Purpose: Diabetes Mellitus (DM) is a leading cause of death with a prevalence rate of 12.4% in South Korea. Self-management is crucial for patients with DM, because many studies have reported that self-management intervention based on the Health Belief Model (HBM) is effective. The purpose of this study was to investigate the current state of HBM based intervention studies and the components and effects of the theories used in the study for diabetes patients. Methods: A systematic review was conducted using the Pubmed, Cochrane Library and Embase databases from January 2009 to May 2019. We reviewed characteristics of intervention based on the HBM in randomized controlled clinical trials (RCTs), quasi-experimental study intervention. Results: Eight studies published in English between 2009 and 2019 were included in this review. The key components of the health behavior promotion program applied to the DM patients were perceived susceptibility, perceived severity, perceived benefits, perceived barriers and self-efficacy. The intervention based on these components has reported to significantly increase the health behavior change, likelihood of taking health action and improve physiological indicators (HbA1c, and fasting blood sugar etc.). Conclusion: This study highlighted the importance of intervention programs based on the HBM for DM patients.

Timely fault identification is important for safe and reliable operation of the electric valve system. Many research works have utilized different data-driven approach for fault diagnosis in complex systems. However, they do not consider specific characteristics of critical control components such as electric valves. This work presents an integrated shallow-deep fault diagnostic model, developed based on signals extracted from DN50 electric valve. First, the local optimal issue of particle swarm optimization algorithm is solved by optimizing the weight search capability, the particle speed, and position update strategy. Then, to develop a shallow diagnostic model, the modified particle swarm algorithm is combined with support vector machine to form a hybrid improved particle swarm-support vector machine (IPs-SVM). To decouple the influence of the background noise, the wavelet packet transform method is used to reconstruct the vibration signal. Thereafter, the IPs-SVM is used to classify phase imbalance and damaged valve faults, and the performance was evaluated against other models developed using the conventional SVM and particle swarm optimized SVM. Secondly, three different deep belief network (DBN) models are developed, using different acoustic signal structures: raw signal, wavelet transformed signal and time-series (sequential) signal. The models are developed to estimate internal leakage sizes in the electric valve. The predictive performance of the DBN and the evaluation results of the proposed IPs-SVM are also presented in this paper.

본 연구는 존 그린리프 위티어의 반노예제 시를 분석하려는 시도이다. 독실한 퀘이커 교도인 위티어는 19세기에 만연한 노예제를 비판했다. 그의 활동은 종교적 신념에 기반한 것이었다. 노예폐지운동에 언론인 등으로 참여했던 위티어는 1830년대부터 1860년대 중반까지 집중적으로 반노예제시를 썼다. 「버지니아 노예 어머니의 이별」은 남부로 팔려간 딸에게 느끼는 노예 어머니의 비통한 심정을 묘사하며 독자의 공감을 유도한다. 「매사추세츠에서 버지니아로」에서 화자는 버지니아의 도덕적 타락에 비통해 하면서 노예를 노예주로 되돌려보내는 것을 거부한다. 「마침내 오르다」는 떠오르는 달을 정치적, 사회적 상징으로 사용하면서, 도주 노예법의 통과를 찬양한다. 남북 전쟁 이후에 작시된 「평화의 가을」은 노예 해방이 선포된 후 평화로운 상황을 묘사한다. 위티어의 노력은 노예해방 운동과 문학에 기여한 바가 크다.

본 연구는 COVID-19의 세계 대유행 상황에서 대학생들의 신종감염병 예방행동의도영향 요인을 살펴본 연구로, 주요 연구 결과는 다음과 같다. 첫째, 대학생들의 일반적 특성에 따른 조사 결과 2학년 학생들에서 예방행동의도가 4.11점으로 유의한 차이를 보였으며(p<.05), 건강행태 결과에서는 섭식상태에서 예방행동의도에 영향을 미친 것으로 나타났다(p<.05). 둘째, '심각성' 요인은 예방행동의도에 긍정적인 영향을 주는 것으로 나타났으며(β.164) 셋째, '민감성' 요인은 예방행동의도에 영향을 미치지 않는 것으로 조사되었다. HBM연구에서 민감성은 중요요인으로 예방행동으로 인해 발생할 수 있는 이익이 높을수록 반대로 예방행동으로 인한 손실이 낮을수록 예방행동의도가 높게 나타나 예방행동의도 형성에 도움이 될 것으로 해석한다. 그러나 본 연구에서는 민감성이 예방행동의도에 영향을 미치지 않았다는 결과는 감염병에 대한 안전불감증이 존재하는 것으로 여겨지며 '부정적 사건이 일어나지 않을 것' 이라는 인지적 경향 보여진다. 넷째, '자기효능감'은 주요 변수에서 가장 큰 설명력을 보였다(β.640).

