지구 자기권에 존재하는 플라즈마 입자의 다중관측을 목적으로 개발된 초소형 탑재체 STEIN (SupraThermal Electron, Ion, Neutral) 은 경희대학교와 UC Berkeley가 공동으로 개발 중인 3대의 초소형 과학위성 TRIO-CINEMA (TRiplet Ionosphere Observatory - Cubesat for Ion, Neutral, Electron and MAgnetic fields) 에 탑재될 입자 검출기이다. 32개의 픽셀로 이루어진 STEIN 검출기는 2~300 keV의 전자, 4~300 keV의 이온과 중성입자(Energetic Neutral Atom: ENA) 를 분리 계측할 목적으로 설계되었으며, 하전입자가 정전장 편향기를 통과하여 서로 다른 검출기 픽셀에 도달함으로써 전자와 이온, 중성입자를 분리하여 계측할 수 있도록 하였다. 한편, STEIN 구조물에서 발생한 2차 입자의 검출을 방지하기 위해 정전 편향기 사이에 차단날(blade)을 설계하였다. 본 연구에서는 STEIN 모의실험 예비 결과로써 전기장에 크기 및 차단날에 의한 하전입자의 궤적과 이에 따른 분리 계측 성능을 알아보고자 Geant4 (GEometry ANd Tracking)를 사용하여 검출기 픽셀에 입사하는 전자의 초기 위치를 분석하였다. 전자의 입사 위치는 검출기로부터 5 cm 전방에서 6 mm * 20 mm 범위 내에서 무작위로 생성하여 검출기의 방향으로 수직 입사하였다. 분석 결과 전자들은 전기장의 방향에 따라 편향되는 결과를 보였으며, 저에너지 전자는 강한 전기장의 영향으로 차단날에 의해 차폐되어 검출되지 않았다. 따라서 전기장의 크기와 차단날에 따른 입자 분리 검출이 가능함을 본 모의실험을 통해 확인하였으며, STEIN 운용 시 입자 분리 검출 및 결과 분석 기반으로 본 연구 결과를 사용될 수 있을 것으로 기대된다.

The effects of task characteristics on the relative efficiency of visual display dimension were studied using a simulated tele-robotic task. Through a conventional method of task analysis. the tele-robotic task was divided into two categories: the task element requiring focused attention (FA task) and the task element requiring global attention (CA task). Time-ta-completion data were collected for a total of 120 trials involving 10 participants. For the CA task. there was no significant difference between the multiple two-dimensional (20) display and the three-dimensional (3D) monocular display. For the FA task. however. the multiple 20 display was superior to the 3D monocular display. The results suggest that the characteristics of a given task have a considerable effect on the choice of display dimensionality and the multiple 3D display is better for human operators to effectively judge depth if the task requires frequent use of focused attention.

언어유형론적인 관점에서 인식적 가능성을 표현하는 문법형태 고찰 - 중국지역 중국·티베트어의 인식양태의 가능성(possibility)을 중심으로

박성하(Park, Seong-ha) 한국중어중문학회 2020 中語中文學 Vol.- No.79

This thesis is a study analyzing the grammatical components showing the possibility of epistemic modality targeting 45 languages belongs to Sino-Tibetan languages of China from linguistic typological point of view. Firstly, I examined the name and classification system expressing epistemic possibility in Sino-Tibetan languages of China, then found that ′Nung language′, ′Gyalrong language′, ′Pumi language′ and ′Qiang language′ are classified as the auxiliary verbs changing for ′person/number/tense′ and another auxiliary verbs not changing. Especially, in case of ′Gyalrong language′, it is classified as ′independent auxiliary verb′ or ′dependent auxiliary verb′. Secondly, I examined the word order and realization method of grammatical components expressing epistemic possibility with the verb, and found that the word order of auxiliary verb and verb is quite close relationship with language group. In case of realization method, most of language expresses the modality meaning with independent grammar components, however, affix or phonetic inflection in partial languages. At last, I examined polysemous aspects of possibility modality sign, and found that the auxiliary verbs examined in this thesis also has various grammatical meaning such as ′capability′, ′permission/authorization′, ′future tense′ and so on besides the modality meaning of possibility as shown in most of modality auxiliary verbs. Also, I examined the relationship with mandarin, and found that there are not less languages using auxiliary verbs borrowed from mandarin. Especially, the auxiliary verbs expressing the modality meaning of ′possibility′ were heavily borrowed.

