This study mainly investigated modality adverbs in Modern Chinese. To investigate the characteristics, subclassification, and scope of Chinese modality adverbs, We have studied on ‘concepts of modality and mood’ and ‘subclassification of modality adverbs and mood adverbs’ through previous studies. After that, We presented the perspective of this paper, and reclassified 324 adverbs that presented in previous studies based on ‘modal meanings’. It has come to the following conclusions: First, in previous studies, the concepts of modality and mood are mixed. In the field of Western grammar, some scholars claim that modality is the semantic field, mood is the grammar field. This reflects the characteristics of ‘inflectional language’, but Chinese is ‘isolated language’. So at the time of accepting the concepts of modality, it can be seen that the concepts were mixed. In order to solve this problem, this paper distinguished concepts of modality(情態), mood(语氣₂), tone(口气). Second, in previous studies, each scholar’s classification for modality adverbs and mood adverbs didn’t match. However, researching on the adverbs suggested in previous studies, all of them can be distinguished as dynamic modality, deontic modality, epistemic modality, tone, etc., but tone doesn’t mean modality. So modality adverbs are generally divided into dynamic modality, deontic modality and epistemic modality. Also recently some scholars claim that ‘evaluative modality’ should be classified as a category of modality, but none of the adverbs can be found to indicate the meaning of evaluative modality. Third, after collecting a total of 324 adverbs of modality adverbs and mood adverbs in previous studies, 211 adverbs were excluded for two reasons(not included or presented in a different meaning in XIANDAI HANYU CIDIAN(『现代汉语词典(第7版)』), not indicated the meaning of modality). The remaining 113 adverbs were reclassified into dynamic modality(will), deontic modality, and epistemic modality. Adverbs with multiple modality in the same word were indicated by ‘Bi(必)₁, Bi(必)₂, Bi(必)₃’, and a total of 156 adverbs were classified in this paper. The results of the reclassification are as follows. There are a total of 29 dynamic modality adverbs accounting for about 19% of the total modality adverbs, and a total of 46 deontic modality adverbs accounting for about 29%, and a total of 81 epistemic modality adverbs accounting for about 52%. As the classification results, epistemic modality adverbs are the largest number of modality adverbs.

Purpose : This study aimed to investigate age-related mechanical changes in the erector spinae muscles, specifically in terms of tone, elasticity, and stiffness, in the elderly population compared to the younger population Methods : The mechanical properties, including tone, elasticity, and stiffness, of the erector spinae muscles were measured using myotonometry in 47 male adult subjects, divided into the younger group (23 subjects aged 19 to 28 years) and the elderly group (22 subjects aged 69 to 83 years). The measurements were performed in both the prone and sitting positions. The tone, elasticity, and stiffness of the erector spinae muscles were statistically compared between the two groups using a t-test. Results : The study showed increased stiffness and decreased elasticity in the erector spinae muscles in the elderly group compared to the younger group (p<0.01~0.001). The results were similar in both the prone and sitting positions. Conclusion : There are age-related degenerative changes that affect the mechanical properties of the erector spinae muscles. In addition, myotonometry can be suggested to be a useful examination tool in evaluating these changes provided that further studies are conducted and standard methods of application have been established in the future.

Objectives. The purpose of this study was to compare the oral health behavior of mothers and children from multicultural families and those of mothers and children from ordinary Korean families. Methods. The subjects in this study were 175 mothers of ordinary Korean families and 131 mothers of multicultural families who were selected by convenience sampling from the city of Nonsan. The investigation method was a personal self-administration survey conducted on the mothers of ordinary Korean families, and an interview survey conducted on the mothers of multicultural families by personal visit. The collected data were analysed using a t-test and chi-square test using SPSS software. Results. The multicultural families were far more disadvantaged than the ordinary Korean families when their socioeconomic characteristics were compared. The frequency of cariogenic beverages intake of children from multicultural families was higher than in children from ordinary Korean families. However, the types of families made no differences on how much the mothers curbed their children`s sugar intake to prevent dental caries. Both of the mothers and children from multicultural families brushed their teeth less frequently than the mothers and children from ordinary Korean families, and the multicultural families brushed their teeth less after lunch and before bedtime. Conclusions. The mothers and children from multicultural families had non-desirable oral health behavior when compared to the mothers and children from ordinary Korean families. A supportive environment has to be established to improve the oral health of multicultural families in Korea.

소규모 DC 배전계통에서 사고가 발생할 경우, 기존 AC 배전계통에 비해 사고전류가 매우 가파르게 상승하게 되어, 메인컨버터가 내장된 소자를 보호하기 위하여 탈락하여 수용가에 정전을 유발시킬 가능성이 있다. 따라서, 본 논문에서는 LVDC 배전계통에서 사고에 의한 메인컨버터의 탈락을 방지하기 위하여, 사고전류를 제한시킬 수 있는 LVDC선로용 4kW급 사고구간 분리용 보호장치를 구현한다. 이 장치는 반도체 스위치와 게이트 드라이브, 전류제한 저항, 전압 및 전류센서로 구성된 H/W부와 TM320F28335를 기반으로 한 S/W부 등으로 구성되며, 동작 메커니즘은 초기 동작모드, 보조 동작모드, 주 동작모드, 회복 동작모드의 4가지 모드로 운용된다. 여기서, H/W부는 IGBT(insulated gate bipolar transistor)와 전류제한 저항, 센서 등을 이용하여 주 통전부와 전류 제한부를 구성하고, S/W부는 CCS(code compose studio) 프로그램과 DSP(digital signal processor), A/D(analog/digital) 변환기 등을 이용하여 스위치의 제어를 수행한다. 상기에서 제시한 사고구간 분리용 보호장치의 동작 특성을 분석한 결과, 350V DC 계통에서 사고가 발생한 경우 사고구간 분리용 보호장치가 55.2~72.5[μs] 이내로 사고전류를 신속하게 제한하여 사고구간을 분리할 수 있는 시간을 확보할 수 있고, 이를 통하여 메인컨버터의 탈락을 방지하여 LVDC 배전계통의 정전을 최소화시킬 수 있음을 알 수 있다. When a fault occurs in an LVDC distribution system, the fault region may be extended due to shutdown of the main converter to protect internal devices. Therefore, this paper presents a 4-kW scaled-protection device for isolating a fault section to limit the fault current and prevent this shutdown. The proposed device is composed of a hardware system and a software system and has four operation modes: initial mode, auxiliary mode, main mode, and restoration mode. The hardware system is composed of a main path, current limit path using an IGBT, current limit resistor, sensors, etc. The software system performs monitoring and controlling of the switches using a code composition studio (CCS) program, DSP, A/D converter, etc. From the test results based on 4-kW 350-V DC distribution, it was confirmed that the proposed protection device for isolating a fault section can limit the fault current within 55.2-72.5 [μs] of the reference value in the LVDC distribution system and ensures isolation time for the fault section. Therefore, it is clear that the proposed device could be a useful tool to isolate a fault section by preventing shutdown of the main converter and minimizing a fault region in an LVDC distribution system.
