Objective: To investigate the association between functional tumor burden of peritoneal carcinomatosis (PC) derived from diffusion-weighted imaging (DWI) and overall survival in patients with advanced ovarian carcinoma (OC). Materials and Methods: This prospective study was approved by the local research ethics committee, and informed consent was obtained. Fifty patients (mean age ± standard deviation, 57 ± 12 years) with stage III–IV OC scheduled for primary or interval debulking surgery (IDS) were recruited between June 2016 and December 2021. DWI (b values: 0, 400, and 800 s/mm2) was acquired with a 16-channel phased-array torso coil. The functional PC burden on DWI was derived based on K-means clustering to discard fat, air, and normal tissue. A score similar to the surgical peritoneal cancer index was assigned to each abdominopelvic region, with additional scores assigned to the involvement of critical sites, denoted as the functional peritoneal cancer index (fPCI). The apparent diffusion coefficient (ADC) of the largest lesion was calculated. Patients were dichotomized by immediate surgical outcome into high- and low-risk groups (with and without residual disease, respectively) with subsequent survival analysis using the Kaplan-Meier curve and log-rank test. Multivariable Cox proportional hazards regression was used to evaluate the association between DWI-derived results and overall survival. Results: Fifteen (30.0%) patients underwent primary debulking surgery, and 35 (70.0%) patients received neoadjuvant chemotherapy followed by IDS. Complete tumor debulking was achieved in 32 patients. Patients with residual disease after debulking surgery had reduced overall survival (p = 0.043). The fPCI/ADC was negatively associated with overall survival when accounted for clinicopathological information with a hazard ratio of 1.254 for high fPCI/ADC (95% confidence interval, 1.007–1.560; p = 0.043). Conclusion: A high DWI-derived functional tumor burden was associated with decreased overall survival in patients with advanced OC.

豫剧豫西调源流探析

伊河 ( Yi¸ He ) 한국중국학회 2021 중국학보 Vol.97 No.-

豫西调本源问题一直是学术界争论的焦点, 争论的关键问题是豫西调来源于祥符调还是山陕梆子。大多数学者认为祥符调是豫剧的母调, 豫西调来脱胎于祥符调, 然而判断一种声腔源流最重要的方法是从板式和节奏上着手, 研究是否同其它声腔有相似之处。豫西梆子在孕育与形成的过程中, 其节奏、板式受到了梆子腔的影响, 但音乐旋律却随流传地域语言、语音及当地的民间音乐变化而发生了改变。当梆子腔流传到豫西一带, 便迅速与当地的民间音乐及语言、语音相结合而形成“豫西梆子”。同理流传到豫东一带就会形成祥符调、豫东调。然而, 时至今日, 豫西山区依然保留有豫西调的最原始状态的唱腔(靠山簧班社)。通过田野调查研究发现, 靠山簧的唱腔中存在两大腔调与豫剧的两腔调关系甚为密切。在没有典籍记载的情况下通过民间俗谚、文献法、曲调考证法对豫西调源流的研究来探讨与河南梆子、祥符调、山陕梆子及其它梆子腔之间的关系, 最后得出结论豫西调就是河南梆子的前身, 同时为五声宫调式。 The origin of the Western Henan Tune has always been the focus of academic debate. The key issue of the debate is whether the Western Henan Tune comes from Xiangfu Tune or Shanshan Bangzi. Most scholars believe that Xiangfu tune is the main tone of Henan opera. The western Henan tune is derived from Xiangfu tune. However, the most important way to determine the origin of a tune is to see whether it is similar to other tunes in terms of style and rhythm. In the process of gestation and formation of the clapper in western Henan, the rhythm and style of the clapper were influenced by the clapper's accent. Then the melody changes with the spread of regional language, pronunciation and local folk music. When the Bangzi accent spreads to the west of Henan, it will be combined with the local folk music, language and pronunciation to form the “Western Henan Bangzi”. When it spreads to the east of Henan, it will form the Xiangfu tune and the Eastern Henan tune. However, to this day, the mountainous area in western Henan still retains the most primitive singing voice of the Western Henan Tuning (Kaosh Theatrical troupe). In the absence of records in the classics, through the study of folk proverbs, literature methods, and tune textual research on the origins of Western Henan Tiao, the relationship with Henan Bangzi, Xiangfu Tune, Shanshan Bangzi and other Bangzi accents is discussed, and the final conclusion is Conclusion The Bangzi in the west of Henan is the predecessor of the Bangzi in Henan, and it is also the five-tone palace mode.

Predicting digital informal learning: an empirical study among Chinese University students

Tao He,Chang Zhu,Frederik Questier 서울대학교 교육연구소 2018 Asia Pacific Education Review Vol.19 No.1

Although the adoption of digital technology has gained considerable attention in higher education, currently research mainly focuses on implementation in formal learning contexts. Investigating what factors influence students’ digital informal learning is still unclear and limited. To understand better university students’ digital informal learning (DIL), this study proposed a model based on decomposed theory of planned behavior to investigate students’ behavioral intention to DIL. Different aspects of DIL behavior were further explored, through examining behaviors of cognitive learning, metacognitive learning, and social and motivation learning. This study also integrated digital competence as a new construct into the model, along with other variables to test the proposed model. A sample of 335 students selected from three universities in China took part in this study. The partial least square structural equation modeling was applied to analyze the data. The results provide support and better understanding for the importance of motivation factors such as digital competence and compatibility to explain students’ DIL.

