박동호 서울대학교 어학연구소 2004 語學硏究 Vol.40 No.3
The aim of this paper is to examine and analyze diverse aspects in the syntactic realization of predicative noun phrases. In this respect, we first examined the relation between the argument forms of verbs and predicative nouns. Secondly, we analysed four arguments whose forms are respectively 'ui', 'zero', 'e daehan' and 'e uihan' in relation to their functions given by a predicative noun. Thirdly, we analysed the restrictions on the realization of arguments in predicative noun phrases. More specifically, we examined two types of restrictions: restrictions due to the lexical properties of predicative nouns and restrictions due to the argument form of predicative nouns. Fourthly, we examined the omission of arguments occurring in predicative noun phrases and found all the arguments are not necessarily realized in predicative noun phrases: only when an argument proximate to the predicative noun is realized can this predicative noun phrase be grammatical. We also examined a noun phrase previously categorized as predicative which seems to be grammatical even though its proximate argument is not realized and determined it to be a new type of situational noun phrase. In other words, we showed that in order to explain diverse types of argument omission occurring in predicative noun phrases, we have to divide predicative nouns into two types: one used only as a predicative noun and the other used as a predicative and situational noun.

The study on the heater usage for better energy efficiency of domestic convection oven
박동호,서응렬,권명근,박용종 대한기계학회 2018 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.32 No.2
In this study, the heater usage algorithm has been studied for cooking process in a domestic oven. For the analysis, Numerical simulation and experimental study have been performed, focusing on heat distribution and heat loss mechanism. Better fidelity of baking process model was achieved by incorporating enthalpy jump at the phase change and evaporation-condensation mechanism into the thermal properties of cupcake. The result of heat flux calculation over enclosed walls shows that the back surface has the highest heat flux due to high temperature of convection heating during preheating process. During baking process, the heat flux on the top surface of cupcake on a upper tray was found to be about 1.8 times as that on the lower tray due to radioactive heat flux from grill heater. For an energy saving purpose, the more balanced use of heating units, for instance, more use of grill heater than convection heater, was recommended. The thermal conductivity of insulation material was a more important factor than specific heat on the power consumption during preheating.

20 m 점증 왕복달리기 검사를 이용한 여중생의 VO2max 추정식 개발
박동호,송정란,이상현,김창선 한국운동생리학회 2014 운동과학 Vol.23 No.1
Park, Dong-Ho, Song, Jung-Ran, Lee, Sang-Hyun, Kim, Chang-Sun. The Development of Prediction Equation for Estimating VO2max from the 20 m PSRT in Korean Middle-School Girls. Exercise Science, 23(1): 1-11. 2014. The purpose of this study was to develop and validate regression models to estimate maximal oxygen uptake (V O2max) from the 20 m Progressive Shuttle Run Test (20 m PSRT) in Korean middle-school girls aged 13-15 years. The 20 m PSRT and VO2max were assessed in a sample of 194 participants. The sample was randomly split into validation (n=127) and test-retest reliability (n=99, 32 out of 127 participants also performed validity test) groups. 127 participants performed a graded exercise test (GXT, stationary gas analyser) and the 20 m PSRT (portable gas analyser) once to develop a VO2max prediction model and to analyze the validity of the modified 20 m PSRT protocol (starting at 7.5 km/h and increasing by 0.5 km/h every 1 min). 99 participants performed the 20 m PSRT twice for test-retest reliability purpose. Mean measured VO2max (39.2±5.1 ml/kg/min) from the potable gas analyzer was significantly increased from that measured during the GXT from stationary gas analyzer (37.7±5.7 ml/kg/min, p=.001) using the modified 20 m PSRT protocol. But it was a narrow range (1.5 ml/kg/min). The measured VO2max from the potable and stationary gas analyzers correlated at r=.88(p<.001). Test-retest of the 20 m PSRT yielded comparable results (Laps r=.88 & final speed r=.85). New regression equations were developed from present data to predict VO2max for middle-school girls: y=.231XLaps-.311Xweight(in kg)+46.201 (r=.74, SEE=4.29 ml/kg/min). It is concluded that (a) the modified 20 m PSRT protocol is a valid and reliable test and (b) this equation developed in this study provides valid estimates of VO2max of Korean middle-school girl aged 13-15 years.

치수조직염색체에서의 F-body검출에 의한 성별판정에 관한 연구
박동호,김종열 대한안면통증구강내과학회 1984 Journal of Oral Medicine and Pain Vol.9 No.1
The author had tried to identify the sex from single tooth by detecting F-body of Y-chromosome in the nucleus of the dental pulp cells of 70 persons aged from 4 to 61 years under a fluorescent miscroscope. The results were as follows : 1. In the cell nuclei of male and female dental pulp at refrigeratory, the rate of F-body appearancd ranged 42-86%(average 61.06%) in male, while it was 0-6%(average 1.86%) in female, indicationg that male could be distinctly differentiated from female by F-body. 2. With male and female dental pulp puterfide by leaving in at room temperature, the rate of F-body appearance ranged 35-58%(average 48.20%) in male, 1-3%(average1.70%) in female, indicating that it was possible to distinguish male and female by F-body. 3. Even in heat-treated male teeth at $100^{\circ}C$,10 mins, the rate of F-body appearace proved to be 32-56%(averaged 42.50%), also indicating the possibility of identifying male. 4. When detecting of F-body in process of time, the rate of F-body appearance did not show major charges. 5. It was reaffirmed that F-body detection method was a positive determination method of male.
