를 하고, 이를 도입할 경우 현행 법제도상 어떤 문제점을 검 토할 것인지에 대하여 살펴보았다.

고문읽기와 쓰기는 우수한 중국 전통 문화의 계승과 발전을 위한 기초 능력이다. 현재 고문 교육은 학습 효율이 낮고, 문턱이 높으며, 목적성이 부족하다는 세 가지 문제점이 존재한다. 고문읽기와 고문자에 대한 두려움은 많은 청소년들이 맞닥뜨리고 있는 실제 문제이다. 본 연구는 고대 중국어 교육의 특징과 실제에 근거하여 대규모 고적 코퍼스의 통계 작업을 통해 1,000개의 한자를 선정하였다. 한자의 자형, 자음, 자의, 용자 네 가지 측면에서 각 등급별 기준을 설정하고, 한자 학습의 우선순위를 반영하여 ｢고적한자등급자표古籍汉字分级字表｣를 개발하였다. 이 표 에는 1급 105자, 2급 340자, 3급 555자를 수록되어 있다. 청소년에게 고문 학습을 위해 한자학습 자료를 제공하는 것은 고적 한자의 점진적 학습을 도울 뿐 아니라 청소년이 가지고 있는 고문 학습에 대한 부담감을 줄여주고 고문 읽기 능력을 향상시켜 줄 것이다. 더 나아가 중국의 우수한 전통 문화를 계승하고 발전시키는 데 도움을 줄 것으로 기대한다.

ZnO/Cu/ZnO (ZCZ) thin films were deposited at room temperature on a glass substrate using direct current (DC) and radio frequency (RF, 13.56 MHz) magnetron sputtering and then the effect of post-deposition electron irradiation on the structural, optical, electrical and transparent heater properties of the films were considered. ZCZ films that were electron beam irradiated at 500 eV showed an increase in the grain sizes of their ZnO(102) and (201) planes to 15.17 nm and 11.51 nm, respectively, from grain sizes of 13.50 nm and 10.60 nm observed in the as deposited films. In addition, the film’s optical and electrical properties also depended on the electron irradiation energies. The highest opto-electrical performance was observed in films electron irradiated at 500 eV. In a heat radiation test, when a bias voltage of 18 V was applied to the film that had been electron irradiated at 500 eV, its steady state temperature was about 90.5 °C. In a repetition test, it reached the steady state temperature within 60 s at all bias voltages.

As the demand for p-type semiconductors increases, much effort is being put into developing new p-type materials. This demand has led to the development of novel new p-type semiconductors that go beyond existing p-type semiconductors. Copper iodide (CuI) has recently received much attention due to its wide band gap, excellent optical and electrical properties, and low temperature synthesis. However, there are limits to its use as a semiconductor material for thin film transistor devices due to the uncontrolled generation of copper vacancies and excessive hole doping. In this work, p-type CuI semiconductors were fabricated using the chemical vapor deposition (CVD) process for thin-film transistor (TFT) applications. The vacuum process has advantages over conventional solution processes, including conformal coating, large area uniformity, easy thickness control and so on. CuI thin films were fabricated at various deposition temperatures from 150 to 250 °C The surface roughness root mean square (RMS) value, which is related to carrier transport, decreases with increasing deposition temperature. Hall effect measurements showed that all fabricated CuI films had p-type behavior and that the Hall mobility decreased with increasing deposition temperature. The CuI TFTs showed no clear on/off because of the high concentration of carriers. By adopting a Zn capping layer, carrier concentrations decreased, leading to clear on and off behavior. Finally, stability tests of the PBS and NBS showed a threshold voltage shift within ±1 V.

The purpose of this study was to analyze microstructural changes and evaluate the mechanical properties of TWIP steel subjected to variations in heat treatment, in order to identify optimal process conditions for enhancing the performance of TWIP steel. For this purpose, a homogenization heat treatment was conducted at 1,200 °C for 2 h, followed by hot rolling at temperature exceeding 1,100 °C and cold rolling. Annealing heat treatment is achieved using a muffle furnace in the range of 600 °C to 1,000 °C. The microstructure characterization was performed with an optical microscope and X-ray diffraction. Mechanical properties are evaluated using micro Vickers hardness, tensile test, and ECO index (UTS × Elongation). The specimens annealed at 900 °C and 1,000 °C experienced a significant decrease in hardness and strength due to decarburization. Consequently, the decarburization phenomenon is closely related to the heat treatment process and mechanical properties of TWIP steel, and the effect of the microstructure change during annealing heat treatment.

Recently, the electron transport layer (ETL) has become one of the key components for high-performance perovskite solar cell (PSC). This study is motivated by the nonreproducible performance of ETL made of spin coated SnO2 applied to a PSC. We made a comparative study between tin oxide deposited by atomic layer deposition (ALD) or spin coating to be used as an ETL in N-I-P PSC. 15 nm-thick Tin oxide thin films were deposited by ALD using tetrakisdimethylanmiotin (TDMASn) and using reactant ozone at 120 °C. PSC using ALD SnO2 as ETL showed a maximum efficiency of 18.97 %, and PSC using spin coated SnO2 showed a maximum efficiency of 18.46 %. This is because the short circuit current (Jsc) of PSC using the ALD SnO2 layer was 0.75 mA/cm2 higher than that of the spin coated SnO2. This result can be attributed to the fact that the electron transfer distance from the perovskite is constant due to the thickness uniformity of ALD SnO2. Therefore ALD SnO2 is a candidate as a ETL for use in PSC vacuum deposition.