Focalization Analysis of Locative Inversion in English and Korean

Chung, He Ja 대한언어학회 1999 언어학 Vol.7 No.1

Chung, He-ja. 1999. Focalization Analysis of Locative Inversion in English and Korean. Linguists s, 7-1, 71-84. Inversion of major constituents can occur quite freely in English as well as in Korean within movement or base-generation framework. Contrary to Stowell (1981), Kim (1977), it is proposed here inversion is to be derived from focus movement for English and Korean. Following Miyagawa (1977), local IP-adjunction creates a site which can license the focus feature, guaranteeing movement of any major constituents. This is the case of locative inversion which is a result of IP-adjunction. (Iksan College)

Characterization of the effect of He⁺ irradiation on nanoporous-isotropic graphite for molten salt reactors

Zhang, Heyao,He, Zhao,Song, Jinliang,Liu, Zhanjun,Tang, Zhongfeng,Liu, Min,Wang, Yong,Liu, Xiangdong Korean Nuclear Society 2020 Nuclear Engineering and Technology Vol.52 No.6

Irradiation-induced damage of binderless nanoporous-isotropic graphite (NPIG) prepared by isostatic pressing of mesophase carbon microspheres for molten salt reactor was investigated by 3.0 MeV He⁺ irradiation at room temperature and high temperature of 600 ℃, and IG-110 was used as the comparation. SEM, TEM, X-ray diffraction and Raman spectrum are used to characterize the irradiation effect and the influence of temperature on graphite radiation damage. After irradiation at room temperature, the surface morphology is rougher, the increase of defect clusters makes atom flour bend, the layer spacing increases, and the catalytic graphitization phenomenon of NPIG is observed. However, the density of defects in high temperature environment decreases and other changes are not obvious. Mechanical properties also change due to changes in defects. In addition, SEM and Raman spectra of the cross section show that cracks appear in the depth range of the maximum irradiation dose, and the defect density increases with the increase of irradiation dose.

Abstract A Survey of Structural Analyses on English Intonation Lee, Sang-Do·Kim, He-Kyung Intonation is narrowly defined as the melody of speech in the papeer. One of the approaches on English intonation is structural analysis, which can be applied to teaching English as a foreign language. The structural approach aims at postulating intonation unit and intonation inventory to describe the form and meaning of intonation. The teaching of English intonation is often considered as a difficult task. Thompson(1995) argues that the average teacher is uncomfortable with intonation, treating it as a difficult subject and difficult to fomulate rules. As such it tends to receive little explicit focus in the classroom. In order to be helpful to teaching, intonation model, which is teachable, learnable, and simple, should be devised unlike the existing ones proposed by various specialists. To devise the model, structural analyses should be examined since they focus on the linguistic functions and meaning of intonation in English to choose the most appropriate analysis that capture general behaviors of intontion. This paper, thus, examines structural analyses on English Intonation. Structural analyses are divided into level and configuration approach. Level approach by Pike(1945). Trager/Smith(1957) and Prator/Robinett(1985) fails to capture general linguistic behaviors of intonation compared to other linguistic elements by proposing that the pitch contour are sequences of pitch phonemes. Configuration approach includes tune analysis, tone analysis, and tone-tune analysis. Tune approach by Armstrong/Ward(1931) prescribes two basic tones showing that pitch movement only plays a contrastive role. The approach unlike the level one shows the important role of pitch movement but also fails to show that the pitch pattern of pre-tonic which adds or modifies the whole meaning of the contour. Tone approach by Kingdon(1958) recognizes the role of pitch height and postulates kinetic and static tones. But it also prescribes pitch pattern of English intonation rather than describing. Tone-tune approach by O'Connor/Arnold(1972) and Hallway(1985) shows that the pitch contour has the internal structure. O'Connor/Arnold argues that the pitch contour consists of three optional elements and one obligatory element. Halliday(1985) argues that the pitch contour consists of one optional elements and one obligatory elements. By showing that the pitch pattern or so called INTONATION UNIT has the internal structure, the tone-tune approach captures generality of English intonation . Thus it can be concluded that the tone-tune approach can be employed to the field of Teaching English as a Foreign Langauge.

초기 사회화 과정을 중심으로 본 남·여 역할 분화에 관한 한 비판적 고찰

This paper is intended as an attempt to describe and explain the process by which a child becomes a member of his/her society and develops the expected pattern of behavior associated with a particular sex. Current important theoretical and empirical researches in the field of early sex-role socialization are cited and discussed. The authors refute the assumption that the root of sex-role differentiation goes down to the physical and physiological heritage of human organism, while they present sociological, psychological, and anthropological data to support the thesis that what is naturally masculine or feminine is not only inextricably linked to cultural convention but also largely determined by the socio-cultural demands inherent in a particular social structure. The first section reviews some rather diverse studies. Taking a close look at the sex differences in ability and achievement motivation, it points out that differences between the sexes in ability and in amount of motivation are not evident at birth and early age but emerge slowly as the child grows out of the relationship he/she makes with the various environments. Females' disabilities and underachievement in many areas do not have any innate, biological basis but are due to both social and cultural forces. The second section presents in outline form the most salient factors shaping females' roles within the social normative framework of Korean society. It is intended as an illustration of how sex-role differentiation is institutionalized. The traditional value patterns of Korean society are seen as preventing women from actively developing their potentials by confining feminine role within family life. Despite a seeming achievement of modern transformation the fundamental patterns of traditional family system so far remain a formidable obstacle to all attempts to innovate the structure of sex-role differentiation. The final section discusses the current situation of females in society and argues that the existing structure of sex-role differentiation net merely interrupts development and underutilizes the potential of half of population but dehumanizes females. Role-innovations going beyond the sex-role structure is urged as a humane gesture.
