The objective of this study is to establish the new evaluating method of tinnitus and to evaluate the effect of acupuncture therapy. Fourteen patients with tinnitus were studied. The patients answered the questionnaire designed to identify and describe the subjective symptoms of tinnitus and discomfort in daily life due to tinnitus. After acupuncture therapy, the survey was conducted again among the patients and we evaluated the difference between pre-acupuncture therapy and post-acupuncture therapy. 1. Precipitating factors of tinnitus among the patients group consisted of 14 members were stress, noise, drug, overwork, URI, and otitis media in order. 2. Significant improvements in subjective symptoms of tinnitus and discomfort in daily life after acupuncture therapy were identified among the patient group of 14 members 3. Patient group of 14 members were divided into 2 groups by digestion status: patients who have poor digestion and patients who have good digestion. The patients who have good digestion showed significant improvement both in subjective symptoms of tinnitus and in discomfort in daily life after acupuncture therapy. 4. Patient group of 14 members were divided Into 2 groups by urination and defecation status: patients who have poor urination and defecation and patients who have good urination and defecation. The patients who have good urination and defecation showed significant improvement both in subjective symptoms of tinnitus and in discomfort in daily life after acupuncture therapy. 5. Patient group of 14 members were divided into 2 groups by sleeping status: patients who sleep well and patients who don't sleep well. The patients who sleep well showed significant improvement both in subjective symptoms of tinnitus and in discomfort in daily life after acupuncture therapy. This study shows that the subjective symptoms of tinnitus and discomfort in daily life due to tinnitus are involved in urination and defecation factor, sleep factor, and digestion factor. This study also shows that acupuncture therapy is effective in improving the subjective symptoms of tinnitus and discomfort in daily life due to tinnitus.

The purpose of this study was attempted to understand the substance and meaning of menopause experienced by women through informal interviews with oral consent. The informants were 6 perimenopausal women of 50-55 years old who are executing menopause. Colaizz's analytical method, a type of phenomenological analysis, was used to analyze data recorded by audiotape. One professor and a master's degree student who understand phenomenology, and the one who has a master of arts examined the validity between the meanings composed of the clusters of themes. Findings were turned out to be valid through validation process as the last step. The meaning of menopause implied both 'concept about menopause' and 'menopause as a time of change'. Menopause was mostly considered as cessation of menstruation as a physiological, natural, and normal process by aging. However, some people regarded menopause as a loss of youth and womanhood and lessening of every function of the body. Menopause as the time of changes means 'the period of' 'hormonal changes' such as change of menstruation, hot flushes, perspiration, and palpitation ; 'body function changes' of visual acuity, physical strength, sleeping, digestion, thoughts, bone and joints, skin sensibility, sexual pattern and intelligence ; 'emotional changes' such as anxiety, loneliness, gloominess, and nervousness. Menopause is a turning point on the women's life cycle accompanying various kind of changes and health problems. Therefore it is inevitable to develop strategy helping menopausal women pass through the critical successfully by adapting and coping with their critical period toward the healthy and better quality of life individually rather than putting them all into the standardized hormonal replacement protocol.

이동 애드혹 망을 구성하는 노드들은 일반적으로 배터리 전력을 사용하기 때문에 이들의 에너지 소모량을 줄이는 연구들이 각 계층에 대해 이루어져 왔다. 매체 접근 제어 프로토콜로 많이 이용되는 IEEE 802.11 DCF에서도 전력 절감 모드가 정의되어 있으며, 노드들은 동기화된 상태에서 주기적으로 활동 상태와 휴면 상태를 반복한다. 활동 상태 동안 서로 전송할 메시지가 있는지 여부를 이웃 노드에 공지하고, 전송에 관여하게 될 노드들은 계속해서 활동 상태로 머물러 필요한 송수신을 하는 반면, 그 외의 노드들은 다음 주기까지 휴면 상태에 들게 된다. 대부분의 기존 연구들은 보다 많은 전력 절감을 위해 휴면기간을 최대화, 최적화하는 것에 초점을 맞추었다. 그러나, 이로 인해 메시지들이 한 주기 당 한 홉씩 전달되어 결과적으로 매우 긴 전송지연을 초래할 수 있다는 것은 지금까지 간과되었다. 본 논문에서는 IEEE 802.11 DCF의 전력 절감 모드에서 빠른 속도로 전체 망으로의 플러딩을 수행할 수 있는 개선된 프로토콜을 제안하였다. 고정된 길이의 활동 상태 기간 동안 이웃 노드뿐 아니라 최대한 멀리까지 공지를 전달하게 하고, 동시에 많은 구간의 노드가 깨어 있게 함으로써 그 이후의 데이타 메시지 전달 속도를 높인다 시뮬레이션에 의한 실험 결과, 제안된 알고리즘은 IEEE 802.11 DCF 전력 절감 모드와 비교해 약간의 추가 에너지 소모로 플러딩 전송 지연을 최대 80% 이상 감소시켰으며, 플러딩 트래픽이 있을 경우의 유니 캐스팅 전송 지연 또한 약 50% 만큼 감소시키는 성능을 보였다.