The metal intercalation to an organic semiconductor is of importance since the charge transfer between a metal and an organic semiconductor can induce the highly enhanced conductivity for achieving efficient organic electronic devices. In this regard, the changes of the electronic structure of copper phthalocyanine (CuPc) caused by the intercalation of potassium are studied by ultraviolet photoemission spectroscopy (UPS) and density functional theory (DFT) calculations. Potassium intercalation leads to the appearance of an intercalation-induced peak between the highest molecular occupied orbital (HOMO) and the lowest molecular unoccupied orbital (LUMO) in the valence-band spectra obtained using UPS. The DFT calculations show that the new gap state is attributed to filling the LUMO+1, unlike a common belief of filling the LUMO. However, the LUMO+1 is not conductive because the ${\pi}$-conjugated macrocyclic isoindole rings on the molecule do not make a contribution to the LUMO+1. This is the origin of a metal-insulator transition through heavily potassium doped CuPc.

This study examined young children's beliefs about trait stability based on trait type and valence. Participants included 120 children (40 three-year-olds, 40 four-year-olds, and 40 five-year olds) recruited from 3 day-care-centers and 1 kindergarten in Seoul and Kyung-Ki province. Results revealed that young children's understanding of traits differed based on trait type and valence. Children demonstrated a strong belief that social-intention traits are more stable and harder to change when compared to internal-state traits. Young children's beliefs on trait stability were also strongly influenced by trait valence. They believed that negative traits are more likely to change for the better while positive traits have greater stability and are less likely to change over time.

This paper discusses several basic issues of the 'focus' phenomenon. One of them is the issue of the nature of focus, i.e., what constituent of the sentences gets focused. Another is the issue of to what aspect of meaning the focus contributes. The other is the issue of the functions of focus-sensitive operators. As for the first issue, it is observed that the basic function of focus is to mark all and only the new information of the sentence. But for the cases in which this principle is not observed, it is proposed that the focus in these cases in general plays a secondary function of triggering an additional emphatic scalar meaning. And yet, in these cases, the state of the matter is different between free focus and bound focus. It is also shown that contrary to the general belief that free focus contributes to the meaning semantically. Concerning focus-sensitive operators, we classify them into two groups, i.e., quantificational and scalar operators, and try to formalize their meaning in the framework of Pulman's(1997) 'higher order unification theory'.

Telecare, one of the e-healthcare services with lCT, is a promising technology which aims to monitor the state of patients and then provide the medical services appropriately in remote sites. Virtual telecare team based on the concept of virtual collaborative teams which consist of a patient, a doctor, and a telecare team, operates on a temporary basis in need. Reputation, which means the degree of a patient's belief to a doctor in consideration, is the most important factor to make the virtual telecare team trustable. In this paper, we propose the fuzzy reputation model of a virtual telecare team, which is a reputation-based trust model based on fuzzy set theory. An illustrative example is also given in order to show the applicability of the model to the concept of a virtual telecare team.

The purpose of this paper is to make a sentence systemic within the category of structural grammar for the modality in which a speaker expresses his attitude. It is the priority of a language to communicate meaning. By eliminating the theoretical description of traditional grammar, this paper also aims to illustrate the concepts of nine modal verbs through a systemic network. The concept of modality includes both the epistemic and the deontic characteristics of modality. Epistemic modality is associated with either knowledge or belief on the part of a speaker who gives his own judgments about the state of affairs, events, or actions. However, deontic modality is related to either the possibility or the necessity of acts that a speaker performs to give permission or fulfill an obligation. In conclusion, all the subsystems are described within the framework of the systemic network, with the intention of including all the potential options of the semantic functions available in a situation.
