Since the career path is not fixed, rather changing over time, it is necessary to study the career development in adolescence. Thus, using the 11th wave data of the Korean Education & Employment Panel (KEEP), this study attempts to categorize the change of youth career development over time and verifies how those categories have effects on labor market outcomes, including income and job satisfaction. For this purpose, this study applied the two-part growth mixture model and conducted the Lanza approach analysis. The results of the study show that adolescent's career development can be categorized into five different patterns, including the career indecision group. Moreover, the group with a high level of career development has greater achievement of the labor market outcomes. Detailed explanations and implications of these findings are discussed in the paper

Όμλ₯Ό ν΅ν΄ 보μμ΅λλ€.Recently, an electronic version of a Mach-Zehnder interferometer has been realized using the quantum Hall edge state. The interferometer allowed experimental studies of the electron-electron(e-e) interaction effects on the electronic coherence in chiral one-dimensional (1D) systems. In this thesis, we study the electron transport in chiral systems by using bosonization technique with special emphasis on the electronic decoherence due to the e-e interaction.An electron above the Fermi energy interacts not only with the other electrons above but also with electrons below . In this thesis, we focus on the effect of the latter interaction. As a simplest case for the latter interaction effect, we consider a situation with a single electron above and examine its interaction with the filled Fermi sea. More specifically we study the evolution of a single-electron packet of Lorentzian shape along an edge of the integer quantum Hall regime, which may form a simple 1D chiral system or an electronic version of a Mach-Zehnder interferometer. For a simple 1D chiral system, we find that the interaction distorts the packet shape due to the generation of electron-hole excitations. However, as the interaction strength becomes larger, we find surprisingly that the distortion becomes weaker and eventually the Lorentzian packet shape is recovered. We find interesting interaction effects also in the Mach-Zehnder interferometer. When two arms of the interferometer have the same interaction strength, we find that as the interaction strength increases, the visibility of the interference initially decreases from its maximum value at the non-interacting limit. But as the interaction strength enters the strong interaction regime, the visibility begins to increase and eventually saturates to its maximum value. We attribute this unexpected result to the suppression of particle-hole excitations in the strong interaction limit. Also, we argue that this counterintuitive result is common to various types of long-range interactions