양태조동사 `能`의 하위분류 및 주어와의 공기특성 분석

박성하(Park, Seong ha) 한국중어중문학회 2015 中語中文學 Vol.61 No.-

This paper is a study which considered the properties of “neng” through the analysis of the co-occurrence properties with subjects of “neng” as a modality auxiliary verb of modern Chinese. Above all, based on the modality functions of “neng”, the subdivision was processed. In dynamic modality, there are largely “ability”, “conditions”, and “use”. “Ability” is classified into “strong ability” and “weak ability” according to the degree. “Strong ability” is assorted into “strong ability: skill” and “strong ability: talent”, and “weak ability” is assorted into “weak ability: capability” and “weak ability: potential” in detail. “Conditions” are classified into “conditions: subjective” and “conditions: objective” according to whether the decision to be realized or not is dependent on what direction. Deontic modality is sorted into “permission” and “authorization”. “Authorization” is sorted into “authorization: acceptance” and “authorization: norms” according to subjects and objects to authorize in detail again. Epistemic modality is classified into “speculation” and “possibility”. Next, in the paper, based on the sub-classification of “neng”, whether there is co-occurrence with subjects or not were examined. “Ability” of dynamic modality is possible for co-occurrence with all animate subjects in case of “subjective things”. It is impossible for co-occurrence with inanimate subjects. In case of “objective conditions”, they showed complimentary distribution with “subjective conditions”. In case of deontic modality, “permission” and “authorization: acceptance” showed complimentary distribution. “Authorization: norms” is possible for co-occurrence with all subjects. In case of deontic modality, it was mostly possible for co-occurrence with all subjects. But, in case of “supposition”, it is impossible for co-occurrence with the first-person subjects. In conclusion, in “neng”, in case of dynamic modality and deontic modality, aspects of co-occurrence are represented differently according to subjects. Also, it can be known that in case of epistemic modality, it is not under the restriction of co-occurrence with subjects.