The effects of La3+ substitution for Sr2+-site on the crystal structure and the dielectric properties of (Ba0.7Sr0.3-3x/2Lax) (Ti0.9Zr0.1)O3 (BSLTZ) (0.005 ≤ x ≤ 0.02) ceramics were investigated. The structural characteristics of the BSLTZ ceramics were quantitatively evaluated using the Rietveld refinement method from X-ray diffraction (XRD) data. For the specimens sintered at 1,550 °C for 6 h, a single phase with a perovskite structure and homogeneous microstructure were observed for the entire range of compositions. With increasing La3+ substitution (x), the unit cell volume decreased because the ionic size of La3+ (1.36 Å) ions is smaller than that of Sr2+ (1.44 Å) ions. With increasing La3+ substitution (x), the tetragonal phase fraction increased due to the A-site cation size mismatch effect. Dielectric constant (εr) increased with the La3+ substitution (x) due to the increase in tetragonality (c/a) and the average B-site bond valence of the ABO3 perovskite. The BSLTZ ceramics showed a higher dielectric loss due to the smaller grain size than that of (Ba0.7Sr0.3)(Ti0.9Zr0.1)O3 ceramics. BSLTZ (x = 0.02) ceramics met the X7R specification proposed by the Electronic Industries Association (EIA).

In order to develop catechin patches for skin regeneration at wound sites, patches with varying concentrations of catechin and chitosan were manufactured. An optimal composition ratio was determined by adjusting the drug release rate and amount, to maximize efficiency. The catechin used in this study was extracted from green tea leaves using a solvent/ultrasonication method, and its characteristics were confirmed through Fourier transform-infrared spectroscopy (FT-IR) and high-performance liquid chromatography (HPLC) analyses. Patches were prepared with different concentrations of catechin and chitosan, and various properties were analyzed using techniques such as FT-IR, water contact angle analysis, and UV-Vis spectroscopy. It was observed that as the chitosan concentration increased, the release of catechin slowed down or almost ceased. A patch manufactured with 1.5 mg/cm2 of catechin at a 1 % chitosan concentration exhibited a high initial release rate over 24 h and demonstrated cellular biocompatibility. Consequently, these patches, with tailored release characteristics based on the concentrations of chitosan and catechin, hold promise for use as drug delivery systems in wound healing applications.

Single-atom Pd clusters anchored on t-BaTiO3 material was synthesized using hydrothermal and ultrasonic methods for the effective piezoelectric catalytic degradation of pollutants using vibration energy. XRD patterns of BaTiO3 loaded with monoatomic Pd were obtained before and after calcining, and showed typical cubic-phase BTO. TEM and HAADF-STEM images indicated single-atom Pd clusters were successfully introduced into the BaTiO3. The piezoelectric current density of the prepared Pd-BaTiO3 binary composite was significantly higher than that of the pristine BaTiO3. Under mechanical vibration, the nanomaterial exhibited a tetracycline decomposition rate of ~95 % within 7 h, which is much higher than the degradation rate of 56.7 % observed with pure BaTiO3. Many of the piezo-induced electrons escaped to the Pd-doped BaTiO3 interface because of Pd’s excellent conductivity. Single-atom Pd clusters help promote the separation of the piezo-induced electrons, thereby achieving synergistic catalysis. This work demonstrates the feasibility of combining ultrasonic technology with the piezoelectric effect and provides a promising strategy for the development of ultrasonic and piezoelectric materials.

Changes in the microstructure and mechanical properties of as-roll-bonded AA6061/AA5052/AA1050 threelayered sheet with increasing annealing temperature were investigated in detail. The commercial AA6061, AA5052 and AA1050 sheets with 2 mm thickness were roll-bonded by multi-pass rolling at ambient temperature. The roll-bonded Al sheets were then annealed for 1 h at various temperatures from 200 to 400 °C. The specimens annealed up to 250 °C showed a typical deformation structure where the grains are elongated in the rolling direction in all regions. However, after annealing at 300 °C, while AA6061 and AA1050 regions still retained the deformation structure, but AA5052 region changed into complete recrystallization. For all the annealed materials, the fraction of high angle grain boundaries was lower than that of low angle grain boundaries. In addition, while the rolling texture of the {110}<112> and {123}<634> components strongly developed in the AA6061 and AA1050 regions, in the AA5052 region the recrystallization texture of the {100}<001> component developed. After annealing at 350 °C the recrystallization texture developed in all regions. The as-rolled material exhibited a relatively high tensile strength of 282 MPa and elongation of 18 %. However, the tensile strength decreased and the elongation increased gradually with the increase in annealing temperature. The changes in mechanical properties with increasing annealing temperature were compared with those of other three-layered Al sheets fabricated in previous studies.

