The study investigated the relationship between subjective socioeconomic status (SES) of 508 Korean adults and their perception of justice (distributive and procedural justice for self and general others), and verified whether there is a moderating effect of age (20s versus 30s and over). A self-report survey on SES and perception of justice was conducted. Then, using the SPSS 27 and PROCESS Macro 4.0 program, a correlation analysis looking into the relationship among the study variables was performed along with the ANOVAs comparing the mean differences of study across age-groups to support the group division criteria. Next, a moderation analysis was conducted. The main results of this study are as follows. First, the participants' SES showed a positive relationship with all sub-factors of justice perception and a negative relationship with age. Second, age had a inverse relationship on distributive justice for self and general others, and procedural justice for self, but a non significant relationship on procedural justice for general others. Third, when looking into the mean differences of the research variables according to age, the 20s had different characteristics compared to the 30s and over. In comparison, there were no significant differences within the 30s and over group. Fourth, the moderating effect of age in the relationship between subjective SES and perception of justice was positively significant in the case of distributive justice for self and procedural justice for general others. In the case of distributive justice for self, the positive slope of the graph in which subjective SES predicts distributive fairness for self was steeper in the 30s and older group compared to the 20s. Regarding the procedural justice for general others, subjective SES was not a significant predictor in the 20s group. However, SES positively predicted procedural justice in the 30s and older group. This study is meaningful since it suggested age differences in subjective SES and perceptions of justice by revealing the different relationship patterns of subjective SES and perception of justice according to age.

본 연구에서는 해안가 암반대수층에서 전기전도도의 수직적인 변화를 관측하여 조석에 의한 해수와 담수 전이대의 특성을 파악하였다. 연구지역은 부경대학교 대연캠퍼스 주변 해안대수층이며, 응회질퇴적암과 안산암 및 안산암질 화산각력암 등이 분포한다. 연구에 이용된 지하수 관측공 (PK1공)은 부경대학교 대연캠퍼스 내 기숙사 동측에 위치하고 있다. 지하수공의 개발심도는 지표 면하 120 m, 케이싱은 지표면하 19 m까지 설치되어 있으며, 내경은 0.2 m로서 해안가에서 180 m 정도 이격되어 있다. 해안대수층 내 해수와 담수 전이대를 파악하기 위하여 관측공 내에 TLC Meter(Model 107, Solinst)를 삽입하여 전기전도도의 수직적인 변화를 지하수공 내 심도 50 m 까지 측정하였다. 전기전도도의 수직적인 관측은 썰물(low tide)일 때, 썰물에서 밀물(high tide)로 될 때 및 밀물일 때로 나누어 총 3회 수행되었다. 전체적인 전기전도도의 분포는 썰물일 때 $630{\sim}47300{\mu}S/cm$, 썰물에서 밀물로 되는 시기에는 $672{\sim}61900{\mu}S/cm$ 및 밀물일 때는 $678{\sim}67900{\mu}S/cm$로 나타났으며, 따라서 밀물일 때가 썰물일 때보다 전기전도도의 농도가 높은 것으로 나타났다. 해수와 담수 전이대의 분포는 썰물일 때 약 $20{\sim}50\;m$, 밀물일 때 약 $20{\sim}38\;m$ 정도로 나타났으며, 이는 밀물 시 해수의 침투로 인해 전이대 하부구간의 농도가 상승하였기 때문이다. 해수와 담수 전이대의 구간을 세분화하여 분석하기 위해, 담수가 우세한 전이대, 주 전이대 및 해수가 우세한 전이대 구간으로 구분하였다. 담수가 우세한 전이대는 썰물과 밀물일 때 모두 지표면하 $20.0{\sim}25.5\;m$ 구간이었으며, 주 전이대에서는 지표면하 $25.5{\sim}25.7\;m$ 정도로 나타났다. 그러나, 해수가 우세한 전이대에서는 썰물일 때 지표면하 $25.7{\sim}50.0\;m$ 구간, 밀물일 때는 지표면하 $25.7{\sim}38.0\;m$ 로서 전이대의 폭이 19 m 정도의 차이를 보였다. 본 연구를 통해 해안가 암반대수층에서 해수와 담수의 전이대는 조석에 의해 영향으로 인해, 썰물 시의 전이대가 밀물에 비해 그 폭이 더욱적음을 확인할 수 있었다.