중국 내 소수민족 언어의 방향 관련 동사성 표현 고찰

박성하 ( Park Seong-ha ) 중국학연구회 2021 중국학연구 Vol.- No.95

본 논문은 중국지역 소수민족 언어의 방향을 나타내는 동사성 성분을 연구하였다. 본고에서 다루는 중국지역 내 언어로는 ‘티베트 어군(Tibetan Languages)’ 4개, ‘징포 어군(Jingpo Languages)’ 7개, ‘몐 어군(Burmese Languages)’ 4개, ‘창 어군(Qiang Languages)’ 6개로 총 21개이다. 본 논문에서는 이 언어들을 대상으로 방향을 나타내는 동사성 표현들을 유형별로 분류하고 분석을 진행하였다. 첫째, 본 논문에서는 방향동사를 가진 언어들을 살펴보았다. 연구 대상 언어 21개 중에서 ‘페라어(Pela)’와 ‘셴다오어(Xiandao)’에서 방향동사가 있음이 확인되었는데, 이들 언어들은 모두 ‘오다’의 의미와 ‘가다’의 의미를 하나의 동사로 표현하고 동작의 방향 및 높낮이에 따라 각각 다른 동사를 선택해서 사용한다. 둘째, 본 논문에서는 방위첨사를 가진 언어들을 살펴보았다. ‘이두어(Yidu)’, ‘쑤룽어(Sulung)’ 그리고 ‘셴다오어’가 방위첨사를 가지고 있음이 확인되었다. 이들 언어들은 모두 ‘높낮이’를 나타내는 방위첨사를 가지고 있으며, 또한 ‘화자를 기준’으로 하여 방향을 나타내는 체계를 가지고 있다. 셋째, 본 논문에서는 방향을 나타내는 동사접사를 가진 언어들을 살펴보았다. 먼저, 방향접두사를 가진 언어는 총 7개이고, ‘바이마어(Baima)’가 가장 많은 수의 접두사를 가지고 있다. 다음으로 방향접미사를 가진 언어는 2개인데, ‘터룽어(Drung)’와 ‘눙어(Nung)’가 이에 해당한다. 특히 ‘눙어’의 방향접미사는 상당히 발달되어 있고 체계적이다. 마지막으로 분석 내용을 토대로 방향을 나타내는 표현들의 상호 관련성에 대해 살펴보았다. 한 언어 내에서 방향을 나타내는 표현이 여러 개일 경우, 상호보완적인 관계이며 또한 문법화의 과정을 거쳐 만들어진 표현인 경우가 많다는 것이 확인되었다. This paper investigated verbal components indicating directions in the languages of minority ethnic groups in China. The total number of minority languages in China covered in this paper is twenty-one including four ‘Tibetan languages,’ seven ‘Jingpo languages,’ four ‘Burmese languages’ and six ‘Qiang languages.’ In this paper, verbal expressions indicating directions in these languages were classified by type and then analyzed. First, we examined languages with directional verbs. Among the twenty-one languages studied, it was confirmed that there are directional verbs in ‘Pela’ and ‘Xiandao,’ both of which have a single verb for the meanings of ‘to come’ and ‘to go,’ and they use different verbs depending on the direction and height of the movement. Second, we examined languages with directional particles. It was confirmed that ‘Yidu,’ ‘Sulung’ and ‘Xiandao’ have directional particles. All of these languages have directional particles indicating height, and also have a system where directions are indicated on a speaker basis. Third, we examined languages with verb affixes indicating directions. First, a total of seven languages has directional prefixes, among which ‘Baima’ has the largest number of directional prefixes. Next, there are two languages with directional suffixes: ‘Drung’ and ‘Nung.’ In particular, the directional suffixes of ‘Nung’ are quite developed and systematic. Finally, based on the above analyses, we examined the interrelationship of directional expressions. It was confirmed that when there are multiple directional expressions in a language, they are complementary to each other and are often made through the process of grammaticalization.

부사 및 동사(구)와의 공기특성으로 살펴 본 양태조동사 ‘능(能)`의 문법화 경로

This dissertation studies the characteristics of co-occurrence of the modern Chinese modality auxiliary verb ‘能(neng)` with adverb and verb (phrase). Firstly, classified the modality auxiliary verb ‘能(neng)` into dynamic modality, deontic modality and epistemic modality from extracted sentences containing modality auxiliary verb ‘能(neng)` and then examined the types of adverbs that occurs with modality auxiliary verb ‘能(neng)` simultaneously. 能 (neng)` of dynamic modality(capability) could co-occur with every forms of adverb except ‘probability`, but the ‘能(neng)` of epistemic modality could co-occur with ‘probability` adverb. Deontic modality ‘能(neng)` has a tendency of not going with adverbs. Secondly, examined the verb phrases that co-occurs with ‘能(neng)` in accordance with their types of pattern. ‘能(neng)` of dynamic modality is mostly used with the verbs that has an independent one syllable and tend to bring complement. ‘能(neng)` of deontic modality appears mainly with bare verb in many cases and mainly accompanied in interrogative sentence or negative statement. In the case of epistemic modality ‘能(neng)`, it mostly comes up with two syllable verbs and takes high percentage of appearance with ‘有(you)` or ‘是(shi)`. Lastly, examined that the modality auxiliary verb ‘能(neng)`s grammaticalization and its process are not a chinese individual but an universal phenomenon on the basis of the analysis of syntax through this paper.