Purpose: This study utilizes a phenomenological research method to understand the nature of role adaptation experience of PA nurses. Methods: This was a qualitative study that applied Colaizzi’s phenomenological research method to understand the nature of role adaptation experience of PA nurses. The study participants were thirteen PA nurses (three men and ten women) with over five years of experience. For data collection, individual in-depth interviews were conducted, each about 50 to 90 minutes long. Individual interviews were conducted once or twice. Colaizzi’s method was used to analyze data. Results: The result of this study had 11 clusters of themes and 4 major themes were derived from the analysis: “parallel lines of conflict,”“anxiety about unclear future,”“disorganization of identity,”and “my own way to learn about myself.”These four major themes are structured chronologically to the extent possible but are not mechanically segmented based on time. Conclusion: This study recognizes the seriousness of PA nurses’problems in the absence of research on PA nurses’role adaptation experience and recommends that appropriate research is necessary. Standardized work guidelines and positive awareness of the role of PA nurses are necessary and are supported by PA nurses to establish their position as professionals.

Purpose: This study aimed to investigate the perception of visiting hospice services to end-of-life patients at home. Methods: Individual in-depth interviews and qualitative content analysis were used for data collection and analysis, respectively. The study’s participants were 15 end-of-life patients receiving visiting hospice services at home. Results: Four themes emerged from nine subthemes, which were categorized from 26 condensed meaning units by interpreting underlying meanings. The four themes were “service with value started by chance”, “service that fills the care gap”, “service that the vulnerable group can rely on”, and “service that is insufficient to medical support”. Conclusion: Based on these results, it is suggested that policy support is needed to develop and apply a community-based hospice service model that connects hospitals and homes.

Purpose: This study aimed to explore the practical experience of nursing graduates through a clinical practicum alternative program during the COVID-19 pandemic. Methods: Participants in this study comprised sixteen students who had gone through clinical field practice and clinical alternative programs during 4 semesters at nursing college. Data were collected through individual in-depth interviews and analyzed via the phenomenological research method developed by Colaizzi. Results: From the meaningful statements offered by the participants, six theme clusters emerged: (a) interest in new experiences, (b) practice that doesn’t feel like practice, (c) limits on yourself, (d) ambivalence about alternative programs, (e) longing for vivid clinical settings, and (f) choice in an unavoidable situation. Conclusion: This study provides a profound understanding of the practical experiences of nursing students during the COVID-19 pandemic situation about the clinical practicum alternative program. Based on this study, it is necessary to determine how students who have participated in the implementation of the clinical practice alternative program are adapting to the actual field as nurses. It is also necessary to develop various programs that reflect the needs of students and utilize technologies such as virtual reality, augmented reality, and metaverse along with current teaching methods.

The themes included: “Mandatory or optional experience of wearing a mask unrelated to COVID-19”, “Mandatory KF94 masks during the COVID-19 pandemic”, “Multifaceted changes in life due to mandatory mask wearing”, “Unexpected benefits of wearing a mask”, “Difficulties with wearing masks continue even after the COVID-19 pandemic”. Conclusion: This study confirmed the discomfort and difficulties of prolonged mask wearing among nurses in the context of COVID-19. Our findings suggest that there is a need for organizational and national support for nurses who are required to continue wearing masks after the COVID-19 pandemic.

In this study, we synthesized pH-controlled resorcinol-formaldehyde (RF) gels through the polymerization of two starting materials: resorcinol and formaldehyde. The prepared RF gels were dried using an acetone substitution method, and they were subsequently carbonized under nitrogen atmosphere to obtain carbon xerogels (CX_Y) prepared at different pH (Y). The carbon xerogels were utilized as active materials for coin-type organic supercapacitor electrodes to investigate the influence of pH on the electrochemical properties of the carbon xerogels. The carbon xerogels prepared at lower pH (CX_9.5 and CX_10) exhibited sufficient particle growth, with a three-dimensional network of particles during the RF gel formation, resulting in the development of abundant mesopores. Conversely, the carbon xerogels prepared at higher pH (CX_11 and CX_12) retained densely packed structures of small particles, leading to pore collapse and low specific surface areas. Consequently, CX_9.5 and CX_10 showed high specific surface areas, and provided ample adsorption sites for the formation of electric double layers with electrolyte ions. Moreover, the three-dimensional particle network in CX_9.5 and CX_10 significantly enhanced electrical conductivity. The presence of well-developed mesopores in these materials further facilitated the effective transport of electrolyte ions, contributing to their superior performance as organic supercapacitor electrodes. This study confirmed that pH-controlled carbon xerogels are one of the promising active materials for organic supercapacitor electrodes. Furthermore, we concluded that pH during RF gel formation is a crucial factor determining the electrode performance of the carbon xerogels, highlighting the need for precise pH control to obtain high-performance carbon xerogel electrodes.
