The mean score of working conditions for labor workers were significantly higher than that of clerical workers. Among 4 factors of working conditions, the higher score were shown in the working and environment factors with 1.22 and 1.18, respectively. 2. Symptom prevalence rate of CTD for workers was $81.0\%\;{;}\;82.9\%$ for labor workers and $77.0\%$ for clerical workers. As for symptom of CTD in body part, higher rate were shown in lower back with $50.2\%$, shoulder and neck with $38.4\%\;and\;36.4\%$ respectively. 3. The score of symptom severity of CTD were 3.45. Significant difference was shown in symptom severity of forearm and wrist/hand part between labor and clerical workers. As for symptom severity of CTD in body part the higher score were shown in shoulder, ankle/foot, forearm. lower leg and elbow. and the highest score for labor workers were shoulder and ankle/foot and for clerical workers was lower back. 4.

Since Alarm Monitoring Service was introduced in Korea in 1981, the market has been increasing and is expected to increase continually. Some factors such as the increase of social security need and the change of safety consciousness, increase of persons who live alone could be affected positively on Alarm Monitoring Service industry. As Alarm Monitoring Service come into wide use, the understanding of electronic security service is spread and consumer's demand is difficult, so consideration about new developmental plan is need to respond to the change actively. Electronic security system is consist of various kinds of element, so every element could do their role equally. Alarm Monitoring Service should satisfy consumer's various needs because it is not necessary commodity, also electronic security device could be easily operated and it's appearance has to have a good design. To solve the false alarm problem, detection sensor's improvement should be considered preferentially and development of new type of sensor that operate dissimilarly to replace former sensor is needed. On the other hand, to settle the matter that occurred by response time, security company could explain the limit on Alarm Monitoring System to consumer honestly and ask for an understanding. If consumer could be joined into security activity by security agent's explanation, better security service would be provided with mutual confidence. To save response time the consideration on the introduction of GIS(Global Information System) is needed rather than GPS(Global Positioning System). Although training program for security agents is important, several benefits for security agents should be considered together. The development of new business model is required for preparation against market stagnation and the development of new commodity to secure consumer for housing service rather than commercial facility service. for the purpose of those, new commodity related to home-network system and video surveillance system could be considered, also new added service with network between security company and consumer for a basis is to be considered.
