태권도장 지도자들의 직무스트레스와 조직몰입의 관계에서 회복탄력성의 조절효과
정명규,박신재 한국체육과학회 2024 한국체육과학회지 Vol.33 No.1
This study aims to provide strategic insights for enhancing human resource management in Taekwondo schools, focusing on the retention of high-quality instructors. It examines the moderating role of resilience in the relationship between job stress and organizational commitment among Taekwondo instructors, utilizing the PROCESS macro model 1 (Hayes, 2018) for its robustness in analyzing interaction effects. The results indicate that the impact of job stress on organizational commitment varies with the instructors' resilience level, suggesting that higher resilience can weaken the adverse effects of job stress. Based on the findings of this study, it is suggested that headmasters, who are central to the leadership dynamics within Taekwondo schools, should employ effective leadership styles tailored to the individual characteristics of their instructors in order to enhance their resilience.

Sodium molybdate 의 납중독성 말초 신경계독성 예방기전
정명규,강순국,김명녀 한국환경과학회 2000 한국환경과학회지 Vol.9 No.3
The preventive effects of sodium molybdate on the acute toxicity of lead were studied by investigating tissue accumulation of lead, changes of nerve conduction velocity and concentrations of metabolites related to function of sciatic nerve in rats treated with lead, sodium molybdate and both, respectively. In lead-intoxicated rat, the conduction velocity, myo-inositol concentration and Na^+/K^+ ATPase activity of sciatic nerve were decreased by about 33 %, 48 % and 58 %, respectively. However, sodium molybdate treatment significantly normalized the conduction velocity, Na^+/K^+ ATPase activity and myo-inositol concentration of sciatic nerve in lead-intoxicated rat. Also, sodium molybdate treatment decreased the contents of lead in blood and sciatic nerve through promotion of urinary excretion of lead. But sodium molybdate treatment did not affect the glucose concentration in sciatic nerve. These results suggest that sodium molybdate prevented peripheral neuropathy not only by reducing lead contents in sciatic nerve and blood, but also by enhancing Na^+/K^+ ATPase activity in sciatic nerve.

Sprague-Dawley 랫드의 대퇴 신경증 axonal transport에 미치는 납의 영향
정명규 성화대학교 1993 成和論叢 Vol.- No.3
This study was carried out to elucidate the toxic mechanism of lead in peripheral nerve. An animal model of lead neuropathy was induced by feeding diet containing lead to Sprague-Dawley rat for two weeks. Four weeks aged Sprague-Dawley rats were divided into four groups : normal control, 10ppm-lead treated group, 100ppm-lead treated group, reference drug-treated group. AU rats were sacrificed at the end of six weeks for assessing the development of lead neuropathy. These results obtained were summarized as follows: 1. Polyol pathway activity which was concerned with the peripheral neuropathy was not affected by the 9lead treatment. 2. Reduction in myo-inositol content of peripheral nerve which was obtained from an experimental rat resulted from the interference of transport system. 3. Lead inhibited the activity of sodium potasium ATPase that was responsible for myo-inositol transport in peripheral nerve. 4. Oarl administration of myo-inositol improved the nerve axonal transport in lead intoxicated rat. These results suggest that mild lead neuropathy might be diagnosed by checking nerve myo-inositol content and oarl administration of myo-inositol might prevent the development of severe lead neuropathy with special reference to defective axonal transport.
